Description Thermal power plants powered by either nuclear energy or fossil fuel located along a seacoast normally use seawater as a coolant in the steam condensers. These are typically once through cooling water systems Electro chlorination plant in above mentioned types of application has considered as the most effective, low operating cost and safety operation method in order to control the marine growth at the seawater intake structure. Onsite hypochlorite package well known as the best method to prevent accumulations of marine life in the seawater intake line of the various plants, because no dangerous liquid or gaseous chlorine is required. Process Flow Bio fouling control is one of the main challenges in the upstream processes of the power station is to protect pipeline and process equipment against biological fouling. Restriction of cooling water flows, acceleration of corrosion and a reduction in the overall life of process equipment can all be controlled by the effective design of our electro chlorination package. Seawater Electrochlorination unit system packages play an effective role in optimizing flow assurance.All Rights Reserved
