摘要：NOVELTY - The invention discloses an on-line method for measuring the density of acetylene from a outlet of the ethylene device hydrogenation reactor. It chooses some critical variables which impact this kind of density: the quantity of carbon 2 passed into the reactor, the input variables including the quantity of hydrogen and the temperature difference of the reactor, which are used for the soft measure model. The invention makes use of the nerve network model on the DCS system platform of ethylene producing device, collects samples continuously and calculates in time to measure the density of ethinefrom an exit of the ethylene device hydrogenation reactor by online.
