Distillation
Modeling and optimization of pressure distillation to achieve pharma-grade THF
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
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
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
Due to reduced margins, higher energy costs and rising atmospheric carbon dioxide (CO<sub>2</sub>) 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
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.
Industry Perspectives: The latest in refining technology
Nearly 700 refineries are operating in more than 120 countries around the world.
Global Project Data
<i>Hydrocarbon Processing</i>’s Construction Boxscore Database is tracking more than 1,700 active downstream construction projects around the world.
Diversification: The catalyst for the Middle East’s downstream transformation
Over the past several years, the Middle East has made substantial investments to increase its downstream processing capacity.
The next generation of advanced process control
In this article, Hydrocarbon Processing provides published references on model-based control, and contributing author Allan Kern presents his views on model-less control.
