CO2 is a major concern.
IQS organises a postgraduate course on Compamy Enviroment Engineering. Follow this link for official website for this module on iqs web.

Objectives: Back to INDEX


1. - Design a machine to transfor CO2 into other components withou generating additional pollution.
A first approach is carried out defining the entrance of CO2 + 2H2O at 25C (298 K).
Chemical reaction is produced due to radiation heating of 199 glass fiber heaters to produce CH3OH + 3/2 O2.
The heating energy is calculated to produce the chemical reaction and increase the temperature of the mixture to a level considred of safety.

Cut plots of CFD simulation showing velocities of fluid during chemical reaction.

Velocity is calculated according to theory at entrance and exit taking into consideration that exit is at higher temperature and therefore with lower density and higher velocity.
Simulation showed that some areas have a close to zero velocity where heating is not efficient to the mixture.

Cut plots of CFD simulation showing temperatures of fluid during chemical reaction.

Temperature is calculated according to theory at entrance and exit.
Simulation showed that some areas have a huge temperature not expected according to theory due to the low velocities of the mixture.

CONCLUSIONS:
A new design is proposed to circulate the mixture aroound all radiators with uniform velocity distribution.

2. - Optimisation of machine.
Once the machine is designed the manufacturing of parts are studied from an enviromental point of view.

3. - Final design.
Once the machine is optimised the production starts using normalised parts such as racor.

Cut plots of CFD simulation showing velocities of fluid during chemical reaction.

Velocity is calculated according to theory at entrance and exit.
Simulation showed that areas with close to zero velocity are reduced to near wall regions.

Cut plots of CFD simulation showing temperatures of fluid during chemical reaction.

Temperature is calculated according to theory at entrance and exit.
Simulation showed that temperature is increased just 20K from theoretical values with improved design.

CONCLUSIONS:
A new design is proposed to circulate the mixture aroound all radiators with uniform velocity distribution.
