    Fluoride emissions monitoring in aluminum smelters

    Production of aluminum from its ores at aluminum smelters results in carbon dioxide CO2, carbon monoxide CO, sulfur dioxide SO2, and hydrogen fluoride HF gas emissions during the electrolytic process phase to the atmosphere. The gas emissions need to be monitored. Typically the smelters have emission limit values (ELVs) for sulfur dioxide and hydrogen fluoride emissions. These emissions should be measured accurately and with good precision, to ensure the smelter does not exceed its emission limit values. In...

    Laboratory instruments solutions for environmental industry

    The environmental challenges require internationally accepted standards, in which limits and test methods are defined. Metrohm instruments and applications comply with a lot of international environmental standards. Substances introduced into the environment are distributed among the environmental compartments water, soil (sediment), and air, as well as among the organisms living in them (biosphere). Only if we know the type and quantity of these contaminants can we protect the environment and its inhabitants.

    Mercury determination in natural gas

    Introduction

    The natural gas is a significant source of ingres s of mercury in the environment. The typical mercury concentration in natural gas may vary from 0.01 to 200 μ g/m3 . Mercury, being present in hydrocarbon gas, initiates corrosion of pipelines and catalyst poiso ning during gas transportation and processing, and these effects have serious implications for the gas-processing industry.

    Monitoring solutions for the De-NOx plants

    In recent years the number of Selective Catalytic Reduction (SCR) and Selective Non-Catalytic Reduction (SNCR) plants for De-NOx have increased significantly. Continuous analysis of NOx prior to the de-NOx plant is often required to measure the concentration generated by the combustion process. This may be required to provide feed-forward to the Ammonia/Urea injection system and also to allow the effectiveness of the reduction process to be assessed. Continuous analysis of NOx post-reduction is required to...

    Gas Detection Solutions for GHG Monitoring

    Most sources of fugitive emissions are from multiple points rather than single point sources. So, open path area or perimeter monitoring provides more meaningful fugitive emissions data than an array of point sensors or a program of grab sampling. Point measurements may underestimate emissions because of missing locations with high gas concentrations, or conversely overestimate because they are located in areas of high concentrations. Grab sampling programs typically check only a small percentage of potential...

    Carbon Dioxide Monitoring for Indoor Air Quality

    Introduction: Accurate control of critical indoor environmental parameters is not only essential for the well-being and comfort of building occupants, but also has a major impact on energy efficiency. A multitude of parameters can affect indoor air quality (IAQ) from gases such as carbon dioxide, carbon monoxide and volatile organic compounds to particulates, humidity and bacteria such as legionella. Carbon dioxide is one of the greatest variables affecting indoor environmental quality since it is produced by...

    Gas Detection Solutions for Aluminium

    Primary aluminium smelting generates large amounts of hydrogen fluoride gas (HF). Worker safety and ambient air quality concerns require that HF be monitored at several locations in smelters. Traditionally, a variety of chemical sampling methods have been used for HF monitoring in and around smelters. However, these methods are labour intensive and require ongoing maintenance and consumables. During the past decade, laser based HF analyzers have been replacing the traditional methods. Laser analyzers are...
