Cyclic hydrogen compressor
Thread Content
Is it necessary to supply nitrogen for the dry gas seal when the cyclic hydrogen compressor is undergoing a no-load test? Should the nitrogen for the dry gas seal be at a low level or at a slightly higher level at the packing outlet?
It is necessary to install a dry gas seal to prevent compressor oil from leaking into the process gas system. There should be a self-acting control valve; just activate it and it’s done.
A no-load test means operating it in accordance with the requirements for normal operation
A dry gas seal needs to be installed, in order to prevent lubricant from entering the seal before the lubricant is put into use； Furthermore, if it is level 2, one must first invest at level 1 before investing at level 2
Nitrogen needs to be supplied, including for the primary seal gas during the unit’s purging process (nitrogen is also required here); the secondary seal gas is also nitrogen. It is essential to supply the primary seal gas first, followed by the secondary seal gas. The pressure in the secondary seal chamber must not exceed that of the primary seal chamber. Isolation gas, which is nitrogen, needs to be supplied before the unit starts operating with oil. I hope this can help you.
It should be put into use. The function of nitrogen sealing for the recycle gas compressor is, first, to isolate the gas seal, and second, to cool down and create a gas film that provides lubrication.
