When heavy oils are cracked in a catalytic or thermal cracking process, lighter hydrocarbon compounds are formed. Most cracking processes on heavy oil feeds form products with carbon numbers ranging from two to greater than twenty. How does the equilibrium distribution of hydrocarbon compounds with five carbons (C5 compounds) change as the temperature of the cracking process is increased at 200kPa?
Express the maximum radius (Rmax) and maximum thickness (Tmax) in terms of bulk oxygen concentration, Cb (mol/mL), diffusivity of oxygen through the device D (cm2/s) and maximum oxygen consumption rate, Vmax (mol/mL/s).
Select a process variable (pressure / temperature / level / flow) and conduct a literature survey to determine recent developments in process instrumentation field. Identify any one novel instrument and explain in detail the working of the instrument..
Empirical correlation/model for onset of flooding in gas-liquid flow in horizontal pipe MatLab
Calculate the work done in breaking up a drop of petrol of volume 1 cm3 into 109 drops. Surface tension of petrol is given as 26 dynes/cm.
A 1 m^3 isolated chamber with rigid walls is divided into two compartments of equal volume. The partition permits transfer of heat. One side contains a nonideal gas at 5 MPa and 300 K and the other side contains a perfect vacuum.
question 1a discuss in details on five types of health effects related to exposure to hazardous substances encountered
Write a differential mole balance on phosphoric acid and provide an initial condition. [Start by defining np (k mol) to be the total quantity of phosphoric acid in the tank at any time.]
A 30 mol% feed of benzene in toluene is to be distilled in a batch operation. A product having an average composition of 45 mol% benzene is to be produced. Calculate the amount of residue, assuming α = 2.5 and W0 = 100.
Figure shows the tensile engineering stress-strain behavior for a steel alloy. (a) What is the modulus of elasticity?
Component Mass in Final State, Please solve specific problem below rather than providing examples. A rigid vessel having a volume of 0.028m^3 initially contains a mixture at 21 degrees Celsius and 100 kPa consisting of 79% Nitrogen
Derive a Differential Equation which will show how temperature in the tank changes with time. State assumption used. Solve this model to obtain T(t) given that T(t=200s) = 50°C.
Adipic acid is used in the manufacture of nylon 6,6. It is made by hydrogenation of phenol to a mixture of cyclohexane and cyclohexane (known as KA oil-ketone and alcohol), followed by oxidation with nitric acid.
