The Study Of The Producion Process Improvement To Ammonia By Methanol Release Gas

Ammonia is an important chemical raw materials,the basis of this ammonia production in article is used the gas of deflated in the methanol production,from hebei xu Yang coking co.,LTD.,the methanol plant of phase I and ii(100000 tons/year methanol)get gas of deflated after deducting self-used part,the rest of the enterprisesin methanol and all of methanol gas of deflated from three or four phase methanol device(150000 tons/year)is mergered.Ammonia construction scale is based on methanol gas of deflated total volume,at the same time,combining with the national industrial policy factors such as comprehensive consideration,ammonia plant construction scale of 100000 tons/year.Ammonia plant of our factory is domestic first set of methanol gas of deflated ammonia plant,in the process of operation,production process optimization and equipment modification,become the focus of our research.This topic through the comparison and analysis of energy consumption in ammonia production stages of the psa hydrogen making process control optimization.Combination of device technical transformation,realize the energy saving,consumption reduction,increasing the triple effect.With psa hydrogen production process control optimization,optimization of the psa hydrogen production technology parameters.The results showed that the hydrogen pressure swing adsorption(psa)has effect on device of consumption and income.After completion of ammonia spherical tank recovery reconstruction,it is safe of production and stable operation and increases the income 1.5 million yuan,and reduces the environmental pressure.After modification to the Circulating water in ? workshop series of methanol,it reduces the amount of scale inhibitor,bactericide,at the same time reduces the electricity and water,saves money 509000 yuan.After technological upgrading of Desulfurization tower,it increases 1.5 ~ 1.8 times of production capacity,there is no blocking phenomenon,it makes the equipment running smoothly.It can reduce the compressor power consumption,save electricity about more than 800 thousand yuan.
