Method and device for controlling odor and vapor

A trap to control gas and vapor emissions, said trap comprising:

• A) a first housing, said first housing having an entry port for gases and vapors, a top, sides, and bottom;
• B) a secondary housing mounted in an interior of said first housing, said secondary housing having partial vertical walls that do not rest on a bottom of said first housing;
• C) a water trap located in a bottom of said first housing;
• D) an exit port through said top of said first housing;
• E) a siphon tube extending from said water trap to said exit of said first housing;
• F) a barrier fluid contained in said first housing wherein the volume of said barrier fluid exceeds a bottom edge of said partial walls of said secondary housing wherein said barrier fluid is selected from the group consisting of:
• a) an organic fluid composition selected from the group consisting of:
• i) hydrocarbon oil,
• ii) polyglycol oil,
• iii) paraffinic oil,
• iv) aromatic oil, and
• v) poly-alfa-olefinic oil;
• b) polysiloxane fluid polymer compositions having the average formula
• RMe2SiO(Me2SiO)x(MeRSiO)y(R*SiO3/2)zOSiMe2R
• wherein Me denotes a methyl radical and R denotes a methyl radical, a hydroxyl radical, a phenyl radical, an alkyl radical with 2-6 carbon atoms, an alkenyl radical with 2-6 carbon atoms, a halogenated alkyl radical with 1 to 6 carbon atoms, or a silacyclopentene radical;
• R* is the same as R, or represent a siloxane branch represented by the formula RMe2SiO(Me2SiO)x-;
• the average value of x and y varies from 1 to 250, and the value of z is from 0-10;
• wherein said barrier fluids have a Melt Transition Temperature (Tm) less than −25 degrees centigrade, a Vapor Pressure (Vp) of less than 20 mm Mercury (Hg) at 40 degrees centigrade, a viscosity of 1 to 10,000 centipoise at 25 degrees centigrade, a Specific Gravity (SG) of less than 1 at 25 degrees centigrade and a goniometric static surface water contact angle of greater than 100 degrees.
