A REPORT ON CDU: HEAT EXCHANGE and INTEGRATION BY Mudit 2010A1PS349P Amanpreet Singh 2010B4A1356P Rishu Gupta 2010A1PS401P AT IOCL REFINERY, GUWAHATI A Practice School-I station of BIRLA INSTITUTE OF TECHNOLOGY and SCIENCE, PILANI July, 2012 PREFACE We feel monstrous delight in introducing before you this last report on our PS-1 program IOCL Guwahati treatment facility. This report envelops a far reaching conversation of what we realized on this program. The report begins with a concise presentation about the association I. e. IOCL Guwahati refinery.We have kept conversation in this segment brief to concentrate more on our Project ‘Heat trade and coordination in CDU ’. The principle report is partitioned into 4 segments. To begin with, the main Section is a fundamental prologue to Crude refining unit, its procedure and items. Warmth trade is among the most significant movement for unrefined refining units. The second piece of the report centers around this warmth trade p rocess happening in the rough refining unit of Guwahati treatment facility. Fundamental information in regards to all the warmth exchangers has been given in a plain way to make understanding easier.The idea of basic warmth exchanger is presented in this manner in the third area alongside the contextual investigation of some significant warmth exchangers of the procedure. Warmth obligation &other figurings introduced in this area for heat exchangers are unmistakably clarified in bit by bit way alongside equations utilized. Through these computations we have attempted to break down whether these exchangers are working productively. In the Last piece of the report we have given a prologue to ‘heat integration’ one of the most significant instrument for expanding vitality productivity of a process.Points examined about warmth joining in this segment are: Meaning, Importance, its need in CDU, Tools. We have finished up this part with a case of warmth incorporation done in 2010 in pre-heat train of CDU, demonstrating how it helped sparing vitality and expanding proficiency. A last end and glossary are given to summarize the report. We trust you make some great memories perusing this report and think that its educational and valuable. Mudit, Amanpreet and Rishu Birla Institute of Technology and Science Pilani 333031 2 ACKOWLEDGEMENTA exhaustive report consistently requires the generosity, consolation, direction and backing of numerous individuals so we might want to begin by saying thanks to our school BITS pilani for starting project like ps-1 accordingly giving us the chances to visit ongoing ventures and learn by taking a shot within reach in associations as large as IOCL. Our earnest gratitude to Mr. B K Das, CPNM and Mr. P S Sonowal for doling out us this significant undertaking on heat reconciliation in treatment facility and getting us in contact with the necessary individual in every unit. Without their assistance this entire program would n ot have been possible.We are obligated by the consistent help and coaching gave by Mr. Vijay Kumar, TS for the arrangement of this report. Likewise, we accept this open door to thank all the central designers, and laborers we have met in various units who have gotten us with open hearts and helped us in learning the huge range of information that a treatment facility holds. Mr. E Edmund of CDU, Mr. A. Bairagi of OM&S are only the couple of these names with whom we shared various instructive talks which at long last went into the planning of this report. We additionally express our profound feeling of appreciation to IOCL organization for giving us fundamental information nd making our stay a wonderful one. Because of our families and companions for their consistent help and support all through the time of readiness of this report. It's a given that we are earnestly thankful to our teacher, Mr. Prasantha G for organizing this ps-1 program and giving us chance to introduce before him this report.

To expand the temperature of unrefined 2 stage process is utilized; heat trade with item streams and heater. In the shell and cylinder type heat exchangers of Guwahati treatment facility Low temperature unrefined trades heat with high temperature surges of SRGO, RCO and so on in 3 stages(cold , mid, hot). The presentation of a portion of these warmth exchangers majorly affect creation and are delegated ‘Critical' based on various measures like successive fouling, Large surface area.Calculation of warmth obligation, LMTD of a portion of these warmth exchangers(s/15, S/23a-b,s-24) is finished utilizing structure and handy information to che ck whether they are working proficiently when contrasted with plan. Warmth joining is a significant idea to expand vitality productivity of procedure through warmth recuperation. Apparatuses like squeeze investigation are utilized in high vitality requesting units like CDU to improve the Heat Exchanger Network for most extreme productivity. Examination of past warmth reconciliation done in Pre heat train of CDU is taken for instance for investigation.

The report depends on Work in CDU of Guwahati treatment facility. Unrefined refining units are utilized for the fractionation of rough into increasingly significant items utilizing their distinction in breaking points. Increment in temp for refining us accomplished in 2 stages; initial step is the warmth trade of unrefined with item streams at high temperatures. In the following stage a heater is utilized to additionally lift the temperature.Our primary concern of conversation in this report is the initial step of warmth trade called the Pre-heat train. The pre-heat train comprises of 3 segments: Cold, Mid and hot. The motivation behind each area is to recuperate heat from hot item stream of RCO, SRGO and so on and gracefully it to unrefined through a shell-tube type heat exchanger. The insights regarding different warmth exchanger utilized in process are introduced in the report. Execution of some warmth exchanger is more basic on generally heat trade than others; these warmth exchangers are delegated ‘Critical heat exchangers'. Consistent observing of productivity of these warmth exchangers should be done.As Example counts like warmth obligation, LMTD is done in this report for a portion of these basi c warmth exchangers (S-11C, S-23A/B) to check their proficiency. Unrefined refining is a vitality serious procedure. With expanding oil costs, the center is to augment vitality recuperation. One approach to do this is ‘heat reconciliation' which is a method to plan a procedure to limit vitality utilization. Devices like squeeze examination are utilized for acquire an enhanced warmth exchanger arrange for heat mix in CDU. The retrofitting of the HEN in CDU is taken as contextual investigation in report to acknowledge significance of warmth integration.Meaning of all the key terms utilized in the report can be found in the Glossary. Vital information utilized in the report has been gotten through manuals and authorities of Guwahati treatment facility.
