Abstract
In order to overcome the problems that because the oil temperature is too low before decolorizing, the oil color is too deep, thus the production process is not continuous in the prior art, the invention provides a new treatment method before decolorizing by making full use of the existing equipment and pipelines and improving a decolorizing pipeline. The treatment method comprises the steps of: enabling crude oil to pass through a heater for heating, then premixing, enabling the pre-mixed crude oil to enter a decolorizing tower for decolorizing, enabling a part of the decolorized crude oil to enter a condenser for condensing and collecting the crude oil, and enabling the other part of the decolorized crude oil to enter a circulating pipeline for decolorizing again, wherein before the crude oil is decolorized, the oil in the circulating pipeline is conveyed to the heater to be heated for a period of time. By the treatment method, the oil temperature reaches a normal level before decolorizing, thereby maintaining continuous production.

Summary of the invention
The present invention is excessively low for oil temperature before overcoming the decolouring that exists in the prior art, make the oil colours pool excessively dark, cause the problem that production process can not be continuous, by taking full advantage of existing installation, pipeline, the decolouring pipeline is improved, propose a kind of new front treatment process of decolouring, make the front oil temperature of decolouring reach normal level, keep producing continuously.
The present invention adopts following method to realize:
A kind for the treatment of method before decolorizing in oil processing technique, comprise and carry out premix after crude oil is by heater heats, decolour through entering bleaching tower behind the premix, enter condenser condenses through the decolouring rear portion and collect crude oil, a part enters circulating line and again decolours, when wherein decolouring, first the grease in the circulating line is transported to well heater and heats operation for some time.
Above-mentioned treatment method before decolorizing in oil processing technique, wherein circulating line is connected with the device for cleaning pipeline piping that enters before the well heater, when decolouring, make first connecting tube open-minded, making crude oil in the circulating line enter well heater heats, after heating operation for some time, connecting tube is closed, enter bleaching process.
Above-mentioned treatment method before decolorizing in oil processing technique wherein adopts opening and closing of control ball valve control linkage pipeline.
Adopt method of the present invention, killing two birds with one stone has solved the bleached oil oil temperature and has crossed low heating, and two problems of dark freshening are crossed in the oil colours pool, have satisfied the requirement of decolouring continuous production processes.Each start bleached oil enters filter to fuel-displaced limpid need of filter 1 hour, and the decolouring color and luster is crossed and deeply can in time be returned premixing tank and add the carclazyte freshening that again decolours, and falls color and luster and makes it to reach processing requirement, has greatly improved production efficiency, reduced production cost, convenient and practical.
