The proportion of ammonium sulfate outputthat is produced as byproduct is gettinghigher and higher owing to its costadvantage.Most ammonium sulfate in Chinais produced as byproduct in other sectorssuch as coking,caprolactam,sulfuric acidtail gas desulfurization,power plant desulfurizationand acrylonitrile.The cokingsector is the major source of ammoniumsulfate byproduct.China is the biggest cokeproducer in the world.Coke output in Chinahas increased rapidly in recent years,yielding345.02 million tons in 2009 and around1.47 million tons of ammonium sulfate,accountingfor 52% of the national total.An-
