Abstract
The invention relates to a chlorinated paraffin vacuum removal process and chlorinated paraffin vacuum removal equipment. The process comprises the following steps: spraying chlorinated paraffin crudes into a vacuum separator; separating hydrogen chloride gases from solution in a vacuum state; allowing separated liquid to enter a chlorinated paraffin intermediate tank through an intermediate pump; and collecting separated gases from the top of the tower and allowing the collected gases to enter a vacuum injector, a storage tank for hydrochloric acid and the vacuum injector circularly through a vacuum pump sequentially, and to be discharged from the storage tank for the hydrochloric acid. By utilizing the equipment to generate vacuum, the process has the advantages of saving equipment investment, avoiding blowing agents (nitrogen), reducing resource consumption, basically improving conventional refining process, solving the problems of time consumption and energy consumption and greatly improving the processing capacity of crudes under the condition of reducing the equipment investment.
Description
Technical field:
The present invention relates to the clorafin process for refining, particularly a kind of vacuum removal process of clorafin.
Background technology:
In recent years, domestic clorafin production technology had obtained fast development, and output accounts for 1/4 of world's aggregated capacity.Because productivity effect is better, each producer is all expanding the scale of production as possible.Most producers utilize the still formula to blow down technology, and length consuming time and treatment capacity are little, and blowing down the agent consumption is greatly the bottleneck that the restriction scale enlarges.
Existing clorafin process for refining: (single still blowing technology)
Thick clorafin is squeezed into refining kettle, after logical nitrogen blows down 1-2 hour at the bottom of the still, makees sample and analyzes and produce after qualified.
The shortcoming of existing flow process: existing technology nitrogen blow-off, length consuming time, the nitrogen consumption is big, and facility investment is big, causes the waste of resource.
Summary of the invention:
The purpose of this invention is to provide a kind of chlorinated paraffin vacuum removal process.
Another object of the present invention provides the equipment of this kind chlorinated paraffin vacuum removal process.
The technical scheme that the present invention takes is:
Chlorinated paraffin vacuum removal process, clorafin crude product spray is entered in the vacuum separation tower, under vacuum state, hydrogen chloride gas is separated from solution, liquid after the separation enters the clorafin tundish by line pump, the gas of separating enters vacuum ejector from the cat head extraction, enter hydrochloric acid tank then, enter vacuum ejector by the vacuum pump circulation again, produce from hydrochloric acid tank at last.
The vacuum tightness of described vacuum separation tower is 0.085, and vacuum tightness is 0.085 in the vacuum ejector, and it is 10%～15% (v/v) that hydrochloric acid tank produces concentration of hydrochloric acid.
According to Henry's law, under vacuum state, Gas Solubility reduces; Under the situation that does not change the clorafin solution temperature, produce vacuum by equipment, under vacuum state, hydrogen chloride gas is separated from solution, the gas of separating enters vacuum ejector from the cat head extraction, produces after absorbing by hydrochloric acid tank, vacuum pump circulation.
The equipment of chlorinated paraffin vacuum removal process, comprise the vacuum separation tower, vacuum separation tower lower end links to each other with the clorafin tundish by line pump, the upper end is connected with vacuum ejector by pipeline, one end of vacuum ejector directly links to each other with hydrochloric acid tank, and the other end communicates with hydrochloric acid tank by vacuum pump.
Described hydrochloric acid tank is connected with the finished acid jar.
Advantage of the present invention:
The present invention is the technology of the clorafin crude product being carried out refinement treatment, utilize equipment to produce vacuum, not only saved facility investment but also avoided the utilization of blowing agent (nitrogen), reduce resource consumption, fundamentally improved original process for refining, solve problem consuming time in the device, power consumption, under the situation that reduces facility investment, improved the treatment capacity of crude product greatly.
