Our 30th anniversary issue is here! This issue of Hydrocarbon Engineering opens with a look into the European refinery sector, and whether short-term gains due to global turmoil are likely to persist, from Contributing Editor, Gordon Cope. The issue then explores key topics affecting the downstream sector, with a number of articles covering developments across catalysts, followed up by discussion of filtration, heat technology, chemical recycling strategies, valves, digital solutions, and much more.
