I am currently working on the piping for equipment. In a 3000L reactor, acetyl chloride reacts under heating and reflux conditions over a period of 2 hours, releasing 1200 mol of HCl. Experts, what diameter of pipes would be appropriate to use? Urgent! Urgent! Urgent! ! !
Reply to 1# shenhanbing: 1200 mol of HCl equals 36.5 × 1200 = 43.8 kg. If this amount is released over two hours, the release rate is 36.9 kg/h. The density isn’t specified; assuming the standard density of 3.21 kg/m³ and a flow velocity of 8 m/s, the calculation yields a diameter of 22.5 mm (thus a DN25 pipe would be suitable, again under standard conditions). Under actual operating conditions, the density is less than 3.21, so the calculated diameter might be larger than DN25. Moreover, from an engineering perspective, the flow velocity of HCl gas should not be too high; it is recommended to use pipes with a diameter of at least DN50. -------The above LZ can be calculated using the operation density, and the flow velocity should be set to a lower value (3 m/h).
