  • SOP Hazardous and Highly Toxic Gases PennEHRS

    Hazardous gases are those gases that are sufficiently toxic and/or reactive to meet one of the definitions given below. They include acutely toxic, corrosive, flammable, dangerously reactive and oxidizing gases. Inert compressed gases such as nitrogen, argon, and carbon dioxide are not considered quot;Hazardous Gasesquot; for the purpose of this SOP.

    Dissolved gases. Small amounts of dissolved gases have little effect on flow rate or other pumping requirements. If large amounts of gas enter the liquid through piping leaks or as a result of vortexing in vessels, the specific gravity of the liquid will decrease. Dissolved gases can also reduce the amount of NPSHA at the pump suction.

    Liquefied gas means a substance is a gas at room temperature and atmospheric pressure, but the pressure or temperature has been modified until the substance changes phase into a liquid. Since the volume of a gas varies directly with temperature and inversely with pressure, gas can be liquefied by cooling or compressing.

    The difference between pump suction pressure and vapor pressure is the net positive suction head (NPSH). For cases in which the liquid contains no dissolved gases, the vapor pressure determination is straightforward. With dissolved gases, the situation is more complicated, because vapor pressure data for such systems are usually not at hand.
