Development of a steady-state multiple effect evaporator model and practical application in sugar mills* [Full subscriber]

Abstract The multiple effect evaporator set is an integral stage of a sugar mill and is used to remove the majority of water from sugar cane juice in a steam-efficient manner. Due to the properties of the juice, scale develops on the heat transfer surfaces in each evaporator vessel, which, in Australia, typically require lengthy mill stops every 3–4 weeks to chemically clean and remove. This paper develops a steady-state model of a multiple effect evaporator set and solves it in two ways. The first is to make use of limited information available from actual measurements taken along the Pioneer…
