Petroleum Assaya

A crude oil assay

   

is the chemical evaluation of crude crude oil feed  stocks by

 

petroleum testing laboratories. Each crude oil type has unique

  

molecular and chmical 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

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

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.
