METHOD AND DEVICE FOR GAS ODORISING Russian patent published in 2011 - IPC B01F3/02 

FIELD: process engineering.

SUBSTANCE: invention relates to gas industry and may be used for feeding odorant into gas flow to add to safety of gas transport in pipeline. Proposed method consists in gas bubbling, determination of thermobaric parametres in bubbling process, and determination of quantitative properties of gas saturation by odorant vapors. Depending upon obtained data and measured current gas flow arte in the main pipeline, ACS computes required amount of odorised gas and inputs its into pipeline gas. Proposed device comprises liquid odorant tank, babbling tank, ACS comprising transducers bubbling thermobaric parametres, gas counter to determined has flow rate after bubbling and control unit to process received data and generate control signals to odorisation process control elements. Gas analyser and temperature controller may be incorporated with proposed device.

EFFECT: expanded range of odorised gas, possibility to be used in low-capacity gas pipelines.
