1. If all of the sulfur in the coal reacts to form H2S1 determine the air requirements for the Claus plant in kmol and standard m3 per kg of coal fed to the process.
2. Estimate the temperature to which the CO-H2 stream must be cooled to condense of the inlet CO, assuming ideal gas behavior and that CO is the only condensable component in the system. (The dependence of the vapor pressure of CO on temperature is given in Table 3-7 of Perris Chemical Engineer? liandhook.41 Determine how well the assumption of ideal gas behavior is satisfied by using the temperature calculated the first part of this question and the system pressure to estimate a compressibility factor for the product gas from the condenser using Kay's rule.
3. Determine the standard heats of Reactions. Discuss the purpose of feeding oxygen to the reactor.
4. Assuming no heat is lost to the surroundings, estimate the temperature of the gas and slag leaving the gasifier. (Hint: Choose the elements at 250C and 1 atm as reference states, and estimate Ht of coal from the higher heating value obtained using the Dulong formula)
5. At what rate (kW) is heat transferred to or from (state which) the methanol synthesis reactor to maintain its operation at 200°C You may assume that the recycle stream is at 40°C, and the fresh feed is at - 20°C.
The liquid stream from the scrubber goes to a dryer where the water is driven off leaving pure maleic anhydride - The moles of benzene that are completely oxidized in the reactor per mole of benzene fed into the reactor?
consider the binary cycle using the sodium and steamwater in the sketch below and operating at conditions in table 1.
In the direct steelmaking reactor based on the reduction of an oxidizing foaming slag by char (carbon) particles and droplets of iron containing 2% carbon. Estimate the total surface area of char and iron droplets needed to achieve the smelting ..
describe the principles of a vapour adsorption refrigeration system and compare this to a vapour recompression system.
Why a substance is being heated at a fast rate the temperature of decomposition
Enumerate and discuss the physical conditions that must be met in order for a caving mining method can be considered for ore extraction technique.
Determine the concentration of the exhaust gas and Determine the flow rate of exhaust gas through the smokestack.
the rate of flow to an ammonia synthesis reactor contains 25 mole ltbrgtnitrogen and the balance hydrogen. the flow
Monczka-Trent has two options: (1) its standard 2-day shipment or (2) a subcontractor who will team drive overnight with an effective delivery of 1 day. The extra driver costs $175. Handfields's holding cost is 35% annually for this kind of inventory..
Plot the fraction of ferrite, austenite, and cementite in equilibrium alloy containing (a) 0.6% C (b) 0.8% C and (c) 1.2% C as a function of temperature (25 C to 1400 C). What is the percentage of pearlite (eutectoid) in the above three cases at ro..
The reflux ratio is set at 4.0:1. Calculate the kg mol/h distillate D and bottoms W and their compositions. Also, calculate the number of theoretical plates required.
It is common that people are exposed to more than one hazardous substance at a time. The different substances may interact such that one substance may alter the toxicity of one or more of the chemicals present. Discuss the possible interactions th..
