Dehydration Unit (DHU) Project
In natural gas systems, removing water vapor reduces pipeline corrosion and eliminates line blockage caused by hydrate formation. The water dewpoint needs to be below the lowest pipeline temperature to prevent free-water formation. We have experience in every facet of gas processing. This enables us to deliver a complete integrated solution from the wellhead to the pipeline – including field construction/installation, operator training, and full life-cycle support.
The most widely-used method for industrial dehydration of Natural Gas is absorption. Absorption is usually performed using triethyleneglycol sorbent (TEG). Absorption proceeds at low Natural Gas Dehydration temperatures and the absorbed water is boiled out from TEG during regeneration in a reboiler at high temperatures. We have experience with dehydration systems including ethylene glycol and tri-ethylene glycol dehydration, as well as physical adsorption via molecular sieve dehydration. Dehydration systems remove entrained water to avoid liquid drop out and bring gas stream to customers required specification.
Our network of experts provides a wide range of services, including:
- conceptual design, project execution
- precommissioning and commissioning
- operations, remote monitoring and technical support
