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.
Design considerations when flaring ethylene oxide
The flaring of gases released from normal process vents and safety valve discharges following an overpressure scenario is widely practiced in refineries, petrochemical and chemical plants.
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.
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.
