AquaFID THC CEMS – Continuous Emissions Monitoring Systems

AquaGas supplies four AquaFID THC CEMS

For Sydney’s greater remediation project

AquaGas Monitoring Systems is proud to be part of a major remediation project taking place in the heart of Sydney’s next financial, tourist, cultural and entertainment precinct. This significantly large remediation project is now underway over the next three years to remediate on site 150,000 tonnes of contaminated fill material from a former gas plant.

One of the main actors in this project,  South Pacific market leader for the containment and filtration of hydrocarbons (sheen, gasoline, diesel and oils) and a range of other chemicals, has selected AquaGas Pty Ltd for the supply, installation and commissioning of the Continuous Emissions Monitoring Systems and Process Analysers at the remediation site.

To meet our client environmental monitoring requirements, AquaGas has offered a unique CEMS (Continuous Emissions Monitoring Systems) solution based on Gas Chromatography, the AquaFID. The AquaFID is a fully automatic THC CEMS integrated in Australia by AquaGas for continuous and simultaneous measurement of Total Hydrocarbons (THC), Non Methane Hydrocarbons (NMHC) and Methane (CH4).

The AquaFID key features includes the association of a field proven, robust fast loop heated sampling system from Ankersmid Sampling BVBA (Belgium) with a highly accurate M529H FID analysers from PCF (Italia).

The Exproof sampling system is fitted with extensive features such as calibration port as per international CEMS code and EN14181 for reliable continuous compliance monitoring.

The remediation projects are being strictly monitored in real time. Data is regularly reported to the EPA.

ENVIRONMENTAL MONITORING

Stack Testing

Ankersmid Sampling

APS Portable Gas Sampling System

The emission of pollutants resulting from a multitude of activities (industry, transport, …) alters the atmospheric composition and degrade air quality. Control of gaseous pollutant emissions in the atmosphere has become a major challenge for the protection of human health and the environment. To avoid these risks, the regulation has established discharge limits thresholds for certain pollutants and requires periodic inspections whose frequency depends on the type of activity (from 3 months to 3 years). Accredited stack testing companies are responsible for conducting short to medium term environmental compliance monitoring tasks in a wide range of industries and processes such as power plants and large manufacturing facilities including paper mill, foundry, waste recycling facilities,  refineries…

Prior to be analysed, the gas extracted from the discharge stack or process duct requires delicate conditioning which mainly consist of particulate filtration and moisture removal. Failure to achieve an efficient sample preparation can results in inaccurate measurements, loss of data or damaged equipment.

While stack testers and local authorities are continuously devoting time and knowledge to optimise the methods and protocols related to short to medium terms mandatory analysis campaign, ANKERSMID® has invested its long time expertise in developing the APS Portable Gas Conditioning Systems in direct collaboration with  leading stack testing companies.

As a result, ANKERSMID® Portable Sampling System APS provides stack testers with  features tailored to short term source testing in a robust and light weight design. The complete systems responds to today’s demand in terms of operation and compliance.

APP Portable Heated Gas Sampling Probe

The APP Heated Gas Sampling Probe is a light weight sampling gun enabling high temperature filtration directly at the sampling point.

Portable probe APP trans 2

The probe is heated up to 180°C in order to maintain the sample temperature above acid gases dew point. A filter element of 150 mm is integrated, suitable for most applications up to 1g of dust per cubic meter of emissions. Thanks to its design, the filter can be replaced or checked without the need of dismounting the probe. For applications where the dust load reaches 10 g/m³, a blow-back option can be fitted. Calibration gas can be injected directly into the probe through the calibration gas port according to emission monitoring standards enforcing test gas feeding via the probe’s filter element.

Indoor air quality

 

Air Quality in Submarines

 

The ProCeas® NAV

The ProCeas® NAV is designed for online monitoring of CO2, CO, Freon, H2S, H2, O2, Formaldehyde (…) in nuclear and conventional submarines. The ProCeas® NAV uses the OFCEAS method commercialized by Ap2e of France.

The OFCEAS system uses a high-finesse optical cavity to provide path lengths of tens of kilometres. Moreover the OFCEAS technology can also, in certain configurations, take advantage of broadband light sources to provide multi-component analysis, while offering improved sensitivity when compared with shorter path-length methods, such as Tunable Diode Laser absorption spectroscopy (TDLAS).

Area Monitors for Sterilant Gas

Hazards of sterilant gases

Since sterilant gases are selected to destroy a wide range of biological life forms, any gas which is suitable for sterilisation will present a hazard to personnel exposed to it. The NIOSH Immediately Dangerous to Life and Health values (IDLH) for the three sterilant gases are 800 ppm, 75 ppm and 5 ppm for ethylene oxide, hydrogen peroxide and ozone respectively.

For comparison, the IDLH of cyanide gas (hydrogen cyanide) is 50 ppm. Thus exposure to even low levels of sterilant gas should not be treated casually and most facilities go to great lengths to adequately protect their employees. In addition sterilizers (as with any mechanical device) can and sometimes do fail and leaks have been reported. Continuous gas monitors are used as part of an overall safety program to provide a prompt alert to nearby workers in the event that there is a leak of the sterilant gas.Steri-Trac Area Monitors - sterilant gas - AquaGas

Monitoring Sterilant

The monitor alarms are typically set to warn if the concentrations exceed the OSHA permissible exposure limits (PELs), 1.0 ppm for ethylene oxide and 1.0 and 0.1 ppm for OH&S and ozone respectively. The PELs are calculated as 8 hour time weighted average values.

In addition to providing continuous monitoring, the better gas monitors include a computer based data acquisition system provides automatic data logging to assist with compliance with OSHA’s regulations and impending alarms that allow users to rectify problems before they become a hazard.

There are several technologies that are commonly used for the detection of sterilant gases, the main three being electrochemical, gas chromatography and metal oxide semiconductor. All three technologies are suitable for ethylene oxide, but only electrochemical sensors are used for hydrogen peroxide and ozone detection.

For ethylene oxide, metal oxide electrochemical sensors provide a low cost, long life detector offer very good sensitivity, fast alarm response times and small size. ChemDAQ gas monitor manufacturers mainly use electrochemical sensors for toxic gases because of their many advantages.

Electrochemical sensors have traditionally suffered from a cross sensitivity problems with other vapours (alcohols are especially troublesome in health care). Cross sensitivity results in false alarms, unnecessary evacuations and eventually a loss of confidence in the gas monitoring system.

AquaGas - ChemDag - Steri-trac

ChemDAQ has developed a proprietary chemical filter that allows the ethylene oxide to pass through but removes most common interferent gases and vapours (including carbon monoxide, ethanol and IPA). The use of this filter allow the ethylene oxide to be detected with all the advantages that electrochemical sensors have to offer, but without the problems of cross sensitivity.
