where can I get h2s leak rate

where can I get h2s leak rate

Sometimes it (H2S) increases the corrosion rate in CO2 sytems, sometimes it deceases the corrosion rate. Minimum corrosion allowance that I have seen is 1/8". Without inhibitor additions, I recorded pitting rates at 3/32" per year in a similar system.

To be conservative, I would assume the 2.0 mg/l will come out of solution. But how do i relate t...You need to assume a temperature, a wastewater flow rate and an air flow. 2 mg/l X (the waste water flow rate) will give you mass flow rate of H2S....1One way to do this is with a process simulator like HYSYS, Aspen, or PRO-II.

  • Health Problems Caused By Sewer Gas

    If inhaled, sewer gas can quickly start to cause serious issues. The nitrogen in methane and ammonia, and the hydrogen in hydrogen sulfide, will immediately start to replace the oxygen in the blood stream and in the lungs. The person who inhales sewer gas may experience asthma symptoms such as bronchial spasms when the concentrations reach 5 ppm.

    Hydrogen sulfide also occurs naturally in sewers, manure pits, well water, oil and gas wells, and volcanoes. Because it is heavier than air, hydrogen sulfide can collect in low-lying and enclosed spaces, such as manholes, sewers, and underground telephone vaults. Its presence makes work in confined spaces potentially very dangerous.
