ABSTRACT:
Liquid natural gas is odorized with either ethyl or methyl mercaptan by initiallly mixing the odorant with a diluent and then introducing the resultant mixture into the liquid natural gas. It is preferred that the diluent have a freezing point below the boiling point of liquid natural gas. It is theorized that with the diluent the mercaptans either do not freeze or are dispersed sufficiently in the liquid natural gas to reduce the particle size of frozen odorant. In any event, the result is effective odorization of natural gas drawn from a liquid natural gas storage tank regardless of the amount of liquid and gaseous natural gas left in the tank.
