Knowing the concentration value of sulfur dioxide hour, how to calculate it

The daily average of sulphur dioxide must be at least 20 hours per day at an average concentration or sampling time, and the question you give does not meet the requirements of the specification. If you have to do it, add four and divide by four.

Summary. Hello, this is the hourly average of valid detection data for sulfur dioxide concentrations.

Valid detection data refers to data that excludes abnormal data, such as oversized and undervalued data.

What is the number of effective monitoring data hours for sulfur dioxide.

Hello, I have a basic understanding of your question, and I will answer it for you immediately, please wait a while!

Hello, this is the hourly average of valid detection data for sulfur dioxide concentrations. Valid detection data refers to data that excludes abnormal data, such as oversized and undervalued data.

At the same time, the state requires that when SO2 measures the hourly average, the daily detection time should be greater than 18h.

How to convert the measured and converted concentrations of sulfur dioxide.

Sulfur in. Sulfur dioxide.

The mass fraction of is 32 (16*2+32)*100%=50%.

grams of sulfur react with a sufficient amount of oxygen to produce grams of sulfur dioxide.

The mass fraction of sulfur in sulfur dioxide is 32 (16*2+32)*100%=50% grams of sulfur reacts with a sufficient amount of oxygen to produce grams of sulfur dioxide.

Summary. Sulfur dioxide is monitored in the atmosphere, and the measured amount of sulfur dioxide is divided by the sampling time during the monitoring process, which is the hourly average of sulfur dioxide.

Sulfur dioxide is monitored in the atmosphere, and the measured amount of residual sulfur dioxide is divided by the sampling time during the monitoring process, and the time is calculated as the hourly wheel leakage, which is the hourly average value of sulfur dioxide.

For example, when calculating one hour of manual SO2 monitoring, attention should be paid to the uniform distribution of sampling time, the hourly average should be the most polluted 1 hour as the sampling time, and the daily average concentration should be evenly distributed in the daily average concentration of 12 hours or 18 hours of first foot sampling time per day. The amount measured by your Wuqinqiao should be 40 minutes, according to the standard is not standardized, purely from the calculation can be converted into the amount of hours to calculate, such as the calculation result of the cover is 20mg m3, then the average hour is: 20 * 60 40 = 30mg m 3

If the one-hour average is 100, you wait.

What questions do you need me to answer for you?

64g of sulfur is 2mol, the required oxygen is 2mol, then the volume of oxygen produced is 2mol*, according to the reaction equation of one mole of sulfur and one mole of oxygen reaction to produce pure sulfur dioxide.

Best orange racket: 64g of sulfur is 2mol, and the oxygen required is 2mol, so the volume of oxygen produced is 2mol*

Sulfur is burned in air or oxygen to form sulfur dioxide, and the reaction equation is:

S+O2=Ignited Yushan=SO2

From the equation, it can be seen that 1mols and 1mololo2 react to form 1molso2, and the mass relationship is that every 32gs and 32go2 react to produce 64gso2.

As long as the amount of sulfur reacted or sulfur dioxide produced or the mass of the branch destroyed is known, the amount or mass of the O2 consumed can be calculated.

Your calculation is wrong. The result will be many times less.

2 Coal burning Sulfur content Smoke = sulfur dioxide.

"No" is because you ignore the conversion of gas mass to volume.

Room temperature, standard atmospheric pressure.

Below, the single base row is calculated in liters, and the conversion of sulfur dioxide into sulfur trioxide is not considered.

The correct formula for calculation should be:

Coal Burning Sulfur Content 2 Flue Gas = Concentration of Sulfur Dioxide.

The mass fraction of sulfur in sulfur dioxide is 32 (16*2+32) trouser fiber*100%=50%.

grams of sulfur react with a sufficient amount of oxygen to produce Huai Chung gram of Hu Ming imitation sulfur dioxide.

The converted concentration is obtained by multiplying the measured concentration by the conversion coefficient (peroxide coefficient), the oxygen content of the flue gas you measured is too high, it will cause the coefficient to be too large, and the converted concentration will be doubled several times.

Our conventional conversion factor is that the boiler presses, the kiln presses, and the power plant presses.

Then it is the measured concentration multiplied by the air excess coefficient divided by the conversion factor, which is the converted concentration.

The air excess coefficient is calculated as 21 (21-oxygen content) based on oxygen content

How to calculate the converted value of sulfur dioxide detected in the year? I have to find a master who knows this to tell you.

We generally use a constant potential electrolytic sensor for direct reading, and if we use an absorbent liquid, we need to convert the standard volume of sampling according to the working conditions, and if there is a boiler, we need to have an excess coefficient.
