    摘要: The present invention is related to an online early warning detection system of runaway initiation in a batch chemical reactor, comprising means (12) for measuring the temperature in the reactor and/or its jacket at different points and at different instants, and means (3 to 5) for deducing therefrom criteria for dangerous runaway conditions. According to the invention, said deducing means (3 to 5) include means (5) for defining the area evolution of the system in the reconstructed phase space according to the formula div [F(t)] = (1/t) ln area(P1 t+Δt , P2 t+Δt , P3 t+Δt ) area (P1 t , P2 t , P3 t ) wherein are signifies the area of the parallelogram given by points P1, P2, P3 at the instant t and t+Δt respectively, and means (8, 9) for launching an alarm, if div[F(t)] > 0.
