3.7 Solution penetration test.
The membrane module was the core equipment of the process. The
experimental instrument was arranged similar to the experimental
equipment used in MACC. The initial weight of the solution was recorded
with a precision electronic balance (Baoding Signal fluid Technology
Co.), and the heat exchange with the coolant is to be carried out. The
weight of the solution was measured every minute. In the solution
penetration test, it was found that the permeation of the two kinds of
membranes were both very small, which the mass transfer process was
ignorable. This result indicated the hypothesis that MACC possess only
heat transfer process was true.
