A huge growth in demand for lithium compounds is expected when automotive manufacturers start mass producing hybrid, plug-in hybrid and electric vehicles using lithium-ion batteries. In anticipation of the expanded business, many minerals-processing companies have been developing technologies for processing lithium from ores or brine into battery-grade (high-purity) lithium carbonate or lithium hydroxide...

New software tools address common issues, such as disorganized data and a streamlined workforce, through the use of simplified methods of presenting information, alerts and suggested actions. These tools are designed to increase human reliability and make chemical processing facilities safer and more reliable and more efficient.   Improving safety “One of the biggest issues for processors is...

Since the turn of the new millennium, considerable changes have been taking place in the methanol sector. About ten years ago, methanol plans in the U.S. were being shuttered, while new ones, with much larger capacity — the so-called mega-methanol plants, with capacities of 5,000 metric tons per day (m.t./d), were being constructed in regions of the world with abundant, inexpensive natural gas (Chem...

The word “sustainability” is used a lot, but for many businesses and industries it is increasingly becoming a challenge that must be taken seriously. As customers, large retailers and end-users continue to demand sustainable practices, packaging and products from their suppliers, chemical processors must start to change the way they package and deliver their goods, incorporating methods that...

In the ten years since its first isolation by a pair of Russian physicists, the single-atom-thick carbon allotrope known as graphene has been extolled as a “miracle material” for everything from television screens to tennis rackets to superabsorbent fabrics. What excites scientists so much about graphene is its myriad of impressive physical properties, some of which are illustrated in Figure 1...

When it comes to size reduction, chemical processors seek to improve product quality, increase flexibility and uptime and, simultaneously, reduce costs. Fortunately, equipment manufacturers are working to develop grinding, milling and screening machines that can help chemical processors meet their size-reduction needs. “Customers always want a better quality product, they always want to increase...

In the past, words such as “unproven,” “risky” and “expensive” may have come to mind when chemical processors considered wireless technology. However, today’s wireless solutions address these previously perceived limitations. In fact, wireless solutions are quickly becoming a must-have technology in the chemical processing environment because they provide a...

North American production of crude oil, driven by a rapid increase in output of “tight oil” from U.S. shale deposits like Bakken and Eagle Ford, is surging. In many, but not all areas, petroleum refiners are incorporating an increasing amount of this cost-advantaged feedstock into their crude-oil-processing slates to capitalize on its discounted price, which is partly a result of a lack of...

While air-sensitive materials may not be a part of every chemical process, certain catalysts, OLED (organic light-emitting diode) applications, inert gas welding, lithium-ion battery applications and other chemical processes do, indeed, require the inclusion of air-sensitive materials. And, when such materials are present at either research or mass-production scale, it can create an abundance of challenges...

"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 is no climate friendly scenario in the long run without CCS." So begins the 2013 edition of the Technology Roadmap — Carbon Capture...

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 them abundant, disposable and, in many cases, non-degradable. As landfill space decreases, and with some European...

The chemical processing industries (CPI) rely heavily upon the use of sensors to measure everything from weight to temperature to pH to pressure. Because sensors are used for measurements that affect critical processing elements, such as quality, efficiency and safety, it is important that sensors be placed almost everywhere in the facility, including in highly corrosive environments. Also, sensor readings...

In a culmination of more than three years of work by teams from across the globe, the International Organization for Standardization (ISO; Geneva, Switzerland; www.iso.org) on January 10 published the ISO 55000 series of standards surrounding asset management systems (AMS). The newly available standard can help companies in the chemical process industries (CPI) and other asset-intensive industries better...

Pressure to become more flexible and provide shorter cycle times have prompted chemical processors to examine their mixing operations to determine whether there is a way to increase process efficiency via mixing equipment. And, they just might be onto something, as modern mixing systems are designed for particular process requirements and mixing tasks, allowing them to operate efficiently. The greater...

Like most of the world, weighing instrumentation has gone digital and gotten connected. Not only do today’s scales, weight transmitters, check weighers, and other weighing equipment include more modern technological advances, but the up-to-date improvements also provide contemporary solutions for a lot of old-school weighing challenges.   Going digital While the main goals of weighing operations...

Propylene — one of the most important petrochemical feedstocks — has traditionally been supplied, together with ethylene, primarily from naphtha crackers. The recent exploitation of shale gas in North America is causing a shift to ethane cracking as a source for ethylene ( Chem. Eng., October 2012, pp. 17–19). As a result, petrochemical producers are scrambling to find alternative sources...

There is increasing interest in meeting the growing demand for generating power, fuels and chemicals by tapping into local resources. It not only reduces reliance on imported oil and gas, but also guarantees stable price development over the long term. One available solution, according to the experts, is the environmentally friendly gasification of carbon-containing fuels, such as coal, refinery residues...

When it comes to heat exchangers, chemical processors have a lot to consider. The most common concerns include fouling, heat-transfer efficiency, and the ability of the equipment to handle the high temperatures, high pressures and corrosive materials associated with the manufacturing of chemicals. And heat-exchanger manufacturers are continuously tweaking existing technologies to better suit the unique...
