BHSGermany-based BHS-Sonthofen has produced five filter systems for use in natural gas production in southwest Iran, together with its Iranian sales partner Faris International
The new plants allow for the environmentally friendly and efficient circulation of raw materials.
About 120,000 barrels of liquid natural gas (LNG) per day is the planned capacity of a new gas refinery in Iran that is currently being constructed under the project name ‘Bid Boland II.’
In the future, natural gas will be extracted from the earth and separated from contaminants in the first process step. BHS-Sonthofen supplied expertise in the clarifying filtration of process liquids as a specialist in filtration technology.
BHS optimises ‘amine sweetening’ process
Natural gas is extracted from the ground as a mixture of gases, and some of its components are not suitable for further processing. These include sour gases such as hydrogen sulfide and carbon dioxide. These contaminants can be washed out using the ‘amine sweetening’ process, an internationally licensed process developed by the French license provider PROSERNAT.
BHS-Sonthofen has developed a complete system that comprises several components for the subsequent process steps to remove hydrocarbons and dissolved contaminants. The end result is an efficient circulation process that ensures optimal resource usage.
The overall turnkey concept devised by BHS-Sonthofen consists of three process steps in total which include candle filter, carbon filter and the scrubber. These steps help in separating the amine solution from hydrocarbons and foreign particles that cause wear.
BHS filter system aims to ensure both increased efficiency and process reliability by separating the amine solution from hydrocarbons and foreign particles that cause wear. The company supplies the three filters and the precoating unit as a complete preinstalled one-point lifting unit.
“The filters are ready for immediate use after connecting them to operating resources and feeding in product streams,” said BHS.
Commenting on the natural gas processing, Tim Ochel, project manager at BHS-Sonthofen, said, “System assembly is usually carried out in Germany entirely. The oil and gas industry has been benefiting from our turnkey filtration solutions for years.”
BHS-Sonthofen fully engineered and designed the five systems. The containers, steel constructions and piping were constructed by local suppliers with the support of Faris International. The company also provides technical solutions for mechanical process technology, concentrating primarily on mixing, crushing, recycling and filtration.
