Total Reduced Sulfur (S) monitoring

by Ecotech Pty Ltd     based in Knoxfield, AUSTRALIA

Total reduced sulfur(s), which include hydrogen sulfide (H2S), methyl mercaptan (methanethiol, CH3SH), dimethyl sulfide (CH3SCH3), and dimethyl disulfide (CH3S2CH3), occur naturally in the environment and can also be present in numerous industrial gaseous streams – petroleum refining, natural gas extraction, and chemical operations like the pulp/paper industry. Hydrogen sulfide is the most prevalent of the total reduced sulfurs, and is commonly found in volcanic gases, marshes and swamps, wetlands and mud flats, sulfur springs and decaying organic matter. Additionally, hydrogen sulfide is produced by living organisms, including human beings, through the digestion and metabolization of sulfur-containing materials. It must be noted that sulfur dioxide (SO2), sulfur trioxide (SO3) and sulfuric acid mist are not included in the determination of TRS, as these are oxidized sulfur compounds and are permitted and monitored separately from TRS.

Odor Control for Pulp And Paper

by OMI Industries (OMI)     based in Long Grove, ILLINOIS (USA)

Pulp And Paper Production With None Of The Odor

Pulp and paper manufacturing is a notorious source of nuisance odors, often stemming from hydrogen sulfide, mercaptans and sulfur dioxide. Fortunately, Ecosorb® products offer a natural and effective solution to neutralize these odors and all others associated with the paper and pulp industry.

Gas Detection Solutions for Hydrogen Fluoride (HF) Safety

by Boreal Laser Inc.     based in Edmonton, ALBERTA (CANADA)

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 sensors distributed throughout the unit. However, these sensors are maintenance intensive and have relatively slow response times. In addition, a point sensor will not detect an HF release unless it is located directly in the area of that release. Electrochemical HF sensors also respond to chlorine, ammonia, and sulfur dioxide, resulting in false alarms.

Total Sulfur monitoring

by Ecotech Pty Ltd     based in Knoxfield, AUSTRALIA

Total Sulfur includes all the gases described within total reduced sulfur, as well as sulfur dioxide as these compounds are oxidised forms of sulfur. Exposure to sulfur dioxides, and other reduced sulfur based compounds can cause many harmful effects in humans including headaches, general discomfort up to death in large doses. Those with impaired heart or lung function and asthmatics are at increased risk. Sulfur dioxide, one of the major pollutants, is absorbed by soils and plants and captured within and below clouds and in certain circumstances can increase the acidity of rain.

Sulfur Dioxide (SO2) monitoring

by Ecotech Pty Ltd     based in Knoxfield, AUSTRALIA

Sulfur Dioxide (SO2) is the product of the combustion of sulfur compounds and causes significant environmental pollution. The main source of sulfur dioxide SO2 in the environment are from various industrial processes such as the burning of coal in power stations, the extraction of metals from ore and combustion of fuel within automobiles.
