天然气脱硫气-肥-氯-碱多联产循环工艺

Recirculation process for multi-production of fertilizer-chlorine-sodium carbonate from the residues of natural gas desulfurization

根据原子经济观点提出以碳当量计入化学加工能耗后的有效原子利用率,能够更完整地描述过程的原子经济性。基于此提出从天然气脱硫再生酸气出发的气-肥-氯-碱多联产循环工艺,其有效原子利用率接近1,产品附加值增长超过156%。

From the viewpoint of atomic economy, the atom effective utilization, namely AUe, in which the consumed energy in the chemical process is accounted in the form of equivalent carbon amount, was proposed to scale the atom economy level of the process more precisely. Accordingly a recirculation process for multi-production of fertilizer-chlorine-sodium carbonate from the residuals of natural gas desulfurization was developed with the value of AUe close to 1.0 and the ratio of product added value exceeding 156%.
