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

Propylene Carbonate in Trays using Absorber

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:

Shell and Tube heat Exchanger Simulation on Aspen hysys

Heat Exchanger 

Heat Exchanger Hot water at 500°C and 2000psig is used to heat cold stream of water in a shell and tube heat exchanger. The inlet temperature and pressure of the cold stream is 50°C and 260psig, respectively. The outlet temperature of the cold and hot streams are 300°C and 360°C, if the flow rate of the hot stream is 100kg/h, determine the flowrate of the cold stream passing throughout the exchanger

Design a shell and tube 

see the simulation design shell and tube using kerosene 42 API and crude oil 34 API   

The problem :

Design a shell and tube exchanger for the following duty 20,000 kg/h of kerosene (42 APO leaves the base of a kerosene side stripping column at 200°C and is to be cooled to 90°C by exchange with 70,000 kg/h light crude o (34 API) coming from storage at 40°C The kerosene enters the exchanger at a pressure of 5 br and the crude oil at 6.5 bar. A pressure drop of 0.8 bar is permissible on both streams Allowance should be made for fouling   factor of 0.0003 (W/m on the crude stream and 0.0002 (W/m C) on the kerosene stream.
