Hydrogenation unit air cooler
Thread Content
Why is the hydrogenated oil after hydrogenation cooled by an air cooler, rather than by water cooling or other heat exchangers?
Air cooling offers excellent energy-saving effects! Using a heat exchanger increases energy consumption on one hand, and the investment cost is also high on the other hand
Water-cooling scaling happens quite often~~~ Is it costly?
1. Facilitates the identification of leak points； 2. Easy to put into use and maintain ； 3. Low operating costs.
Looking at the prices of local water sources, it is mostly to save water
An air cooler is a type of partitioned heat exchanger that uses air as the cooling medium, forcing air to flow over the fins outside the heat transfer tubes in order to cool the fluid inside those tubes; it can be used as both a cooler and a condenser. Compared to water cooling, air coolers can save a large amount of cooling water, reduce water pollution in industrial areas, and lower factory investment and maintenance costs. Especially in water-scarce areas, replacing water cooling with air cooling can alleviate the shortage of water resources.
Air cooling is more economical; it reduces the amount of circulating water needed and lowers the water consumption per unit of the installation. Air cooling is generally used at temperatures around 150°C, while water cooling tends to cause scaling
Considering several aspects: 1. The cooling effect of air cooling is much better than that of water coolers. 2. It helps save water resources by reducing water consumption. 3. The inlet temperature for air cooling is usually around 200 degrees Celsius, and the large temperature difference compared to water coolers makes it unsuitable to use water cooling directly
