Degasification system, liquid degasification method, degasification module, method for manufacturing degasification system, and method for producing natural resources

A method for manufacturing a degasification system comprising:

• preparing a plurality of degasification modules each having a hollow fiber membrane bundle having a plurality of hollow fiber membranes arranged around a liquid supply path through which a liquid is supplied and a module container which houses the hollow fiber membrane bundle and in which discharge ports for discharging the liquid are formed, and a connection supply pipe in which a plurality of openings through which the liquid passes are formed;
• inserting the connection supply pipe into the liquid supply paths of the plurality of degasification modules to connect the liquid supply paths of the plurality of degasification modules in series by the connection supply pipe and disposing the plurality of openings at positions corresponding to the plurality of degasification modules such that the liquid is supplied to the hollow fiber membrane bundles of the plurality of degasification modules in parallel;
• and
• in a case in which one of the plurality of degasification modules is designated as an upstream side degasification module, and one of the plurality of degasification modules disposed on a downstream side of the upstream side degasification module is designated as a downstream side degasification module, making a pressure loss of the liquid from a supply port of the connection supply pipe through which the liquid is supplied to the discharge ports of the downstream side degasification module larger than a pressure loss of the liquid from the supply port to the discharge ports of the upstream side degasification module.
