Absorbed Statement / Hysys



                                                                                                              This lecture introduces the use of Aspen HYSYS

 to model continuous gas adsorption 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 .

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)

? how could use hysys to solve the problem  


If you have Oil Manager checks as part of a HYSYS case, you can easily convert them to the updated HYSYS Petroleum Refining format and use them in cases.

1. In the Properties environment, in the navigation pane, select Petroleum
Assays.
2. On the Home ribbon tab | Oil group, select Convert to Refining Assay.
3. On the Oil to Assay Manager Conversion dialog box, select on of the
following options for the Fluid Package:

> use existing

Petroleum Assay


A crude oil assay

   

is the chemical evaluation of crude oil feed   stocks by

 

petroleum testing laboratories. Each crude oil type has unique.

  

molecular and chemical characteristics. no two crude oil types

 

are identical and there are crucial differences in crude oil quality.

 

the results of crude oil ssat testing provide extensive detailed

 

hydrocarbon analysis data for refiners ,oil traders and producers

 

 assay data help refineries determine if a crude oil feedstock is

 

comp a particuular  petroleum refinery or the crude oil could

 

.cause yield

Crude Oil Pre Heat simulation

 



Problem Statement Cont.


A crude stream at 15°C, 1000 kPa and flowrate of 6x105 kg/hr is

 mixed with a stream of water at 15°C, 1000 kPa and flowrate of

 21600 kg/hr using a Mixer, the outlet from the mixer is then

heated to 65°C through a Heater (Ap=50 kPa),the heater outlet is

 feed to the tube side of a Shell & Tube Heat Exchanger, where it's

 heated using a Shell inlet stream having the same composition as the

 crude feed stream and enters the shell of the heat exchanger at

 180°C, 200 kPa and flowrate of 175m³/hr.

                                                           

The liquid product from the separator is then heated to 400°C inside a Heater (Pressure drop-250 kPa) before entering the Atmospheric Column.

Heat Exchanger Specification:
Use Simple weighted model

- The Shell side outlet Temperature is 95°C

Calculate:

-The vapor fraction of the product stream before
entering the atmospheric column.

Min Approach; This is the minimum temperature difference between

 the hot and the cold stream. The vapor molar flow rate from the 
 Pre-Flash.

The pressure drops for the Tube and Shell sides, will be 35 kPa and 5

 kPa, respectively. The tube outlet from the Heat Exchanger is

then sent to a desalter which is simply modeled as Three Phase

 Separator where desalted water, oil and gas is separated.

The oil stream (light liquid) from the desalter is then heated to 175°C

 through a Heater (Pressure drop=375 kPa) and then sent to a Pre

 flash (Separator) to reduce the light components in the feed.

The petroleum characterization



Introduction

The petroleum characterization method in HYSYS will convert laboratory analyses of condensates, crude oils, petroleum cuts and
coal-tar liquids into a series of discrete hypothetical components
These petroleum hypo components provide the basis for the property package to predict the remaining thermodynamic and
.transport properties necessary for fluid modelling 

Assay

The assay contains all of the petroleum laboratory data, boiling
point curves, light ends, property curves and bulk properties. 
HYSYS uses the supplied Assay data to generate internal TBP, molecular weight, density and viscosity curves, referred to as Working Curves.


Problem Statement 

With the aid of the Oil Characterization option in HYSYS,
.model a crude oil with the following data
• The crude is the feed stock to oil
refining process
- Fluid Package: Peng Robinson

- standard Density = 29 API_60

Petroleum characterization




 petroleum characterization method in hysys conversion of laboratory assay analyses of condensate, crude oils, petroleum cuttings and coal-tar liquids into series of discrete hypothetical   components.  These petroleum components provide the basis for a property package to predict the remaining  thermodynamics and transport properties necessary for fluid modeling.



Aspen HYSYS produces a complete set  of physical and critical properties for a petroleum hypo component with minimal information.  However, the more information you can supply  about the fluid, the more accurate these properties will be, and the better 
the Aspen HYSYS  predict the fluid  actual behavior

what is HYSYS program?



Hysys is chemical process simulation used to mathematically model chemical processes, from  unit operation to full chemical plant  and  refineries  HYSYS is able to perform many of the core calculations of  chemical engineering, including those concerned with mass balance , energy balance,, heat transfer mass  transfer , and pressure drop . HYSYS is used extensively in industry and academia for steady-state and dynamic simulation, process design, performance modelling.
