REACT program

In the program REACT, the procedure to model the initial fluid is... [Pg.321]

The Geochemist s Workbench Consider a dilute solution containing several ions in contact with the adsorbing surfaces of hydrous ferric oxide (HFO). A script for program react is shown in Table 7.2. [Pg.143]

Note that to model redox disequilibrium in phreeqc, a new species must be defined for each disequilibrium redox species (Parkhurst and Appelo, 1999, Example 15). Program react (The Geochemist s Workbench ) has a simpler decouple command. [Pg.170]

The Geochemist s Workbench In program react, part of The Geochemist s Workbench , equation (11.29) is implemented by using the kinetic command to set the variables (key words) required. The format is... [Pg.237]

This example is modified from one in the GWB User s Guide (Bethke, 1994). Program REACT in The Geochemist s Workbench also implements several other equations for rate laws, catalyzing and inhibiting species, nucleation, catalysis, and so on. [Pg.238]

The Geochemist s Workbench program react now includes procedures to calculate reaction kinetics of biotransformations, and the phreeqc documentation gives an example of similar calculations in phreeqc. [Pg.249]

Figure A. 1. Fractions of total As and Zn adsorbed onto hydrous ferric oxide (HFO) surface as a function of pH. Solid lines program react (The Geochemist s Workbench ). Dashed lines phreeqc.
In each case, we use program REACT and employ an extended form of the Debye-Hiickel equation for calculating species activity coefficients, as discussed in Chapter 7. In running REACT, you work interactively following the general procedure ... [Pg.79]

Following our convention, we place surface complexes to the left of the reactions and the uncomplexed sites to the right. For use with program REACT, file FeOH.data contains the database of surface complexation reactions prepared by Dzombak and Morel (1990). [Pg.131]

In the following sections we describe a prototype program, REACT, which is currently being, tested on a number of industrial problems. [Pg.92]

Tpfg = 5 X 1.0626 = 5.31 min Note Refer the MATLAB program react dsn cstr pfr.m... [Pg.147]

Thus, the space time x for CSTR is 6.4 times larger compared to that of PFR. Note Refer the MATLAB program react dsm opt temp.m... [Pg.183]

Note Refer the MATLAB program react dsn adiab2.m... [Pg.193]
