DEGASIFICATION SYSTEM, LIQUID DEGASIFICATION METHOD, DEGASIFICATION MODULE, METHOD FOR MANUFACTURING DEGASIFICATION SYSTEM, AND METHOD FOR PRODUCING NATURAL RESOURCES

WIPO Patent Application WO/2020/067512

A1

This degasification system is provided with a degasification unit to which a plurality of degasification modules for degasifying a liquid are connected, wherein each of the degasification modules has a hollow fiber membrane bundle having a plurality of hollow fiber membranes arranged around a liquid supply path through which the liquid is supplied, and a module container which houses the hollow fiber membrane bundle. The degasification unit has a connection supply pipe serially connecting the liquid supply paths of the degasification modules and having openings which are formed at positions corresponding to the degasification modules and through which the liquid is passed so as to be supplied in parallel to the hollow fiber membrane bundles of the degasification modules, and the degasification unit is configured such that the pressure loss of the liquid from a supply port through which the liquid is supplied from the connection supply pipe, to the discharge port of a degasification module at the downstream side is larger than the pressure loss of the liquid from the supply port to the discharge port of a degasification module at the upstream side.
