Mercaptans or THT are added to natural gas to make it smell and to make it detectable by the human nose (odorization process and odorization control in pipes).
energyMEDOR ppm: 30 years’ experience.The compounds usually used to odorize natural gas vary from one country to another but are usually:
Ter Buthyl Mercaptan (TBM)
Analyze H2S and mercaptans concentration in natural gas (ppm).
Humidity control is an important factor for stable and predictable pharmaceutical production. From R&D labs to bulk production, humidity can affect both the chemical and mechanical properties of formulations, which can lead to quality issues and Good Manufacturing Practice (GMP) challenges. Laboratory and pharmaceutical product dehumidification systems can be the right solution to help prevent moisture issues during the production process for tablets, capsules, powders, and strips.

Cracking in a refinery is a process where the long organic chains in oil are broken to produce shorter chain organics that are more valuable than the oil. Fluid catalytic cracking (FCC) has generally replaced thermal cracking of petroleum hydrocarbon feed stocks. FCC produces more gasoline with a higher octane rating. FCC’s byproduct gases are more olefinic and valuable than those produced by thermal cracking.
The Clean Air Group, LLC has provided many scrubbers (venturi type, ejector type, packed towers) for the chemical plant area of refineries. These have treated pollutants such as elemental sulfur, maleic anhydride, pthalic anhydride, ethylene oxide, hydrogen sulfide, etc. Our venturi scrubbers can be effectively utilized to handle the off-gases from FCCUs. Other specialized applications (for instance using Stretford Solution in an Ejector scrubber for high efficiency H2S removal) are not unusual for Clean Air...
The screenings cause considerable problems during disposal. In its untreated state, it is very moist and still contains a considerable proportion of easily degradable organic matter, which can lead to unpleasant odours due to spontaneous decomposition processes. In a sewage treatment plant, pieces of wood, plastic foils and other heavy materials are fed in via the waste water inlet. These are collected with the screenings in front of the screens and are then removed from the waste water stream during the screen...
The shipping industry is continually experiencing regulatory changes driven by increasing environmental concerns, resulting in ever-tightening regulations restricting sulfur (S) emissions from ships' fuel. It has been announced by the UN's shipping agency that the new sulfur IMO 2020 (International Maritime Organizations) guidelines for the sulfur content of marine fuel (bunker fuel) at sea will drop from 3.5 wt% to 0.5 wt% in early 2020. The sulfur content of traditional bunker fuels used in the shipping...
The PetroAlert Model 8900 combines the selectivity of gas chromatography with the sensitivity, broad dynamic range, and hydrocarbon selectivity of a flame ionization detector (FID) providing fast analysis of C1-C5 hydrocarbons and Carbon Dioxide required in Mud Logging for Oil & Gas exploration. The PetroAlert Model 8900 uses a dual column configuration with timed backflush to vent which is used to strip off moisture and C6+ hydrocarbons. A pre-cut column is used in series with the analytical column. At...
From portable hand held battery operated to rugged field deployable, military organizations worldwide rely of HI-Q air sampling systems & accessories during research, development, test and evaluation (RDT&E) and for reliable protection of personnel from Nuclear Biological Chemical Threats. HI-Q’s emergency response air sampling kits have offered the Defense & Military Industries a way of recognizing, determining and identifying the presence of harmful Biological & Nuclear Threats.
Deposits and corrosion as well as undesired emulsion, foam and toxic gases impact the operation and the occupational safety in refineries. Kurita provides tailored treatment concepts to increase the operational and the occupational safety. Our product lines and technologies are based on decades of experience in process treatment and they contribute to reduce your total operating costs.
MOCON’s Baseline® Series 9100 Gas Chromatograph equipped with a photoionization detector (PID) provides a quick, cost effective quantitative analysis of IPA and acetone in air at levels in the ppb and sub-ppb range with no preconcentration necessary.
Isopropanol and acetone are detected and accurately quantified to sub-ppb levels in under 3 minutes with ethanol producing no interference. The instrument is sensitive to below 5 ppb for both IPA and acetone employing the MOCON Baseline® standard PID or 0.1 ppb...
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.
In the mineral processing industries, such as calcination or catalysts production, solid intermediates and products are regularly handled in the fine powder form. There is a need to recover these powders from the exhaust streams of calciners, fluid bed dryers, incinerators, and storage silos, often at critical temperature conditions. Client`s needs include an efficient cyclone either for minimizing the escape of particles to downstream sections of the process at very high temperatures or to recover the maximum...
The measurement of pollutants such as O3, NO, NO2, CO, SO2 and HC to ppb’s and ppm’s require very sensitive analysers. Over the time or according regulations and devices requirements, calibration operations are required for each measured compound. As low concentration gas standards are expensive, may be unstable or not storable, like for ozone, on-site reference gas generation with Sonimix calibrators reduce costs, logistics troubles and keep analysers performances at their higher level.
Munters provides optimal protection of film, tapes, documents, books and artifacts in archives, museums, libraries, storage tents and self-storage facilities by creating and maintaining a controlled and constant storage climate around the year.

The content of WEEE (electrical and electronic waste) gives recyclers various initiatives for recycling. It contains hazardous substances, such as lead, mercury or certain flame retardants, as well as precious metals like gold and silver. In 2012 approx. 64,900.000 ton electronic goods where produced and 49.000.000 ton electrical and electronic waste (WEEE) was generated. As the amount of sold electronic goods rise, the amount of WEEE rises. It is vital that this waste is taken care of properly.
The ambient air in clean air rooms needs to be constantly monitored for the safety of workers and of the production according to the environment. A clean air room is a room where the concentration of particles is controlled in order to minimize the introduction, the generation, retention of particles inside, for instance for chip production or the production of medicines.
