Questions about the torch
Thread Content
I asked that there are two sets for catalysis, two sets for coking, and two sets for hydrogen addition; all processes such as subsequent catalysis, hydrogenation, gas separation, reforming, etc., use one flare system. Generally, torches are not used; they are basically recycled. But sometimes the devices leak or have flare vents, making it difficult to locate them; it is necessary to check each device one by one. Dear sailors, are there any other ways?
Reply to 2# linweihua6: It’s rather troublesome and not feasible. No problems with that device can be detected through analysis.
Sinopec requires flow meters to be installed at the outlets of each unit for flare gas discharge, but there is currently no good solution for this
It’s best to look for each device; if they really want to find it, it’s still possible, but otherwise I think it will be quite difficult
At the moment, we have no choice but to turn off the low-pressure gas valves one by one, which is quite troublesome. Do any of you have any good suggestions? ?
:Dizzy: Our devices have the same problem; we have to check each device one by one and manually inspect the safety valves
If the emission levels are low, sampling the gas after it has merged in the main pipeline for analysis of its composition can still be quite useful, as the gases emitted by different devices vary. Also, if it is not admitted, severe action will be taken if caught.
I think installing an online analyzer is a viable option. Serious action will be taken!
Large, standard refineries should have one low-pressure gas line for each unit; at the flare site, these lines are connected together, and when high-pressure venting occurs, the low-pressure gas cannot be vented.
We also have this problem here. Actually, placing a torch isn’t a big deal; the issue is that it’s placed there but not acknowledged. This, in turn, caused the leader’s anger. There’s no good solution; with a flow meter, even small leaks cannot be detected. Closing the main valve of the discharge device poses an even greater safety hazard. Someone here suggested adding a water seal, but it wasn’t implemented. Let me tell you something: once, during scheduling, the torch was very large. I asked each device, but none of them admitted it, so I went and checked them one by one on site. I noticed that a layer of frost had formed on the outlet pipeline of the safety valve, and it hadn’t melted yet. We were on the scene and asked the operators inside the unit, but they still refused to admit it. It’s so ridiculous~~~
