METHOD AND DEVICE FOR DETERMINING REACTION DECAY IN HYDROCARBON CONVERSION PROCESS Russian patent published in 2005 - IPC

FIELD: petrochemical processes.

SUBSTANCE: method consists in that interaction of initial hydrocarbon and molecular hydrogen-containing gas in reaction zone in presence of catalyst results in formation of reaction product wherein concentration of oxygen is equal, close or superior to inflammability limit, after which reaction decay is determined using thus obtained signal to activate measures directed to reduce explosion risk outside of reaction zone. Reaction decay is, for example, determined from sudden increase in concentration of oxygen in reaction product stream and/or from sudden product temperature drop. A similar olefin production method is also described as well as reactor used for conversion of hydrocarbons.

EFFECT: reduced risk associated with possible explosion in equipment located outside reaction zone, where hydrocarbon oxidation occurs.
