Abstract

The invention discloses hydrogen raw material production equipment and process for ammonia synthesis. The hydrogen raw material production equipment comprises a control device, a methanol water storage conveyer and at least three groups of methanol water-reforming hydrogen production modules, wherein the control device is electrically connected with the methanol water storage conveyer and each group of methanol water-reforming hydrogen production modules, so as to control the working states of the methanol water storage conveyer and the methanol water-reforming hydrogen production modules; hydrogen prepared by various methanol water-reforming hydrogen production modules is directly conveyed to an ammonia synthesis system through conveying pipelines; and the control device is used for controlling a proper number of methanol water-reforming hydrogen production modules to run according to the hydrogen raw material quantity demand information of the ammonia synthesis system. The hydrogen raw material production equipment is high in modularization; a single module is small in size and fast to start; the hydrogen can be immediately prepared without a hydrogen storage tank, and can be rapidly separated; and the hydrogen raw material production equipment is good in stability, high in intellectualization, sensitive in parameters control of hydrogen preparation temperature, gas flow and air pressure, high in safety and high in reliability.

Description

technical field

[0001] The invention relates to the technical field of ammonia synthesis industry, in particular to a hydrogen raw material production equipment and process for ammonia synthesis. Background technique

[0002] Ammonia is one of the most important basic chemical products, not only the main final product, but also an important intermediate. Synthetic ammonia is widely used in the production of chemical fertilizers, various ammonium salts, nitric acid, explosives, plastics, synthetic fibers, paints, photosensitive materials and other products. At present, China's annual output of synthetic ammonia is more than 50 million tons, accounting for about one-third of the world's output. The raw materials for the ammonia synthesis industry are nitrogen and hydrogen. Nitrogen is separated from the air. The two commonly used separation methods are liquefaction and fractional distillation. The boiling point of nitrogen in the air is lower than that of oxygen. First, the ...
