A kind of equipment of producing dimethyl sulfate

Abstract

The invention relates to the field of chemical industry, and in particular discloses equipment for producing dimethyl sulfate. The equipment for producing dimethyl sulfate comprises an esterification reaction tower, a degassing tower and a rectifying tower, wherein a top feeding hole formed at the top of the esterification reaction is communicated with a liquid material source through a pipeline; an esterification reaction tower material outlet formed on the bottom of the esterification reaction tower is communicated with a degassing tower feeding hole formed at the middle part of the degassing tower; the top discharge hole formed at the top of the rectifying tower is communicated with a first storage tank located outside through a pipeline; a side surface discharge hole formed on the middle upper part of the rectifying tower is communicated with a second storage tank located outside; a degassing tower gas outlet formed at the top of the degassing tower is communicated with the absorption tower gas inlet of an absorption tower. The equipment for producing dimethyl sulfate has the beneficial effect that the whole production process realizes continuous production, the reaction is more sufficient, the capacity and the product quality are greatly improved, the operation is automatically controlled completely, and the production is safer and more efficient.

Description

(1) Technical field [0001] The invention relates to the field of chemical industry, in particular to a device for producing dimethyl sulfate. (2) Background technology [0002] Esterification and rectification are two units in the production of dimethyl sulfate, and they are also the two most common units in the chemical process. Since the production process of dimethyl sulfate was put into operation, up to now, domestic and international All production processes adopt separate and discontinuous operation processes. Separate and discontinuous production has disadvantages such as incomplete reaction, low reaction efficiency, poor product quality, low production capacity, high energy consumption, low safety and environmental protection factor, and high environmental protection pressure. Existing technology is far from meeting the production and development needs of modern enterprises, which seriously restricts the innovation and progress of enterprises. (3) Contents of the i...
