In hydraulic fracturing, high-pressure pumps force water bearing sand or ceramic proppants into a manifold, known as a missile, and subsequently into an oil or gas well. Exposure to the highly abrasive, proppant-filled fluids means the pumps require frequent maintenance…
To meet the needs of the chemical process industries, new valve materials and designs combat corrosion and leaks In the grand scheme of any chemical process, a valve might seem an afterthought. However, in reality, valves play as critical a…
A new low-pressure xylenes-production process combines toluene with methanol to yield a xylenes product stream with the possibility of no benzene byproduct. Known as GT-TolAlk and developed by GTC Technology (Houston; www.gtctech.com), the new process requires no hydrogen addition and…
Plant Watch Dresser-Rand, Ener-Core to provide cogeneration system to Pacific Ethanol January 12, 2015 — Dresser-Rand (Houston; www.dresser-rand.com) will install a 3.5-MW cogeneration system at Pacific Ethanol Inc.’s (Sacramento, Calif.; www.pacificethanol.com) ethanol-production plant in Stockton, Calif.

The Catalyst Div. of BASF (Iselin, N.J.; www.basf.com) has launched PremAir NXT, a next-generation direct ozone reduction (DOR) catalytic coating technology that can help automakers meet new U.S. Tier 3 and California LEV III emissions reduction requirements. When applied to…
The hydrothermal liquefaction of algae has been the subject of many studies because algae exhibit high photosynthetic activity and growth rate compared to other biomass, leading to increased CO2 absorption. The algae can grow in a wide variety of water…
Mechanical engineering students have been taught that true isothermal compression, while ideal from an energy-efficiency perspective, is not achievable. However, a late 1800s technology, the Taylor Compressor has delivered isothermal compression in large industrial applications for nearly a century. The…
Adipic acid, a precursor for the synthesis of nylon, is usually produced through nitric acid oxidation of cyclohexane, a process which has disadvantages, such as the emission of nitrous oxide — a greenhouse and ozone-depleting gas — as well as…
A specially designed electrode could improve the efficiency of removing suspended solids, oil or other contaminants from water in applications traditionally served by dissolved-air flotation (DAF). Developers at OriginOil Inc. (Los Angeles, Calif.; www.originoil.com) believe their electrolysis process overcomes limitations…
At the European Coatings Show (April 21–23; Nuremberg, Germany), Bayer MaterialScience AG (BMS; Leverkusen, Germany; www.materialscience.bayer.com) will launch Pentamethylene diisocyanate (PDI), a new isocyanate with 70% of its carbon content originating from biomass. The eco-friendly hardner component is being evaluated…
