The line of the high-voltage desulfurization device in the gas holder is blocked
Thread Content
The gas holder recovers all sorts of messy waste gases, and the pipelines are not functioning properly; the pressure difference between the compressor outlet and the desulfurization system is almost 2 kilograms. Do I need to turn on the heat tracing when the weather gets a bit colder? All exhaust gases from this system are directed into the gas collection cabinet, and a permanent flame is maintained in the flare to ensure there is always a flame present. Are there any units that have encountered this problem?
Blockages have occurred; connect steam to the desulfurization unit to blow it out, or keep the heat tracing on all the time. The composition of gas tanks is too complex.
Uh, I guess the line scanning is done by now
The pipeline from the gas compressor outlet of the gas holder to the desulfurization unit is generally around DN200 in diameter. Such pipelines are usually quite long, so it is important to check the downspouts in the ductwork where there may be uneven surfaces. Generally, there is also a cooler in front of the gas buffer tank in gas cabinets, which can also cause an increase in pressure drop.
At the initial design stage, a DN100 pipe was used; now that there is an additional compressor, I feel that the available power isn’t sufficient. The nucleation should have led to complete crystallization; it happened once before. In winter, it might be advisable to reduce the operation of the cooler or even remove it altogether to prevent crystallization due to low temperatures; alternatively, keep the heating system active at all times
Forgot that the cooler can’t be moved; otherwise, the gas with liquid contents would be sent to desulfurization. . .
The recovered components are certainly quite complex. Desulfurization of the recovered gas may lead to the crystallization and blockage of salts and impurities due to the long length of the delivery pipelines. In addition to maintaining continuous heating, it is recommended to drain liquid from the lowest points on a regular basis
In particular, the gas from the sulfur-acidic water vapor stripping and degassing tank has a high salt content; if it enters the gas holder, it can easily cause salt buildup in the compressor of the gas holder, resulting in a reduction in gas output.
Low-vane numbers should not result in the emission of substances of types C3, C4, and C5; C1 and C2 are no problem.
Today I went to check the gas line connected to the gas holder, and found that our gas line is quite long and lacks heating or insulation. The new units with three compressors have not been turned on yet; our company is located in the Northeast. May I ask how things are upstairs?
