摘要

Refinery off-gas (ROG) is produced in the refinery units that manufacture conversion productsrnsuch as hydrotreaters, alkylation units, FCC, and Platformers. Valuable products includingrnhydrogen, olefins, natural gas liquids (NGL) and higher Btu fuel gas can be recovered from thernoff-gas if a ROG processing unit is installed. The incremental economics of product recovery asrnopposed to using the entire off-gas for fuel provides the incentives for installation of ROG units.rnThe composition of the refinery off-gas stream will vary appreciably depending on the source.rnThe refinery off-gas may contain a number of trace components such as oxygen, ammonia,rnnitriles, acetylenes, sulfur compounds, butadiene, chlorides, arsenic, mercury, and water inrnaddition to acid gases H2S, CO2, and COS. The specifications of the recovered products andrncatalyst requirements will dictate the allowable limits of these contaminants in the feed streamrnMethods for removal of the individual contaminants in the off-gas are detailed in the paper.rnVarious configurations of the ROG plant and associated units are compared depending on therntype of product and feed stock. Optimization strategies required for the design are alsorndiscussed in the paper.

7. Home > All Content > Vol 50, No 1 (2019) Exploring Research–Policy Partnerships in International Development Cover Page Edited by: James Georgalakis and Pauline Rose June 2019 Volume 50 Issue 1 This issue aims to identify how partnerships focused on the production of policy-engaged research seek to achieve societal impact and explores the challenges in these processes. The collaborations analysed span academia, civil society and government, from the grassroots to the national and global levels. By locating these examples within the broader debates on interactions between researchers and research users designed to strengthen evidence informed decision making, this publication offers concepts and practices to inform those funding, designing and undertaking development research. The featured case studies are explored through the perspectives of both researchers and their partners in civil society and policy. They are predominantly taken from a diverse portfolio of research projects funded through the UK’s Economic and Social Research Council (ESRC) and the Department for International Development (DFID) Strategic Partnership. A collaboration with the Impact Initiative, this IDS Bulletin is essential reading for all those in research organisations, development agencies and donors committed to the better use of evidence and learning for development.
