China Petrochemical News Network reported recently that an ethylene spherical tank ice machine was put into use in an olefin area of Guangzhou Petrochemical Chemical, which not only increased the feed rate of the device, but also reduced the high energy consumption of the device by 1.
49 kg standard oil/ton
.
The original design of the ethylene spherical tank ice machine is only used during major repairs or when the device is out of order, and is not put into use during normal production
.
Due to the recent extreme high temperature weather in summer, the circulating water temperature is high, resulting in high temperature and pressure at the outlet of the propylene machine system of the cracking unit, which affects the feed load of the cracking unit
The First Chemical Industry Department quickly set up a research team to carry out technical research on this problem
.
After many discussions, analysis and research, it was decided to use the ice machine for the ethylene spherical tank.
After the ice machine is put into use, the average gas-phase ethylene can be recovered per hour of 530 kg, the propylene tower turbine condensate volume has dropped from 75.
9 tons/hour to 74.
6 tons/hour, and the propylene turbine vacuum degree has dropped from -63.
9 kPa to- 67.
7 kPa
.
The stable operation of the ethylene tank ice machine not only alleviates the problem that restricts the safe and stable operation of the device, but also reduces the amount of steam and realizes energy saving and consumption reduction
