Embodiment Construction

[0034] The present invention will be further described below in conjunction with the accompanying drawings of the description.

[0035] The present invention provides a composite process for producing raw materials of ammonia, methanol and carbon monoxide, which adopts the following process steps: 1. the water gas produced by the water gas generator 1 is imported into the converter, and its volume percentage is composed as follows:

[0036] Composition %VOL

[0037] h 2 32.50~36.57

[0038] CO 47.37~51.52

[0039] CO 2 12.38~16.43

[0040] COS+H 2 S 0.77~1.93

[0041] N 2 0.24~0.61

[0042] CH 4 +Ar 0.11~0.23

[0043] 2. Carry out the methanol washing of the aforementioned water gas produced in the methanol washing tank 3 to remove impurities such as hydrogen sulfide and carbon dioxide therein;

[0044] ③ According to the requirements of the hydroxylation process, the one-way water gas washed w...

Abstract

The invention provides a compound process for preparing ammonium, methanol and carbon monoxide. The current processes for preparing ammonium, methanol and carbon monoxide are independent, which means large investment and waste of chemical raw material. The invention provides a compound process for preparing said three products, which is characterized by smaller investment and saved raw material.

Description

Technical field: [0001] The invention relates to a process for supplying chemical raw materials, in particular to a composite process for producing ammonia, methanol and carbon monoxide raw materials. Background technique [0002] In the ammonia synthesis process, the water gas produced by coal gasification contains about 50% carbon monoxide. Carbon monoxide is not only not a direct raw material for ammonia synthesis, but also has a poisonous effect on the ammonia synthesis catalyst. Therefore, the feed gas must be cleaned of carbon monoxide before being sent to the synthesis process. In the production process of methanol, the CO content should be controlled at about 24-25%. [0003] In the prior art, the various processes for producing ammonia, methanol and carbon monoxide are independent of each other, that is to say, production lines must be set up for the production of ammonia, methanol and carbon monoxide respectively. A lot of waste of raw materials. Contents of th...
