Gas drainage treatment
Thread Content
The fuel I use in my heating furnace is dry gas. There is a liquid separation tank before the dry gas enters the furnace, and it is necessary to drain the liquid from this tank on a daily basis. Each time this drainage is carried out, it poses a problem for the workers. Does anyone have any good solutions?
Start from the source, identify the reasons for gas carrying liquid, and cut off the transmission channels: lol
The dry gas comes through the plant’s pipeline network; it contains a high amount of liquid
Several of the company’s units discharge wastewater manually into the sewage treatment facility
In my opinion, the buffer tank at the outlet of the dry gas compressor is not capable of effectively separating liquids, which results in liquid contamination. I think it would be possible to address this by reducing the compression ratio or by using a liquid separation tank with cooling, but these solutions may not be practical or cost-effective.
Failing to address the problem at its root will only result in doubled effort with half the outcome, being completely futile; it’s better to increase the size of the gas tank and install a control valve for liquid removal.
It can be pressurized to the flare tank; we added a 25-inch pipeline, installed a double-flange level gauge, and added a small control valve, and the result was good.
It can be solved from two aspects: first, increase the dry gas temperature by adding heat tracing to the pipeline. II. Draw a line from the bottom of the liquid separation tank to directly pump away the liquid phase and send it to the tank area for further processing.
It can be pressurized to initiate catalysis; this condensed oil can be reused
Condensate oil is usually sent to the crude gasoline tank and not discharged directly. The source of the problem needs to be identified – it’s necessary to find out where the liquid is coming from. Generally, the amount of liquid involved isn’t very large. This is a standard procedure in such installations; workers refer to it as “pressing oil.” I’ve done this many times, and there’s no need to add extra pumps – just make sure to be careful not to let the liquid flow in the wrong direction.
1. Source control. 2. Add heat tracing. 3. Add oil pressure line recovery. From a safety perspective, try to avoid on-site discharge or cutting out for treatment.
