INSTALLATION FOR REMOVAL AND NEUTRALISATION OF HYDROGEN SULPHIDE AND MERCAPTAN FROM OIL WELL PRODUCTS Russian patent published in 2009 - IPC C10G29/00 

FIELD: oil and gas industry.

SUBSTANCE: invention refers to preparing products of oil and gas condensate deposits and can be implemented particularly for removal of hydrogen suplhides and mercaptan contained in oil and gas condensate with their successive neutralisation. The invention refers to the installation for removal and neutralisation of hydrogen sulphide and mercaptan from products of oil wells and includes the following combined: a stilling collector, a de-pulsator, separators, a heated hydro-cyclone, a condenser, a refrigerator, a benzo-separator with mass-changing volume nozzle, suction pumps, a reservoir connected with a hydro-gate, a running from the reservoir line for output of oil products and also including a reagent supply line into the line between the hydro-cyclone and the reservoir and into the benzo-separator, and a buffer capacity for water withdrawal; the installation additionally contains a re-circulation line which runs at the section after product output from the reservoir where the said products is directed by means of re-cycle into the hydro-cyclone and to the line of reagent introduction; reagent is supplied at the section between the unit of final product record and re-cycle of product outgoing from the reservoir.

EFFECT: development of installation for efficient removal of hydrogen suplhides and mercaptan contained in oil and gas condensate with their successive neutralisation.
