Calculation of Waste-Gas Calorific Value
The typical vent-gas analysis from the recycle stream in an oxyhydrochlorination process for the production of dichloromethane (DCE) (British patent BP 1,524,449) is given below, percentages on volume basis.
Estimate the vent-gas calorific value.
100 gallons per minute flow of water at 50 degrees F passes through a theoretically 100% efficient heat exchanger. The hot side or energy to the heat exchanger is a 510 degree F hot gas (essentially steam).
Estimate the diffusion coefficient of Oil Dispersant A in a 10 mole percent Dispersant A -sea water mixture. The concentrated solution is non-ideal
If the feed quality is changed to 80 mol% vapour, the change in the slope of the q-line isA homogeneous reaction (R ® P) occurs in a batch reactor. The conversion of the reactant Ris 67% after 10 minutes and 80% after 20 minutes. The rate equation..
Design a storage and feed system for the sorbitol powder. Sorbitol has average bulk density 1.48 kg/liter, and can be assumed to have an average particle size of 200 μm.
U-235 undergoes many different fission reactions. For one such reaction, when U-235 is struck with a neutron, Ce-144 and Sr-90 are produced along with some neutrons and electrons.
Elaborate on the hierarchy of control measures used in Industrial Hygiene How would you calculate the noise problem at the factory and what control measures would you consider before you recommend the supply of hearing protection to personnel ex..
In the storage of flammable liquids, if the composition of the vapor-air mixture above the liquid surface falls within the flammability limits, a floating roof tank would need to used or the tank blanketed with inert gas. Check if the vapor compos..
Develop a mass balance for a continuous diafiltration step and indicate the volumetric flow rates and concentrations of different species in the different streams obtained.
A process to produce 1000 kgmol/h acetaldehyde, ethane is fed to the reactor at 1500 kgmol/h and the fractional conversion is 0.8. The product stream contains 2 mol% CO2. Calculate the molar composition of the product stream and the fractional select..
