中石化巴陵石化烯烃事业部对凝结水系统实行优化改造后,每小时增加回收凝结水40吨以上,火炬蒸汽消耗减少2吨以上,余热锅炉除氧器加热蒸汽每月减少300吨。通过梯级换热,充分利用了凝结水低温热。这一优化改造产生的年度经济效益超过910万元。该事业部炼油装置建成投产已有15年,装置凝结水水质已不够稳定,不合格时只能被排入污水系统,造成能源浪费并增加污水排放。该事业部4套装置每小时产生的凝结水达82吨,因缺乏回收
After optimizing the condensate system, Sinopec Baling Petrochemical Olefins Department will increase the recovery of condensed water by more than 40 tons per hour, reduce the torch steam consumption by 2 tons and reduce the heat steam of steam boiler by 300 tons per month. Through the cascade heat transfer, make full use of the condensate low temperature heat. The annual economic benefits from this optimization and improvement exceed 9.1 million yuan. The refining unit has been put into operation for 15 years. The condensate water quality of the plant has not been stable enough. When it fails, it can only be discharged into the sewage system, resulting in the waste of energy and increasing the discharge of sewage. The Division 4 sets of devices produce 82 tons of condensed water per hour, due to lack of recovery
