Only China produces industrial amounts of urea from coal. Producing urea from coal is expensive. China is the world''s largest producer of urea (38% of global supply) despite being its principal highcost producer (Figure 1). We suspect that China''s urea production is at risk to increasing amounts of cheap global natural gas (urea) from the ...

Figure 1 shows a simplified block flow diagram (BFD) of a methanol (MeOH) plant based on coal feedstock. Syngas from the gasifier is cooled by generating high pressure (HP) steam in the high temperature (HT) gas cooling system before being water quenched and scrubbed to remove fine particulates. The scrubbed syngas then goes through a sour water gas shift (WGS) to adjust the H2to .

Urea was first produced industrially by the hydration of calcium cyanamide but the easy availability of ammonia led to the development of ammonia/carbon dioxide technology. This is a two step process where the ammonia and carbon dioxide react to form ammonium carbamate which is then dehydrated to urea.
