Reduce energy costs by combining wastewater treatment and desalination

New Energy and Industrial Technology Development Organization (NEDO; Kawasaki, Japan; www.nedo.go.jp) and Global Water Recycling and Reuse Solution Technology Research Assn. (GWSTA) have developed a new water-treatment system that integrates seawater desalination with recycle water from a sewage treatment plant.…

Covered lagoons treat wastewater and make biogas, too

The world’s first installation of the so-called Cohral technology — deploying a covered lagoon for anaerobic wastewater treatment — was completed last March at Oakey Abattoir Pty Ltd. in the farming region of Darling Downs, in southern Queensland, Australia. The…

Piping-System Leak Detection and Monitoring for the CPI

Leaks in a chemical process industries (CPI) facility can run the gamut from creating a costly waste to prefacing a catastrophic failure.. They can be an annoyance, by creating pools of liquid on concrete that can become a possible slipping…

Fired Heaters: Best Practices for the Control of Fuel Gas

Large petroleum-refining complexes often have dozens of fired heaters, making broad-based competency in this area essential to overall reliability, safety and energy efficiency. Despite industry’s widespread familiarity with fired heaters, they continue to pose significant challenges during initial control-system design…

A promising process to recover Li from seawater

Lithium is an element of growing importance for the production of batteries and nuclear fuels. Because Japan relies completely on imports of this material, with the majority coming from South America, the country is looking for alternative sources for this…

Cybersecurity: The challenges of interconnectivity

Big-time security threats and breaches, like the recent Target data breach involving confidential consumer information, remind us of how vulnerable our interconnectivity makes us. And yet, the advantages of the technological advances that we enjoy are so many that there…

Imitating nature leads to a separator for oil droplets

Separation of micron-sized oil droplets from water is difficult by conventional methods. A Chinese team has developed an oleophilic array of conical needle structures that can continuously collect micron-sized oil droplets from an oil-water mixture with high efficiency and high…

CO2 gets Grounded

"As long as fossil fuels and carbon-intensive industries play dominant roles in our economies, carbon capture and storage (CCS) will remain a critical greenhouse gas reduction solution. With coal and other fossil fuels remaining dominant in the fuel mix, there…

Static Electricity Discharge and Fire Prevention

When flammable or combustible atmospheres are present, uncontrolled discharges of static electricity are potentially dangerous or even catastrophic. A significant portion of industrial explosions and fires are attributable to static electricity each year. In theory, controlling static electricity by grounding…

Advanced Polymer Recycling

Polymers like polyethylene, polypropylene, polyvinyl chloride and polyester have become ubiquitous in manufacturing. The properties of polymer-based materials that make them so desirable — they are generally cheap to produce and boast high chemical and thermal stability — also make…
