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…
Anti-hydrolysis agent Teijin Ltd. (Tokyo, Japan; www.teijin.co.jp) has developed a new carbodiimide anti-hydrolysis agent that is said to exhibit “superior” anti-hydrolysis properties to improve the durability of plastics. The agent has the additional advantage of not emitting isocyanate gas,…
JX Nippon Oil & Energy Corp. (JX_NOE; Tokyo, Japan; www.noe.jx-group.co.jp) 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…
New technology developed for air-operated, double-diaphragm (AODD) pumps can reduce consumption of compressed air by up to 60% without electronic components, while maintaining the same flowrates. The reduced air consumption translates directly to lower energy usage. Developed by Wilden Pump…
Scientists from the Chinese Academy of Sciences (Beijing; www.cas.ac.cn) have found a way to transform polyurethane (PU) foam into a sponge that is strongly water-repellent and oil-absorbing, making it suitable for soaking up chemicals and petroleum from spills. One of…
Japanese researchers from the New Energy and Industrial Technology Development Organization (NEDO; Kawasaki City; www.nedo.go.jp), Waseda University, JX Nippon Oil & Energy Corp. (JX_NOE) and five other companies along with five more universities have developed an inorganic membrane that enables…
Technology originally developed for harvesting oil from algae has now been applied to sanitize water and remove ammonia from commercial aquaculture ponds. Electro Water Separation (EWS) technology, developed by OriginOil Technologies (Los Angeles, Calif.; www.originoil.com), applies pulses of tuned electromagnetic…
NEDO and Hitachi Ltd. (Tokyo, www.hitachi.com) have developed a new combustion technology that could reduce the emissions of oxides of nitrogen (NOx) to below 10 ppm without the addition of diluents. As part of the CCS-IGCC project (carbon capture and…
ODC for Cl2 production Last month, ThyssenKrupp Uhde GmbH (Dortmund; www.uhde.eu) and Bayer MaterialScience AG (BMS; Leverkusen, both Germany; www.bayermaterialscience.com) commercially launched — worldwide — the oxygen depolarized cathode (ODC) technology, which BMS and ThyssenKrupp Uhde/UhdeNora developed to improve…
In April development tests, Cobalt Technologies (Cobalt; Mountain View, Calif; www.cobalttech.com) produced n -butanol at the fermentation scale of 100 m3 per run, demonstrating lower production cost than butanol produced from petroleum. This represents production that is a factor of…
