Two effect evaporator
WebCompared to a single effect evaporator, the capacity of a n-effect evaporator is n times greater, and the economy is 0.8 n. The cost of pumping liquid from one effect to another is higher because of the interconnecting pipes, valves, and pumps necessary. It is more economical to use a multiple effect evaporator than a single effect evaporator ... WebFigure 2. Temperature profile in single-effect and condenser arrangement. 2.1.

Because the molecules of a liquid are in constant motion, we can plot the fraction of molecules with a given kinetic energy (KE) against their kinetic energy to obtain the kinetic energy distribution of the molecules in the liquid (Figure \(\PageIndex{1}\)), just as we did for a gas.As for gases, increasing the … http://ethesis.nitrkl.ac.in/1911/1/10600012.pdf
WebThe multiple-effect evaporator requires a supply of saturated steam extracted from an extraction–condensing steam turbine at a specified pressure. An adverse consequence of the exposure of sugar juice to high-temperature steam and vapor in the multiple-effect evaporator is sucrose inversion loss, which converts sucrose to glucose and fructose. WebEvaporation efficiency. A two-effect falling-film evaporator with thermocompressor requires about 0.32 kg of steam to evaporate 1 kg of water, and a five-effect evaporator requires …
WebProses evaporasi terdiri dari dua peristiwa yang berlangsung : 1. Interface evaporation, yaitu transformasi air menjadi uap air di permukaan tanah. Nilai ini tergantung dari tenaga yang tersimpan. 2. Vertical vapour transfers, yaitu perpindahan lapisan yang kenyang dengan uap air dari interface ke uap (atmosfer bebas).
