Description: Flammable gases also have a temperature where ignition will take place, even without an external ignition source such as a spark or flame. This temperature is called the Ignition Temperature. ...

Description: Some gases are poisonous and can be dangerous to life at very low concentrations. Some toxic gases have strong smells like the distinctive 'rotten eggs' smell of H2S. ...

Description: Under working conditions, structured catalysts exhibit spatial and temporal distributions of the chemical species and temperature, that often lead them to operate under sub-optimal conditions. ...

Description: Evolved gas analysis techniques can be used to provide important information about decomposition or desorption processes when coupled to thermal analysis techniques such as DSC, TGA, and DTA. Mass ...

Description: By automating damper controls on ovens, as much as a 50% reduction in fuel costs can be realized. As the cost of fuel increases, so do the concerns about energy optimization and safety. This ...

Description: This white paper discusses how to safely use flammability monitoring to effectively automate damper controls and reduce the costs of owning and operating ovens and dryers. ...

Description: The development of new gas detection technologies and advances in fire and gas safety methodologies have prompted a new thinking about the role of technology diversity in system effectiveness. Like ...

Description: Automation dealers are continuing to gain business that was once reserved only for specialty and industrial contractors. It's a trend that is accelerating very rapidly, and the fastest growth is in ...

Description: Low level detection of 1,4-dioxane is required in many labs. The detection limits change with regulatory requirements and can vary from state to state and country to country. As instrument sensitivity ...

Description: Oil refineries are some of the largest producers and consumers of hydrogen gas. Hydrogen plays a pivotal role in a whole host of refining operations, from hydrocracking - the reduction of heavy gas ...

Description: Electrical equipment sometimes must be installed in areas where combustible vapors and gases are used or may be present. These are commonly referred to as "hazardous locations", and are defined by the ...

Description: Pharmaceutical facilities use a variety of hazardous gases and solvents in their production processes. Whenever these substances are transported, processed or stored, the potential risks are high for ...

Description: The global importance of SIL (Safety Integrity Levels) has grown substantially in the oil/gas, petrochemical and other process industries over the last 10 years. However, for many end users, systems ...

Description: Low ppb detection limits for contamination in cylinder gases have been achieved with gas chromatography using a modified gas injection system and megabore capillary columns with a variety of detectors ...

Description: Publicly owned treatment works (POTWs) collect wastewater from municipal, commercial and industrial facilities, transport it through a series of contributor pipes, known as a collection system, and ...

Description: This technical note assists operators in selecting a solvent vapor monitoring system that meets the requirements of NFPA 86. The system consists of three integral parts: *?The gas sample system that ...

Description: The National Fire Protection Association (NFPA) establishes fire safety standards, including standards for the safe operation of processes. NFPA 86, the Standard for Ovens and Furnaces, addresses the ...

Description: When designing a combustible gas safety monitoring system for oil/gas, petrochemical or other applications, how do you decide whether to use infrared or catalytic gas detector technology? Both sensing ...

Description: Many substances emit vapors that have potential to cause fire or explosion when mixed with air and a source of ignition. The minimum concentration of a substance needed to support combustion is known ...

Description: To develop an appropriate strategy for the implementation of a combustible gas detection system, a basic understanding of the properties of combustible materials is necessary. In our discussion we ...

Description: Several different sensor technologies may be used to detect hydrocarbons, including: catalytic; photo-ionization; infra-red; gas chromatography; and flame ionization. Of these possibilities, flame ...

Description: Continuing advances in infrared technology have resulted in fail-to-safe hydrocarbon gas point detectors that continuously monitor combustible gases and vapors within the lower explosive limit (LEL) ...

Description: Industrial fires and explosions happen more frequently than most people think. They cause downtime, property damage, injury and sometimes death. These fires and explosions result from a dangerous ...

Description: Most pulp managers have serious concerns about the safe incineration of non-condensable gases collected from digesters, reactors and other sources in the pulping process. ...
