Mol sieve dehydration units provide an effective means to remove water vapor from a natural gas stream. Achieving cryogenic temperatures (-50°F and less) in natural gas processing requires the inlet gas to be free of water vapor. High water vapor can freeze at low temperature forming hydrates, and these hydrates can be problematic in a cryogenic process. Use of a mol sieve is an effective method to combat this issue.

The mol sieve design usually consists of a silicate compound containing very small pores of precise uniform size. The space between the silicate molecules act as a "trap" for the water vapor as it passes through the silicate.

Basic design consists of two or more identical mol sieve units. In a simple two-unit design, one unit operates in dehydration mode while the other in regeneration mode. Switching from dehydration to regeneration is done by use of automatic switching valves. As the dehydrated unit becomes saturated with water vapor, it is automatically switched to regeneration mode while the regeneration unit becomes active in dehydration mode.

Our mol sieve dehydration units are designed skid-mounted for simple installation and mobility purposes.
