Hydrogen sulfide stripping tower
Thread Content
There are a flare line and a liquid vent line connected to the outlet of the reflux pump at the top of the hydrogenation desulfurization tower for diesel in Plant 5. What is the purpose of these lines? Urgently needed
This portion of light hydrocarbons is transported when the liquid level is high. In some cases, when coking is not in operation, the gas from the vent tank is sent to the flare, while the liquid is directed to the sludge oil tank area.
The pump outlet contains liquid and the temperature is not high; could you explain this in more detail?
Are you continuing to pump reflux when the level in the reflux tank is high? Excessively high liquid levels can cause acidic gas to carry liquid with it~~~~~ When the liquid level is too high, some of it should be drained to maintain a normal level~~~
What is the purpose of the flare line at the outlet of the reflux pump in the hydrogen sulfide stripping tower?
Just vent it; what else can you do at the flare tower? It depends on your specific process. Here, we first go to the flare tank.
Why is there no reflux pump at the top of the split tower?
The product of the fractionation tower is naphtha; when its liquid level is high, it is sent directly to the tank area
You’re truly talented – amazing! May I ask which organization you work for? Surely your company provides a lot of training, right?
You are referring to the top tank of the H2S stripping tower, right? Light gases in this section are generally C1 and C2 hydrogen gases sent to the coker for recovery; the non-condensable liquid from the reflux pump is also sent to the coker for recovery. Under normal conditions, reflux is used, and only when the tank contains a large amount of liquid is it sent there instead
