TOPAZ Cerium – Rare Earth

Rare Earth

rare earth element (REE) or rare earth metal (REM) is one of a set of seventeen chemical elements in the periodic table, specifically the fifteen lanthanides, as well as scandium and yttrium. Scandium and yttrium are considered rare-earth elements because they tend to occur in the same ore deposits as the lanthanides and exhibit similar chemical properties.

Despite their name, rare-earth elements are relatively plentiful in Earth’s crust, with cerium being the 25th most abundant element at 68 parts per million, more abundant than copper. They are not especially rare, but they tend to occur together in nature and are difficult to separate from one another. However, because of their geochemical properties, rare-earth elements are typically dispersed and not often found concentrated as rare-earth minerals in economically exploitable ore deposits.

Uses of Rare Earth ElementsRare earth metals and alloys that contain them are used in many devices that people use every day such as computer memory, DVDs, rechargeable batteries, cell phones, catalytic converters, magnets, fluorescent lighting and much more.

Most of us use rare earth elements every day – without knowing it. These little-known and fascinating elements make modern electronics possible.

Mining Rare Earth

Rare Earth Minerals Processing. There are two major REE ore minerals from which predominantly LREE can be extracted with relative ease: bastnaesite and monazite. Bastnaesite, a fluorocarbonate mineral and monazite, a phosphate, contain predominantly either cerium, lanthanum or yttrium.

The run of mine material is passed through a cascade of physical processing steps including crushing, screening, grinding and flotation finally producing a bastnaesite pre-concentrate from which products with different REO contents are derived in subsequent thermal and chemical processing steps.  The REE mineral concentrate is digested in hydrochloric acid and the resulting REE laden liquor is passed through a sequence of solvent extraction with several mixer-settler steps. Final products of this element-selective extraction processes are either separated REO or other products following customer requirements.

Online Monitoring in Rare Earth Minerals Processing

The TOPAZ Rare Earth fulfils the requirements of the REE mining industry with the measurements of three key compounds:

Rare earths analyser

The online analysis of REE in condensate water, cooling tower and discharge water enables early leak detection along the mining process. Contaminated cooling water and condensate must be diverted and treated in WTP prior to be discharged. The TOPAZ Rare Earth from SERES Environment is specifically designed for to meet the REE industries in terms of environmental compliance and Process control.

Ammonium Bicarbonate analyser

Ammonium bicarbonate is used to precipitate the solution of cerium 4, the title of this solution, principally made from NH4 and CO2, determines the quality of the precipitate.  Accurate and fast monitoring of Ammonium Bicarbonate enables automated plant operations and optimal dosing.

Tank Headspace Monitoring Systems – THMS

Applications

in the Oil and Gas industry.

Water treatment plant in refineries and other oil and gas processes requires the use of tank for storage purposes and as part of the wastewater management plan. The composition of the air confined in the tank headspace provides a good indication of the level of contamination in the wastewater influents. Monitoring gas in tank headspaces also becomes mandatory when it comes to managing oils contaminated water. Explosion risks but also the corrosion and degradation factor are controlled with the blanketing whose automation can largely be optimised by the online measurement of gas concentrations in the headspace. Moreover there is a large number of compounds that will  adduce plant operators detailed information with regards to filtration and decantation processes.

Tank Blanketing Automation

Tank blanketing is the process of filling the headspace in storage vessels and reactors with an inert gas, usually to protect its contents from exploding, degrade but also to protect equipment from corrosion. As oxygen and moisture in the air can be undesired in numerous processes and applications, blanketing is done in a wide range of industries, varying from petrochemicals to food and beverage, pharmaceutical to pure water. Inerting is done for similar reasons but is not limited to storage tanks and reactors only. Any confined space can be sparged with an inert gas to create the desired atmosphere. This ranges from packing food under protective atmosphere to increase shelf life to lowering the oxygen concentration in rooms where welding takes place to reduce risk of fire.

Risks Management

Wrongly engineered or poorly maintained blanketing systems may lead to serious incidents, degraded plant operations and pollution events. A malfunctioning may cause the tank to implode or causes the leaking of air into the tank, which, as mentioned, can have consequences with regard to product quality and, depending on the stored product, can seriously increase risk of explosion.

