Abstract
A technology for removing colloid from a cracking-byproduct carbon ten material. The technology comprises that the mixed carbon ten material is fed into a colloid-removing tower (C-104); heavy components of the oil at the bottom of the tower are yielded through the bottom of the tower then is fed into a heavy-component oil tank (T-002A/B); gas at the top of the tower is fed into a return tank at the top of the tower (V-104) after passing through a condenser (E-109) at the top of the tower; light components of the oil in the return tank are yielded after passing through a reflux pump (P-108A/B) at the top of the tower. A part of the light components returns to the colloid-removing tower (C-104) as top reflux and the left as colloid-removed light component product is fed into a light component storage tank (T-008A/B). The technology employs a negative pressure structured packing tower, and through the control of parameters of negative pressure, feed temperature, a reflux ratio and temperature of the bottom of the tower, effectively controls a colloid content in the light components, thus usage requirements of blending gasoline and solvent are met.
Description
Technical field
The ten types of raw materials of carbon that the present invention relates to after processing technology field, the especially cracking of International Classification of Patents C10G oil cracking hydrocarbon oil, liquid hydrocarbon mixture take off the gelationus treating method.
Background technology
At present, it is to make raw material by the cracking raw gasline that ethene produces carbon ten products, removes through behind the one-stage hydrogenation; Staple is three benzol mixtures and carbon ten above components, and leading indicator is following: outward appearance is yellow, density about 0.90; About 45 ℃ of flash-points, condensation point ℃, boiling range 120-230 ℃.Cracking by-product carbon ten raw materials are most of to be used as oil fuel; After having only a few part by simple separation; Use as mixed oil; But gum level is higher in the light constituent oil after the simple separation, makees solvent and still does the performance that mixed oil uses all influences its major product, has reduced its utility value.Related application is rare open; For example; The method of 200810012200.3 1 kinds of producing aromatic hydrocarbon solvent oil by using pyrolysis gasoline of application number is a raw material with a certain cut of pyrolysis gasoline or pyrolysis gasoline, adopts the pre-treatment-matter of coming unstuck-hydrorefined combination process to produce aromatic hydrocarbon solvent oil.After pyrolysis gasoline removes unstable compounds such as diolefine and colloid through the pre-treatment and the matter unit that comes unstuck, directly carry out unifining and produce aromatic hydrocarbon solvent oil, owing to only adopt the one-stage hydrogenation process, plant construction investment and process cost obviously reduce.This type of correlation technique matter of coming unstuck belongs to important step, and the matter technical scheme of coming unstuck of the prior art is less, and uses and have difficulties.
Summary of the invention
The purpose of this invention is to provide and a kind ofly can effectively take off the gelationus method by product carbon ten after the cracking.
Goal of the invention of the present invention realizes through following technical measures: mix carbon ten and send into the matter tower (C-104) that comes unstuck, heavy constituent oil tank (T-002A/B) is sent in the extraction at the bottom of tower of heavy constituent oil at the bottom of the tower; The cat head gas phase gets into return tank of top of the tower (V-104) behind overhead condenser (E-109); Light constituent is through trim the top of column pump (P-108A/B) extraction in the return tank; A part turns back to the matter tower (C-104) that comes unstuck as trim the top of column, and a part is sent into light constituent storage tank (T-008A/B) as having taken off gelationus light constituent product.
The invention has the beneficial effects as follows: adopt the negative pressure regular packed tower,, effectively control the gum level in the light constituent, reach the requirement that blended gasoline and solvent use through negative pressure, feeding temperature, reflux ratio and the control of column bottom temperature parameter.
