CARBON SULPHIDE-CONTAINING OIL TREATMENT PLANT Russian patent published in 2011 - IPC B01D19/00 C10G29/00 

FIELD: process engineering.

SUBSTANCE: invention relates to oil treatment plants and may be used in oil extracting industry. Proposed plant comprises separation units, preliminary and deep oil dehydration unit, oil desalination unit, unit of chemical neutralisation of carbon sulphide and light mercaptans with pressure pipeline to transfer proportioned reagent from reception and storage unit into oil pipeline, unit for commercial oil collection and storage, edge water collection and storage unit communicated via pipeline with preliminary oil dewatering unit. Unit of chemical neutralisation of carbon sulphide incorporates additionally flow metres and settler with pressure pipeline outlet arranged there between in oil pipeline. Flow metre is functionally connected with unit of chemical neutralisation of carbon sulphide to stabilise flow rates of reagent and oil, while additional settler is communicated via drain pipeline with preliminary oil dehydration unit.

EFFECT: higher efficiency of oil treatment at minimum costs.
