Production of acetone-butanol-ethanol (ABE) through the fermentation process is one alternative that needs to be developed. Less economical in ABE difficulty separation from product and by-products reaction. Among methods, such as extraction, distillation, adsorption, gas stripping, distillation method still most widely used process. The purpose this study was provide recommendations for predic...

E nergy costs are the largest percentage of a hydrocarbon plant’s operating expenditures. This is especially true of the distillation process, which requires substantial energy consumption. Concerns over recent high costs and economic pressures continually emphasise the need for efficient distillation design and operation without a loss of performance. This article illustrates how energy-effici...

Abstract The exergy analysis method is an important for evaluating energy levels and efficiency. It of great importance in the direction process efficiency optimization. In this paper, use coal-to-ethylene glycol distillation comprehensively evaluated analyzed using. Firstly, based on Aspen Plus simulation, basic data were obtained; secondly, a detailed results showed that deethylene unit was l...

This paper presents a series of calculation procedures for computer design of ternary distillation columns overcoming the iterative equilibrium calculations necessary in these kind of problems and, thus, reducing the calculation time. The proposed procedures include interpolation and intersection methods to solve the equilibrium equations and the mass and energy balances. The calculation progra...
