Week 4 Process 1: Consider the process below: Water in Combustor Steam Generator Gas In Gas Out Combustor exit Steam Out A methane (CH) and air mixture is burnt in the combustor then the heat is recovered to produce steam. The CHa/air mixture comes in at 25°C and contains 10 kg/h of CH4 and 500 kg/h of air (assume 79% Nitrogen (N2) and 21 % Oxygen (O2)). The final outlet gas leaves at 100 °C. The combustion reaction follows the...

Reaction is A-->B
is carried out adiabatically in a CSTR. The reaction is second order in A. The feed, which is equal molar in water (which contains the catalyst) and A, enters the reactor at a temperature of 52 C and a total volumetric flow rate of 10 dm3/min. The concentration of A entering the reactor is 4 molar. a) What is the reactor volume to achieve 80% conversion b) What conversion can be achieved in a 1000 dm3 CSTR?...

Ethylene oxide is produced by the catalytic oxidation of ethylene: C2H4 (g) + 1/2 O2 (g) --> C2H4O (g) An undesired competing reaction is the combustion of ethylene to CO2. The feed to a reactor contains 2 mol C2H4/mol O2. The conversion and yield in the reactor are respectively 25% and 0.70 mol C2H4O produced/mol C2H4 consumed. A multiple-unit process separates the reactor outlet stream components: C2H4 and O2 are recycled to the reactor, C2H4O is sold, and CO2 and...

Terephthalic acid (TPA) is synthesized from -xylene (PX) in the
process C8H10 +302 – C8H6O4 +2H2O shown below. A fresh feed of pure
liquid PX combines with a recycle stream containing PX and a
solution (S) of a catalyst (a cobalt salt) in a solvent (methanol).
The combined stream, which contains S and PX in a 3:1 mass ratio,
is fed to a reactor in which 90% of the PX is converted to TPA. A
stream of air at 25...

Required information A shell-and-tube heat exchanger is used for cooling 47 kg/s of a process stream flowing through the tubes from 160°C to 136°C. This heat exchanger has a total of 100 identical tubes. each with an inside diameter of 2.5 cm and negligible wall thickness. The average properties of the process stream are: p = 950 kg/m”, k = 0.50 W/mK, Cp=3.5 kJ/kg.K, and -20 mPas The coolant stream is water (cp=4.18 kJ/kg K) at a flow rate of...

Acetic anhydride is a clear liquid with a pungent, penetrating, vinegar-like odor. The largest application of acetic anhydride is as a raw material in manufacturing cellulose acetate fibers and plastics. It is also used in the production of aspirin, acetaminophen and other pharmaceuticals manufacturing. In an intermediate step in the production of acetic anhydride, carbon monoxide and carbon dioxide are reacted with hydrogen to make methanol according to the following balanced chemical equations:...

8) Ethylene oxide is produced by the catalytic oxidation of ethylene. C2Ha(g)+1/202(g) C2H4O(g) An undesired competing reaction is the combustion of ethylene to CO2. The feed to a reactor contains 2 mol C2H4/mol O2. The conversion in the reactor is 25% , and 0.70 mol of CaHeO is produced per mol of C2H4 consumed. A multiple- unit process is used to separate the products: C2H4 and O2 are recycled back to the reactor, C2H4O(g) is produced as a product (at...

Methane (CH4) and oxygen (O2) react to form formaldehyde (CH2O) (reaction #1), with a competing side reaction (#2) in which methane and oxygen form carbon dioxide (CO2): CH4(v) + O2(g) -> CH2O(v) + H2O(l) (reaction #1) CH4(v) + 2O2(g) -> CO2(g) + 2H2O(l) (reaction #2) A fresh feed of an equimolar gas mixture of CH4 and O2 is combined with a recycle stream and fed to a reactor. The single-pass conversion of CH4 is 30% and the selectivity of CH2O...
