A thorough understanding of enclosed combustion technologies will help engineers to select the proper equipment to balance emissions-control performance with efficiency, costs and complexity Selection of an enclosed combustion solution is a complex process that involves various environmental and operational…
Last month, the American Chemistry Council (ACC; www.americanchemistry.com) issued its annual year-end report, which offers a positive outlook for the chemical process industries (CPI). The report, “Year-End 2017 Chemical Industry Situation and Outlook,” was prepared by the ACC’s Economics and…
A new collaboration between PPG (Pittsburgh, Pa.; www.ppg.com), SiNode Systems (Chicago, Ill.; www.sinodesystems.com) and Raymor Industries (Boirsbriand, Que., Canada; www.raymor.com) aims to accelerate commercialization for battery anodes made of a silicon-graphene composite. “These materials can achieve significantly higher capacities than…
3-D Printing At the 3-D printing tradeshow Formnext in November, GE Additive (Paris, France; www.ge.com) unveiled a laser-powder additive manufacturing machine with a 1-m3 build envelope. The machine, said to be the world’s largest laser-powder system, will be used to…
A counter-rotating propeller technology that is being developed to harness the energy from tidal currents has been field tested off the coast of Nagasaki Bay, near Iwo Jima, Japan. The prototype, which is one seventh the size of a commercial…
A new type of steam-reforming system that produces — in a single step — purified, compressed hydrogen from methane has been developed by a team of scientists from CoorsTek Membrane Sciences AS (Oslo; www.coorstek.com), the University of Oslo (both Norway;…
A team from the National University of Singapore (www.nus.edu.sg) led by professor Boon Siang Yeo has developed a prototype device that uses artificial photosynthesis to produce ethylene using only sunlight, water and CO2, at room temperature and pressure. The team…
Perovskite solar cells have attracted much interest in the past few years as the next-generation solar cells capable of surpassing silicon cells’ efficiency. However, because the perovskite materials are easily decomposed in moist conditions, they must be properly encapsulated, which…
Scientists from ExxonMobil (Irving, Tex.; www.exxonmobil.com) and the Institute of Chemical Technology (ITQ; Valencia, Spain; http://itq.upv-csic.es) have discovered a new material that could significantly reduce the amount of energy and emissions associated with the production of ethylene. Depending on the…
Photocatalytic reduction of CO2 into a fuel is an attractive way to reduce CO2 emissions into the atmosphere, and there are many projects underway around the world to find ways of converting CO2 into chemicals, such as H2, CH4, ethanol,…
