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...

CSIRO Minerals Down Under Flagship (Perth, Western Australia; www.csiro.au/MDU) has developed a method that uses hydrotalcite formation to simultaneously remove contaminants from mining and industrial wastewaters in a single step. Current wastewater-treatment processes typically produce lime-based slurries, often with large amounts of water, which requires additional treatment. In contrast, hydrotalcites...

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...

  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, which is usually generated during the use of carbodiimide agents. Thus, the new agent is...

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 Inc. (Grand Terrace, Calif.; www.wilden.com), and tradenamed the Pro-Flo Shift Air Distribution System, the...

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 the Chinese scientists, Zhaozhu Zhang, says that sponges previously developed to absorb oil from spills also soak up water as well, so...

To comply with increasingly stringent regulations for NOx emissions, operators of industrial plants often turn to low-NOx burners to avoid much more costly post-combustion treatment approaches like selective catalytic reduction (SCR). But low-NOx burners are plagued by significant losses in efficiency and process throughput. ClearSign Combustion Corp. (Seattle, Wash.; www.clearsign.com) has developed...

A process that uses magnetic nanoparticles, coated with a reactive material, to clean up contaminated water for human use is being developed at Stanford University (Stanford, Calif.; www.stanford.edu). The nanoscavengers, as they are called, are distributed in the water to kill pollutants, then are recovered magnetically for re-use. Stanford’s particles are...
