Workshop

      CSTR (Adiabatic vs Isothermal).

              A chemical reaction is going to be considered:

                  C3H6O + H2O→C3H6O2

                   Propylene Oxide + Water → Propylene glycol

                   Adiabatic operation:

                     - P = 3 bar

                      -V = 1000 L

                       

                     - FEED

Absorbed Statement / Hysys

                                                                                                              This lecture introduces the use of Aspen HYSYS to model continuous gas adsorption a process in a packed column The only unit process in the absorber is the tray section and the only streams are the upper steam and the lower liquid products .

                        

PROBLEM STATEMENT

CO2 is absorbed into propylene carbonate

in a packed column. The inlet gas stream

is 20 mol% CO2 and 80 mol% methane

The gas stream flows at a rate of 2 m³/s

and the column operates at 60°C and

60.1 atm. The inlet solvent flow is 2000

kmol/h. Determine the concentration of

CO₂ (mol%) in the exit gas stream, the

column height(m) and the column

diameter(m)

 

Absorber/ HYSYS

Design an absorber

 To absorb ammonia from an Air-Ammonia mixture containing the following molar compositions Using 98% molar concentration of H2504. Pure Air of appromiately 99% is desired at the top. (Hint: Pressure of Air-NH3=2atm, Temp. of Air-NH3= 136.5, Molar flowrate of Air-NH3= 123.6).

Absorbers

Absorbers bring gas and liquid phases in contact, so that contaminants in the gas phase absorb into the liquid phase as a result of their interaction.

 In this paper simulation of some process equipments were done by HYSYS , Equipment simulation is a basic work to design a chemical process plant. HYSYS is an easy and leading powerful process engineering simulation tool. Study shows the major advantages of the process simulator HYSYS over other simulation softwares and the causes of it’s preference. The equipments were chosen from typical downstream oil and gas process plants. This study involves the simulation of equipments such as heat exchangers, separators, vessels, distillation column, pumps, compressors, heaters and absorption tower.

Unit Operations in HYSYS - HYSYS Basic Course

Unit Operations 

Overview Integrated Steady State and Dynamics Simulation HYSYS uses an integrated steady state and dynamic modeling capability in which model can be evaluated from either perspective with full sharing of process information.

The components that comprise HYSYS provide a powerful approach to steady state process modeling. The comprehensive selection of operations and property methods lets you model a wide range of processes with confidence. Perhaps ever more important is how the HYSYS approach to modeling maximizes your return on simulation time through increased process understanding. The key to this is the Event Driven operation. By using a 'degrees of freedom approach, calculations in HYSYS are performed automatically. HYSYS performs calculations as soon as unit operations and property packages have enough required information
