What to do if the pipe diameter is too large
Thread Content
We designed a pilot plant with a capacity of 100 t/a. Since it is a gas-phase reaction and the proportion of carrier gas is high, the gas flow rate entering the reactor in this pilot plant is very large; the diameter of the piping used is 250 mm, and the gas velocity is 10 m/s. If production scale is expanded in this manner, the diameter will become even larger, possibly reaching 3 to 5 meters. So I’d like to ask if anyone has encountered a similar situation, and what methods can be used to reduce the pipe diameter.
So, is it only possible to reduce the diameter by increasing the pressure, using compressed air? !
Increase the larger end. It’s simple – just increase the larger size. It’s simple – just increase the larger size. It’s simple
Parallel pipes can be considered; by dividing the required materials into several parallel pipes fed into the reactor, the diameter of the pipes can be effectively reduced. However, this will increase costs; therefore, provided the operating conditions permit it, it is better to increase the gas pressure and its flow rate.
