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.

The basic sealing task in mixing applications is to seal the rotating shaft as it passes through the vessel wall. Depending on the operating conditions — pressure, temperature, agitator speed, etc. — different types of seals are used. As this article shows, mechanical seals offer many advantages over other types of seals. Particularly if hazardous or explosive substances are being mixed, a mechanical seal is mandatory.

On a major part of the pump breakdowns in the Chemical Process Industry, the causes are NPSH problems, gas admixtures in the transported fluids, dry running or operating a pump outside the permitted range.

Since the company was founded in 1959, the clear objective of Vega Grieshaber has been the development of innovative and pioneering products for challenging measurements of level, point level and pressure. Particularly in the area of radar sensor technology for level measurements, almost the entire process engineering world looks to the company from the Black Forest for solutions.

Be it individual valves or entire valve islands, revolutionary flow meters or flexible platforms for networking — Bürkert Fluid Control Systems has been keeping media, processes and ideas flowing for over 70 years. How do they do that? At the company's headquarters in Ingelfingen, Germany, one is certain that the key to success is to make sure to never lose sight of the requirements of plant operators …

Ideas in technical gases don’t have to remain pipe dreams. When Carl von Linde invented his air separation process over a century ago, it marked the start of a success story that continues to this day. Technical gases revolutionized entire sectors, and continue to do so today. Just like Linde — the market leader in the gas industry who sets standards for these raw materials supplied in pressure cylinders …

Oil as a natural resource is becoming scarcer and more expensive and there is a need to look at eco-friendly ways of extracting it, thereby reducing CO2 emissions. White biotechnology offers a solution: scientists are now using microorganisms such as bacteria to generate substances for the production of polymers. The advantage is that these miniature biochemical factories run on renewable resources or agricultural waste converting it into valuable chemicals.