One way to increase safety and reduce the use of blanketing gas (nitrogen, air…) simultaneously is to control inertisation as a function of gas concentration in the headspace. Depending on the product and the reason for blanketing and inerting, there are tolerances when it comes down to the maximum allowable oxygen, VOCs or other combustibles concentration. Certain monomers require zero percent oxygen to prevent polymerization. Others require a small amount of oxygen for the same reason. In the case of explosion protection, the oxygen concentration does not necessarily need to be zero. In fact for all solvents a so called limiting oxygen concentration exists. Below this concentration there is no risk of explosion. It is obvious that controlling the tank headspace purge based on the concentration will seriously cut nitrogen or other blanketing gas costs. Furthermore the measurement of gas concentrations in the tank headspace provides an important safety parameter.   Thresholds such as Limiting Oxygen Concentration (LOC), Maximum Oxygen Concentration (MOC), Lower Explosive Limit (LEL) indicate application and gas specific limits in terms of concentration.

For example, two threshold values are established for the oxygen concentration in the tank headspace, well below the Limiting Oxygen Concentration; the Lower Intervention Level and the Upper Intervention Level. These two threshold values are the set-points that control the purging sequences. The moment the oxygen concentration reaches the Lower Intervention Limit, the nitrogen flow is intermittent. Purging of the vessel is resumed when the upper intervention limit is exceeded. This means that the inerting system keeps the consumption of nitrogen minimal while safe operation is ensured.

Analyser solutions

Depending on individual process conditions and solvent; O2, H2O and LEL are usually the main parameters of interest. However when odour control is implemented NH3, H2S and VOCs can be added to the monitored parameters.

To meet the needs of the waste recycling facilities, AquaGas offers a unique fully automatic solution for realtime measurement of gas concentrations in Tank Headspaces. AquaGas THMS features the association of a MAMOS multigas analyser fitted with a combination of 9 gas proprietary measuring cells with a field proven, robust and dedicated Exproof sampling train. The system can be multiplexed for controlling up to 4 tank headspaces. Both the gas sampling probe located at the top of the tank and the sample line are temperature controlled above the gas dew point. Depending on the application, the gas can also be fitted with the optional backflush, temperature sensor, insitu filter… The onboard PLC offers a large panel of IOs as required to handle blanketing regulator, breathing valve, safety relief valve…

The THMS is integrated in Australia by AquaGas for continuous and simultaneous measurement of VOC, NH3, CO, CO2, LEL, CxHy, H2S and O2 inside tank headspaces.

Advantages of AquaGas THMS

The AquaGas THMS is a cost efficient and safe solution available in a compact wall mount IP56 enclosure that totally eliminates the need for multiple sensors and probes. The sampling probe can be mounted directly into the vessel or blanketing gas discharge piping and is rated for high dust, moisture or solvents loads. A retractable filter assembly allows cleaning of the sampling probe without the need for dismounting the probe from its matching flange. Zero calibration is performed automatically on a daily basis while span gas calibration is only required quarterly. In very critical applications, the system can be equipped with redundant probes and or sensors for additional safety and self check purposes. Compared to traditional analyser technology, the AquaGas THMS is available at only a fraction of the costs. The most valued perceived benefit however is the significant increase of safety, enormous savings on tank maintenance as well as the optimised process operations.

Mine Water Online Analysers

 

The use of water in mining has the potential to affect the quality of surrounding surface water and groundwater. In response to environmental concerns and government regulations, the mining industry worldwide increasingly monitors water discharged from mine sites, and has implemented a number of management strategies to prevent water pollution. Water issues and management vary from site to site and must be addressed locally.

lagoa_vermelha_na_mina_do_losal_05

How mines use water

Mining operations use water for mineral processing and metal recovery, controlling dust, and meeting the needs of workers on site. The amount of water required by a mine varies depending on its size, the mineral being extracted, and the extraction process used. For instance, metal mines that chemically process ore to concentrate metals such as copper and gold use much more water than non-metal mines such as coal, salt, or gravel mines.

Although a large mining operation may use a considerable amount of water, the minerals industry overall consumes a relatively small quantity of water at national and global levels. Mining accounted for 4% of the water used in Canada in 2005, versus 60% for coal and nuclear electric power generation, 18.5% for manufacturing, 9.5% for municipal water supplies, and 8% for agriculture. Mining accounts for 1% of water used in the U.S., and 2-3% of the total water consumed in Australia.

The rate of water reuse and recycling in mineral processing is often very high at mine sites, especially in areas with arid climates. A number of innovative water conservation practices  are being developed and implemented to reduce water use.

Types of mine water

There are a number of classifications of mine water, which can vary in their quality and potential for contamination:

  • Mine water: refers to any surface or groundwater present at the mine site
  • Mining water: water which has come into contact with any mine workings
  • Mill water: water used to crush and grind ore, may contain dissolved minerals and/or metals
  • Process water: water used in the chemical extraction of metals, commonly contains process chemicals
  • Leachate: water which has trickled through solid mine wastes and may contain dissolved minerals, process chemicals, and/or metals
  • Effluent: Mining, mill, or process water which is being discharged into surface water, often after being treated
  • Mine drainage water: Surface or groundwater which flows or has the potential to flow off the mine site

Typically, all the mine water at metal mines is collected and stored in tailing ponds before being treated and released to surface water if necessary.

