METHOD TO SEPARATE PAINTED BODIES AND/OR ASPHALTENE ADMIXTURES FROM HYDROCARBON MIXES

摘要

FIELD: process engineering. ^ SUBSTANCE: proposed method comprises separating painted bodies and/or asphaltene admixtures from the mix of hydrocarbons containing at least 90 % by weight of hydrocarbons with the help of membrane. Said membrane has initial stock feed side and permeate discharge side. Said method comprises also withdrawing hydrocarbon permeates at said discharge side. Said permeates have reduced content of painted bodies and/or asphaltene admixtures. Note here that aforesaid membrane is arranged in spirally coiled membrane module. ^ EFFECT: continuous operation without notable interruption of initial stock or permeate flows. ^ 15 cl, 2 ex, 1 tbl, 5 dwg
