What are the factors that affect the absorption efficiency of the absorber in delayed coking?
1. The effect of operating pressure on absorption efficiency 2. The effect of operating temperature on absorption efficiency. Absorption is a process in which the components of a gas mixture are separated based on their different solubilities in the absorbent; this is a form of physical absorption. The efficiency of the absorption process depends on many factors, such as the oil-to-gas ratio, operating temperature and pressure, the properties of the absorbent and the gas to be absorbed, the gas-liquid flow patterns within the tower, the number of trays, and the structure of the trays (or the height and structure of the packing). For a specific unit, the absorbent, the gas to be absorbed, and the conditions of the equipment are all already determined; in such cases, the absorption efficiency relies mainly on adjusting the oil-gas ratio as well as the operating temperature and pressure. Generally, the oil-to-gas ratio (by mass) in the absorption tower should be controlled at around 2
The influence of operating pressure, temperature, and flow rate on the absorption efficiency.
It is recommended that the poster study the operation procedures carefully
The pressure in the absorption tower, the amount of absorbent and supplementary absorbent used, the ratio between absorbent and supplementary absorbent, the operating temperature, as well as the degree of desorption in the desorption tower – all these factors have an impact. I hope this helps you
In addition to conventional factors, it is also necessary to consider whether, in the case of a packed tower, there is blockage or flow deviation； For floating valve trays, it is necessary to consider whether the number of openings is sufficient to prevent excessive liquid leakage.
In addition to conventional factors, it is also necessary to consider whether, in the case of a packed tower, there is blockage or flow deviation； For floating valve trays, it is necessary to consider whether the number of openings is sufficient to prevent excessive liquid leakage.
This should be specified in the operating procedures, right... Hehe, is there anyone else around?
Process influences: operating pressure, temperature, absorption dose, whether desorption is excessive, and the quality of the absorbent and supplementary absorbent. Equipment impacts: tower, gas-liquid load on the trays, heat removal rate from the intermediate cooler, and the location where the absorbent enters the tower.
