CHAPTER 21: EVAPORATION – PRINCIPLES, TYPES OF EVAPORATORS

CHAPTER 21: EVAPORATION – PRINCIPLES, TYPES OF EVAPORATORS. Evaporation is an operation used to remove a liquid from a solution, suspension, or emulsion by boiling off some of the liquid. It is thus a thermal separation, or thermal concentration, process. We define the evaporation process as one that starts with a liquid product and ends up with a more concentrated, but still liquid

Drawing (manufacturing) - Wikipedia

Drawing is a metalworking process which uses tensile forces to stretch metal, glass, or plastic.As the metal is drawn (pulled), it stretches thinner, into a desired shape and thickness. Drawing is classified in two types: sheet metal drawing and wire, bar, and tube drawing. The specific definition for sheet metal drawing is that it involves plastic deformation over a curved axis.
