Nowadays, the most common way to obtain extremely fine particles from suspensions is a combination of spray drying followed by a subsequent grinding process. The grinding step is necessary because the product from a spray dryer is in the form of an agglomerate. To avoid the need for this two-step process and so reduce equipment costs, Nara has developed a different type of dryer.

Filtration centrifuges provide a good method for mechanically separating suspended solids from liquids. Separation in a centrifugal field generated by equipment rotating at high speed has a number of advantages compared to simple vacuum and pressure based techniques.

It is essential to select the right equipment in order to achieve reliable results when measuring humidity. The same is true of calibration processes which are carried out at regular intervals and should be based on traceable standards. This will serve to guarantee reliable results in the long term.

When talking today about solid dosage form production, often containment immediately becomes one of the issues. Why?

For the third time PROCESS chose the best product innovations in the industry at this year’s Powtech/TechnoPharm trade fair in Nuremberg/Germany. The judging panel selected the best entries from more than 50 nominations and presented awards in a prize-giving ceremony.

Italvacuum has manufactured vacuum pumps and vacuum dryers for the chemical and pharmaceutical industries since its establishment in 1939. The company supplies turnkey systems and bespoke equipment built to suit its customers’ needs.

Petroleo Brasileiro (Petrobras), Latin America’s largest company and one of the world’s largest oil producers, is turning to Sandvik’s Rotoform solidification technology to handle the increasing volumes of sulphur produced at its Brazil refineries.

Exact and reliable chemical analysis of feedstocks and products is very important in the manufacture of fine chemicals. Laboratory gas chromatographs are among the techniques traditionally used for this task, but pressure to improve process operations has brought change. Online process gas chromatography now provides significant benefits, as shown on a naphtha cracker.

Radar level measuring instruments have written a success story. The areas of application were gradually extended. However, according to the unanimous opinion of the experts, a measuring instrument that really covers all applications had not yet been sighted. Thanks to the higher frequency ranges and new instrument versions, a new instrument comes very close to this ideal.

Without the presence of “nothing,” literally nothing goes in many chemical processes. Whether for vaporization, sublimation, rectification, filtration, drying or conveying: Vacuum accelerates these process steps or is required to make them possible in the first place. Pfeiffer Vacuum has embodied a fascination for vacuum technology and its possibilities for more than 125 years.
