This article details the advancements in the authors’ company’s plus catalyst series of syngas catalysts that improve efficiency, sustainability and profitability in ammonia, methanol and hydrogen production.

To address various challenges, the authors’ company has developed a selective dewaxing catalyst suitable for fossil feeds, co-processing and 100% renewable services. This article details this novel technology.

Based on the generation and conversion mechanism of butylenes during the FCC process, this article details the design, development and commercial trials of the latest high-butylenes selectivity catalysts (HBC) series catalysts boosting butylenes without compromising gasoline yield. Its potential to increase butylenes has been confirmed through laboratory evaluation and commercial trial results. 

Although cost cutting provides short-term financial benefits, it does not improve anything operationally in a plant. The reality is that most companies have already pushed such programs to their practical limits. So, what is left? The alternative approach is improving performance through operational excellence. This article will unpack this approach with examples of how producers have benefitted from it.

This article details a process that ensures efficient gas treatment, compliance with environmental standards, and the optimal use of chemicals and resources. 

This article will discuss the critical parameters that could potentially affect the performance of a residue fluid catalytic cracking plant’s main fractionator and gas concentration (gascon) section columns. It will also elaborate on how the systematic troubleshooting methodology helped to solve the problems and improve column performance. 

This article analyzes the causes of a 19-mm protrusion of the tube sheet and the tube joint leaks that occurred within a sulfur recovery unit (SRU) waste heat boiler (WHB).

Double disc isolation valve technology could hold the key to optimizing dangerous fluid catalytic cracking unit (FCCU) maintenance and repair processes at refineries. This article explores the key considerations behind refinery turnarounds and how they can be made safer and more efficient. 

Transition pieces, designed to bridge the gap between such dissimilar materials, are crucial to ensure system integrity and performance in these demanding environments. In this article, the authors explore a few transition piece usage situations and attempt to elucidate the challenges and approaches adopted. 

By aligning the right skills and employing best practices for knowledge transfer and project risk assessment, a project development team can anticipate common issues, find fatal flaws quickly and generate vital insights as early as possible, leading to a successful project.
