The ROI (Return On Investment) is an especially important efficiency metric utilized to assess the performance of an investment or to relate the performance among a handful of investments. In order to compute ROI, the profit (return) of such an investment for our purposes the formula used is ROI= (Gain from Investment - Cost of the Investment) while in the original formula the upper result is divided by the price of the investment and then the outcome is written as a percentage. Return on investment is a highly widespread numerical method due to its flexibility and ease in use. Continue reading...

Abstract

In the laboratory assignment, the experimental investigation of the distillation process is performed. The mixture of dichloromethane and trichloroethylene was separated using the glass distillation column. The influence of power input on temperatures and column flow rate was investigated. Apparently, the power input increases the efficiency of the process. The experiment had three main tasks: study of the variation of the pressure drop, application of refractometer as an express method of binary mixture composition analysis, and estimation of the column efficiency.
It has been proven that the boil-up rate is directly proportional to pressure drop. Although there is some Continue reading...
