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.…

A process that recovers rare-earth elements from ‘urban mining’

Electrochem Technologies & Materials Inc. (Montreal, Canada; www.electrochem-technologies.com) has recently patented a process for recovering rare-earth elements (REEs) from mercury phosphor powders — a byproduct from recyclers of fluorescent lamps and light bulbs. This technology offers a sound and profitable…

Install these rupture discs where atmospheric discharge occurs

The WMP (welded muffled plug) rupture-disc assembly is a single-use unit that is threaded into a pressure system. Designed to relieve the pressure of the process media in an overpressure condition, the unit protects equipment, personnel and the environment from…

Industrial Control Systems Security: The Owner-Operator’s Challenge

Ensuring the security of industrial control systems (ICS) can be a daunting and complex task, requiring expertise and experience in several areas from a variety of contributors. The rapid pace of improvements to both technology and practice adds to the…

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…

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…
