INSTALLATION FOR TREATMENT OF OIL CONTAINING HYDROGEN SULPHIDE Russian patent published in 2016 - IPC B01D19/00 

FIELD: oil industry.

SUBSTANCE: invention relates to apparatus for treatment of oil containing hydrogen sulphide and can be used in oil producing industry for preparation of oil containing hydrogen sulphide. Apparatus for treating oil containing hydrogen sulphide includes a supply pipeline of oil containing hydrogen sulphide, separators of first and second separation stage with gas discharge gas pipelines, oil dehydration and desalination unit consisting of oil heater, settlers of stages of dehydration and desalination of oil with pipeline discharging settled water, pipeline of fresh water, gas line to feed desorbing gas into oil separator end separation stage with gas discharge pipeline, unit of chemical neutralisation. Apparatus further includes a water ring pump with its input connected with feed pipe of fresh water and gas discharge pipeline with separator end of separation stage, and a gas and water separator whose input is connected to output of water ring pump. Lower part of gas and water separator is connected by a pipe to oil pipeline before settling tanks for oil desalination stage, and its top with pipeline for discharging gas from separator of second separation stage.

EFFECT: high quality of commercial oil and gas and degree of purification from hydrogen sulphide and carbon dioxide, low power consumption, possibility of implementation on active facilities for treatment of oil containing hydrogen sulphide.
