OSTI ID:6480869
The EQ3/6 version .2055U software computes thermodynamic equilibrium models for aqueous solution-mineral systems. It consists of two main programs, EQ3 and EQ6. EQ3 performs distribution-of-species calculations for natural water compositions; EQ6 uses the results of EQ3 to predict the consequences of heating and cooling aqueous solutions and of irreversible reaction in rock-water systems. The programs can be used to study such phenomena as the formation of ore bodies, scaling and plugging in geothermal development, and the long-term disposal of nuclear waste.CDC7600;CRAY1; FORTRAN Extended 4.6 (CDC7600) and CFT (CRAY1); SCOPE 2 (CDC7600); About 45,000 (octal) words of SCM and 58,000 (octal) words of LCM are required on a CDC7600 for EQ3, about 125,000 (octal) words of SCM and 32,000 (octal) words of LCM for EQ6. Four units in addition to the standard input/output units are used by EQ3, ten units in addition to the standard I/O units by EQ6.
