Air-cooled heat exchanger under natural convection http://admin.hydrocarbonprocessing.com/magazine/2022/october-2022/heat-transfer/air-cooled-heat-exchanger-under-natural-convection Determining whether or not to operate an air-cooled heat exchanger (ACHE) under natural convection is a challenge due to the limited information available for simulations of an ACHE under operation without fans. 2022 <em>HP</em> Awards Finalists http://admin.hydrocarbonprocessing.com/magazine/2022/october-2022/emhydrocarbon-processingem-awards-2022/2022-emhpem-awards-finalists Hydrocarbon Processing, the downstream processing sector’s leading technical publication for 100 yr, has announced the finalists for its sixth annual HP Awards, which celebrate innovative technologies and people that have been instrumental in improving facility operations over the past year. Case studies: Evaluation of the soundness and remaining life of PSA vessels with weld defects http://admin.hydrocarbonprocessing.com/magazine/2022/october-2022/maintenance-and-reliability/case-studies-evaluation-of-the-soundness-and-remaining-life-of-psa-vessels-with-weld-defects Multiple defects were found in pressure swing adsorption (PSA) vessels during an outage of one of four PSA process units. Sustainable steel/chemicals production: Removal of impurities for valorization of steel mill gases http://admin.hydrocarbonprocessing.com/magazine/2022/october-2022/special-focus-plant-safety-and-environment/sustainable-steelchemicals-production-removal-of-impurities-for-valorization-of-steel-mill-gases Industry faces significant challenges relating to the transition toward cleaner energy and more sustainable feedstocks. Use CFD analysis to evaluate the impact of hot air recirculation on air-cooled heat exchangers http://admin.hydrocarbonprocessing.com/magazine/2022/august-2022/heat-transfer/use-cfd-analysis-to-evaluate-the-impact-of-hot-air-recirculation-on-air-cooled-heat-exchangers Air-cooled heat exchangers are widely used in the petroleum, petrochemical, natural gas and other industries for cooling purposes. In contrast to a water-cooled system, which consists of a traditional shell-and-tube heat exchanger and a cooling tower, an air-cooled heat exchanger uses ambient air as the main cooling medium. HRSG water/steam sampling: Do it right or face potential consequences http://admin.hydrocarbonprocessing.com/magazine/2022/july-2022/process-optimization/hrsg-watersteam-sampling-do-it-right-or-face-potential-consequences Many large industrial facilities—including refineries, and chemical and petrochemical plants—are increasingly turning to co-generation for process steam and power production. BASF and MAN Energy Solutions enter into partnership for construction of one of the world’s largest heat pumps in Ludwigshafen http://admin.hydrocarbonprocessing.com/news/2022/07/basf-and-man-energy-solutions-enter-into-partnership-for-construction-of-one-of-the-world-s-largest-heat-pumps-in-ludwigshafen This project is intended to make an important contribution to reducing greenhouse gas emissions, establishing the use of low-CO2 technologies in chemical production and reducing the site’s natural gas consumption. Lummus Technology launches next generation of breech-lock high-pressure heat exchanger closure http://admin.hydrocarbonprocessing.com/news/2022/06/lummus-technology-launches-next-generation-of-breech-lock-high-pressure-heat-exchanger-closure Lummus Technology announced the launch of its Polaris breech-lock closure, a new technological upgrade applicable to its high-pressure heat exchanger equipment.
