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
P = 3 bar, T = 24°C
8.7 C3H60, 300 H2O (kmol/h)
- Kinetic Data
- K = 9.2E22
- Ea= 1.56E8 J/kmol

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.
Shell & Tube Heat Exchanger Design with ASPEN HYSYS
How does the heat exchanger is work in the HYSYS program?, we have already talked about that, but we will explain more in this video simulation design heat exchanger.
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
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
ABSORBER
Carbon dioxide is absorbed into propylene carbonate in trays. The inlet gas stream is 23mol% CO2 and 77 mol% methane. The gas stream flows the rate of 100kgmole/hr and the column operates at 59 degree C and 60atm. The inlet solvent flow is 100kgmol/h at 100% composition Determine the concentration of each component in the outlet streams (mol%) Property:
Cooling gas production
How is cooling gas production in oil fields , and what is required for associated dewatering , add to that what are the facilities required.
