METHOD OF PREPARING OF ASPHALTENE-RESIN-PARAFFIN SEDIMENT INHIBITOR Russian patent published in 1994 - IPC

Abstract RU 2011674 C1

FIELD: chemical technology. SUBSTANCE: method involves preliminary addition of water to nonionogenic surface-active substance following by mixing with aliphatic alcohol at the following mass ratio of components: nonionogenic surface-active substance : water : aliphatic alcohol = (2-10): (0.6-1.4): (17.4-8.6). Monoalkyl esters of polyethylene glycol on the basis of primary aliphatic alcohols of the general formula CnH2n+1O(C2H4O)mH, where n = 10-18, m = 8-10, are used as a source of nonionogenic surface-active substance. Prepared inhibitor shows high effectiveness for prevention of asphaltene-resin-paraffin deposits, deemulsifying effect, improved technological properties and enlarged range of using. EFFECT: enhanced quality of inhibitor. 3 tbl
