Description

Technical Field

[0001] This utility model relates to the field of chemical product production technology, and in particular to an automatic temperature control device for high-freezing-point ethanolamine materials. Background Technology

[0002] The diethanolamine (DEA) used in the ethanolamine production process has a freezing point of 28℃, while triethanolamine (TEA) has a freezing point of 21.6℃ (DEA is used as a representative medium for high freezing point materials in the following description). Within this temperature range, both media will solidify or become viscous, affecting their fluidity. If condensation occurs on the inner walls of pipes and pumps, it can lead to pipe blockage, difficulty in starting pumps, and in severe cases, damage to pumps, impacting production efficiency and safety. Currently, similar equipment often uses jacketed hot water tracing or steam tracing for diethanolamine pipes and pumps, which suffers from high energy consumption, high operating costs, inaccurate temperature control, and a tendency to overheat materials. Because diethanolamine is harmful to aquatic organisms and has long-term, continuous effects, leaks in the jacket can allow diethanolamine to enter the hot water or steam condensate, easily causing water pollution and environmental incidents. Furthermore, subsequent wastewater treatment will increase production costs. Utility Model Content
