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.
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.
Business Trends: A perspective on new technology impacts on the chemical processing industry
Over the past five years, the industrial evolution has been propelled by the same technologies that have dramatically changed our private lives.
Implement effective operational discipline programs to improve process safety performance—Part 2
Operational discipline (OD) describes human behavior in complying with required systems, every time, to consistently achieve organizational goals and overall operational excellence.<sup>1,2</sup>
Down with downtime: Repair complex petrochemical components with selective electroplating
The volatile impact of the coronavirus pandemic hit at the same time the petrochemical industry was entering a downcycle.
Optimizing failure data analysis
A critical objective of engineers who design an automatic protection system is to lower the false trip rate and to lower a key metric called average probability of failure on demand (PFDavg).
