As a practicing engineer in the field of industrial gases for the past 65 years, 40 with L’Air Liquide, and another 25 as a private consultant on an international basis, I have encountered only seven textbooks worldwide compiled for our industry, even though the industry is over 100 years old. Of the seven, five were edited by university professors or academic research scientists. The sixth was written in 1989 by a process manager of an industrial company in England which almost filled the bill, but not quite. Those were published in England, one in France, two in the United States, and one in Russia. With the possible exception of the one on process cycles published in England, the rest were heavy on the theoretical side and did not serve the majority of the engineers’ need for applied technology.
