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).
Evaporative gas cooling and conditioning systems help protect your downstream equipment, enhance air pollution control performance, reduce gas volumes, and increase production capacity. Central to our systems are Turbotak atomizing nozzles, which introduce a controlled amount of finely atomized water into the hot gas stream to reduce and/or maintain gas temperature. The water evaporates, while absorbing heat from the gases, for free-flowing dust, zero liquid discharge, and minimal or no wall buildup.
Sierra specializes in accurate mass flow measurement and/or control of Nitorgen gas. One of the most commonly measured gases, applications are found across numerous industries ranging from general process control to scientific research and development.
Biodegradation tests involve testing samples in response to various parameters: dilution, nutrient addition, pH, temperature, and others. The pattern of oxygen uptake in aerobic tests; nitrogen gas production in anoxic denitrification tests; methane production in methanogenic tests; hydrogen production during glycolysis; and carbon dioxide production during fermentation reactions gives a measure of the rate and extent of biodegradation of the organic constituents of the test sample.
Monitoring stack emissions is a fundamental requirement for most industrial processes. Our gas analysers, dust monitors and flow monitors are designed for a wide range of applications and can operate as a fully integrated system or as stand alone instruments.
As exhaust emissions from engine tailpipe have been decreasing in recent years through development of engines and exhaust after-treatment systems, non-exhaust emissions have become a major contributor to total particle emissions from vehicles. Dekati provides complete measurement solutions for brake wear and blow-by gas emission measurements and we can cover the complete particle size using only one measurement method – 6 nm – 10 µm with one measurement method.
Precision high pressure mass flow control is very difficult. Sierra has met this challenge with a patented high pressure mass flow controller design that offers impermeable elastomers with very little leakby.
Sierra has a complete line of fuel flow measurement instrumentation. Our ultrasonic and vortex flow meters are an ideal choice for accurate filling, transport and usage fuel flow applications found in general industry. Through our Automotive Test Division, we also manufacture a line of ultra-high accuracy vehicle consumption measurement system called FuelTrak.
For over 40 years Sierra has advanced our flow technology to offer customers around the globe the most cutting-edge thermal technology on the market.

A modern production method of nitric acid may lead to a generation of several different gaseous emission components, such as nitrogen oxides (NOx), ammonia NH3 and nitrous oxide N2O. Nitrogen monoxide is an intermediate gaseous product in the manufacturing of nitric acid HNO3. NO is formed in a catalytic reaction between ammonia and molecular oxygen O2. But undesirable side reactions may result in a formation of nitrogen dioxide NO2 and nitrous oxide N2O.
Cargo containers and wooden packing materials are fumigated to control the spread of pests and micro-organisms. However, fumigant gases are toxic and present a danger to human health even at low concentrations. Additionally, products shipped in containers may release VOCs from the solvents, coatings and glues used in manufacturing processes, and the concentrations of these vapors may be significant in the confined space of the container. Gas measurements are required to protect the health of any workers involved...
Advanced optics manufacturing is now requiring much cleaner processing environments than were necessary in the past. Smaller device structures, use of shorter wavelengths, and higher laser power densities are all factors that make advanced components more susceptible to damage from contamination. Particle Measuring Systems can provide you with the tools to determine how clean your environment is.
According to US EPA IO - 3.3 standard method of heavy metals, flue gas heavy metals analyzer uses XRF nondestructive testing technology and flue gas automatic enrichment technology to realize the accurate measurement of flue gas heavy metals such as waste incineration plants, cement plants, thermal power plants, etc.
We get it. All fingers point at you if productivity slips because of incorrect steam flow calculation. All you really want are flow instruments that are easy to install and provide highly accurate data. And work 24/7 with no downtime. Meet the original. In the ’90s, Sierra was the first multivariable mass vortex flow meter supplier in the world when we pioneered InnovaMass. Vortex volumetric flow and multivariable mass flow meters are the ideal technology for calculating steam flow. Our InnovaMass vortex...
