AquaGas Pty Ltd – Enews November 2016

We are delighted to announce the recent acquisition of several major projects in the field of Continuous Emissions Monitoring (CEMS) and industrial process control.


Continuous Emission Monitoring System

Prony Power Station in New Caledonia

AquaGas Pty Ltd, has been awarded a major contract for the supply, integration, installation and commissioning of two complete CEMS (Continuous Emission Monitoring System) used for compliance stack emissions monitoring of Prony Power Station located at one of the largest mining facilities located in southern hemisphere.

In this project, AquaGas has selected the LaserCEM (AP2E) and DR-320 R (DURAG) as the most suited technologies with regards to the application requirements and harsh monitoring conditions, providing the plant operator ENERCAL with the last generation of CEMS multigas analyser and dust monitors for online analysis of Particulates, HCl, SO2, NO, NO2, CO, CO2 and O2 at their two coal fired boiler facilities.

AquaGas scope also includes CDAS, Mcerts certified and state of the art data acquisition and reporting software suite. The CDAS software package ensures strict emissions reporting and clear environmental compliance.

The strong partnership with AP2E, expert in Laser Spectroscopy, and DURAG specialised in the field of environmental monitoring and process control has led to this first shared success, the acquisition of a capital reference for the LaserCEM in the field of power generation while enforcing AquaGas position in Oceania.

Prony Power Station is located on VALE mining site providing access to large port facilities for the supply of combustible. It consists of two 55 MW Alstom boilers (203 t/h – 87 bars – 515°C) equipped with Alstom turbines (85 bars – 500°C) and alternators (59 MVA – 11 kV) providing power for both the public demand and the needs of the large Nickel mining facilities.

Located close to the site and focused on customer satisfaction, AquaGas has implemented an efficient transfer of knowledge to the plant owner as well as to the local company ROBICAL assigned for the CEMS routine maintenance.


Continuous Emission Monitoring System

Caltex Lytton refinery in Australia

Caltex has recently approached AquaGas to perform a system expertise at their Lytton refining facilities near Brisbane.

The difficulties experienced by Caltex with their CEMS (Continuous Emission Monitoring System) had been related to the existing sampling method and resulted in a high maintenance level and unreliable monitoring operations.

Thanks to the customer feedback and following a couple of site visits, AquaGas has identified several ways to optimise the existing CEMS (Continuous Emission Monitoring System) sampling method. In order to secure the data availability and keep the maintenance requirements to their minimum, AquaGas Pty Ltd has supplied, integrated and installed a set of heated gas sampling probes:

  • ASP300

    At the boiler facilities, the ASP300 fitted with automatic blowback, calibration port in accordance with CEMS standards and a continuous soot removal system.

  • ASP400

    For the Thermal Oxidiser, the ASP400 equipped with automatic blowback, calibration port in accordance with CEMS standards and designed to handle high dust load as well as elevated process gas temperatures.

Both the ASP300 and ASP400 provide the plant operator with application specific features and innovative design resulting in a series of advantages:

  • Programmable back-flush sequences,
  • Calibration as per CEMS code,
  • Extended filtration surface,
  • Flue gas temperature measurement
  • Insitu filters – The ASP’s allows the inspection of the Insitu or “top filter” without the need for dismounting the probe (No fitters required for inspection or maintenance).
  • Adjustable temperature set point (set at 190 degree Celsius)
  • Continuous and automated soot removal performed directly at the sampling point

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.


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.
