Cold Rolling Sheet Hydrogen Recovery Plant / Bell Type Furnace 200 Nm3/H

OPPORTUNITY

In ammonia production, hydrogen and nitrogen are reacted at high pressure to form ammonia. Since the conversion per pass is not 100%, the reactor is operated in loop mode. Ammonia is continuously condensed out of the loop and fresh synthesis gas is added. Because the synthesis gas contains small quantities of methane and argon, these impurities build up in the loop and must be continuously purged to prevent them from exceeding a certain concentration. Although this purge stream can be used to supplement reformer fuel gas, it contains valuable hydrogen which is lost from the ammonia synthesis loop.

Description:

Recovering hydrogen for recycling working.

Capacity: 100-3000 Nm3/h  

Application: Cold rolled sheets bell type furnace annealing  

A great saving on cost, especially the raw material liquid ammonia,methanol consumption 

Take one 100 Nm3/h hydrogen recoverying unit for example, per year you can save more than 200,000 USD
