Conversion between dry and wet forms of coke oven gas
Thread Content
Gentlemen, given the components and volume of coke oven gas, it is necessary to determine whether the gas is dry or wet when selecting a compressor. If it is dry, how can it be converted to a wet form? And how is the content of saturated water calculated?
Could some kind-hearted expert give me some advice? ?
At a certain temperature, the pressure of saturated water vapor is first determined, and then the total gas volume is calculated based on the amount of dry gas.
Sir, could you explain it in more detail? Thank you!
The saturated vapor pressure of water at the operating temperature is determined; the total operating pressure minus this saturated vapor pressure gives the partial pressure of the dry gas. The total amount of wet gas is then calculated based on the flow rate of the dry gas. From this, the water vapor content can be determined.
The determination of whether it is dry gas or wet gas is based on the previous treatment process; normal coke oven gas should contain water.
The data used for analysis is on a dry basis. The moisture content in coke oven gas is essentially saturated; it is calculated based on the temperature at the compressor inlet (30–40). We use a moisture content of 4.0113%, which means that the other components account for 95.9887%. Multiplying the dry-basis components by 95.9887% gives the proportion of each component on a wet basis
You can check the saturated steam table at the current temperature and pressure to find the specific moisture value
