Table 27 Primary Variables of EWASG

Phase Conditions	PrV1	PrV2	PrV3	PrV4	PrV5	PrV6	PrV7	PrV8	PrV9	PrV10
Gas	Pg	Xg1	Xg2	Xg3	Xg4	Xs1	Xs2	Xs3	Xs4	T
Aqueous	Pa	Xg1	Xg2	Xg3	Xg4	Xs1	Xs2	Xs3	Xs4	T
Two-Phase	Pg	Sg+10	Xg2_G	Xg3_G	Xg4_G	Xs1	Xs2	Xs3	Xs4	T

Table 27 shows the parameters of default initial conditions for EWASG. In the table, Pg and Pa are pressure for gas and aqueous phase respectively. T is temperature. Xgn is the gas n mass fraction in the existing phase. Xgn_G is the gas n mass fraction in the gas phase excluding water vapor. Xsn is salt n mass fraction in aqueous phase or in solid phase if no existence of aqueous phase. If Xs1>10.0, it will be the solid salt saturation plus 10.0.

Xg2-Xg4, Xs2-Xs4 are optional. They are required only when the corresponding component exists in the model.
