Summary
-
1.
A directed flow graph method has been used to set up a mathematical description of a process, calculating all optimal values of material and heat parameters of the process.
-
2.
The required consumptions of water, fuel, and steam have been calculated for optimal processing, which opens up the possibility of a 25% increase in the yield of desired product (with residual feedstock).
-
3.
It has been noted that variations in the amount of feedstock supplied to the extraction tower have little influence on the operation of the coolers or heaters in this process flow plan.
