Keep areas clean with these vacuum cleaners

In addition to large amounts of conventional dust, the new IVS 100 range of industrial vacuums (photo) also pick up hazardous, as well as combustible dust and coarse particles. The particles are vacuumed directly where they are generated and therefore…

A smart system gets the compressor lubrication right

The XperLUBE system (photo) uses automotive-style solenoid injectors to deliver lubricant in precise quantities. Unlike traditional lubrication devices, XperLUBE integrates fully with modern control systems and adapts to changes in operating conditions. A key feature is the way each injector…

The launch of a new metering system

Launched last month at Weftec (Chicago; October 2–4), the new Bravo chemical metering system provides improved process control with reliable, accurate and repeatable flow, and reduced chemical consumption, says the company. Bravo is an integrated, modular and scalable solution used…

Controlled sifting of bulk materials

The Contromat VE 450 (photo) and VE 630 (which is square shaped) handle sifting capacities between 0.15 and 0.3 m². Previously, the Contromat had been delivered without an outlet for foreign particles, which remained on the sieve and had to…

Physical and cybersecurity: Protect Your Plant

Both physical security and cybersecurity must be in place to keep chemical facilities safe from attack While almost all businesses in today’s world are concerned with security — both physical security and cybersecurity — chemical processors likely have a deeper…

Extending Membranes’ Reach Across the CPI

Advances in next-generation materials and assembly techniques have enhanced membranes’ effectiveness in numerous applications Membranes are one of the primary technologies used for separations. While they may be best known for their use in water-treatment operations, advances in membrane technologies…

Lower costs for converting alkylation units from hydrofluoric to sulfuric acid

For petroleum refineries, the cost of converting hydrofluoric-acid-based alkylation units to the relatively safer sulfuric-acid-based alkylation process (diagram) has been cost-prohibitive and has lacked specific economic benefits. Now, DuPont (Wilmington, Del.; www.dupont.com) has developed a low-cost approach to converting existing…

Multilayer membrane for climate control

A triple-layer, porous membrane system developed at the Functional Materials Laboratory at Eidgenössische Technische Hochschule Zürich (www.fml.ethz.ch) can be fashioned into evaporative curtains to cool and humidify indoor spaces, potentially decreasing the energy demand for climate-control systems. Juxtaposing opposite forces…
