Formaldehyde (HCHO) is the simplest aldehyde species and is present, or generated by, many sources (both natural and industrial). It is classed as a substance that is toxic and harmful to human health.
Reciprocating internal combustion engines burning natural gas are a source of formaldehyde emissions. There are strict tolerances imposed on operators of engines to ensure that formaldehyde is removed effectively and that formaldehyde emissions are below published limits. The only instrumental method for formaldehyde monitoring is FTIR, following procedures such as US EPA Method 320 and Environment Agency TGN M22. Protea’s FTIR gas analysers have been specifically designed to follow these methods and our...
Process control and emissions monitoring in a mineral wool plant is a challenge due to the presence of phenol and formaldehyde. To use an extractive system in this environment will demand a lot of maintenance. The OPSIS DOAS system is different and provides plants with an accurate analyser that will operate with a minimum of maintenance. The OPSIS DOAS system is based on a non-contact method using an optical measurement path that can operate across the duct.
Manufacturing and processing food products produces emissions that must be treated. Firstly, emissions produced by heat-treating raw materials should be treated, in particular carboxylic acids, formaldehyde and acetone.
One of the problems arising in wood processing and production of popular materials based on wood, such as plywood, wood-chip and wood-fiber materials (chipboard, hardboard, OSB) is removing harmful substances from the air. Emissions from these industries are characterized primarily by the presence of phenol and formaldehyde, and the level of discharge is significant, up to 100 000 m3/hour of contaminated air.
Removal of urea and phenol formaldehyde resin and fibers from sizing dye operations, particulate and blue haze emissions from fiberglass mat ovens. Removal of styrene emissions from fiberglass composite manufacturing operations.
