What if we could make the Great Pacific Garbage Patch just disappear? What if plastics didn’t accumulate in our landfills? What if we could reduce greenhouse gas emissions while replacing up to 30% of the world’s plastics with a biodegradable substitute? Researchers have tried for decades to achieve these goals. One approach being taken is the development of an efficient production process for poly-hydroxyalkanoate (PHA) — a biodegradable polymer similar to the polypropylene used to make yogurt containers.
The role of natural gas for electricity generation is expanding, as utilities take advantage of the low cost and lower emissions of natural gas, as well as the ability of natural-gas-based systems to provide on-demand power during periods of peak consumption.
The largest, fully integrated process for separating CO2 from fluegas and compressing it to a supercritical fluid, transporting the CO2 by pipeline, and injecting the CO2 into a saline reservoir is now underway at the Plant Barry generating station...
Carbon dioxide emissions pose a significant global threat. According to the United Nations Intergovernmental Panel on Climate Change (IPCC), atmospheric concentrations of CO 2 -equivalent must be limited to 450 ppm by 2100 to limit the global...
Plentiful, low-cost natural gas will invigorate the chemicals industry over the next decade, as producers look to increase the role of natural gas as a feedstock in established processes, as well as develop new processes to convert methane into chemicals currently derived from petroleum.
At about 5:30 a.m. on Nov. 19, 1984, there was a major fire and a series of explosions at a liquefied petroleum gas (LPG) storage and distribution terminal at San Juan Ixhuatepec, Mexico City, Mexico. There were over 500 fatalities, about 7,000 injuries, 200,000 people were evacuated, and the terminal was destroyed. The blasts were recorded on a seismometer 20 km (12.4 miles) away. Most of the injuries and fatalities were in the surrounding community — people were living as close as 130 m (425 ft) from the terminal. The cause of the accident could not be definitively established because of the destruction of the facilities and absence of witness reports.
The recent development of new sources of shale-gas methane and shale-gas condensate will significantly impact fuels and chemical feedstocks in the U.S. and around the world, says Jeffrey Siirola of Purdue Univ. and Carnegie Mellon Univ. in the March AIChE Journal Perspective article, “The Impact of Shale Gas in the Chemical Industry.”
The capture of CO2 from flue- and fuel-gas streams in large-scale power generation offers a compelling means to combat climate change. Technically plausible strategies for CO2 capture include post-combustion carbon capture (PCC), oxy-combustion, and...

Carbon capture and storage (CCS) could be an important part of the transition to lower-carbon energy sources. However, widespread integration of CCS with existing power-generation plants and technologies — on a commercial scale and in a cost-...
A legal framework governing carbon sequestration will need to be put in place before major carbon capture and storage (CCS) projects can get underway. A final rule issued under the Safe Drinking Water Act sets minimum requirements, but this is just...
The beneﬁcial microbes that convert milk into yogurt and act in our guts to promote digestive health cause big problems in ethanol fermentation tanks. These lactic acid bacteria (LAB) proliferate in ethanol feedstock and inhibit growth of ethanol-producing yeast — which slows down fermentation, reduces biofuel yield by as much as 20% per pound of input material, and results in production shutdowns due to contamination. The most common control measures, chemical antimicrobials such as antibiotics, do not eliminate LAB. Additionally, the potential for antibiotic residue limits the marketability of dried distillers grains, a byproduct of the fermentation process used as animal feed. Ecolyse Inc., based in College Station, TX, is working to address this issue by developing products to treat bacterial contamination.
If your facility has an upcoming energy assessment, you might be overwhelmed with the list of things you need to do, data you need to organize, and people you need to contact. This article streamlines the planning process and recommends steps you can take to optimize your facility’s energy costs.
The AIChE Annual Meeting is the premier educational forum for chemical engineers interested in innovation and professional growth. Academic and industry experts will cover wide range of topics relevant to cutting-edge research, new technologies, and emerging growth areas in chemical engineering.
