Evaporation Technology

Effectively reduce the tower kettle temperature and improve product quality and yield.

Evaporation TechnologyIntroduction

Falling Film Evaporationis a process in which the liquid feed is introduced into the upper header box of the heating chamber of a falling film evaporator, and then evenly distributed to each heat transfer tube by a liquid distribution and film-forming device. Under the effects of gravity, vacuum induction, and gas flow, the liquid forms an even film that flows down from top to bottom. In the distillation unit, the vapor phase directly enters the tower for distillation, while the liquid phase is discharged from the separation chamber or circulated back into the evaporator by the pump.

Technical Principle of Evaporation Technology

Design conditions: we use the most safe and stable falling film reboiler model in present day, and the falling film introduces the multi-level distribution form including the distribution plate and the film distribution header.

Process Calculation: based on the calculation of advanced simulation software, key parameters such as gasification rate, circulation volume, flooding factor, gas-phase rate, heat exchange area, etc. are determined.

Distributor/Calculation of Film Distribution Header: various hydraulic models are conducted to design distribution system under specific operation conditions, further more hydraulic calculation is operated with independent software.
