New technologies for ammonia synthesis
Thread Content
The main technical upgrades are in gas generation and water treatment. New process is needed
Powder coal gasification will gradually replace slurry coal gasification.
Gasification is carried out using a Texaco or counter-flow four-nozzle gasifier, or a pulverized coal gasification process; shift reaction is performed via sulfur-resistant shift reaction; and purification is achieved through low-temperature methanol washing combined with liquid nitrogen washing.
Depending on the type of coal, gasification is generally carried out using the Texaco or pulverized coal gasification processes; shift reaction is performed using sulfur-resistant shift reactors, while purification is achieved through low-temperature methanol washing followed by liquid nitrogen washing. For synthesis, the 150-kilogram Cassali technology is employed. Reverse osmosis technology is widely used for water treatment.
