摘要
简述了氨吸收制冷工艺及其特点,介绍了该工艺节能的技术特征,并对工艺进行了节能计算,通过氨吸收制冷工艺理论上可节省0.5MPa低压蒸汽53.4t/h,省却了冷却煤气余热的投资和运行费用。
The process and its energy saving features of refrigeration technology by ammonia absorption were introduced. The calculation shows that 534 t/h of 0.5 MPa low pressure steam can be saved theoretically. The investment and operation cost for cooling the waste heat of the gas were saved as well.
