1. Write down in dimensionless form the material balance equation for a laminar flow tubular reactor accomplishing a first-order reaction and having both axial and radial diffusion. State the necessary conditions for solution.
2. Falch and Gaden studied the flow characteristics of a continuous, multistage fermentor by injecting an impulse of dye to the reactor [E. A. Falch and E. L. Gaden, Jr., Biotech. Bioengr., 12 (1970) 465]. Given the following RTD data from the four-stage fermentor, calculate the Pea that best describes the data.
Describe and interpret D&B financial reports using definitions from the D&B website.
You are requested to flash the mixture so that the liquid stream is 85% of the inlet (by mol). If the pressure is 1.5 bar, what temperature should be used?
For high conversion in a highly exothermic solid catalysed reaction, use a __________ bed reactor. 1. fluidised bed reactor followed by a fixed
Determine the number of theoretical plates required to reduce to hydrocarbon content of 0.05 mole % assuming the oil is non-volatile.
A Carnot cycle operates in a closed system using steam: saturated liquid at 20 bar (state A) is heated isothermally until it becomes saturated vapor (state B), expanded by reversible adiabatic process to 10 bar (state C), partially condensed to st..
In the process of Example 6.2, the flow rte of streams 1′ and 2′ is made very high, while the state of streams 1, 2, and 1′ are the same as in the previous example. Repeat the calculation of entropy generation for these new conditions.
