ACKNOWLEDGEMENTS


During the internship at Dinh Co Gas Processing Plant and PV Gas Vung Tau Terminal, I have been helped and enthusiastic by the staff of the factory.


I would like to express my sincere gratitude to the staff members for their guidance, explanation and professional help during my internship at the factory to complete this report.
I would also like to thank the teachers in the Department of Oil Refining, Ha Noi University of Mining and Geology for imparting knowledge, helping me to better approach the actual production process.

Finally, I am very grateful to The Management of Vung Tau Gas Processing Company, Dinh Co Gas Processing Plant and PV Gas Vung Tau Terminal for allowing me to complete this good practice.
