The book is about the technology and applications of industrial gases from oxygen and argon to silane and arsenic trihydride (not natural gas / methane). Here is what an independent reviewer said: "I started to read the book from the beginning and found that I was enjoying it. In the end, I realized that for the first time in my life I had read a text book from cover to cover... The style is relaxed and the contents meander gently through most aspects of industrial gases production and use. I recommend this book to anybody who is interested in the subject. Even experienced practitioners tend to be specialized in one part of the field and this book offers the chance to find out what colleagues really do. Readers need only a modest technical ability, making this book particularly useful for those in commercial financial and managerial careers.“ Keith Guy, Chemistry in Britain
