Calculation of smoke-suppressing steam for torches
Thread Content
As stated in the title, the gas emission rate from the torch is 1000 t/h; the gases involved are ethylene, propylene, and water, with a molar ratio of 2:3:1. How can the amount of steam required for smoke suppression be determined?
Hey, we adjust the smoke suppression steam for our torches based on the burning conditions – if there’s black smoke, we increase the flow!
Currently, most torches are of this kind, with the steam volume being adjusted manually according to the burning conditions
According to the specifications in SH3009, section 9.1.12 explains how to determine the required amount of steam; this is the amount needed to achieve 100% smoke elimination. In practice, it’s not possible to eliminate all smoke, so generally 15% to 20% of that amount is used, as otherwise such an amount cannot be supplied. By being generous in the calculations and then deducting the water contained within it when it is in the air, the amount of steam required for smoke elimination can be determined, which serves as a basis for the design of the plant’s utility systems.
The SH3009-2013 standard includes a formula for calculating the amount of steam required to remove smoke; what’s important is to know the mass flow rate of unsaturated hydrocarbons
