PETROLEUM COMPOSITION Russian patent published in 1997 - IPC

Abstract RU 2100409 C1

FIELD: petroleum processing industry; petroleum compositions containing depression-inducing additive intended to lower petroleum solidification temperature. SUBSTANCE: to crude petroleum having solid paraffins content up to 30% depression-inducing additive, namely, 1,2-polybutadiene is added in amount 0.002-0.05% based on total petroleum weight, 1,2-polybutadiene has molecular weight 800-40 000, number of 1,2-units in it being 20-80%. EFFECT: useful to prevent petroleum solidification caused by freezing and low temperatures. 3 cl
