Digital Exclusive: The eight best practices for moving safety from compliance to a culture of care

In this article, Owens Corning discusses the importance of safety and provide best practices to institute a culture of safety within an organization.

Digital Exclusive-Flare system design: Liquid pockets in flare headers

In this technical article, written by Saudi Aramco and Siemens Energy, the authors focus on areas where major benefits can be achieved early in the front-end engineering design (FEED) stage of flare header piping designs.

Special Focus: Process Optimization

Research and application of proprietary cold oil absorption technology in the recovery of refinery dry gases
Sinopec (Beijing) Research Institute of Chemical Industry: Li, D.  |  Zhang, J.  |  Liu, Z.  |  Guo, L.  |  Hou, Z.  |  Hsu, R.

With the increasing shortage of global energy and resources, the recovery and utilization of refinery dry gases have become important topics of concern.

Several refiners are evaluating a new gasoline-formulation technology called hydrogen (H2)-rich-content (HRC) gasoline. This patented technology uses low-sulfur, H2-rich refinery blendstocks like straight-run gasoline, isomerates, alkylate, butanes and renewable naphtha in gasoline blends, and adds aromatic amines (a high-octane gasoline additive) to make a drop-in specification gasoline.

Tail gas treating units (TGTUs) are designed to remove the last vestiges of unconverted hydrogen sulfide (H<sub>2</sub>S) in the tail gas coming from a sulfur recovery unit (SRU) after the gas has been processed to convert as much H<sub>2</sub>S as possible to elemental sulfur.

Sustainability and the Energy Transition

Transitioning to an electrified future
Siemens Energy: Diezinger, S.

As countries responsible for 75% of greenhouse gas (GHG) emissions set net-zero targets, oil and gas, chemicals and other energy-intensive process industries are under increasing pressure to decarbonize.
