Claim 0:
1. A supply quantity adjustment method comprising the steps of:
a) calculating a total demand quantity used by at least one supply destination, based on plant information acquired from the at least one supply destination;
b) comparing the total demand quantity and a pre-set flow rate set value and setting a first calculated pressure value;
c) adjusting a backup coefficient set value based on a pre-set supply-destination reference gasholder pressure, the first calculated pressure value, a pre-set reference backup pressure set value, and a measured gasholder pressure value, which is a measured pressure value of the supply-destination gasholder; and
d) adjusting a production coefficient by comparing a production pressure set value obtained by adding the pre-set supply destination reference gasholder pressure and a first pressure output value with the measured gasholder pressure value; and
e) modifying a variation in product gas production quantity by an at least one air separation apparatus based on the production coefficient adjusted in step d).
