塔西南勘探开发公司塔西南化肥厂拥有以天然气为原料的20万t/a合成氨和34万t/a尿素装置,自开车以来一直存在合成氨燃料气消耗较高的问题。为此对燃料系统进行了操作优化和节能改造。通过优化和改造,燃料气消耗已明显降低。同时,在弛放气入一段炉前加换热器技术是我厂的创新技术,属国内同类行业首次使用,该技术的实施不仅提高了弛放气的温度,增加混和燃料气的显热,达到降低燃料气消耗的问题,同时为同行业解决类似问题提供新的思路与实践经验。
The tower southwest exploration and development company tower southwest fertilizer plant has natural gas as raw material of 200000 t / a synthetic ammonia and 340000 t / a urea plant, since the car has been the problem of consumption of high ammonia fuel gas. To this end, the fuel system has been optimized for operation and energy-saving retrofit. Fuel gas consumption has been significantly reduced through optimization and retrofit. At the same time, it is the first time for similar industries in our country to apply heat exchanger technology to relax gas into a furnace. The implementation of this technology not only increases the temperature of the purge gas and increases the sensible heat of the mixed fuel gas, Achieve the problem of reducing fuel gas consumption, and provide new ideas and practical experiences for solving similar problems in the same industry.
