Compressor Seal Leak-off Gas Recovery

Centrifugal compressors for synthesis gas with sealing arrangements may vent or recycle seal leakoff gases to fuel. It is possible to save energy by collecting seal leakage (by installing a casing around the seal) and recycling it to lower stages of compression, thereby saving the feedstock from being vented or degraded as fuel (FAI, 2013).

 In India, gas from seals of synthesis gas compressors is being used as fuel in boilers in one plant (FAI, 2013).
