How is mercaptan stored?
Methyl mercaptan should be stored in cool, well ventilated places. The main toxic effect of exposure to methyl mercaptan is irritation of the respiratory airway, skin, and eyes.
How do you dispose of ethyl mercaptan?
Ethyl mercaptan is a waste chemical stream constituent which may be subjected to ultimate disposal by controlled incineration (2,000 deg F) followed by scrubbing with a caustic solution.
How is ethyl mercaptan made?
Preparation. Ethanethiol is prepared by the reaction of ethylene with hydrogen sulfide over a catalyst. The various producers utilize different catalysts in this process. It has also been prepared commercially by the reaction of ethanol with hydrogen sulfide gas over an acidic solid catalyst, such as alumina.
Is mercaptan a hazardous material?
* Methyl Mercaptan is on the Hazardous Substance List because it is regulated by OSHA and cited by ACGIH, DOT, NIOSH, DEP, NFPA and EPA. * This chemical is on the Special Health Hazard Substance List because it is FLAMMABLE.
What is the use of ethyl mercaptan?
It is used as an additive to odorless gases like butane, propane, and petroleum to give them a warning odor. It is also used in the manufacture of fungicides, pharmaceuticals, insecticides, resins, and other chemicals.
Is ethyl mercaptan a VOC?
Results showed that short-term averages of three odorous VOCs, namely ethyl mercaptan, methyl mercaptan and hydrogen sulfide, exceeded their odor thresholds, which are reported to be 0.022, 0.138 and 11.1 microg/m(3), respectively, at several points within the domain.
How much mercaptan is added to propane?
The general industry practice is to place 1.5 pounds of ethyl mercaptan per 10,000 gallons of propane.
Why is ethyl mercaptan added to LPG?
Ethyl Mercaptan is Used in LPG Because of its Stability Over Time. Ethyl mercaptan (not methyl mercaptan) is used in LPG as an odourant to generate the telltale smell. Ethyl Mercaptan will maintain the chemical equilibrium across the liquid and vapour space.
What is ethyl mercaptan pronunciation?
zep-TEM-ber.
What is mercaptan in natural gas?
Mercaptan is also known as methanethiol and is a harmless but pungent-smelling gas which has been described as having the stench of rotting cabbages or smelly socks. It is often added to natural gas, which is colorless and odorless, to make it easier to detect.
What is merox process?
Merox is an acronym for mercaptan oxidation. It is a proprietary catalytic chemical process developed by UOP used in oil refineries and natural gas processing plants to remove mercaptans from LPG, propane, butanes, light naphthas, kerosene and jet fuel by converting them to liquid hydrocarbon disulfides.
What ppm can you smell propane?
The gas has a smell at an odor threshold of 1 ppb, and OSHA has a Permissible Exposure Limit for mercaptan of 10 ppm. See more in the FAQ in About Gas Odorization.
