North American production of crude oil, driven by a rapid increase in output of “tight oil” from U.S. shale deposits like Bakken and Eagle Ford, is surging. In many, but not all areas, petroleum refiners are incorporating an increasing amount of this cost-advantaged feedstock into their crude-oil-processing slates to capitalize on its discounted price, which is partly a result of a lack of...

The petroleum refining sector in India plays a vital role in the country’s industrial development and provides a major source to meet India’s energy requirements. Today, the refining sector satisfies about 30% of the total energy demand of India [ 1]. As of April 1, 2013, the total installed capacity of Indian refineries was 215 million metric tons per year (million m.t./yr), of which 80...

Sapphire Energy, Inc. (San Diego, Calif.; and The Linde Group (Munich; have signed an agreement, with a minimum span of five years, to commercialize Sapphire’s process for producing crude oil from algae. The agreement expands an existing partnership in which the two companies have developed a low-cost method for delivering CO2 to algae ponds. Linde will now help...

A typical fluid catalytic cracking unit (FCC) generates about 200 tons/d of dry gas — a mixture of off-gases that is burned as refinery fuel. However, about 40 tons of that gas is ethylene, which would have much greater value as gasoline or diesel fuel. A process that converts better than 40% of the ethylene to motor fuels in a single pass is being developed by UOP LLC, a Honeywell...

JX Nippon Oil & Energy Corp. (JX_NOE; Tokyo, Japan; has demonstrated enhanced propylene and butenes yields by its high-severity, fluid-catalytic cracking (HS-FCC) technology. In a 3,000-bbl/d semi-commercial plant, which has been operating at the company’s Mizushima Refinery since May 2011, propylene yields have been...

What is said to be the world’s first commercial alkylation plant to use a solid acid catalyst is scheduled for startup early next year by Shandong Wonfull Petrochemical Group Co. (Zibo, China). The plant, which will produce 100,000 ton/yr of alkylate, will use a process called AlkyClean, developed by CB&Is Technology Group (The Woodlands, Tex.;, Albemarle Corp. (Orangeburg, S.C....

An improved H2SO4 process developed by CB&I (The Woodlands, Tex.; has now been licensed to three companies, all in China. The first licensee was Ningbo Haiyue New Material Co. Ltd., which is building a 600,000-m.t./yr plant near Ningbo City, Zhejiang Province (CE, December 2011, p. 11). The other two plants, each of 200,000 m.t./yr, are being built by undisclosed companies in Shandong and...

The volume of heavy, sour crude oil processed by North American refineries is steadily increasing, and along with it a commensurate demand for hydrogen to upgrade that oil. A steam-reforming process that would allow refiners to produce their own H2 from heavy oil and residuum is being developed by TDA Research, Inc. (Wheat Ridge, Colo.; Currently, refiners make a lot of their own hydrogen by...

Aither Chemicals LLC (South Charleston, W.Va.; is planning to build a commercial-scale plant based on a catalytic ethane-cracking process that uses 80% less energy and generates 60% less carbon dioxide than conventional steam-cracking of ethane.  The company has refined a mixed metal-oxide catalyst that was originally developed by Union Carbide in the 1980s. The catalyst...

A variety of performance problems can arise in distillation towers during startup. Many are caused by equipment, hardware or process conditions. Hardware issues may be related to instrumentation, tower internals or ancillaries. Instrumentation malfunctions are also common during startup and are predominantly related to liquid level indicators, online analysis of key components and in some cases...

A Samsung petrochemicals facility in South Korea will be the first to feature a suite of energy efficiency technologies developed by UOP LLC (Des Plaines, Ill., for improved aromatics production. A number of UOP aromatics-processing design features and materials will be integrated to allow the facility to reduce its energy consumption by 33%. The facility will produce 1 million m.t./yr of para...

A proprietary nanoscale catalyst and an updated engineering design have allowed higher conversion rates for transforming the heaviest fractions of crude oil, known as vacuum residue, into high-value transportation fuels, such as diesel. Developed by UOP LLC (Des Plaines, Ill.; and called Uniflex, the technology combines elements of the CANMET hydrocracking process used by Petro-Canada from...

Venezuela’s state-run petroleum company, PDVSA Petroleo, S.A. (PDVSA, Caracas;, will commercialize a company-developed process for upgrading heavy crude oil in its Puerto La Cruz refinery, about 300 km (190 miles) east of Caracas. The 210,000-bbl/d plant will employ PDVSA’s HDH Plus process (for hydrocracking...

An improved sulfuric-acid alkylation process that reduces acid consumption by up to 50% from that of conventional processes will make its commercial debut in China. Developed by Lummus Technology, a CB&I company (The Woodlands, Tex.;, the technology will be used by Ningbo Haiyue New Material Co. in a grassroots alkylation plant to be built near Ningbo City, Zhejiang Province. Scheduled for...

Anew process to make BTX (benzene, toluene and xylenes) from light cycle oil (LCO), an oversupplied product of petroleum refineries that can supplement the dwindling supply of BTX precursors, is being developed by JX Nippon Oil & Energy (JX Energy; Tokyo, Japan; Whereas conventional technology requires...

Today only a few percent of Canada’s oil sands resource is accessible by traditional surface mining, so the rest has to be recovered in situ, mostly by steam-assisted gravity drainage (SAGD). In this process, steam is injected into a horizontal well in the oil formation to mobilize the viscous bitumen, which is recovered by a producer well at a lower level. An in-situ process that promises to be more...

An Australian team including CSIRO (Melbourne; and the Uni- versity of Newcastle ( has developed an alternative pathway for producing ultra-low-ash coal that, the team believes, can be used to fuel diesel engines, thus providing the opportunity for diesel engines to replace steam engines for large-scale base-load power generation. The method involves slurrying and...

By the end of this year, Asahi Kasei Chemicals Corp. (Tokyo; plans to complete development on two processes that utilize excess C2 and C4 fractions for producing propylene and butadiene, and if all goes smoothly, implement them by March 2012. The company has been developing its so-called E-Flex (for producing propylene) and BB-Flex (for producing butadiene) processes, and is now...

Strategies for extracting more distillate from petroleum to meet the growing demand for diesel fuel constituted a major theme of the recent annual meeting of the National Petrochemical and Petroleum Refiners Association (NPRA, Washington D.C.; in San Antonio, Tex. Worldwide, the demand for distillate is expected to increase by more than 5 million bbl/d over the next 10 years, says Richard...
