310 cubic meters of vinyl chloride monomer are produced per hour. The temperature of the hydrogen chloride pipeline is 265 K and the pressure is 130 KPa. What is the flow rate of hydrogen chloride in cubic meters per hour? Please write down the formula
310 cubic meters of vinyl chloride monomer are produced per hour. The temperature of the hydrogen chloride pipeline is 265 K, and the pressure is 130 KPa. The density of vinyl chloride is 0.91 tons/m³, with a molecular weight of 62.5; the density of hydrogen chloride is 1.629 g/L (under standard conditions of 273.15 K and 101 kPa), with a molecular weight of 36.5. The volume of hydrogen chloride required to produce 310 m³ of monomer is calculated as follows: 310*0.91/62.5*36.5/1.629*10^6 = 101.1*10^6 L = 101,100 m³. According to the ideal gas law, PV = nRT, where nR is a constant. Using the formula P1*V1/T1 = P2*V2/T2, we have 130*V1/265 = 101*101,100/273.15; thus, V1 = 76,203 m³. The values above are theoretical only; in actual production, factors such as mixing ratios and conversion rates must also be taken into account.
The formula upstairs is correct; there’s a slight discrepancy in the figures: 76228.5 m3
