Calculation of ethylene glycol production in a reaction-rectification column

Petroleum Chemistry, 2007
Principles for the development of a mathematical model for a reaction-rectification column are presented. The influence of the main technological parameters on the operation of the rectifying reaction column for ethylene glycol production is considered. It was shown that the reflux/ethylene oxide ratio has an effect primarily on the quality of ethylene

Effects of water on steam rectification in a packed column

Chemical Engineering Research and Design, 2011
Abstract The effects of water on steam rectification, i.e., multi-stage saturated steam distillation, were investigated in a packed column. N-octane–p-xylene and 1,3,5-trimethylbenzene–1,2,4-trimethylbenzene were used as test systems. Both binary systems are nearly ideal systems and insoluble in water, thus the effects of water in steam rectification

Theoretical study of ethylene glycol synthesis in a reaction-rectification column

Russian Journal of Applied Chemistry, 2006
Principles of construction of a mathematical model of a reaction-rectification column for ethylene glycol synthesis are considered. Some specific features of the operation of the reaction-rectification column are analyzed. The correctness of the assumptions and limitations of the model is substantiated and the adequacy of the model is assessed.

The Impact of Reflux Ratio on Rectification Column Theoretical Plate Number

Advanced Materials Research, 2011
In this paper, the computer-aided calculation is introduced to study the influences of the reflux ratio on the theoretical plate number of rectification column. It is found that the number of theoretical plates of rectification column is increasing as the decreasing of the reflux ratio, which is mainly caused by the increasing of the plate number in ...
