Comparison of gas desulfurization facilities

Integrated tower equipment is compact, and generally not considered dangerous due to gas desulfurization； High towers are used for the regeneration of waste gas, with emissions at high altitudes; this results in high energy consumption, uneven gas-liquid contact, and low regeneration efficiency ； The gas-liquid mixture in the jet regeneration is not optimal, and the nozzles tend to clog, leading to liquid overflow.

There is also the low-tower regeneration process, but it is not used very often. High-tower regeneration is commonly used.

In coking, high-tower regeneration is used more often, while single-tower desulfurization is also employed; however, single-tower desulfurization presents many practical problems in production, so it’s advisable to communicate with manufacturers that have used it. Slot-type regeneration is also available, and it works well too. It is recommended to choose an experienced construction company

The advantage of a single-tower design is that it saves space, but it has a fatal flaw: due to structural issues, the residence time of the desulfurization solution inside the regeneration tower is insufficient, which severely affects the effectiveness of regeneration； It is inconvenient to conduct inspections ； Cleaning issue of clogged regenerative ejector (too high to service conveniently). The circulation pump is required to have a high head, in order to overcome both the height of the tower and the pressure head required by the ejector, which is approximately 0.3 MPa. I do not recommend using this process. The regeneration of high towers relies on air compressor air distribution, ensuring stable operation. It has high energy consumption. Low-tower regeneration relies on an ejector to draw in air, eliminating the need for an air compressor; however, it requires higher standards in terms of design, installation, and operation. The ejector can develop scaling over time, which affects air intake, so it needs to be cleaned regularly.

It was clearly stated on the fifth floor: for coking purposes, high towers are currently the best option. Slotted types are also useful, but they place high demands on the design and construction teams. Tower-type desulfurization is not recommended; although it requires less space and one fewer pump, it remains uncertain by how much the energy consumption associated with the injector head pressure is lower compared to high-tower systems

Our company uses MTS desulfurization catalysts for high-tower regeneration； A new desulfurization system has been installed, using spray regeneration.

Personally, I think high-tower regeneration is the better option for coking desulfurization, but attention must be paid to the details in the design and construction process; otherwise, there will be many problems during operation later on!

Low-tower regeneration relies on an ejector to draw in air, eliminating the need for an air compressor; however, it requires higher standards in terms of design, installation, and operation. The ejector can develop scaling over time, which affects air intake, so it needs to be cleaned regularly. :lol:lol:lol Take a look at FRC
