C4 raw material rectification and decarbonization three-tower device

Abstract

The invention relates to the technical field of C4 raw material rectification and decarbonization three-tower devices, in particular to a C4 raw material rectification and decarbonization three-tower device. The device comprises a base, a water tank, a feeding pipe, a stirring assembly, fixing rods, a support, a discharging pipe, a screen, a charging pipe, a preheating box, a fixing frame, a heating assembly, a pipeline, a cooling box and a discharging pipe. After C4 raw materials are fed into the water tank through the feeding pipe, the stirring assembly is started. The multiple fixing rods are oppositely arranged on the two side walls in the water tank correspondingly. A plurality of stirring rods of the stirring assembly and the plurality of fixing rods are arranged in a staggered mode, so that cleaning of C4 raw materials can be enhanced. The cleaned raw materials are put into the preheating box to be preheated through the heating assembly, then the cleaned raw materials are injected into the cooling box to be cooled, the raw materials can be decarbonized, and therefore, the follow-up process can be carried out.

Description

technical field [0001] The invention relates to the technical field of three-tower equipment for rectification and decarburization of C4 raw materials, in particular to a three-tower device for rectification and decarburization of C4 raw materials. Background technique [0002] Isobutene is a very important petrochemical basic raw material. At present, the production methods of isobutene mainly include catalytic cracking, butane isomerization followed by dehydrogenation (or isobutane dehydrogenation), n-butene skeletal isomerization and tert-butanol dehydration, etc. craft. Among these methods for producing isobutene, n-butene skeletal isomerization technology has the advantages of cheap and easy-to-obtain raw materials and sufficient sources, and has become the most promising method for increasing the production of isoolefins. [0003] The C4 plant mainly uses C4 after etherification as raw material to produce isobutene, which is used in the production of downstream etheri...

Problems solved by technology

[0004] The object of the present invention is to provide a kind of C4 raw material rectifying decarburization three-tower device, aims to solve the need to wash it before the removal of its raw material in the four-raw material refined decarbonization three-tower device in the prior art, however If it cannot be cleaned, it will affect the subsequent removal effect of the raw material, thus failing to meet the technical problems of the subsequent process.
