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.

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

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

Oil 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

  See the simulation 

 

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
