Desulfurization device for methyl tert-butyl ether

Abstract

The utility model discloses a desulfurization device for methyl tert-butyl ether. The device comprises a static mixer, a synthesis reactor and a distillation tower, the static mixer comprises a firstmixing part and a second mixing part, the first mixing part is provided with an accommodating cavity, a honeycomb-shaped liquid channel is formed in the accommodating cavity, the honeycomb-shaped liquid channel divides the accommodating cavity into a first accommodating cavity and a second accommodating cavity, the sidewall of the first accommodating cavity is provided with a first liquid inlet, the second accommodating cavity is connected with the second mixing part through a pipeline, a spoiler is arranged in the pipeline, and a plurality of mixing blades are arranged in the second mixing part. The design of the first mixing part and the second mixing part makes materials mixed uniformly, so subsequent work is facilitated.

Description

technical field [0001] The invention relates to equipment in the petrochemical field, in particular to a desulfurization device for methyl tert-butyl ether. Background technique [0002] At present, methyl tert-butyl ether is generally added to domestic gasoline in order to increase the octane number of gasoline. However, the new regulations on environmental protection require gasoline to meet the National IV or National V standard, that is, its sulfur content is less than 50mg / kg or 10mg / kg. At present, the main production process of methyl tert-butyl ether in China is the etherification and separation of mixed C4 and methanol in a catalytic distillation tower with cation exchange resin as a catalyst. MTBE products usually contain 50-200mg / kg of sulfides, and MTBE produced by some manufacturers sometimes contain up to 2000mg / kg of sulfides, so MTBE must be desulfurized to be able to As an ideal blending component, the desulfurization equipment in the prior art cannot comp...

AI Technical Summary

Problems solved by technology

MTBE products usually contain 50-200mg / kg of sulfides, and MTBE produced by some manufacturers sometimes contain up to 2000mg / kg of sulfides, so MTBE must be desulfurized to be able to As an ideal blending component, the desulfurization equipment in the prior art cannot completely remove the low-boiling component sulfide in the desulfurization ancient city. In addition, the desulfurization equipment in the prior art has a complicated structure and is inconvenient to operate, which greatly increases the desulfurization rate. cost, the present invention proposes a new solution to the above problems
