FIELD: process engineering.
SUBSTANCE: invention relates to method of producing odorant for natural gas from mercaptan-containing hydrocarbons. Proposed method consists in that mix of natural mercaptans is subjected to two-stage fractionation to produce vapor and liquid phases. Note here that condensed vapor phase formed at first phase conducted at 0.19÷0.23 MPa and 80÷105°C is, then, fractionated at 0.15÷0.17 MPa and 65÷85°C. Selected liquid phases of each fractionation stage are used as an odorant for natural gas.
EFFECT: higher efficiency.
