Methane reacts with chlorine to produce methyl chloride and hydrogen chloride. CH4 + Cl2 → CH3Cl + HCl Once formed, methyl chloride can be chlorinated in subsequent reactions to form methylene chloride (CH2Cl2), chloroform (CHCl3) and carbon tetrachloride (CCl4). In a methyl chloride production process a reactor is fed with methane and chlorine in a molar ratio of 5: 1 (methane: chlorine). In the process the chlorine is consumed in its entirety. The selectivity observed in the process is 4 mol of CH3Cl / mol of CH2Cl2 and negligible amounts of chloroform and carbon tetrachloride. The product stream of reactor passes to a condenser where CH3Cl and CH2Cl2 are separated in liquid form, and CH4 it is separated from the HCl to be recirculated to the process (only CH4 is recirculated). The production of CH3Cl is 500 kmol / h. Calculate the flow and molar composition of the fresh feed, the HCl flow that occurs and the flow of methane recirculation.

1. Three tanks are interconnected non-interactively. The fluid enters the first tank at the flow rate q and the third leaves the tank at flow rate q3. The speed of the fluid coming out of the third tank is fixed by means of a pump. It is maintained. According to this, a) Mathematically the effect of the change in the velocity of the fluid entering the first tank on the liquid height in the third tank Please express. (The areas of the tanks are equal to each other.) b) If the velocity of the fluid entering the first tank is suddenly increased by 10 units, the height of the liquid in the third tank over time express the change mathematically. (The time constant of the first and second tanks are 2 minutes and 3 minutes respectively, area of tanks 1 m2 'D.) * Show the system schematically

Mixing of citric acid takes place in a 12-liter capacity tank. The tank has
initially (t = 0), 4 Liters of fresh water (no citric acid). Citric acid solution stream at 0.1 kg/L concentration enters the tank at a rate = 0.1 L/min. The citric acid solution leaves out from a
nozzle in the tank at a rate = (t+1) L/min. Assume the tank is well-mixed and no reaction takes place.
1. Sketch and label the tank and show if the system is steady state or not, why?
2. Derive the ODE that show the relationship between citric acid concentration and
time?
3. Solve the ODE to get a relationship between Citric acid concentration and time?

Hydrogen is produced by the reaction: ?? (?) + ?2? (?) → ??2 (?) + ?2 (?) The feed stream to the reactor is an equimolar mixture of carbon monoxide and steam, and it enters the reactor at 425 K and atmospheric pressure. If 70 % of steam is converted to hydrogen and if the product steam leaves the reactor at 750 K, how much heat must be transferred from the reactor?
