Desulfurization
Editorial Comment: Maintenance and reliability—A cornerstone of safe and efficient plant operation
Refineries and petrochemical plants are comprised of a series of crucial processes to produce transportation fuels, products and chemicals demanded by the global market. These processes consist of capital-intensive units that must be maintained to provide reliable performance. Failure to adequately maintain these assets can have a detrimental effect to not only operations and profit, but also to worker safety.
Editorial Comment
Over the past several decades, the hydrocarbon processing industry has invested heavily in new processing units to produce low-sulfur and ultra-low-sulfur (ULS) transportation fuels.

Leveraging digital technologies to create the smart renewable diesel facility
Many companies are modifying existing crude refineries or building grassroots renewable diesel facilities to produce drop-in, green renewable diesel from a variety of agriculturally derived triglyceride feedstocks.
Reducing acid consumption: Maximizing sulfuric acid alkylation unit profitability
Alkylation is a process used to produce highly branched isoparaffins from the reaction of lighter olefins and isobutane in the presence of sulfuric acid as a catalyst.
Converting a petroleum diesel refinery for renewable diesel
As refiners consider renewable, low-carbon alternatives, renewable diesel—refined from agricultural products using petroleum refinery processes—is gaining traction.
Industry Perspectives
The hydrocarbon processing industry (HPI) is steadily advancing through the energy transition.
