With demand for petroleum products increasing worldwide, there is a tendency for existing refineries to seek new approaches to optimize efficiency and throughput. In addition, changes in product specifications due to environmental regulations greatly influence the development of petroleum refining technologies. These factors underlie the need for this fifth edition of The Chemistry and Technology of Petroleum, which continues in the tradition of the bestselling fourth edition, proving readers with a detailed overview of the chemistry and technology of petroleum as it evolves into the twenty-first century. The new edition has been updated with the latest developments in the refining industry, including new processes as well as updates on evolving processes and various environmental regulations. The book covers issues related to economics and future refineries, examines the changing character of refinery feedstock, and offers new discussions on environmental aspects of refining. It contains more than 300 figures and tables, including chemical structures and process flow sheets. A useful reference for scientists and engineers in the petroleum industry as well as in the catalyst manufacturing industry, this book introduces readers to the science and technology of petroleum, beginning with its formation in the ground and culminating in the production of a wide variety of products and petrochemical intermediates.
The Chemistry and Technology of Petroleum, Third Edition fully covers the subject, from the underground formation of petroleum to recovery of refined products. The third edition contains additional chapters on the structure of petroleum, refining heavy feedstocks, instability and incompatibility in petroleum products, environmental aspects of refin
This book employs new archaeological and historical evidence to explain how and why Roman Britain became Anglo-Saxon England.
This book offers a radical perspective on what are conventionally called the Islamic Conquests of the seventh century. Placing these earthshattering events firmly in the context of Late Antiquity, it argues that many of the men remembered as the fanatical agents of Muḥammad probably did not know who the prophet was and had, in fact, previously fought for Rome or Persia. The book applies to the study of the collapse of the Roman Near East techniques taken from the historiography of the fall of the Roman West. Through a comparative analysis of medieval Arabic and European sources combined with insights from frontier studies, it argues that the two falls of Rome involved processes far more similar than traditionally thought. It presents a fresh approach to the century that witnessed the end of the ancient world, appealing to students of Roman and medieval history, Islamic Studies, and advanced scholars alike.
The last and longest war of classical antiquity was fought in the early seventh century. It was ideologically charged and fought along the full length of the Persian-Roman frontier, drawing in all the available resources and great powers of the steppe world. The conflict raged on an unprecedented scale, and its end brought the classical phase of history to a close. Despite all this, it has left a conspicuous gap in the history of warfare. This book aims to finally fill that gap. The war opened in summer 603 when Persian armies launched co-ordinated attacks across the Roman frontier. Twenty-five years later the fighting stopped after the final, forlorn counteroffensive thrusts of the Emperor Heraclius into the Persians' Mesopotamian heartland. James Howard-Johnston pieces together the scattered and fragmentary evidence of this period to form a coherent story of the dramatic events, as well as an introduction to key players-Turks, Arabs, and Avars, as well as Persians and Romans- and a tour of the vast lands over which the fighting took place. The decisions and actions of individuals-particularly Heraclius, a general of rare talent-and the various immaterial factors affecting morale take centre stage, yet due attention is also given to the underlying structures in both belligerent empires and to the Middle East under Persian occupation in the 620s. The result is a solidly founded, critical history of a conflict of immense significance in the final episode of classical history.
