ACKNOWLEDGEMENTS
First of all I acknowledge, the grace of God the Almighty, in this arduous journey. I would like to thank my parents for their love, care and support without which I wouldn’t have been able to complete the project. I avail this opportunity to thank Prof. K. V. Rao, Academic Head, College of Engineering, UPES, Rajahmundry and Dr. K V Mohana Rao, Centre Director, UPES, Rajahmundry for successful completion of this project. I express my deepest sense of gratitude to Mr. J. S. Prasad, Associate Professor, UPES, Rajahmundry for his guidance and inspiration throughout this project. It has been an experience of great pleasure and satisfaction. Finally I express sincere thanks to all my colleagues, who helped to complete this arduous task directly or indirectly.

EXTENDED ABSTRACT Part I -- The objective of this project is to design a sour gas treatment plant using appropriate solvent. Natural gas with a flow rate of 60MMSCFD (2988.27 Kgmol/hr) with 9 mole% H2 S and is considered. If the outlet H2 S in the Natural gas required is 4ppm then using the process selection figures, the suitable solvents for treating this gas stream are Sulfinol-D, Sulfinol-M, DIPA, MDEA, & ADIP. Sulfinol, as known in basic form consisting of DIPA & Sulfolane is selected as the solvent for the design. The process chemistry of Sulfinol is explained and the equipments involved in the flow sheet are described. Gas properties like molecular weight, specific gravity, compressibility and density are calculated. For
