American oil and gas corporation ExxonMobil has developed cMIST technology that dehydrates natural gas by utilising a patented absorption system inside pipes.
This technology can substitute traditional dehydration tower technology and is effective for both onshore and offshore natural gas production operations.

ExxonMobil has tested this technology extensively in fields. cMIST effectively removes water vapour present during the production of natural gas.
Eliminating water vapour through the use of dehydration technology, typically achieved using large and expensive dehydration towers, cuts down corrosion and equipment interference aiding to ensure the safe and efficient transport of natural gas through the supply infrastructure and ultimately to consumers.
ExxonMobil upstream research company president Tom Schuessler said: “By leveraging our industry-leading experience with upstream applications, our researchers were able to create this advanced natural gas dehydration technology, which represents a step-change in operational efficiency and a significant reduction in footprint.”
The company claims that cMIST reduces the size, weight and cost of dehydration, which would have profound benefits on offshore activities.

By GlobalDataThis technology works on a proprietary droplet generator to break up conventional solvent into tiny droplets that disperses during gas flow. The process increases the surface area for absorption of water from the gas. It is followed by an inline separator that combines water-rich glycol droplets and moves them to the outside wall of the pipe for effective complete separation from the natural gas.
The company has licensed cMIST technology to the Chemtech division of Sulzer. Chemtech division president Torsten Wintergerste said: “We are proud to have been selected as worldwide exclusive licensee of the cMIST technology, which includes our patented compact HiPer inline separator.
“We look forward to servicing the oil and gas industry with this unique technology, allowing for much needed reductions in capital expenditures for both greenfield projects and existing facilities seeking brownfield debottlenecking opportunities.
“cMIST technology complements the Sulzer line of compact multi-phase separation technologies and will maximise benefits available to oil and gas operating companies around the world.”
ExxonMobil’s Houston-based Upstream Research Company and ExxonMobil Research and Engineering division based in New Jersey employ more than 1,000 scientists who work on developing new technologies for oil and gas industry.
