Hysys (Pressure drop calculation in a pipe)




Water is flowing in a 10-m horizontal smooth pipe at 4 m/s and 25°C. The pipe is Schedule 40, 1 in nominal diameter. Water inlet pressure is 2atm. Calculate pressure drop.

Water properties:
Density 1000 kg/m3
Viscosity =0.001 kg/m s.

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 .

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)






 

Crude Oil Assay >







With the aid of the oil characterization option in Hysys, model a crude oil stream with.

 

following data:

 

The crude oil is the feedstock to a refining process
Fluid package: Peng Robinson 
Standard Density = 29 API_60

? 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
> use resays default

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   










 

Fluid Package in Hysys


Physical Properties: Fluid Package

.Property Package Selection -      

.Plenty of packages -      

. Each has its specification-       

.Typically, you will know which Package to Apply-
