The work content on the low temperature side is work on the high temperature side 3.3 After
completing vacuum evacuation, work to enclose pentane is added. After that, work from the work
of vacuum evacuation
②
in the same procedure as the high temperature side.
Describe additional pentane inclusion work below.
4.7 Enclosed in pentane
4.7.1 Pentane collection
Preparation
:
Pentane charging cylinder, n-pentane, pentane dryer, explosion-proof
vacuum pump, charge hose, branching instrument, tool
Procedure1 : Prepare the pentane, reconfirm the enclosed amount and convert the "weight
⇒
scale" using the conversion table.
Attach a pentane dryer to the tip of the valve VCL of the pentane cylinder and
connect the tip of the valve VCU to the vacuum pump with a charge hose. (At
this time, VCU is "open", VCL is "shut" state)
Operate the vacuum pump and evacuate it to a state where pentane solution
can be injected. (About 1 minute)
Note1
:
Because pentane vapor is generated, use an explosion-proof vacuum pump.
The pentane dryer has the function of removing the same moisture as the
dehydrator.
