Process Description
"Ammonia, liquid, anhydrous" is an inorganic substance. Under IUPAC nomenclature, it is known as "azane", with the molecular formula: NH3. It is a gas under normal temperature and pressure conditions, possessing a distinct pungent odor. It can be used in the following products: cosmetics and personal care products, heat transfer fluids, cleaning and washing products, and coating products. In industrial settings, this substance is used to manufacture products in the following industries: chemicals, textiles, leather or fur, pulp, paper and paper products, plastic products, and metal products.

Technology comment
The water-coal slurry obtained from processed raw coal reacts with pure oxygen produced by the air separation unit, generating synthetic gas that is then sent to the shift conversion unit where CO in the synthetic gas reacts with steam to convert into CO2 and H2. When the CO content in the shifted gas decreases to 0.5%--1%, the gas is cooled and enters the cold methanol washing section to remove most of the H2S, CO2, and H2O. Subsequently, it enters the liquid nitrogen washing unit for further purification, reducing the CO+CO2 content in the decarbonized gas to less than 15 ppm, and after separation, is compressed to 13 MPa by a compressor. 9 MPa, together with the circulating gas discharged from the circulating gas compressor, enters the ammonia synthesis process, where ammonia is produced under the action of a catalyst, followed by separation to obtain liquid ammonia product; unreacted circulating gas is sent back to the circulating gas compressor for further recycling.