Syngas monitoring

Purpose of gas monitoring in DRI plant

The use of process gas online monitoring systems at locations such blast furnace gas outlet, converter off gas exhaust and coking gas outlet is very reasonable in order to analyse the fuel gases composition by measuring the concentration of  CO, CO2, O2, N2, CH4, and H2. There from the calorific value BTU and the Wobbe Index WI can be accurately calculated. Modern steel plants uses dedicated stationary online monitoring system to monitor the primary constituents of  Direct Reduction Iron process gases essential to have a full understanding of the process status and efficiency.

  • In particular, the energy content of the gases, as described by their calorific value, provides the user with important information about efficient firing of different plants in the steel mill (coking plant, sinter plant, rolling mill, etc.) or a nearby power plant.
  • High-calorific coke or natural gas is mixed with low-calorific converter or blast furnace gas in mixing stations. This is to adjust the calorific value of the mixture to the requirements of the subsequent consumer and to avoid discharging of valuable gases into the off gas.
  • The knowledge of the calorific value together with information about pressure and flow rate of the fuel gas enables the user to adjust a constant energy content of the mixed gas using an intelligent control system.
  • Furthermore, analysis data of the gas analysers are also used to determine the equivalent amount of oxygen that is required to run the combustion process. This results in a stoichiometric and uniform combustion and prevents soot production.

Monitoring locations

The number of monitoring points can vary depending of the degree of automation and optimisation desired by the plant operators as well as the type, quality and stability of the combustible used.

Monitoring locations in Syngas Plant often include

Syngas online monitoring systems

The use of advanced online monitoring systems installed in the heart of syngas processes usually requires integration into air conditioned analyser rooms or shelters to preserve the instruments from harsh plant conditions and corrosive atmospheres. The installation in an area protected from the weather also secures the data/instrument availability by providing permanent access to the analysers – if attendance is required for maintenance or diagnosis.

Systems certified for installation in explosive area (ATEX) may be required in some cases.

Reliable, accurate and application customised online monitoring systems are valuable in DRI and other syngas plants as they allow determining the quality parameters of blast furnace, coke and natural gas essential to process optimisation.

AquaGas Pty Ltd offers a broad range of portable and stationary monitoring systems specifically designed to handle syngas online monitoring requirements.

CEMS and process gas analyser

 

A new approach to continuous gas monitoring

The Mamos is a high quality stationary monitoring system for the measurement of up to 6 gases as well as gas temperature, ambiant and differential pressures (Gas Flow) in a large field of applications.

Designed to optimise performance/price ratio, small in size and yet very skilful analyser, the Mamos is the field proven alternative for large, intricate Continuous Emissions Monitoring Systems, as it does not fall behind them concerning functionality, abilities, reliability and is far ahead in terms of expenses.

AquaGas Multigas CEMS

Online monitoring made easy

Fully automated and packed with exclusive features, the Mamos concept enlarges monitoring possibilities and respond to the today’s demands in terms of accuracy, reliability and flexibility. Each analyser is supplied with its own sampling system. The entire system is mounted on a wall mount plate and designed for installation in industrial settings and rough environment. It has a modular construction, and offer a large panel of add-ons to match site specific application requirements. The Mamos minimises the installation and ongoing operation cost until now required to fulfil your monitoring needs.

MAMOS-Multigas-analyser-CEMS-features

Multigas

Depending of the gas matrix and components to be analysed, the Mamos can be fitted with up to 6 different sensors. The combination of technologies (NDIR, TCD, PID, Electrochemical) and the addition of separate gas channels into the same instrument empower flexibility in multigas applications. A unique feature is to allocate a gas channel to sensible sensors. Its design ensures the cells have a limited exposure to gases and therefore extends considerably their respective life-time.

Process gas and emissions monitoring in combustion plants, boilers, syngas, biogas, waste recycling facilities and associated filtration systems are typical applications for multiple gas channels configuration.

In Biogas, the primary gas channel holds the CO2, CH4, Osensors while an additional separate gas channel is allocated to sensible Electrochemical sensors, H2S for example. The two NDIR gas channels can then be used for CO and VOCs.

MAMOS-CEMS-Flow diagram-2

The Mamos offers multiple sensor and method configurations. Here are the measuring parameter for the most common gases. For other gases or different measuring ranges (MR), please consult us.
