Problem: Hydrogen sulfide often prohibits utilizing readily available natural gas to generate power and drive compressors at remote locations such as oil and gas production sites. Production companies are faced with making a choice between shutting in a well, frequent engine overhauls, or logistical challenges associated with routing other fuels to the site. (back to top) Solution: PRISM® membranes act as a natural gas scrubber and are an attractive alternative by purifying sour natural gas into sweet fuel gas with higher heating values. Fuel gas conditioning systems incorporating PRISM membranes provide oil and gas production companies with an economical solution to an otherwise often monumental problem. (back to top)  Benefits: Ideal for remote locations with limited utilities and sour natural gas. No moving parts means minimal maintenance costs. No additional hazardous chemicals, like amines, to cause environmental complications. Lightweight and compact. Easy to install and operate.

(back to top) Frequently Asked Questions: What kind of filtration is recommended when using PRISM membranes for natural gas conditioning? At least two coalescing filters should be used upstream of the PRISM membranes to remove bulk liquid and aerosol water. Upstream filtration must remove solids and liquids 0.01 micron and larger and remove 99.999% of oil aerosols. Do I have to use a heater in my system? We recommend a heater in order to get the best performance from the PRISM membrane as well as to keep the heavier hydrocarbon components of the feed stream in a vapor phase and prevent condensation in the membranes. Do I have to dry the gas before it enters the membrane? No. Air Products PRISM Membranes are capable of water vapor removal and will dry the gas as it flows through the separator. However, the membrane should be fed with gas that is free of liquid water. Liquid water will temporarily reduce the performance of the device. However, if liquid water does contact the membrane, it can be easily dried and performance returned to normal. Should I be concerned about the heavy hydrocarbons in my stream? Heavy hydrocarbons will foul the membrane materials if they condense inside the device. Although the membrane may not be chemically attacked, removal of the oily film is difficult. This can be avoided through use of proper filtration as well as heating the membrane. (back to top)
