How is gas condensate polishing used in refineries?

In refineries, gas condensate polishing is used to purify the condensate produced during the refining process. This condensate often contains impurities such as dissolved salts, hydrocarbons, and organic contaminants, which must be removed before the water can be reused or safely discharged. Condensate polishing systems in refineries typically use a combination of mechanical filtration, ion exchange resins, and activated carbon to remove these impurities. This process helps protect refinery equipment from fouling and corrosion, improves the quality of the process water, and reduces the environmental impact of wastewater discharge.
