Hydrocarbon plants
GRASYS hydrocarbon separation plants are produced with the use of the company brand-new proprietary membrane capable of delivering substantial benefits in comparison with other gas separation technologies.
Due to their cost-effectiveness combined with required longevity GRASYS membranes may be efficiently used in industrial applications where operating conditions excludes the adoption of other polymer membrane types. Besides, this membrane gas separation technology has a modular structure allowing expansion or modification of operated systems and prompt response to any changes in feed composition during the entire life cycle of a given source (e.g. increasing CO2 concentration or changing hydrocarbon flow composition in a natural gas field) — and all this without unnecessary additional costs. The description below features some of the primary applications of GRASYS gas separation systems
Natural gas sweetening
Today, membranes are used for natural gas sweetening by means of acid gases, CO2 and H2S removal and ensuring its compliance with pipeline requirements as well as for carbon dioxide removal from methane and its subsequent injection in formation in the process of tertiary oil recovery. Frequently, natural gas streams contain aggressive or highly condensable components decreasing membrane capacity. For removal of these components or maintenance/control of their concentration within the membrane capacity critical limits expensive preliminary treatment is required. This restricts the conventional membranes area of application by natural gas processing and increases their functional complexity and operating costs. The new technology makes it possible to develop contamination-resistant and cost-effective membrane systems, highly efficient by gas separation.
