    Benzene is a highly hazardous chemical known to cause serious health effects, including cancer, when exposed to high concentrations or for prolonged periods. Refineries often have workers in close proximity to benzene sources, such as storage tanks, process units, or transfer areas. Fenceline monitoring helps ensure that workers are not exposed to excessive levels of benzene, providing a safer working environment and minimizing the risk of occupational illnesses.

    Fugitive emissions are a significant source of pollution and produced by industry, refineries, energy production, and natural gas pipelines. 40 CFR § 63.658 fenceline monitoring was created to better protect and inform nearby communities, while also strengthening emission controls for flares, pressure relief devices, storage tanks, and delayed coker operations.  Its purpose is to reduce hazardous air pollutants by requiring the sites to sample along the facility property boundary to measure the ambient air concentration of a specific chemical at the property line of the manufacturing site.

    Refinery benzene fenceline monitoring plays a vital role in ensuring compliance with the Refinery Sector Rule (RSR), which is a set of regulations established by the U.S. Environmental Protection Agency (EPA) to reduce emissions and protect the environment and public health from harmful air pollutants emitted by petroleum refineries.

    CEMS is a critical tool for environmental monitoring because it provides continuous, real-time data on emissions from industrial processes. CEMS systems measure various air pollutants, including particulate matter, sulfur dioxide, nitrogen oxides, carbon monoxide, and volatile organic compounds. These pollutants can have significant impacts on air quality and public health, so it is crucial to monitor them continuously.

    CEMS provides real-time and continuous monitoring of emissions from industrial sources. This enables immediate detection and response to any deviations or exceedances of emission limits. Real-time data allows for timely corrective actions, minimizing the duration and extent of potential environmental impacts.  Continuous monitoring ensures that emissions stay within permissible limits and helps operators demonstrate compliance through accurate and reliable data. CEMS data is often used for regulatory reporting, reducing the risk of non-compliance penalties and legal repercussions.

    A gas flare is a gas combustion control used in petroleum refineries, chemical plants and natural gas processing plants.  flare stacks are primarily used for burning off flammable gas released by safety valves during unplanned over-pressuring of plant equipment. The emissions are made up of both inorganic and organic species.  Flaring releases methane, a potent greenhouse gas, into the atmosphere.  

    Flaring releases various pollutants, including greenhouse gases (GHGs) such as carbon dioxide (CO2), methane (CH4), and other volatile organic compounds (VOCs) into the atmosphere. Flare gas analysis helps quantify the emissions by measuring the concentration of these gases. Accurate emission quantification is crucial for evaluating the environmental impact, assessing compliance with regulatory requirements, and establishing baseline data for emission reduction efforts.

    Flare gas analysis allows for the assessment of flare combustion efficiency. Incomplete or inefficient combustion during flaring can lead to the formation of pollutants such as carbon monoxide (CO), nitrogen oxides (NOx), and soot. By analyzing the composition of flare gas, operators can evaluate the combustion efficiency, identify any areas of improvement, and optimize flare operation to minimize the formation of pollutants.

    Fuel gas, natural gas, and biofuels combustion processes can produce emissions containing hazardous substances, including volatile organic compounds (VOCs), carbon monoxide (CO), nitrogen oxides (NOx), sulfur oxides (SOx), and particulate matter. Monitoring and analyzing these gas emissions are vital to ensure compliance with emission regulations imposed by environmental agencies. Powerful gas analysis solutions enable accurate measurement, quantification, and monitoring of these emissions, ensuring that they fall within the permissible limits set by regulatory authorities.

    In the US, NFPA 54, National Fuel Gas Code, is the American National Standard (ANSI Z223.1) that applies to the installation of fuel gas piping systems, equipment, and appliances that are supplied with natural gas, manufactured gas, liquefied petroleum gas (LP-Gas) in the vapor phase only, LP-Gas–air mixtures, mixtures of these gases, and gas–air mixtures in the flammable range.  In Canada, CSA B149.1:20, Natural gas and propane installation code reflects the latest safety requirements and cutting-edge advances in industry technologies.

    Surface water and groundwater are not the same. Surface water refers to water that is found on the Earth’s surface in streams, rivers, lakes, and oceans. This water is exposed to the atmosphere and is vulnerable to contamination from various sources such as industrial activities, agricultural runoff, and municipal waste discharge.

    Monitoring surface and groundwater for contaminants is important to ensure that these resources are safe for human consumption, as well as for the health of the surrounding ecosystems. Contaminants can include a variety of substances, including chemicals from industrial activities, fertilizers and pesticides from agriculture, and bacteria and viruses from human and animal waste. By monitoring surface and groundwater for contaminants, we can identify potential problems and take action to protect public health and the environment.
