Figure shows a simple heat-exchange system. A feed stream is heated by heat exchange in a plate exchanger and then further heated in a steam heater before entering a fixed-bed reactor. The product from the reactor is cooled in the plate exchanger and then further cooled using cooling water. Exchanger specifications and current performance are given in the figure. Propose modifications to the system to allow a revamp to 50% higher capacity.
question 1with regard to the asymmetric heck reaction - from the rccent literature 2010-2014 please give three examples
How will the mole fractions of benzene and toluene in the liquid change with time (increase, decrease, or remain constant)? Explain your answer.
Combustion of Ethane: Stack Gas Molar Composition, Ethane is burned with 50% excess air. The percentage conversion of ethane is 90%. Of the ethane burned, 25% reacts to form CO and the balance reacts to form carbon dioxide
Make a rough estimate of the cost of steam per ton, produced from a packaged boiler. 10,000 kg per hour of steam are required at 15 bar. Natural gas will be used as the fuel, calorific value 39 MJ/m3 (roughly 1 MMBtu/1000 scf). Take the boiler eff..
One of the classical methods for the determination of the manganese content in steel is to convert all the manganese to the deeply colored permanganate ion and then to measure the absorption of light.
Assume the plant is built at time zero and begins operation at full rate in year 1. Assume the rate of corporate income tax is 35% and taxes must be paid based on the previous year's income.
If the face opening for a laboratory hood installation is to be 2 feet high and 5 feet wide, what volumetric flow rate is required to generate a face velocity of 100 ft/min?
a. Estimate the feed flow rates of glycine and guaiacol that would be needed to produce 100 kg/day of the API. b. Estimate how much product is lost in the thin-film evaporator.
using the concept of a mass balance describe how environmental engineers and scientists model the carbon cycle in the
You are required to write a mini project that is structured in such a way as to answers all the questions contained within the project description.
Design a condenser for the following duty: 45,000 kg/h of mixed light hydrocarbon vapors to be condensed. The condenser is to operate at 10 bar. The vapor will enter the condenser saturated at 60 °C and the condensation will be complete at 45 °C.
a. Develop a general equation that relates the average value of n to the mass of a given mixture of PCBs and the mass of AgCl produced. b. A 0.1947-g sample of a commercial PCB yielded 0.4791 g of AgCl. What is the average value of n for this samp..
