Devise a control system for the distillation column described in Chapter 17, Example 17.2. The flow to the column comes from a storage tank. The product, acetone, is sent to storage and the waste to an effluent pond. It is essential that the specifications on product and waste quality are met.
question 1a outline the provisions of occupational safety and health act 2005 with regard to substances hazardous to
The feed (CAo= 1.0, CRo= 0, CSo= 0) enters two mixed reactors in series (?1= 2.5 min,?2= 10 min) knowing the composition in the first reactor (CA1= 0.4, CR1= 0.4, CS1= 0.2),find the composition leaving the second reactor (using fractional yield co..
Determine the values of the constants a and c and state the units and draw the path on a PV diagram also draw Path on the diagram and calculate the heat and work interchanges between the system and surroundings.
Formulate arguments for and against the idea that risk assesment can and should be separated from risk management. Discuss land as a natural resource and how and why it is or should be regulated by environmental laws.
A feed of 50 mole % hexane and 50 mole % octane is fed into a pipe still through a pressure reducing valve and then into a flash disengaging chamber. The vapor and liquid leaving the chamber are assumed to be in equilibrium. If the fraction of the..
Estimate the diffusion coefficient of Oil Dispersant A in a 10 mole percent Dispersant A -sea water mixture. The concentrated solution is non-ideal
the rate of flow to an ammonia synthesis reactor contains 25 mole ltbrgtnitrogen and the balance hydrogen. the flow
Calculate equilibrium products at 500K for the reaction of 1 mole CO and 1 mole H2O according to the water-gas shift reaction (CO • H2O CO2 • H2) as a function of temperature four ways
Styrene can be made by catalytic dehydrogenation of ethyl benzene. The reaction is usually carried out in the presence of steam, which acts as a heat carrier and reduces coking on the catalyst.
Discuss how the phase equilibria of mixtures are represented using diagrams similar to the pressure-temperature and pressure-specific volume diagrams for one- component systems. Use the example of a mixture of ethane and heptane to illustrate your..
Lead chloride dissolves in water according to PbCl2(s) Pb2++2Cl-(aq)
Calculate the heat when 100.0 mL of 0.500 M HCl is mixed with 300.0 mL of 0.100 M Ba(OH)2. Assuming that the temperature of both solutions was initially 25.0C and that the final mixture has a mass of 400.0 g and a specific heat capacity of 4.18 J..
