The main technical specifications of liquid series ASPs
Raw air is sucked from atmosphere. After removing of the mechanical
impurity by air filter, it goes into the screw air compressor to be
compressed to 1.0Mpa. After being cooled and separated from the
water drops, it goes to the air precooler to be cooled to about 8
.0℃. It is separated from water drops through water separator for
removal of saturated water, carbon dioxide and some hydrocarbon
such as acetylene.
Purified air is cooled by the counter flow in the main heat
exchanger to saturated tempt., and part of them flows to the
rectifification column after being liquefied. After rectifying, the
liquid air is sucked from the bottom of the column and cooled in
subcooler and throttled to condenser-evaporator to evaporate as
cold resource. The nitrogen in the top of the column is evaporated
to condensation by liquid air. Most of the condensed liquid is used
as reflux, the rest of them flow to the liquid storage tank to
discharge regularly to the liquid storage tank out of the column.
To meet different demands from customers, different processes like
air cycle process ,nitrogen cycle process, high and low temperature
booster turbine expanding processor low temperature refrigerating
process etc. are adopted to reduce the power consumption. In order
to achieve stable and reliable operating of plant, PLC control
system or DCS control system are recommended.
We have supplied to many countries (Russia, Kazakhstan, Tajikistan,
India, Bangladesh, Thailand, Philippines, North Korea, Mongolia,
Equatorial Guinea, Botswana, Zambia, Angola, Tanzania) .
The design, selection of material, manufacture, inspection, and
test must be in accordance with the state standard and enterprise
specification and factory codes .
Quality certificate, inspection and test and records will be
provided by the manufactory(quality certificate for pressure vessel
will be given by pressure vessel supervision department).
