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.
Determining the indeterminate
Standards such as API, ASME and NFPA are applied widely in the refining industry.
A solution to the IMO 2020 MARPOL Annex VI requirement
On January 1, 2020, a new requirement limiting the sulfur content of marine fuel to a maximum of 0.5 wt% went into effect.
Meeting the Tier 3 challenge with ultra-clean alkylate
The U.S. Environmental Protection Agency (EPA) introduced Tier 3 gasoline sulfur standards in 2017, requiring all U.S. gasoline producers to adhere to an annual 10-ppm average sulfur limit.
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.
