On-Line Process Chromatographs Optimize Fine Chemicals Production

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.

In 1894 Linde starts with air liquefaction trials, followed by a patent for the so-called “Linde air” (a 50/50 mix of oxygen and nitrogen) in 1905. (Linde)
Milestones in Technical Gases

Setting the Pace: A Technology Pioneer Steps on the Gas

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 …
