COMPOSITION FOR REMOVING ASPHALTENE-RESIN PARAFFIN DEPOSITS |
摘要 |
petroleum industry, more particularly removal of asphaltene-resin-paraffin deposits during petroleum production. SUBSTANCE: described is composition for removing asphaltene-resin-paraffin deposits with high content of solid paraffin comprising components which are useful both in summer and winter. Composition comprises hydrocarbon solvent and 0.5-3 wt % of addition agent. Addition agent is mixture of 98-99 wt % of nitrogen-containing ethylene oxide-propylene oxide block copolymer with molecular weight of 5000 of diproxamine-157 or by-product resulting from production of isopropyl-benzene-polyalkylbenzene resin with 1-2 wt % of polyglycols resulting from production waste of glycols or mixture of 0- 29 wt % of diproxamine 157, 70-90 wt % of polyalkylbenzene resin and 1-2 wt % of polyglycols. Addition agent for improving service properties in winter is used in the form of solution in alkylbenzene fraction at weight ratio of 1:1 wherein alkyl is isopropyl or ethyl or butyl. EFFECT: effective composition for asphaltene-resin-paraffin deposits with high content of paraffins. 2 cl, 8 tbl |
