In recent years, engineers at ETH Zurich have developed technology to produce liquid fuels from sunlight and air. At the heart of the production process is a solar reactor that is exposed to concentrated sunlight delivered by a parabolic mirror…
Now in its 27th year, the Green Chemistry Challenge Awards recognize and promote chemical technologies that reduce hazards to people and the environment by incorporating the principles of green chemistry into chemical design, manufacture and use. The program is sponsored…
With new manufacturing improvements to its standard plated paddle agitator (photo), this company can speed up lead times on its 30-in. dia. and smaller-sized horizontal mixers. The new plated paddle agitators are manufactured with the paddle and arm sections cut…
Within rubber production facilities, density is an important process parameter that correlates with the degree of cross-linking or the hardness of the elastomer used. The determination of the density is therefore of great importance for the development of recipes and…
In traditional beer brewing, the progress of the fermentation process is typically checked manually, by inserting a hydrometer (beer spindle) that measures the density, from which the extract content of the wort can be derived — a procedure that not…
Leather Tanning Trumpler GmbH & Co. KG (Worms, Germany; www.trumpler.com) and Archroma (Pratteln, Switzerland; www.archroma.com) have developed a new leather-production process that can be used to produce high-performance leather in a more eco-friendly and cost-efficient way. The new process, DyTan,…
The Mobile Minor MM 100 spray dryer (photo) is equipped with the Cyclone CEE mechanical powder separator. This cyclone helps operators overcome challenges in spray drying, such as smearing due to powder settling in the cyclone, as well as abrasion…
Adhering to API 682 guidelines will create safe, efficient and effective mechanical-seal supports in pumping systems In the 1980s, mechanical seals became the most frequently used sealing technology in petroleum refineries and chemical plants. The American Petroleum Institute (API; Washington,…
A practical overview on how to use location factors, and some tips on when to use — or not use — them Often in the early stages of project development in the chemical process industries (CPI), the development team is…
As various rotating machinery throughout fiber-processing operations experience extremely harsh and demanding environments, it is often difficult to manually retrieve oil samples. Maintaining an adequate surveillance of lubrication properties against harmful effects can prove very challenging. This company’s oil-monitoring system…
