They might be more expensive, but there’s probably no need to cancel your party plans just yet. “There’s lots of helium out there” says John Van Sloun, general manager — worldwide helium at Air Products, “but very little of it is being captured because the economics of doing so are not favorable.”

The Chemical Industry Phoenix

Process Automation Corner
Terry McMahon
Seven years ago, I wrote a column for another publica­ tion entitled “The U.S. Chemical Industry: R.I.P.” This pillar of American economic strength, which a few years earlier was the leading exporter among U.S. manufac­turing sectors (with net exports of $15–20 billion annually), was shriveling due in large part to policy blunders and regula­tory mistakes.
