Paperback. Condition: New. Oil recovery efficiency can be increased by applying the enhanced oil recovery (EOR) processes, which are based on the improvement of mobility ratio, reduction of interfacial tension between oil and water, wettability alteration, reduction of oil viscosity, formation of oil banks, and so forth. This book describes the different EOR methods and their mechanisms, which are traditionally used after conventional primary and secondary processes. The present scenario of different EOR processes, at both the field application stage and research stage, is also covered. Further, it discusses some of the recent advances in EOR processes such as low-salinity water flooding, the application of nanotechnology in EOR, microbial EOR, carbonated water injection, etc. Features: Comprehensive coverage of all enhanced oil recovery (EOR) methods Discussion of reservoir rock and fluid characteristics Illustration of steps in design and field implementation as well as the screening criteria for process selection Coverage of novel topics of nanotechnology in EOR and hybrid EOR method and low-salinity waterfloods Emphasis on recent technologies, feasibility, and implementation of hybrid technologiesThis book is aimed at graduate students, professionals, researchers, chemists, and personnel involved in petroleum engineering, chemical engineering, surfactant manufacturing, polymer manufacturing, oil/gas service companies, and carbon capture and utilization.…

Taschenbuch. Condition: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Fly ash has been converted to zeolite using alkali fusion followed by hydrothermal treatment. The synthesis conditions were optimized to obtain highest conversion of fly ash to X-type zeolite. The prepared catalyst has demonstrated good efficiency in catalytic cracking of pure components, like n-Heptane, as well as heavy gas oil. The cracking activity of synthesized catalyst showed comparable activity with 13X zeolite and FCC catalyst collected from Bharat Petroleum Corporation Ltd., India. The activity of the synthesized catalyst has been tested for lkylation of phenol. The prepared catalyst has been found to be superior to the commercially available catalyst like 13X and H-Beta. The cracking and alkylation reactions were carried out in a fixed bed down flow reactor and also in batch reactor. Kinetic models were developed for both for cracking and alkylation reactions and kinetic parameters and adsorption constants were estimated using a non-linear regression algorithm. The outcome of the present study is very much promising in utilizing a waste material into a commercial commodity and also to protect environmental pollution to some extent. 220 pp. Englisch.…
