Severe scaling occurs in the circulating water of the secondary cooling unit in petrochemical constant and reduced pressure units
Thread Content
The image below shows the tube bundle of the secondary water cooler in the atmospheric and vacuum distillation towers used in the petrochemical industry. Model FB900-210-16-4, tube bundle material: 10# steel. The operating condition is that the tube side uses circulating water, while the shell side uses a secondary line ； Operating temperature: 30 degrees for the tube side and 127 degrees for the shell side ； The pressure in the tube side is 0.6 MPa, and that in the shell side is 0.64 MPa. This tube bundle has been in use for over a year, and a large amount of scale has accumulated on the circulating water side, affecting the cooling performance of the water cooler. It is recommended to apply a coating on the inner wall of such tubes for scale prevention, which can solve this problem.
It is recommended to clean the tube bundle regularly, check the water quality and carry out water treatment to reduce the accumulation of scale. At the same time, anti-scaling coatings can be considered to prevent the formation of scale and improve cooling efficiency. .
The scaling is too severe. By using our microwave scale prevention and removal equipment, which is installed at the inlet pipe of the circulating water in the heat exchanger to transmit microwave signals into the heat exchanger, scale formation can be effectively prevented. Our equipment has successful experience in scale prevention in sulfuric acid plants, alumina plants, and rare earth plants. WeChat: TigerPeng2014
