Abstract:
Most of oxygen being consumed today
in Japan, is produced by the cryogenic
air separation process which is
represented by the name of "Linde process".
The cryogenic process has been in
use over 70 years but cryogenic process
plant is an elaborate and complex plant
to operate. Because it is operated under
high pressure which requires a supervisory
engineer and skilled labours.
Oxygen produced in a large oxygen
plant of the cryogenic process is usually
transported either in heavy steel cylinders
in gaseous state or by tank lorry
trucks in liquid state. The transport of
oxygen by these vessels to consumers
for a long distance is not only troublesome
but it makes the oxygen price very
expensive.
