Distillation - Wikipedia

Distillation - Wikipedia

Flash evaporation (or partial evaporation) is the partial vaporization that occurs when a saturated liquid stream undergoes a reduction in pressure by passing through a throttling valve or other throttling device. This process is one of the simplest unit operations, being equivalent to a distillation with only one equilibrium stage.

Thin Film and Wiped Film Evaporators

Thin Film and Wiped Film Evaporators

An LCI agitated thin film evaporator (TFE) or wiped film evaporator (WFE or "wiffe") provides short residence time and open, low pressure drop configuration, allowing continuous, reliable processing of many heat sensitive, viscous, or fouling materials without product degradation.

Condenser Temperature - an overview | ScienceDirect Topics

The condenser pressure and temperature affect the performance of the heat pump cycle and the overall system. Figure 3.15 shows the effect of increasing condenser inlet pressure on the exergy efficiency and energetic COP of the heat pump cycle. When the inlet pressure is raised from 1600 kPa to 1800 kPa, the exergy efficiency of the heat pump cycle rises from 41% to 43% and energetic COP rises .
