FIELD: chemistry.
SUBSTANCE: invention relates to chemical additives applicable as inhibitors and absorbers. Disclosed are removal impurities and inhibiting hydrate multifunctional compositions used in applications related to production, transportation, storage and separation of crude oil and natural gas. Method of removing hydrogen sulphide impurities and preventing the formation of hydrates in the medium involves adding the multifunctional composition to the medium. Multifunctional composition contains an absorbent, a hydrate inhibitor and, optionally, an acid.
EFFECT: invention provides effective purification of hydrocarbon products from hydrogen sulphide with simultaneous prevention of hydrate formation, reduced corrosion of process equipment, improved environmental safety and reduced power consumption.
