摘要:

基于某纯碱企业的现场调研和台账数据,运用物质流分析(MFA)方法对纯碱生产过程的盐水工序、石灰石煅烧工序、碳酸化工序等主要环节中的资源、能源消耗和污染物排放量进行了计算分析。计算结果表明,每生产1 t纯碱消耗原盐1.6 t、石灰石1.2 t、焦炭0.1 t、电能200 kW·h、蒸汽热能12 000 MJ,产生废气1.4 t、废液10 t、废渣1.7 t。

关键词: 纯碱, 物质流分析, 能量流分析

Abstract:

Based on the On-site research and ledger data of a soda ash factory,the total energy consumption and pollutants discharge of the main process,including the salt water process,limestone calcination process and carbonation process etc.,in the production of soda ash were calculated and analyzed by analysis of material flow(MFA)method. The results showed that for 1 t of soda production,1.6 t of raw salt,1.2 t of limestone,0.1 t of coke,200 kW·h of power,12 000 MJ of steam heat en-ergy were consumed,and 1.4 t of waste gas,10 t of waste liquid and 1.7 t of waste residue were produced.

Key words: sodium carbonate, analysis of material flow, analysis of energy flow
