Process Optimization
Best practices for aromatics extractive distillation in integrated complexes
Integrated refining/aromatics/olefins complexes are an efficient and effective configuration to maximize crude oil feedstock value and optimize the value of the entire product chain.
Maximizing diesel hydrotreater profit by multivariable optimization: A case study
A diesel hydrotreater (DHT) is a critical unit within an oil refinery. A DHT processes the diesel range fractions obtained from different units of the refinery—such as from the crude distillation unit and the delayed coker unit—to adhere to diesel fuel market specifications.
Selecting the right gas analyzer to optimize monitoring of NOx and other emissions
Combustion processes of all types generate emissions of one kind or another.
Flow modeling as a tool for WHRU performance optimization
Greenhouse gas (GHG) emissions have become a growing concern for many industrialized countries over the past few years.
Use CFD modeling to improve burner design and operation
Process heaters are essential pieces of equipment in the refining and petrochemical industry that are used to heat hydrocarbons to a desired temperature.
Rapid crude yield: Merging DHAFE with HTSD
Rapid crude yield (RCY) combines a detailed hydrocarbon analysis of the front end (DHAFE) with high-temperature simulated distillation (HTSD), creating a true boiling point (TBP) curve for a crude oil sample.
Refining: Despite decline, Group 1 base stocks are here to stay
Given increasingly stringent automotive specifications and the advent of the International Maritime Organization’s 2020 sulfur regulations, the continued decrease in Group I base stocks demand should come as no surprise for anyone in the industry.
Industry Perspectives: The Main Column podcast: Crucial topics shaping the industry
In the February issue of Hydrocarbon Processing, the editors asked our global readership what topics they would like to hear on the publication’s new podcast series: The Main Column.
Processing hydrogen-rich gas in a PSA unit
At Tüpraş’ Kırıkkale refinery, adsorbents in pressure-swing adsorption (PSA) units must be reloaded due to the low hydrogen (H2) recovery and low capacity factor of such units.
Octane enhancement avoiding both high reformer severity and alkylation
An innovative refinery process arrangementa converts butane-rich, light paraffinic streams—preferably containing a high proportion of isobutane—into butylene by dehydrogenation.
