Regarding whether ethylene oxide can be fed into the flare
Thread Content
Can ethylene oxide medium be sent to the flare? In terms of its properties, ethylene oxide decomposes easily at 400 degrees. It was mentioned that it decomposes very readily in torches, which leads to explosions; I’m not quite sure about this. When ethylene oxide decomposes, it produces substances such as methane, ethylene, and formaldehyde. The explosion limit for ethylene oxide is between 3% and 100%. Additionally, it was found in other sources that ethylene oxide has a decomposition explosion temperature of 561 degrees; could this be related to it? Please explain
SH3009 _ Design Code for Fuel Gas Systems and Flammable Gas Emission Systems in Petrochemical Enterprises, 4.02.2 Flammable gas mixtures with concentrations within the explosive limit should not be discharged into the plant’s overall flammable gas emission system.
It’s possible to use torches, but the cost is too high. However, given the current strict environmental regulations, there is still hope
1. Ethylene oxide has a low boiling point of 10.7°C, and it tends to condense, liquefy, and accumulate once it is released into the flare system. 2. If iron ions are present in the pipeline, they can catalyze the self-polymerization of ethylene oxide, generating a large amount of heat that may lead to an explosion.
The explosion range of ethylene oxide is too wide; it cannot be sent to a flare
Agreed; devices that have been used as EO/EG units have not been sent to the flare.
