摘要
通过完成浓氨水循环洗涤－结晶－吸附相串联与氨水精馏法制液氨工艺的联合应用，提高了由含硫含氨污水回收液氨的质量，使液氨纯度在９９．６％ 以上，保证氨气中总硫含量在１０ ｍ ｇ／ｍ ３ 以下。找到了先进、合理的含硫污水汽提氨精制工艺，年创效益１１２．４
After completion of the washing/crystallization/adsorption processing in series and the application of liquid ammonia prepared by distilling the ammonia spirit, the purity of liquid ammonia was enabled to be higher than 99.6% and the sulfur content in ammonia was less than 10 mg/m 3. Which indicated that the said process is advanced and reasonable. An annual profit of 112.4 million yuan was obtained.
