We have two Fuel Maker FMQ-8-36 units fed from LNG boil-off and we have experienced a high frequency of compressor failures (seized compressors) at less than 2500 hours run time, 1500 hours sooner than expected.
Does anyone have experience running a Fuel Maker off LNG feedstock?
The gas is warmed (ambient vaporizer) and odorized and regulated to 1.25 PSIG before it hits the FM units. We also have an inlet filter. I am certain it is not a temperature issue, the vaporizer is oversized and the gas temp is within 5 degrees of ambient after many hours of running. I'm thinking that the gas is so dry that we are getting premature wear on the cylinders.
I want to try oil injecting but this is challenging at low pressure and low flow. I may just replace the filter element with an oil saturated element from a different facility and hope the gas picks up some molecules on its way through the element. Adding a drip injector is another consideration.
Anyone have advice or experience they can share?
Thanks
