Coal Seam Gas

The Coal Seam Gas (CSG) process is a natural gas extraction process from coal seams buried in the ground. In order to release the gas, the coal seams are de-pressurized by releasing large volumes of water.

The water that is a by-product of the CSG production process often has difficult water chemistry, such as high silica and alkalinity. Given the remote environments, extreme conditions, strict environmental and health & safety regulations, as well as limitations on disposal options, treating this water in an effective, efficient and reliable way is critical.

IDE delivers efficient and modular solutions for the CSG industry, which reduce Capex and Opex. These are based on our decades of experience, and are flexible and adaptable to a wide variety of environments and situations. The high reliability of our units delivers highly cost-effective water treatment solutions.

IDE’s Solution for CSG

IDE’s expertise in both membrane and thermal technologies allows it to offer end-to-end solutions for produced water treatment, from water to Zero Liquid Discharge (ZLD) level. This includes all necessary pretreatment, UF, RO, Brine Concentrators and Brine Crystallizers.

Our modular and pre-fabricated solutions for both reverse osmosis and thermal solutions are easy to install, with minimal on-site set up, and are particularly suited for remote locations.

IDE is highly conscious of environmental and health and safety considerations, and our equipment is designed to reach the lowest energy consumption benchmark in the industry, as well as very low chemical consumption. Our unique horizontal configuration allows safer operation without any need to work at heights, thereby increasing safety and visibility.

IDE also has a proven track record in EPC, turnkey, O&M, BOT and other business and construction models, and can adapt to the client’s preferred delivery model.
