Regarding the destination of the gas released by the safety valve at the top of the distillation tower
Thread Content
For example, can the pressure-relieving gas from the safety valve of the initial distillation tower in a vacuum distillation unit be discharged directly? Is it possible to introduce it into a heater? There are regulations on this matter in the design specifications. Please ask those who are aware to help out.
The feed to the heating furnace must be supplied steadily, with fluctuations avoided as much as possible; especially since a large amount of material is released when the safety valve operates, and this material should not enter the heating furnace for combustion.
It cannot be released into the atmosphere; the high temperature makes it prone to catching fire
Thank you to the friend above! The problem now is not knowing where to discharge it It is not cost-effective to design a special torch for this purpose; what is the most economical approach? How do other similar small-scale refining units handle this issue? The safety valve of this tower we are going to install is very unlikely to activate; it hardly ever trips even once every few years. The small device can be turned on and off at any time; it’s fine if it emits something into the heating furnace, but it’s not clear whether this is allowed according to the regulations, as there’s no relevant guideline available.
It is absolutely unacceptable to release gases directly into the atmosphere. It is better to design an exhaust gas absorption tower to initially absorb the exhaust gases, and then send those gases that cannot be absorbed to an exhaust gas combustion furnace for burning before releasing them into the atmosphere at high altitudes! ! ! ! ! ! ! !
1. Direct evacuation is theoretically feasible, but it is not allowed due to environmental concerns. The distillate from the primary distillation tower mainly consists of light components and water, so it is reliable to send it to the flare. 2. Feed into the furnace. Not feasible. The function of a safety valve is to ensure safety; if it activates, it means there is a problem that threatens safety. At such times, nothing else should be considered – safety is the top priority. Moreover, the outlet of the safety valve is subject to backpressure limitations; what is the backpressure in the furnace? Is it stable, and can it ensure safety in the event of a large amount of gas suddenly entering the furnace?
