COMPARATIVE STUDY OF RELIABILITIES OF DIVIDED WALL DISTILLATION COLUMN AND PETLYUK COLUMN

Abstract

The development in the field of the distillation technology is continued from a long past for the better structure and better column design. This reduces the outer complexity of the system, capital cost, and improves energy efficiency. The Petlyuk column and the divided wall distillation column is such advancement in this field where cost and energy are saved a lot. A reliability study of any system is important as well because it gives an idea that how long the system survive in the working environment. Failure of a system depends on failure of various components of the system and several other factors. If we have a clear idea about the nature of failure, we can easily predict the longevity of the system. Current work is focused on comparing trouble free operational time of a Petlyuk arrangement of two distillation columns vis-à-vis a divided wall distillation column. Different component of the Petlyuk column and the divided wall distillation column, whose probability of failure during the operation is possible, is enlisted and their failure rate assembled through the reliability handbook. Comparison between these two systems gives a picture regarding the better reliable system. It will enhance the chances of application of these columns in various fields with ease and efficient way. This also gives a view about the safety system to be kept in case of the failure of the system. A well protected system last long and save the precious life as well.
