Gordon Cope, Contributing Editor, considers how war in the Middle East is permanently changing the foundations of the North American energy sector.
Integration for optimisation
Ashutosh Patil, Himanshu Chauhan, and Adrien Serve, UNICAT, illustrate how an integrated suite of modelling and data reconciliation tools can provide hydrogen/syngas plant operators with assurance of catalyst health to enable optimised plant performance throughout the full catalyst service life.
Zeolites in the circular refinery
Dr. Danny Verboekend, Zeopore Technologies, discusses how accessible, mesoporous zeolites can aid refineries as they seek to adopt circular processes amid the need for decarbonisation.
Unlocking profit in naphtha hydrotreating units
Xavier E. Ruiz Maldonado and Mohamed Khalil, Topsoe North America, discuss how refiners can increase profit in naphtha hydrotreating units with advanced technology and catalyst solutions.
Better dewaxing through intra-bed redispersion
Vikash Patel, Crystaphase, USA, describes how a targeted redispersion technology installed within a diesel dewaxing bed at a North American refinery helped support higher diesel production by improving gas-liquid distribution.
In times of change: a process screening solution
A. Müller, G. Wasserschaff, N. Brem, and E. Dhaouadi, hte, explore how a flexible compact unit with a lower degree of parallelisation could improve catalyst screening and process optimisation amid changing market demands.
The essentials of precious metals recovery
Recovering precious metals from spent catalysts is a high-stakes process where accurate sampling, ethical refining, and technical expertise are important. Brad Cook, Sabin Metal Corp., USA, explains.
Methanol’s moment
Robert Jolly, Johnson Matthey, discusses how operators can use elements of established loop and reactor designs from conventional coal and natural gas-based plants to de-risk sustainable methanol projects.
A unique approach to alkylation – part 2
In the second of this two-part article, Bhavdip Kalaria, KBR, presents selected case studies that demonstrate how solid acid alkylation can be used in refineries and petrochemical operations.
