Gas monitoring instruments and systems for print factories

by Gasmet Technologies Oy     based in Helsinki, FINLAND

Typical modern printing processes utilize solvent-based dyes. The evaporation of the dye solvents into the ambient air during the printing process may expose the workers to various chemicals. Depending on the type of solvents in case, the solvents have different long term exposure limits, which should be obeyed. Component specific measurements are necessary to protect the workers from exposure while avoiding unnecessary interruptions to the printing process from false alarms.

Fluoride emissions monitoring in aluminum smelters

by Gasmet Technologies Oy     based in Helsinki, FINLAND

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 addition several fluoride compounds may be produced in the electrolytic bath in the event of an oxygen shortage. These compounds include carbon tetrafluoride CF4, hexafluoroethane C2F6, sulfur hexafluoride SF6, and silicon tetrafluoride SiF4. These additional emission components are problematic, as they have high Global Warming Potential (GWP) values. The GWP is a relative measure designed to demonstrate how much heat a greenhouse gas (GHG) traps in the atmosphere. Emission of one kilogram of carbon tetrafluoride into the atmosphere today has the potential of heating the atmosphere as much as 7,000 kilograms of carbon dioxide over the next 100 years.

Measurement solution for formaldehyde FTIR measurement

by Protea Limited     based in Middlewich, UNITED KINGDOM

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 FTIR analyser have been proven in formaldehyde emission measurements over many years.

Measurement solution for soil chamber gas flux

by Protea Limited     based in Middlewich, UNITED KINGDOM

Closed chamber gas flux measurements can be made with Protea FTIR analysers to allow researchers in the field of atmospheric gas analysis from agricultural and livestock to measure evolved gases such as N2O, CO2, CO, NH3, and CH4. Nitrous oxide (N2O) and Methane (CH4) emissions from soil, plant and livestock are especially important gases to measure, given their high potential as greenhouse gases (GHGs). NH3, whilst not a greenhouse gas on the scale of N2O, CH4 and CO2, is a major emission from agricultural, such as after the spreading of liquid manure, and steps are required to measure and reduce the NH3 emissions and the effects they have on the ecosystem.

Measurement solution for acrylates speciation

by Protea Limited     based in Middlewich, UNITED KINGDOM

A customer had a requirement for continuous Ethyl Acrylate monitoring. The process operations emit multiple Acrylate species, all at low concentrations, but only Ethyl Acrylate being reportable to the EA under the terms of the IPC permit. A 204M FTIR analyser was deployed and a chemometric model was built specifically to target Acrylates, with the purpose of separating and accurately quantify the target Ethyl Acrylate species.

Integrated real-time gas analysis solution for electronic specialty gases industry

by CIC Photonics, Inc.     based in Albuquerque, NEW MEXICO (USA)

The company’s entry into the electronic specialty gas market originated in 1994-95 as a consequence of the semiconductor industry’s demand for increasingly higher purity gases from the major gas producers. The issue was then and remains today to be primarily moisture impurity levels in the cleaning, etching, and treatment gases used in wafer production. In that earlier period when common wafer sizes were 6” and 12”, the semi industry required moisture concentrations to be 250 to 500 ppb or better; with each year after that the industry tightened its requirements such that today the moisture specifications are 1 to 5 ppb or better.

Gas monitoring instruments and systems for phosgene monitoring

by Gasmet Technologies Oy     based in Helsinki, FINLAND

Phosgene COCl2 is a colorless gas. While it has been used as a Chemical Weapon Agent (CWA) in the past, currently this poisonous gas is also an important reagent in synthesis in the pharmaceutical and chemical industries. The plants using phosgene are typically equipped with gas sensors to detect leaks in the indoor ambient air. The critical situations arise when equipment in contact with the gas at the manufacturing facilities are serviced and maintained. As phosgene is very poisonous, even small gas pockets in serviced equipment may be dangerous to maintenance personnel. Gasmet™ FTIR Gas Analyzers are ideal tools to monitor point sources of phosgene. The measurement technology has high specificity, may be operated continuously, and has a fast response time.

Gas monitoring instruments and systems for anesthetic gases

by Gasmet Technologies Oy     based in Helsinki, FINLAND

The anesthetic gases and vapors which leak into the indoor atmosphere during medical procedures are considered waste anesthetic gases (WAGs). The exposure is of relevance to thousands of professionals in hospitals, operating theaters, patient recovery rooms, dental offices, and veterinary clinics around the world, who may be continually exposed to the waste anesthetic gases during their workday. Typical gases of concern include nitrous oxide N2O and several halogenated compounds in vapor form, such as sevoflurane, isoflurane, enflurane, halothane, desflurane, and methoxyflurane. Short-term exposure to these gases may lead to several symptoms, such as dizziness, headaches, fatigue, nausea. Long-term exposure to some of the anesthetic agents may result in sterility, birth defects, cancer, and liver and kidney disease.

Measurement solution for HF emissions from brickworks

by Protea Limited     based in Middlewich, UNITED KINGDOM

Brick kilns, as well as other plants such as ceramics manufacturers and fertiliser producers, are a major producer of hydrogen fluoride (HF) emissions. HF is highly reactive gas and seriously damaging to human health, so has strict emissions limits imposed by legislation. In addition to the effects to humans, emissions have been found to damage crops and fruit trees, as well as the general environment. The brick industry strives to reduce the amount of HF emissions and numerous projects have been carried out into the research and development of proposed process modifications that introduce ways to reduce hydrogen fluoride emissions via the latest technology such as filters and scrubbers.

Measurement solution for total volatile organic compounds (VOCs) via FTIR

by Protea Limited     based in Middlewich, UNITED KINGDOM

Total Volatile Organic Compounds (VOCs) is a common measurement required from industrial emissions. Commonly, a single measurement value is obtained through the use of a Flame Ionisation Detection (FID) analyser. The pyrolysis of the gas stream in a FID analyser allows it to make a measurement of the carbon content of the gas stream. FID analyser cannot indicate the relative abundances of different organic species in a gas stream and often have widely different responses for different gases. However, they are taken as the standard reference method for Total VOC emission measurements.

Gas monitoring instruments and systems for semiconductor manufacturing

by Gasmet Technologies Oy     based in Helsinki, FINLAND

In the semiconductor manufacturing industry, various perfluorinated compounds (PFCs) are used. The emissions of the PFC compounds into the ambient air are reduced by scrubbing of the exhaust gases from the process. In this process, the Gasmet™ FTIR Gas Analyzers can be used to measure the emissions into the atmosphere and also monitor the efficiency of the scrubbers. Typically monitored PFCs in the exhaust gas include carbon tetrafluoride CF4, trifluoromethane CHF3, and hexafluoroethane C2F6.
