Subtract a ray of oil treatment system

The utility model provides a subtract a ray of oil treatment system, includes resorption agent pump, cooler, resorption tower and fractionating tower, wherein, resorption agent pump cools off a ray ofoil that subtracts that an underpressure distillation of underpressure distillation tower distils off that the mouth distils off in sending into the cooler, and then the mixed resorption agent inputtube of rethread is sent into in the resorption tower as liquid hydrocarbon component and vapour oil component in the resorption agent absorption dry gas, discharges through the resorption agent discharge pipe on the resorption tower at last and distillates fractionally in the fractionating tower to obtain diesel oil and wax oil. The utility model discloses a to subtract a ray of oil and be liquidhydrocarbon component and vapour oil component in resorption tower internal absorption dry gas is sent into to the absorbent with the mixed succeeding crop of diesel oil, then obtain qualified dieseloil and wax oil component t
