Another problem is encountered when chromate inhibitors are used in cooling systems serving compressors that handle sour gas. How To Perfect Your Closed-Loop Systems Application / Industry: Industrial, Hydraulic, Other. Monitoring the water quality of your cooling or heating system may not be a task you have the experience or equipment to do yourself, though. To prevent corrosion in carbon steel components, the water must maintain a high or alkaline pH. Closed cooling water system To cool key processes in petrochemical plants, refineries, power plants and other heavy-duty industrial environments, many plant owners and operators rely on closed-loop cooling as the preferred cooling method. 300 days x 16 hours/day = 4,800 hours. Please enable JavaScript on your browser and try again. -Deionized process cooling water, which can be either open or closed. Specific equipment such as cooling towers, boilers and closed loop systems can use less water than they currently do. Closed-loop Evaporative Cooling Systems A closed-loop evaporative system is a hybrid system. Heat transfer efficiency isnt always easy to monitor and the internal system itself is not visible. All use some sort of water-to-water heat exchanger in con-junction with plant water (dirty water) supplied by a cooling tower, radiator/ fan, refrigeration type chillers, city water, well water, and geothermal field. Mechanical draft cooling is an industrial cooling water system, which involves the use of an evaporation process for cooling. Little, if any, evaporation occurs. This eliminates the discharge of hydraulic cooling water to the drain. Energy Costs = 100 kW 0.3 kW/kW 4,800 hours x $0.1 / kW-hour x 1.0 duty cycle = $14,400 per year. Symptoms of oxygen pitting may be rusty water or recurring maintenance on bearings due to the abrasion caused by the corrosion products against the seal surfaces. Cooling Capacity: 26.38 kW. Lowering the pump speed can conserve energy when cooling needs decrease.
