Compressor
Thread Content
I would like to ask what the functions of the primary seal gas, secondary seal gas, and isolation gas in a compressor are
Isolation gas is used to prevent oil and gas from the bearing housing from entering the seal. The primary sealing gas is filtered process gas; it is necessary to maintain a certain flow rate through the comb-tooth seal in order to prevent dirty process gas from reaching the seal. The secondary sealing gas is usually filtered nitrogen, which is used to carry any leaked process gas to the flare system, with the flow rate and pressure being used to determine the condition of the seal
