Analysis and Research on the Impact of Coke Oven Gas Components on the Production and Consumption of Synthetic Ammonia and Urea
In view of the problem of stable coke oven gas supply and low urea and liquid ammonia production in Lingshi Middling Coal Chemical Industry,by comparing the gas analysis and consumption from 2018 to 2019,it is concluded that the change of total carbon and methane content in coke oven gas components is the main factor affecting the low urea production of synthetic ammonia.When the methane content decreases,the liquid ammonia production decreases and the ammonia gas consumption increases.When the total carbon decreases,the urea production decreases and the gas consumption per ton of urea increases.After adjusting the coal blending ratio through company maintenance,the ratio of liquid ammonia to urea production gradually decreased as the methane and total carbon content were increased.
