What is the approximate nitrogen sealing volume of the unit?
Thread Content
Our nitrogen gauge shows a reading of 4 cubic feet per hour under normal conditions, as its range is 7000 cubic feet per hour (this range takes into account the amount of gas needed for sealing purposes). In the hydrogenation unit, only a few tanks require nitrogen sealing, so there is almost no loss of gas. As for the nitrogen sealing used in the machinery units, what is roughly the amount required in that case?
Nitrogen flow rate for the dry gas seal in our system: 20 Nm3/h for the pre-seal, and 1.0 Nm3/h for the main seal
The seal air consumption of the centrifugal compressor (12,500 M3/h unit) is 70 m3/h
We offer dry gas seals for screw compressors: approximately 17 NM3/h for the first stage and 22 NM3/h for the second stage. However, the outlet pressure is not high at 1.0 MPa, with a flow rate of 25,000 NM3/h
The circulating hydrogen compressor (140,000 Nm3/h) of the paraffin oil hydrogenation unit is equipped with a dry gas seal, with a nitrogen consumption of 30 m3/h.
