摘要：NOVELTY - Desulfurization deacidifying alkylated product comprises: taking liquid containing alkylated product, sulfate and sulfuric acid, flowing into acid washing separation tank (1), separating, entering into acid washing silk screen filler (2), fully contacting sulfuric acid and sulfate, and generating separation;#dissolving, exceeding sulfuric acid as heavy phase, placing into acid washing separation tank, sending to pickling sedimentation tank or alkylated reactor, entering alkylated product into acid separation tank and separating screen filler (3), and separating. USE - Method for desulfurization deacidifying alkylated product (claimed). DETAILED DESCRIPTION - Desulfurization deacidifying alkylated product comprises: (A) taking liquid containing alkylated product, sulfate and sulfuric acid, flowing into acid washing separation tank (1), separating, entering into acid washing silk screen filler (2), fully contacting sulfuric acid and sulfate, and generating separation; (B) dissolving, exceeding 50% sulfuric acid as heavy phase, placing into acid washing separation tank, sending to pickling sedimentation tank or alkylated reactor or discharging, entering alkylated product as light phase into acid separation tank and separating screen filler (3), and separating to obtain alkylated product containing 0.01-1.0% sulfuric acid; (C) separating sulfuric acid into acid washing separation tank bottom, and sending into acid hydrocarbon separation section having single grade or multistage acid hydrocarbon separation device for acid hydrocarbon separation; and (D) preparing alkylated product containing 0.01-1.0% sulfuric acid, coarse separating and fine separating, entering into acid sedimentation tank or alkylated reactor or discharging, sending into absorbing device, absorbing, and removing sulfuric acid and sulfate. An INDEPENDENT CLAIM is included for preparation of desulfurization deacidifying device. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic diagram of desulfurization deacidifying device (Drawing includes non-English language text). Acid washing separation tank (1) Acid washing silk screen filler (2) Separating screen filler (3)
