Problems solved by technology

[0002] The production of synthetic ammonia is a relatively mature technology. Various energy-saving technologies are more and more widely used in the production of synthetic ammonia. How to reduce the effective gas (mainly H 2 , CO, NH 3 Recycling and utilization of other gases) is a problem we must face. In the traditional synthetic ammonia production, there is recycling, but the investment in equipment is large, and some gases are incompletely recycled, resulting in waste.

Embodiment Construction

[0024] The method of the present invention will be described in detail below in conjunction with the embodiments and the accompanying drawings.

[0025] A method for recovering effective gas from synthetic ammonia, comprising a gas-making process of semi-water gas, a purification process such as decarburization, a refining process, and a synthesis process of semi-water gas such as the recovery of effective gas such as methanol and synthesis processes. The specific recovery process is as follows:

[0026] 1. Effective gas recovery in semi-water gas purification process.

[0027] 1.1 Effective gas recovery in semi-water gas decarbonization process, see figure 1

[0028] In the decarbonization flash tank 10, the decarburization flash vapor flashes H at 1.0-1.2MPa 2 (26.3%), CH 4 (3.1%), CO (2.6%), N 2 (12.6%), CO 2 (55.0%) and O 2 (0.4%), send the above gas to CO 2 Absorption tower 11 absorbs CO with decarbonization liquid 2 After, the unabsorbed H 2 、CH 4 , CO, N 2 , ...

Abstract

The invention discloses an available gas recovery method in ammonia synthesis process. The method can recovery available gas of semi-water gas decarburization process in the process of ammonia synthesis, decarburization flash steam is sent to a carbon dioxide absorption tower to absorb carbon dioxide, and the unabsorbed gas is sent to a compressor for recycling. The method can effectively recoverand reasonably use discharged available gas in the process of ammonia production, improves utilization ratio of energy, saves energy, and increases enterprise revenue.

Description

technical field [0001] The invention relates to an energy-saving technology in a synthesis ammonia process, in particular to a method for recovering effective gas from synthesis ammonia. Background technique [0002] The production of synthetic ammonia is a relatively mature technology. Various energy-saving technologies are more and more widely used in the production of synthetic ammonia. How to reduce the effective gas (mainly H 2 , CO, NH 3 Recycling and utilization of other gases) is a problem we must face. In the traditional synthetic ammonia production, there is recycling, but the investment in equipment is large, and some gases are incompletely recycled, resulting in waste. Comprehensive analysis and utilization. Contents of the invention [0003] In order to solve the above technical problems, the patent of the present invention provides a method for more effectively recovering various effective gases in the ammonia synthesis process. Due to the high oxygen cont...
