Design of Heat Transfer for a Chemical Reactor Assignment

Design of Heat Transfer for a Chemical nuclear nuclear reactor - Assignment ExampleThe instrumentation part includes putting in place the correct system such as closed loop control system, sensors and pneumatic valves for control of flow rate and temperatures.Much wait goes out to all the persons responsible in several ways for the success of this research, mostly to those who have do me gain much more than what the scholastic aspects of the course could have accorded. Much gratitude also goes to my lecturer for the fundamental knowledge he has provided in class.Production of Acrylic acid starts with propylene being partially oxidised in a fluidized -bed reactor. Propylene is broken down to acrolein in the process of getting catalytic gas at an oxidation stage. This takes place in presence of oxygen gas.The fluidized-bed reactor includes a packed-bed with a stirred tank that creates continuous flow reactors. It must posses some good characteristics of both heat and chaw transfe rs. Substrates moves upwards through the bed which is immobilized with enzyme at high velocity which moves the particles up leading to though mixing. The reactor is normally used in highly ex othermic reactions because it clears local hot-s push-down lists simply because of the mass and heat characteristics the fluidized -bed reactor has. The substrates are normally catalytic material where chemical reactants are given support. After achieving some optimal speed the reactor gets into a stage where the force of the fluid in the solids becomes enough to make a balance between the fluid and the solid materials. The contents of the bed-reactor begin to expand and swirl about in a manner equivalent to a agitated tank or a boiling pot of water after passing this level. This is where the reactor becomes a fluidized bed (Coulson, Richardson & Sinnott,1993).Pressure and temperature conditions in the process changes regarding the modality of reaction going on. Putting the fluidized-bed reac tor in the higher section with higher temperatures and pressure than other areas provides good results since it promotes the needed reaction. The vapor velocity influences the rate of circulation for the catalyst. The velocity for the catalyst in inversely
