2002年安徽省高新技术企业2003年安徽省乡镇企业明星企业2001-2002年度安徽省重合同守信用企业合成氨厂全系统氨回收水平衡环保技术本公司独家开发的碳化原料气、合成放空气、氨罐弛放气、铜洗再生气(简称“四气”)氢回收技术,采用独特“W”形系列板式高效组合内件,利用原设备筒体改造氨回收塔,在保证各塔尾气指标合格的前提下,“四气”氨回收综合指标实现吨氨吨水,188 tt以上的浓氨水闭路循环全部回收,实现全系统水、氨平衡,环境治理彻底。改造后各塔氨回收指标如下。1、碳化氢回收综合塔:尾气中氨质量浓度≤0.1g/m~3,吨氨软水加入量500～700kg,回收氨水浓度80～110 tt,
2002 Anhui High-tech Enterprise 2003 Anhui Province Township Enterprise Star Enterprise 2001-2002 Anhui Province Contract and Trustworthy Enterprise Ammonia Plant Full System Ammonia Recovery Water Balance Environmental Protection Technology The Company developed the exclusive carbonated feed gas, synthetic air, ammonia Tank relaxation gas, copper washing regeneration gas (referred to as the “four gas”) hydrogen recovery technology, the use of unique “W ” series plate efficient combination of internal parts, the use of the original equipment cylinder transformation ammonia recovery tower, Under the premise of qualified tower exhaust gas indexes, the comprehensive index of ammonia recovery of “four gas” achieves tons of ammonia water, and the closed circulation of concentrated ammonia water above 188 tt is totally recovered, realizing the system-wide water and ammonia balance and thorough environmental control. After the transformation of the tower ammonia recovery indicators are as follows. 1, comprehensive recovery tower of hydrocarbons: exhaust gas ammonia concentration ≤ 0.1g / m ~ 3, tons of ammonia soft water added 500 ~ 700kg, recycled ammonia concentration of 80 ~ 110 tt,
