a) List the dissimilar Heat transfer equipment involved in your plant. Also describe the governing principle or modes of heat transfer for every equipment that listed. Determine the Heat transfer area for any heat exchanger which is listed in your plant equipment with help of process data sheet or from real plant data.
b) In a catalytic cracking regenerator catalyst particle at 600 oC are injected in to air at 700 oC in a fluidized bed. Neglecting the chemical reaction, how long will it take for a 50 micron meter to be heated to within 5 oC of the air temperature? Suppose the heat transfer coefficient is the similar as for a spherical particle falling at its terminal velocity.
