PROCESS DESCRIPTION - CONTINUED

The model used to describe the Simplified SSP was developed using JAVA and STASOFT 4 package. STASOFT 4 package is an aquatic chemistry calculation package that consists of two programs called STASOFT 4 and WATCHEM. STASOFT 4 can be used to model the Simplified SSP since gas recycling is not required. WATCHEM is a user input program. This model produces output that can be customized and imported into MSExcel for graphical representation. Multiple runs can be conducted using this program. The following variations can be used in a single run:

a) Varying the sidestream/mainstream blending ratios.
b) Stripping CO2 to the atmosphere before or after blending.
c) Operating with or without CO2 stripping.
d) Adding various buffers such as lime, sodium hydroxide and sodium carbonate.
