• MEG Regeneration and Reclamation

    With our unrivaled experience in the design and delivery of monoethylene glycol (MEG) regeneration and reclamation units worldwide, we can provide an optimum solution to fit client- and field-specific needs. Our slip-stream and full-stream concepts have been extensively developed, tested, and operated, resulting in continuously improved products.

    Description

    Through our expert understanding of field chemistry and the overall MEG loop, combined with our long experience with particle and corrosion product management, our solutions are particularly robust, offering high availability and low MEG losses. We have extensive knowledge of the impact of production chemicals and through the use of our testing facilities we are able to advise on the handling and clean-up of such with our MEG reclamation system. Our vast in-house technology portfolio allows us to bundle the MEG system with upstream hydrocarbon removal and downstream produced water treatment, offering a seamless route to meeting requirements while reducing weight, footprint, utilities, and cost. Design configurations vary to meet specific field requirements and include:
     
    Full-stream MEG regeneration systems
     
    Our full-stream MEG regeneration systems treat the entire rich MEG feed for removal of salts, corrosion products, organic acids, and other impurities. The design produces a clean, lean MEG stream which reduces the risk of scaling in the subsea system. The combined re-concentration and reclamation process is performed under vacuum, minimizing energy consumption as well as avoiding thermal degradation conditions for MEG. 
     
    Our design has been developed over 15 years to ensure reliability, efficient salt handling, and low MEG losses. 
     
    Slip-stream MEG regeneration systems
     
    In this instance, the MEG is pre-treated to remove hydrocarbons, low-soluble salts, and corrosion products, before the water is removed through distillation. A slip stream of lean MEG is treated in a vacuum re-claimer to control the content of high-soluble salts.
     
    The slip-stream system design gives high reliability, operational flexibility, and low energy consumption in addition to efficient salt handling and low MEG losses. This concept enables the design of systems with very large capacities.
     
    Advanced MEG 
     
    The advanced MEG systems combine full- and slip-stream processes with advanced technologies to improve handling and removal of hydrocarbons, organic acids, mercury, kinetic hydrate inhibitors, and other impurities from the closed MEG loop.
     
    Conventional MEG
     
    When no formation water—and hence no salt production—is expected from the reservoirs, conventional regeneration systems are used to distill the rich MEG feed and meet the required lean MEG concentration. Tie-ins can be prepared for retrofitting a slip-stream vacuum re-claimer for added flexibility and security. 
     
    Our conventional MEG regeneration systems combine state-of-the-art technology with low costs and minimal footprint.
