FIELD: inspection devices.
SUBSTANCE: inspecting devices for tightness that can be used to monitor tightness of shut-off valves of an installation for adsorption-type unit providing gas treatment before transportation, filled with adsorbents containing aluminium oxide. Concentration of the indicator substance in natural gas on both sides of taps and valves is compared. In this case, dimethyl alcohol is used as an indicator substance, which is formed during regeneration of adsorbents from methanol contained in natural gas.
EFFECT: monitoring tightness of the shut-off equipment of an adsorption-type unit for natural gas treatment before transportation, filled with adsorbents that contain aluminium oxide.
