This course is intended for owners, contractors and in-plant HVAC service technicians who will work regularly with Trane RTHD rotary chillers.

Evaporators - Visual Encyclopedia of Chemical Engineering

In a falling-film evaporator, feed enters from the top of the evaporator. It then flows down the inside walls of the tubes as a thin film. As the feed travels down the tube, evaporation occurs. The vapor/liquid mixture travels down the remaining tube length and into the vapor head. The vapor is removed through the top of the vapor head, while ...

Modeling of crystallization fouling on a horizontal-tube ...

Jun 30, 2021 Scale formation within horizontal-tube falling-film evaporators is an important issue for thermal desalination, because of the deterioration of heat transfer performance and added maintenance costs. Predicting the fouling process is crucial for desalination plant design, operation, and maintenance.
