Problem:
Water is a common impurity in natural gas that must be removed to meet pipeline specifications and prevent hydrate formation. (back to top)
Solution:
PRISM® membranes provide an attractive alternative to traditional glycol systems based on simple process designs, lower costs, and the other benefits listed below. These benefits become even more pronounced as the industry produces natural gas from very remote locations. (back to top)
Benefits:
-
Ideal for remote locations with limited utilities.
-
Flexibility to explore process flow sheets with various product gas compositions.
-
No moving parts means minimal maintenance costs.
-
No additional hazardous chemicals, like glycols, to cause environmental complications.
-
Lightweight and compact.
-
Easy to install and operate.

Advanced PRISM® Membranes for Natural Gas Dehydration (136 K, PDF) (back to top)
Examples:
This offshore membrane system for Shell Nigeria is designed to dry 5 MMSCFD of natural gas from an inlet dewpoint of 41°C to an outletdewpoint of 0°C at 38 barg. It was designed and built by Petreco, an Air Products PRISM Membranes licensed partner.
PRISM membrane system pictured below dries 3.2 MMSCFD of natural gas. Owner-operator in Italy has over three years of operating experience.
PRISM membrane system pictured below dries 7.5 MMSCFD of natural gas. Owner-operator in Holland has over one year of operating experience.
