Abstract
Methods and compositions for suppression hydrocarbon fumes, and cooking oil fumes, by applying a non-volatile organic compounds having a vapor pressure temperature greater than the vapor pressure temperature of the hydrocarbon fume constituents, or cooking oil fume constituents; said compositions may include delivery vehicles such as 70% ethanol, or thixotropic lotions, to produce remediation formulations that may be sprayed or spread onto the surfaces from which the fumes are emanating; also included is an insect repellant, comprising non-volatile organic compounds having a vapor pressure temperature greater than the vapor pressure temperature of the human pheromones and body odors with attract biting insects.
Claims15
A method for suppressing petroleum hydrocarbon fumes comprising:
- a) identification of the primary volatiles responsible for the petroleum hydrocarbon fumes
- b) determination of the vapor pressure temperature for each of the suspected primary volatiles with vapor pressures less than one atmosphere,
- c) selection of a nonvolatile organic compound with vapor pressure temperatures that are at least 30 degrees centigrade higher than the highest vapor pressure temperature of the volatile components of the petroleum hydrocarbon fumes, said nonvolatile organic compound selected from the group consisting of fatty acids, alcohols, fats, mineral and vegetable oils, waxes, silicon oils.
- d) applying the remediation formulation to the petroleum hydrocarbon.
A remediation formulation for suppressing the fumes of a petroleum hydrocarbon containing various fume producing constituents, said formulation comprising one or more fume suppressors selected from the group consisting of nonvolatile fatty acids, alcohols, mineral and vegetable oils, silicon oils with a vpt at least 30 degrees C. higher that the highest vpt of the fume producing constituents.
A method for suppressing fumes from rancid fats comprising:
- a) identification of the primary volatiles responsible for the rancid fat fumes
- b) determination of the vapor pressure temperature for each of the suspected primary volatiles with vapor pressures less than one atmosphere,
- c) selection of a nonvolatile organic compound with vapor pressure temperatures that are at least 30 degrees centigrade higher than the highest vapor pressure temperature of the volatile components of the rancid fat fumes, said nonvolatile organic compound selected from the group consisting of fatty acids, alcohols, fats, mineral and vegetable oils, waxes, silicon oils.
- d) combining a sufficient amount of the nonvolatile organic compound with a delivery vehicle therefore, selected from the group consisting of acetone, methanol, ethanol, fatty acid esters and alcohols of carbon chain length greater that 18;
- to form the a remediation formulation;
- before applying to the petroleum hydrocarbon, and
- e) applying the remediation formulation to the rancid fat.
