During the 1999-crushing season, the Malelane Mill installed vibratory screens after the quadruple effect evaporator. The purpose of the screens was to separate out any residual scale originating from the chemical cleaning of the evaporator vessels. This strategy was adopted after attempts to improve the flush out of the evaporator vessels after chemical cleaning proved ineffective in removing ...

Two-phase ejectors are devices capable of improving the performance of refrigeration and air conditioning cycles by means of expansion work recovery. Ejector studies often focus on the design and performance of the two-phase ejector and the effect it can have on the performance of the ejector cycle. However, the ejector is not the only component of the system that can have a significant influen...

Experimental investigation was done to find the role of capillary tube length and amount of refrigerant charge on the overall heat transfer coefficient in condenser and evaporator and actual COP of a simple vapour compression refrigeration system. It was concluded that increasing of the refrigerant charge in the system largely enhances the overall heat transfer coefficient in the evaporator by ...

A photonically characterized, modular and open-source falling film looping photoreactor is presented as scalable photochemical platform. Simple geometrical resizing enables a linear increase of reaction rates scale up by factor 10.
