In accordance with "Standard for pollution control on the municipal solid waste incineration" (draft), all existing and new the municipal solid waste incinerators need automatic continuous on-line monitoring of main ingredients in incineration flue gas. Monitoring projects should include at least HCl, SO2, NOx, soot, etc., but also need to detect CO and HF in some higher environmental requirements situations.

The consumption of scrubbing material in a scrubber is related to the mass flow of acid gases. Hydrogen chloride (HCl) and sulphur dioxide (SO2) are the major acid gases in an incinerator. By measuring the mass flow of SO2 and HCl in the raw gas going into the scrubber, it is possible to calculate the required quantity of scrubbing material.

A new EC regulation states that diesel engines need to have active cleaning with urea injection in order to reduce NOx emissions. In order to control the urea dosage, a reliable measurement system is required. OPSIS LD500 laser diode gas analyser for monitoring ammonia (NH3), has been tested and approved by German TÜV, in accordance with the EURO VI standard.

Ammonia is a notoriously difficult compound to measure accurately and reliably using standard chemical sampling techniques. The great advantage of the optical laser gas detection technique for quantitative ammonia monitoring is that the optical measurement does not affect the air being sampled – and so a true, undisturbed value for ammonia concentration can be determined. The very high resolution and specificity of the laser method also means that is no interference from other gases in the air (for example,...

Levels of hydrogen in dry chlorine are monitored in hydrochloric acid synthesis by means of AppliTek’s multi-wavelength IR analyzer system. With increasing concerns over safety and efficiency in the chlorine manufacturing processes, AppliTek has investigated the use of proprietary on-line analyzer systems to monitor and control the HCl synthesis. Each of these on-line analyzer systems has been selected to control a specific part of the burner, by using techniques such as multi-wavelength infrared, thermal...

Hydrogen chloride (HCl) is a colorless, sometimes slightly yellow, gas. It is an undesired environmental component that may be damaging to workers and the surroundings. Exposure limits have thus been established by industries to make sure that the workers operate in a safe environment. HCl monitoring is especially required for incinerators, coal-fired power plants, aluminum recycling and cement plants. Unisearch offers a reliable and easy-to-use HCl analyzer – the TDLAS-based LasIR system. Studies have...

Hydrogen Fluoride (HF) is a colorless gas that is used extensively in industrial applications. Fluoride monitoring is especially needed for aluminum plants that need to convert HF into fluorine for use in their processes. Any HF that escapes is a cost to the plant, so an HF analyzer is essential to keep track of and prevent the losses.

Protea was asked to supply a high level ammonia (NH3) measurement system for a waste water treatment plant. The reflux drums at the inlet to two ammonia stripping towers needed to be measured continuously. Protea designed a solution based around our Solus TDLAS analyser platform and a high level dilution system. The Solus analyser was configured for NH3 measurements in the range 0-500ppm. A dilution system incorporating special dilution probe and 19` control panel was installed before the analyser. This gave a...

Hydrogen Fluoride (HF) is a very useful chemical used in a variety of industries. However, HF is highly toxic with potential fatal consequences with exposure to humans, so facilities that make or use HF should exercise great care. Nevertheless, there is always the risk of leaks from process elements such as valves, pump seals and storage vessels. Tanker loading, transporting and unloading operations also provide opportunity for HF releases. Industrial processes that make or use HF typically have arrays of point...

Unwanted liquid hydrocarbon releases from oil refineries and pipelines, as well as transportation facilities are critical infrastructure integrity/safety and environmental health concerns. Real-time sensing of these releases has to deal with complex natural and anthropogenic targets usually containing a multitude of substances producing overlapping signals. Using Laser Induced Fluorescence (LIF), LDI LiDARs are able to deal with these complex environmental factors and still detect and quantify unwanted releases...

The purpose of determination of moisture in dry chlorine is threefold: prevent corrosion, prevent formation of ferric chloride and control the overall drying process. AppliTek offers two different solutions for determination of moisture: one traditional method by means of an amperometric phosphoric pentoxide (P2O5) electrochemical cell, or a more advanced technique based on tunable diode laser technology (TLDS). Both analyzer systems are installed in a compact protective corrosion resistant cabinet.
