摘要：

Recycle hydrogen compressor group is the core equipment of heavy coker gas oil hydrotreater unit of refinery. This compressor adopts tandem structure with intermediate labyrinth seal as its dry gas seal type. The compressor dry gas seal has officially been put into operation for six months, it damaged twice and caused the device to unplanned shutdown, seriously affected the long term operation of the device. During research and analysis on the seal of the unit, a series of problems were found, such as gas anti-channeling, sealing gas with oil etc. After transformation on the sealed gas supply system, the compressor achieved the purpose of long term stable running.
