Common hazardous gases found in wastewater treatment plant facilities are hydrogen sulphide, methane, ammonia, carbon monoxide, chlorine and oxygen deficiency. Some facilities may also use ozone, chlorine dioxide or sodium hypochlorite with the chlorine during the sanitization treatment process. Furthermore, sulphur dioxide is often used to de-chlorinate the water once the treatment process is ...
The potential for exposure to hazardous gases is a concern in many workplace environments. To ensure the safety of the workers, equipment, and the facility, areas presenting a gas hazard should be monitored by gas detectors. Commercial buildings that share a warehouse with manufacturing and/or service work in the back and offices in the front are a prime place for harmful gases and vapours ...
An engineer repairs buried cables; a plant manager enters a small plant room; a contractor inspects the lining of a sewage pipe. All these personnel face a common danger, despite working in widely different industries. Gas-related injury poses a serious threat in any confined space where the free movement of air is limited. ...
Introduction An offshore worker ensures a vessel is safe to enter; a plant manager enters a small plant room; a contractor inspects the lining of a sewage pipe. All these personnel face common dangers, despite working in widely different industries. Gas-related injury poses a serious threat in any confined space where the free movement of air is limited. A confined space ...
The real benefits of refrigerant gas leak detection Following on from the last article, we feel that it’s natural to then discuss some of the practical reasons (cost savings) that will encourage the industry to take action and reduce their F-Gas emissions. Who requires refrigerant leak detection under the F-Gas proposals? There are a ...
Geotech’s first GA5000 analyser, manufactured three years ago, was recently spotted in the company’s calibration rig. This portable landfill gas monitor was the first production unit of the newly launched GA5000 gas analyser range and has prompted Geotech to look into the analyser’s life since then. The analyser was on its sixth service since manufacture, under ...
Introduction EP-IR is a new technology that provides opportunities for uncharted territories One of these territories is moisture analysis What limit of detection for moisture can be achieved? EP-IRGAS Encoded Photometric-Integrated Real-Time Gas Analysis Solution Incorporates an Aspectrics 128 channel ...
Nitrogen oxides NOx are pollutants that may have particular impact in terms of greenhouse gases, acidifying air etc ... issuance increased significantly since 1950 with the massive development of transport and industries. It therefore becomes necessary to provide measures always safer these pollutant gases, and to know the reliability of results. Currently, 60% of emissions of NO and NO2 are ...
Problem Statement The race for a system that can detect the lowest possible level of moisture is seemingly everlasting. As the race continues we have begun to explore the options of using an EP-IR spectrometer coupled with DID Photonics Integrated IR Source 4 Runner. Experimental Equipment The EP-IR spectrometer is vibration insensitive and runs ...
Fossil Fuel Power Generation Fuel fired power generation plants have several oil storage tanks for feeding fuel to the power units. Coal or gas fired power generation plants also have oil storage tanks to be used for start-up or as a back-up energy source. All ...
On December 19, 2008, EPA issued a final rule establishing a voluntary Alternative Work Practice (AWP) to detect leaks of volatile organic compounds (VOC) and hazardous air pollutants (HAP) from process equipment (FR Vol. 73, Number 246), thereby providing the regulated community additional flexibility in complying with leak detection and repair (LDAR) requirements. The AWP allows owners or ...
