METHOD OF PURIFYING CRUDE OIL TO REMOVE HYDROGEN SULFIDE AND MERCAPTANS WITH ABSORBENT SOLUTIONS

FIELD: crude oil treatment. ^ SUBSTANCE: to remove hydrogen sulfide and mercaptans, 3-30% solution of urotropin in technical-grade formalin or in formalin/aqueous ammonia is added to crude material in amounts corresponding to 0.8-3.5 mole formaldehyde and 0.009-0.3 mole urotropin per 1 mole hydrogen...

Zusammenfassung:	FIELD: crude oil treatment. ^ SUBSTANCE: to remove hydrogen sulfide and mercaptans, 3-30% solution of urotropin in technical-grade formalin or in formalin/aqueous ammonia is added to crude material in amounts corresponding to 0.8-3.5 mole formaldehyde and 0.009-0.3 mole urotropin per 1 mole hydrogen sulfide and mercaptan sulfur. Reaction is carried out at 15 to 70°C. Method is applicable for oil and gas production and petroleum processing industries. ^ EFFECT: reduced consumption of reagents at high degree of purification of raw material. ^ 5 cl, 3 tbl
