Petroleum and petrochemical engineering is an emerging field aimed at production of fuels, natural gases and petrochemicals. There has been a tremendous surge in the last few decades for exploration of new hydrocarbon deposits as well as improving the refining and distillation processes for maximum recovery of crude deposits from the reservoirs. It is a multidisciplinary field that includes concepts and technological aspects of geological, mechanical, civil and chemical engineering. This book provides an in-depth explanation of the various processes involved in petroleum and petrochemical engineering such as drilling, processing and technical analysis of petrochemicals. Some of the significant topics included in this book are design of petroleum plants and reservoirs, catalysis and synthesis of petrochemicals, reaction engineering, etc. Students, researchers, experts and engineers associated with petroleum engineering will benefit alike from this book.
