Sequence for putting series dry gas seals into operation and taking them out of operation
Thread Content
When a dry gas seal is put into use, isolation gas is definitely used first, and it is also the last to be shut down! Secondly, it relates to the sequence in which the primary and secondary sealing gases are activated and deactivated. Could anyone explain the rationale behind this? We would appreciate any help you can provide; thank you

The commissioning of our dry gas system is a bit different from what you mentioned; we first put into use the main sealing gas and the pre-feed gas, and then the isolation gas. The reason for this order is determined by the functions of each type of gas, and the shutdown of the isolation gas is decided based on the shutdown of the lubricating oil
