Distillation

Use advanced predictive analytics for early detection and warning of column flooding events

In this study, a methodology was implemented to predict crude distillation tower flooding events based on key process variables, including product yields, column pumparound (PA) flowrates, column temperatures and overhead reflux flowrate.

Refining: Winning strategies for oil producers

Gelder, A., Wood Mackenzie

The prospect of peak oil demand will put pressure on resource-rich national oil companies (NOCs).

Gulf Energy Information and Hydrocarbon Processing are pleased to provide a preview of IRPC Europe 2018, which will be held June 5–7 in Milan.

Establishing a plastics processing sector in NE India—A short analysis

Phukan, P. K., Brahmaputra Cracker and Polymer Ltd.

The Assam gas cracker project was proposed as a part of the implementation of the Assam Accord, which was signed on August 15, 1985.

Modeling and optimization of pressure distillation to achieve pharma-grade THF

Shirpurkar, V., Saudi International Petrochemical Co. (Sipchem)

This case study details the production of tetrahydrofuran (THF), with a purity of 99.96 wt% and water moisture of less than 200 parts per million (ppm).

Industry Perspectives: Secondary unit construction surges in the near term

Nichols, Lee, Hydrocarbon Processing Staff

Although the refining industry is expected to add more than 7 MMbpd of new distillation capacity by the early 2020s, the global refining industry will witness a boost in secondary processing capacity, as well.

Eliminate mechanical seal failure in a crude distillation unit

Telmesani, A. A., Yanbu Aramco Sinopec Refining Company (YASREF) Ltd.

Multiple mechanical seal failures in a crude distillation unit (CDU) resulted in total losses of $3 MM in a refinery since its startup in January 2015. The maximum seal life achieved did not exceed 6 mos, which was much shorter than the American Petroleum Institute (API) 682 “Advancements in Mechanical Sealing” goal of 3 yr of seal life.

Maximizing energy efficiency in paraxylene production—Part 1

Colling, C., BP AMOCO

Due to reduced margins, higher energy costs and rising atmospheric carbon dioxide (CO2) content, energy efficiency has never been more important in refining and petrochemicals.

Details on high-impact refining and petrochemical projects presently under construction, as chosen by HP editors and readers

Nichols, Lee, Hydrocarbon Processing Staff

The global hydrocarbon processing industry (HPI) continues to expand and modernize to efficiently meet growing demand for energy, transportation fuels and petrochemicals.

EIA: More US distillate is being exported

US distillate exports have continued to increase in 2017, both in volume and as a share of total distillate production. Domestic distillate demand has remained relatively stable, increasing slightly from January through July 2017.
