Regarding the absorption stabilizer tower

We use ADV high-efficiency floating valve trays, which work well; they can handle C3 in the dry gas and C2 in the liquid hydrocarbons

Floating valve trays are used, as they are suitable for processes that require high separation precision such as gas absorption and distillation. In a distillation column, solid tray trays are used to reduce pressure drop, clogging, etc.

Here, we use new-type tray vertical trays for absorption, and floating valve trays for separation.

We use floating valve trays, which are no different from other types of trays.

The floating valve tray is covered with floating valves, which can be either circular or strip-shaped. Take the circular F1 type as an example: it resembles a circular bench with three legs, the three legs at the bottom being inserted into the triangularly arranged holes in the tray. As gas rises through these holes, the kinetic energy of the gas lifts the valve plates, allowing the gas to be blown into the liquid layer on the tray to create bubbling. The three legs on the valve disc serve to restrict the movement and opening degree of the valve disc. Additionally, there are three initial settling plates around the floating valve; even when the floating valve is completely closed, a certain distance is maintained between the valve plate and the tray, allowing for uniform bubbling even at low flow rates. Actually, the strip-shaped one is pretty much the same; it just has slit openings in a strip shape

Most of those in use today are high-efficiency trays, which, compared to the traditional F-1 type, offer higher mass transfer efficiency and greater operational flexibility. For the same processing load, the investment required for tower equipment is lower; when expanding or upgrading the facility, it is not necessary to replace the tower itself – only the trays need to be changed, thereby reducing equipment costs.

We use strip float valve combined trays; the use of combined trays allows them to function more effectively

A tray-type integrated absorption tower, characterized in that ventilated and overflow trays are evenly installed in multiple layers within the tower; an overflow weir and a liquid drop tray are provided on one side of each tray layer. The trays can be of the bubble type, sieve plate type, cyclone type, or floating valve type. This practical new design not only ensures that the carbon dioxide content in the gas meets the required process specifications, but also brings the hydrogen sulfide level in the gas to the standards required for precise desulfurization in ammonia synthesis, thereby eliminating the need for a separate desulfurization unit ； Reduce the resistance in the carbonization system, increase compressor pressure, and lower power consumption ； It reduces the load on the ammonia recovery tower, ensures that the ammonia loss in the raw materials entering the carbonization system meets the process specifications, eliminates the need for an ammonia cleaning tower that would lead to direct emissions, thereby reducing water pollution and protecting the environment.

We use composite inclined-hole trays
