May I ask everyone, what is the approximate annual operating time of the acidic gas flare in a sulfur plant?

How long is the annual emission time for acidic gas flares? I think it can be calculated based on startup and shutdown periods Sea friends, give an estimate
What era is this that we still have to line up torches? If queuing is really necessary, of course the shorter the time, the better
The start of work is mainly restricted by the timing of the temperature rise curve! Under normal circumstances, it takes 2-3 days to get started, and in cases where work stops early, it’s at most one day!
It can be calculated as 8,000 hours of operation per year
Of course, it is calculated based on 8,000 hours, with maintenance carried out every three years; the total time required for starting up, shutting down, and flaring is estimated to be 4 hours
Oh? Does your facility not flare the sour gas during operation? Are there any specific good methods? As far as I know, only Guangxi Petrochemical uses hydrogen co-combustion to start up operations without using flares. Do you have any useful experiences that you could share?
In accordance with GB31570 requirements, flares are not allowed to be used for emission, and you need to have two sets of sulfur treatment systems; it would be best if these two sets can operate without shutting down at the same time. Modern technologies such as ammonia-based desulfurization, sodium-based desulfurization, and complexed iron can all enable a single unit to operate without the need for a flare – of course, this is possible only if the facility is modified accordingly.
We currently have newly installed equipment, as well as two sets of sulfur treatment systems; one is in use while the other serves as a backup. It’s a sodium-based desulfurization process. What is the specific plan for starting up operations without using a flare?
Here, we usually start operations by releasing flares from the upstream purification unit
Could you describe it in detail? Upstream purification device?
