Problem with pressure drop?
Thread Content
1. What is pressure drop? 2. In the sulfur recovery process, what is the relationship between pressure drop and the volume of acid gas being processed? According to relevant books, the pressure drop is directly proportional to the square of the volume of gas being processed? I’m not sure if this is correct, but what kind of gas does the amount of gas to be processed refer to (the amount of acidic gas? Or is it the sum of the acid gas volume and the air volume?)

Pressure drop refers to the difference between the pressure values of two surfaces at the same pressure level, and it reflects the change in pressure. Pressure drop is different from pressure; I don’t think the greater the processing volume, the greater the pressure drop will be It serves merely as a numerical value for our reference, to help us assess a particular issue. For example, the pressure drop in the reactor can be used to determine the degree of blockage in the bed. What is said may not be correct; I hope experts can provide an answer.

In sulfur recovery, pressure drop is related to the volume of acidic gas. The relationship between pressure drop and flow rate should be included in textbooks on chemical engineering principles.

Pressure drop is the difference between two pressure levels; it reflects the loss of pressure energy as the fluid passes through a particular pipe or device, and it thus indicates the frictional losses in that pipe or device. 2. For the same pipeline or device, the pressure drop generated varies when the volume of fluid flowing through it differs; according to the formula, this pressure drop is proportional to the square of the flow rate of the fluid. 3. The volume of gas to be treated should vary depending on the composition of the acidic gas. Typical acid gas contains many components, such as H2S, CO2, CH4, N2, and so on. Are you referring to the amount of H2S or CO2 specifically in the acid gas? In engineering, the amount of gas being processed generally refers to the total amount of acidic exhaust gases, with the molar content of H2S or CO2 specified thereafter.

My most straightforward understanding is that, in the case of empty-board flow meters, the resistance is increased by changing the pipe diameter. Then, by measuring the pressure at the two disconnected leads, the flow rate can be determined. Active participation
