Bill Phelps, Senior Business Manager, on length of membrane life.
“I always tell my customers that it depends on the quality of the gas that they’re feeding to the membrane. We expect the membrane to last ten to fifteen years, but that’s based on the fact that they’re maintaining their compressor, maintaining filter replacements, and maintaining pretreatments to the membrane. Our product can tolerate hydrocarbon vapors, but one thing that will kill the membrane is oil being deposited on the fibers. It’s very important to super heat the feed stream to keep any hydrocarbons in the vapor stage. That influences the length of the membrane life.”
