Rapid crude yield: Merging DHAFE with HTSD

Ingham, H., Chevron

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

Nadasdi, T., ExxonMobil

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

Nichols, Lee, Hydrocarbon Processing Staff

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

Kauders, P., CDE Projects Ltd.

An innovative refinery process arrangementa converts butane-rich, light paraffinic streams—preferably containing a high proportion of isobutane—into butylene by dehydrogenation.

Cost-effective naphtha hydrotreating unit revamp to increase high-octane reformate production

Ramesh, K., Phukan, D., Indian Oil Corp. Ltd.

India, which is the third-largest economy in the world, is home to nearly 18% of the world’s population (nearly 1.4 B).

Safety: Where foresight replaces hindsight: How AI impacts the future of oil and gas safety

Stewart, H., Advisian Digital, part of the Worley Group; Aitken, C., SaltGrid

According to the International Association of Oil and Gas Producers (IOGP), there were 31 fatal incidents across the industry in 2018.

Demineralized water system design: Considerations for the petrochemical industry—Part 1

Fan, J., Ananthanarayan, S., Hodgkinson, A., Advisian, a Worley Company

Site utility leads, engineers and other professionals in the hydrocarbon/chemical processing industries (HPI/CPI) are facing a perfect storm of increasing demineralized water demand, end of life of existing demineralized water plant equipment, changing source water quality, corporate directives to diversify water sources, and pressure from regulators and community stakeholders to minimize the volume of waste generated from water treatment.

Variable capacity control technology facilitates efficient operation for reciprocating compressors

Sanford, J., Siemens

Reciprocating compressors are used extensively in refinery and petrochemical operations to keep feedstocks and products moving through miles of piping.

Improving plant operations with control valve simulations

Novak, L., Youngdahl, R., Emerson Automation Solutions

In today’s business climate, where project budgets and schedules are under cost and time pressures (and where installed valve applications must perform reliably under increasingly severe conditions), valve simulations are enabling new capabilities.
