Chemical Anti-scaling Maintenance for Energy Conservation of Heat Medium Heater

The tube side and shell side of heat medium heaters are susceptible to be blocked due to the coking and the heat efficiency may be reduced due to superheat. Traditional physical cleaning method is time and labour consuming; and hard to reach good anti-scaling result. In order to achieve the cleaning effect and corrosion prevention, the maintaining and cleaning project of the heat medium heater in Longkou natural gas supplier termination of China Petroleum Cooperation (Longkou Termination for abbreviation) was taken as a basis, the technology of anti-scaling cleaning by chemical interfacial active agent was studied. It is shown that the technology has good performance. It can be used in oil industry well and enhance the safe operation effectively.
