The Road to Environmental Efficiency: Monitoring Nitrogen Oxides (NOX) and Hydrocarbons (CXHY) for Combustion Efficiency and Environmental Compliance.
Why Monitor Nitrogen Oxides (NOx)?
Nitrogen oxides (NOX) are toxic gases common to combustion processes that are highly regulated by state and federal Environmental Protection Agencies (EPA). Exceeding the environmental limit not only compromises worker health and safety, but may require supervisors to shut down a plant and/or pay a fine for noncompliance....
Combustion is a chemical process that involves the rapid reaction of a fuel substance with oxygen and heat. During this reaction new chemical substances, such as exhaust fumes, heat and light are created. There are many types of combustion including; complete, incomplete, smouldering, rapid and turbulent. Each process can differ due to the heat source and amounts of fuel or oxygen available.
Procal supply analysers to monitor many different applications from small combustion plants to large power stations. Examples include University Boiler Plants, Carbon Black Plants, Thermal Oxidisers and Community Heating Projects.
The accurate measurement of a gas mixture is essential to metal and mineral processing. Reliable measurements are needed to manage processes ranging from effective combustion control to optimized process control.
Fixed CEMS (Continuous Emissions Monitors) Measure at One Location
CEMS are fixed units that typically only measure from one sample location which is usually on a main centralized stack. This main stack is often fed by several separate emissions sources throughout the plant such as boilers, heaters, engines, ovens, and furnaces.
If the CEM is measuring emissions that are higher than the regulated or permitted limits, it can be difficult to determine the source of the high emissions which could be from...
When extracting and refining valuable geological materials from the earth (eg. limestone, aluminum oxide, gold), a variety of industrial combustion processes are required. The machinery used in these processes such as industrial engines, boilers, and smelters can emit highly toxic gases that are harmful to the environment and to human life. Using a portable emissions analyzer enables mining personnel to ensure personal and environmental safety, while optimizing the performance of the mining operation.
Chemical and 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 hazardous conditions. These substances must be continuously monitored to protect personnel and facilities from accidental releases or leakage. Our various lines of hazardous gas monitoring systems benefit the chemical and pharmaceutical industry in the following applications.
Hydrocarbon Processing is one of the most demanding industries in the world. High levels of productivity must be achieved while constantly maintaining the very highest safety standards. Effective gas analysis is a critical component of all HP processes, typically requiring a wide range of measurements to ensure the safe, optimized running of the process.
Many forklift trucks have internal combustion engines that burn propane, natural gas, diesel, or other fossil fuels. A portable combustion gas and emissions analyzer can be used to optimize combustion efficiency & maximize fuel savings, identify and quantify sources that can adversely affect safety and comfort in the work environment, and measure and reduce harmful emissions in the forklift engine exhuast gas.
