A chemical manufacturer produces ethylene oxide by burning ethylene gas with air in the presence of catalyst. If the conditions are carefully controlled, a substantial fraction of ethylene remains unconverted and some is completely oxidized to form carbon dioxide and water. Formation of carbon monoxide is negligible. After the gases leaving the absorber is as follows: 9.6%CO2, 3.0%O2 and 6.4% ethylene. Of the ethylene entering the reactor, what percentage is converted to ethylene oxide?
A circular lake of diameter 2.5m is receiving wastewater with a flow rate of 25 L/sec from a village has phosphorus concentration of 0.5 mg/L. The lake receives Phosphorus point source concentration of 0.8 g/sec. If the wastewater is completely mixed in the pond and removes phosphorus with a removal rate of 12 m/year, find the concentration of phosphorus (mg/L) in effluent water stream? Assume steady state. (Round-off to one decimal place).
The production of cement results in significant GHG emissions. The emissions are caused by the decomposition of calcium carbonate (limestone) to calcium oxide (lime) and carbon dioxide. This process known as calcination, is carried out in kilns. Therefore, additional GHGs are emitted as a result of heating the kilns. A large cement manufacturer uses a mix of coal, natural gas, and biomass in its boiler. This mix produces the following amounts of GHGs per Million BTUs of energy: • 250 lbs CO2/MMBtu • 5 lbs CH4/MMBtu • 0.36 lbs N2O/MMBtu Process carbon emissions from the calcination process produce 925 lbs of carbon dioxide per metric ton of cement. In addition, the plant uses 1.7 Million BTUs of energy per metric ton of cement. If the plant produces 180,000 metric tons of cement annually, how many metric tons of CO2e does it emit?
Certain mole of charcoal (12C) has to be completely converted to CO2 after reaction with the oxygen of air. If double amount of air (mole basis) was supplied in the reactor then find the average molecular weight of the outlet gas mixture stream. Note that, carbon has no reaction with nitrogen in this case.
A drug is infused continuously intravenously (IV) for treatment of a particular disease. The volume of the body fluid V = 16 liters. The drug is excreted (removed) through the kidneys at rate ke , proportional to the concentration of the drug in the body fluids. The drug is ineffective and not used by the body if its concentration is below Cmin and becomes poisonous if the concentration goes over Cmax . It is metabolized at a rate km as the concentration is >=Cmin. Let the parameter values Cmin= 4 mg/l, Cmax =40 mg/l, ke = 0.2/hr and km = 0.3/hr.a. How much is the maximum possible rate of infusion of the drug?b. How long the drug would continue to be effective if the infusion has been stopped as the concentration reached at the maximum level?
Methanol (CH3OH) is produced in the reaction of carbon dioxide and hydrogen via the reaction and process given below: CO2+3H2→CH3OH+H2O The fresh feed to the process contains hydrogen, carbon dioxide, and 0.400 mol% inerts (I). The reactor effluent passes through a condenser that removes essentially all of the methanol and water formed and none of the reactants or inerts. The unreacted reactants and inerts are recycled to the reactor. To avoid buildup of the inerts in the system, a purge stream is withdrawn from the recycle. 100 mol/h of feed to the reactor (not the fresh feed to the process) contains 29.5 mol% CO2, 68.0 mol% H2, and 2.50 mol% inerts. The single-pass conversion of hydrogen is 46.71%. What is the recycle-to-fresh feed ratio?
Methane is burned with air in a continuous combustion reactor that is at steady state.The feed to the reactor contains 7.80 mole % CH4, 19.4 mole % O2, and 72.8 mole % N4.

Carry out a degree of freedom analysis of the process, and calculate the molar composition of the product stream.

What is the Molecular weight of a certain volatile liquid which is placed in 225 g flask which has total capacity volume of 252.17 mL. After the liquid was heated to 96.7 oC the gass volatilized and the weight of the flask measure 227.33g. What is the could be the MW of the volatile sample?
Although the reaction could heat up the gas up to thousands of degrees in Celsius, the product gas mixture could be cooled down dramatically when it transfers some of the heat to the piston. During that 2 – 3 milliseconds of reaction and the stroke, the heat that cylinder wall absorbs could be ignored as the reaction happens too fast to have the heat exchange while expansion, it is the heat absorbed by the top portion of piston we should consider because it contacts the gas mixture all the time during the process, and it is made of aluminum alloy, in which aluminum is one of the excellent heat-conducting metal. (When running normally, the temperature of the cylinder should be around 210 oF ) A) As mentioned, the diameter of the cylinder is 8.35 cm, and the thickness (height) of heated portion of the piston is estimated 1 mm. Consider the shape of heated portion of the piston is a right cylinder, calculate the volume of this heated portion. Given the density of Aluminum is 2.71 g/cm3,…
