Abstract
The invention provides a high-efficiency emulsion splitter used in the oily industrial sewage disposal of a delayed coking effluent oil treatment system of an oil refinery, which is prepared by evenly mixing 20-30% of C12 fatty alcohol polyoxyethylene ether, 30-40% of polyethylene polyamine polyoxypropylene polyoxyethylene ether and 40-50% of sec-octyl phenol polyoxyethylene ether according to the weight percentage in a way of mechanical mixing. The high-efficiency emulsion has good oil removing effect on treating industrial sewage of delayed coking of an oil refinery, can the oil removing rate reaches over 85%, so that the emission of an oil refining device can reach the standard.
Description
Technical field
The invention belongs to the industrial sewage treatment technology field, relate to a kind of auxiliary chemicals emulsion splitter, relating in particular to a kind of is the emulsion splitter of main raw material with secondary octyl phenol polyethenoxy ethers, is mainly used in the processing of refinery tar from delayed coking treatment system oil-containing industrial sewage.
Background technology
In petroleum refining process, oleaginousness is too high and make water quality be difficult to reach the situation of emission standard in the normal industrial sewage that the discharging of oil refining processing unit (plant) occurs.Along with the increase of refinery heavy crude proportion, acid value for crude oil also presents ascendant trend.The increase of acid number makes that crude oil oil-water emulsion phenomenon in the refining course of processing is serious day by day, and the oil content of wastewater of discharging is too high, has exceeded refinery's device sewage discharge index.This not only can cause environmental pollution, and causes a large amount of oil product losses.In order to solve the too high problem of oleaginousness in the oil refining enterprise industrial sewage, the general employing of refinery will be refined oil the industrial sewage that produces in the processing unit (plant) and be utilized de-oiling agent to carry out de-oiling to handle, and make it reach discharging again after PetroChina Company Limited.'s emission standard.
The emulsion splitter of present domestic use mainly contains DR-951 emulsion splitter, BS-108 emulsion splitter, DE-0712 emulsion splitter, but these emulsion splitters are because de-oiling rate not high enough (general de-oiling rate is about 60%) can not satisfy the requirement of production equipment industrial sewage discharging.
