Simulation and design of distillation units for treatment of sulphite pulping condensates to recover methanol and furfural. Part II: Applicability of multi-effect distillation using live steam
(1979) In Canadian Journal of Chemical Engineering 57(3). p.316-320- Abstract
- A distillation unit has been designed for a capacity of 73 t/h of condensate and for at least 90% recovery of the contaminating organics. This unit consists of three columns: a primary stripper to remove volatile organics and two upgrading columns to purify the methanol and furfural byproducts.
Three different energy-saving alternatives for satisfying the energy requirements have been studied: utilisation of secondary steam from the evaporation plant, and application of the principle of multi-effect distillation in one-stripper and in two-stripper configurations.
Investment cost needed in all alternatives amounts to 5.5–6.0 MCr (millions of Swedish Crowns) while operating cost varies between 0.8–3.1...
