The design institute has specified 80 KPa for me now; as far as I remember, it’s usually around 50 KPa. Is a pressure booster fan built into your acidic gas sulfur combustion furnace?
The pressure here is around 75 kPa
Hello, where are you from? Who designed it for you?
Pressure booster fan? Generally, air is supplied in the process of producing sulfur from acidic gases; therefore, fans are required. I’m not sure what you mean by \"pressure boost fan\"
The booster fan I’m referring to is used to increase the pressure of acidic gases
Typically, the operating pressure of sulfur recovery units is designed based on the pressure that can be achieved at the fan outlet, which is generally 70 kPa.
Our process is not effective; the acidic gas supplied from the upstream stage is already under pressure – during normal operation this pressure is 50-60 kp, while the system’s pressure interlock threshold is set at 80 kp.
How far is your upstream section from the sulfur unit? Did pressure buildup occur in the upstream section during operation? What is their operating pressure?
It is estimated that the design institute set the pressure at 80 KPa in order to account for issues such as increased system pressure drops resulting from subsequent exhaust gas treatment processes (such as enhanced alkaline washing or purifying the exhaust gas before sending it to low-temperature methanol washing for recovery). Here, we do not have sulfur production fans; instead, air is supplied directly from the air separation unit and depressurized to 0.4 MPa (G) for sulfur recovery, which provides a relatively stable condition. Low-methanic acid gas generally does not require a pressure booster fan, as the pressure supplied by the low-temperature methanol washing unit is already 0.15 MPa (G), which is equivalent to 150 KPa.
I have never used a pressure booster fan before; in the coal chemical industry, we use gas as fuel, and therefore a gas pressure booster is required
Hello, I’m referring to the booster pump on the acidic gas pipeline
