How to put the atmospheric safety valve of the ethylene plant into operation
Just open the valve that cuts off the safety valve – what’s different about that compared to other methods?
The atmospheric safety valve for ethylene is the safety valve on the turbine condenser, not a regular safety valve.
Yes, how was it put into use when it started operation?
It’s not an ordinary safety valve; it’s an atmospheric safety valve for the turbine feedwater system
It is put into use when driving the compressor turbine to create a vacuum; the water from the outlet of the turbine condensate pump is used to feed the atmospheric safety valve, thereby establishing a water seal.

Once a vacuum is created, it can be put into use; open the pipeline from the outlet of the abdominal water pump to the atmospheric safety valve – if water flows out from the outlet of the atmospheric safety valve, then it’s ready for use
It can be put into normal use before starting up; the condensate is used to establish a liquid seal
After establishing a vacuum, it can be put into use. Open the water line from the outlet of the abdominal pump to the atmospheric safety valve; when water flows out from the outlet of the atmospheric safety valve, it is ready for use
