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, 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.

Utilizing Available Coldness from Liquefied Natural Gas LNG Regasification Process for Seawater Desalination
In this article a case study was considered, in which an LNG regasification plant can supply 1750 ton/hr of water-glycol solution at -15°C to be utilized for seawater desalination. The main challenge in this evaluation is being able to provide a desalination solution able to compete with the commonly used RO plants.

Three Pressure Retarded Osmosis PRO Processes
Pressure retarded osmosis (PRO) can be implemented on a number of water types, using different technologies and achieving various power outcomes. This paper presents the three most practical options.
Implementation of Build Operate Transfer Schemes: Obstacles and Solutions
This paper focuses on these cases, addressing the main causes of the failure of suggested/initiated BOT scheme offerings and what prevented their successful implementation. The paper analyses the main constraints and obstacles characterizing these setbacks, and presents different solutions and alternatives to by-pass and/or overcome these obstacles that, if adopted, could enhance the possibilities of successful implementation of the projects.
