PREFACE
We feel immense pleasure in presenting before you this final report on our PS-1 program IOCL Guwahati refinery. This report encompasses a comprehensive discussion of what we learnt on this program.
The report starts with a brief introduction about the organization i.e. IOCL Guwahati refinery. We have kept discussion in this section brief to focus more on our Project
‘Heat exchange and integration in CDU ’.
The main report is divided into 4 sections. To start with, the first Section is a basic introduction to Crude distillation unit, its process and products.
Heat exchange is among the most important activity for crude distillation units. The
2nd part of the report focuses on this heat exchange process occurring in the crude distillation unit of Guwahati refinery. Necessary data regarding all the heat exchangers has been provided in a tabular manner to make understanding easier. The concept of critical heat exchanger is introduced subsequently in the 3rd section along with the case study of some important heat exchangers of the process. Heat duty
&other calculations presented in this section for heat exchangers are clearly explained in step by step manner along with formulas used. Through these calculations we have tried to analyze whether these exchangers are working efficiently.
In the Last part of the report we have given an introduction to ‘heat integration’ one of the most important tool for increasing energy efficiency of a process. Points discussed about heat integration in this section are: Meaning, Importance, its need in
CDU, Tools. We have concluded this part with an example of heat integration done in
2010 in pre-heat train of CDU, showing how it
