Recently, chemical plant of energy saving on production system two diethylene glycol amine.

Based on the process of the system and the equipment carefully analyzed, the coarse two glycol amine raw synthesis system vapor-liquid separator into the separation of tundish, no longer through the condenser, cooler two synthesis system of heat exchange equipment, directly through the pipeline into the separation system in ammonia stripping tower. After the transformation, so that the original 30-60 of deamination tower inlet temperature increased to more than 120 degrees, which not only saves the medium pressure steam consumption, but also can optimize the process, to ensure the stability of operation. After a period of operation, the average class steam savings of 1.5 - 3 tons.
