石油二厂化工车间原有4AN-15氨压缩机二台,切换使用。每台标准制冷量为15万千卡/时,配套电机为75千瓦。用液氨冷却生产装置的冷冻液,以满足工艺所要求的操作温度。1979年以来,化工车间自己动手设计了20万千卡/时的氨吸收制冷装置,其主要目的是充分利用装置多余的乏汽(表压2.5公斤/厘米~2)作为制冷的动力,以达到节电的目的,并为全厂进一步应用 Oil Plant two chemical plant original 4AN-15 ammonia compressor two, switching use. Each standard cooling capacity of 150,000 kcal / hour, supporting the motor is 75 kilowatts. Liquid ammonia is used to cool the plant’s cryogen to meet the operating temperature required for the process. Since 1979, the chemical plant has designed its own 200 MW / Ammonia absorption refrigeration unit. Its main purpose is to make full use of excess steam (gauge pressure 2.5 kg / cm ~ 2) as cooling power to achieve the The purpose of saving, and further application for the whole plant
