Color Code for Material Stream

• royal blue

– Properly specified and completely solved

• light blue

– Incompletely specified, properties not solved

• Find specific volume of gaseous mixturedetermine the size and cost of plant

• HYSYS currently offer Peng-Robinson (PR) and Soave-Redlich-Kwong (SRK) equation of state

• PR supports the widest range of operating conditions and the greatest variety of system

• PR and SRK equation of state generate all required equilibrium and thermodynamics properties directly

• Ideal gas equation of state is adequate if P is low

• Since many chemical process takes place at high pressure, another equation was generalized , van der Waals equation of state

• Van der Waals however was not a good approximation at extremely high pressure operations, then the Redlich-Kwong (RK)equation was introduced

• Modification of RK equation by Soave then gives Soave-Redlich-Kwong(SRK) equation of state

• Another variation of RK equation is Peng-Robinson(PR) equation of state

• Reaction between water and propylene oxide to produce propylene glycol
