On Aug 28th, 2021, Daqing Continental shale oil National grade demonstration area was unveiled, with some exploit devices of continental shale oil already ready for use.
In this project, the Snowman group offers a propane refrigeration unit, to cool associated gas of shale oil to -20℃, adopting the ancestor of screw compressor in the world - SRM Sweden open type compound two-stage screw compressor, the design of the compressor is by the highest standard of petrochemical industry, American Petroleum Institute API-619 standard specification.
R290 refrigeration unit
Taking consideration of the restriction of the working site, the R290 refrigeration unit will be used outdoors
Taking consideration of the restriction of the working site, the R290 refrigeration unit will be used outdoors, so Snowman configure air cooled condenser, which will play an important part in this refrigeration system.
In the device of the chemical industry, R290 has a series of advantages as a refrigerant, but also has its particularity, for example, inflammable and explosive, the lower standard boiling point.
requirement of design
If the leakage happens on the refrigeration pipe, will form ultra-low temperature for an instant, thus the refrigeration pipe will be embrittlement. So the requirement of design, manufacture, and inspection is high, for example, specified accessories, explosion proof, high sealing ability, and strict requirement of discharge on site.
In the China Refrigeration Exhibition 2019, the exhibit of the Snowman Group 'SRC-S-353 R290 compressor' acquired the innovative product title, Snowman group continuously develops the application market of natural environmental protection refrigerants.
