Interaction between set points and process variables


It is an extension of steady-state whereby time-dependence

 

is built into the models i.e. accumulation of mass and energy.

 

Control of real processes are possible.

 

The calculations are more complex and time consuming.

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 flow rate of the

 

 cold stream passing throughout the exchanger.

HYSYS SIMULATION/CSTR

INTRODUCTIC 

 

In this lecture, a flowsheet for the production of propylene glycol is presented.

 

Propylene oxide is combined with water to produce glycol in a CSTR

 

• The propylene oxide and

 

water feed streams are combined in a mixer. The combined stream is fed to a reactor, operating at atmospheric pressure, in which propylene glycol is produced.

PROBLEM STATEMENT

 Simulate the production of Propylene Glycol from Propylene oxide and excess water

 

using a CSTR.

Simulate Equilibrium Reactor

PROBLEM STATEMENT

 The new application of hydrogen as a raw  for fuel cells for mobile power source (PEM fuel cells) requires that the inlet gas have a concentration lower than 10-20 ppm.

 Otherwise, the anode is poisoned and the cell efficiency abruptly drops. Hence, if the hydrogen is produced from hydrocarbon or alcohol reforming, purification is required in 

 order to reduce the CO levels to cell requirements. The most technologically feasible purification train consist of a water gas shift reaction (WGS). 

The reaction 

CO + H20 <----------------->CO2 + H2 

has been employed for 40 years in the industrial process for H2 production from liquid and gaseous hydrocarbon. The role of the WGS reaction is to increase the H2 yield and decrease the CO concentration, which is a poison for some catalyst used.

LEARNING OUTCOMES

>Simulate equilibrium reactor and reactions in HYSYS. 

>Re-Add the reactions and reaction 

>Attach reaction sets to the fluid package.
