Abstract: A method of on-line monitoring and control of monomer conversion in emulsion polymerization includes continuously balancing, as from an initialization time, the heat QIN, introduced into the reactor, the reaction enthalpy QRE introduced via the monomer feed, and the heat which has been removed from the reactor QOUT, and calculating an amount of heat which has not been removed QAD which would lead to an increase in the internal temperature and the internal pressure of the reactor in the event of a spontaneous adiabatic reaction. A check is carried out as to whether the potential adiabatic temperatures and pressures always lie below prescribed upper limits. If the upper limits are exceeded, the monomer feed to the reactor is throttled back or interrupted.

Abstract: In a process to convert emulsified polymers to polymers in an exothermic reaction, educts form a product in the presence of a passing gas. The initial reactor temperature and pressure especially are monitored and logged. The energy balance is then used to calculate the quantity of educt and product. The maximum pressure variation is calculated by monitoring the step-by-step reaction of the remaining educt quantities. The passing-gas pressure is calculated from the maximum pressure variation and the initial gas pressure. The maximum pressure variation is calculated by sub-dividing the quantities of educt and product present into quantities (n, followed by the calculation the change in reactor temperature against the quantities of residual educt and product following a known change in residual educt in an exothermal reaction. Further claimed is a process to monitor and regulate the operation of a blow-down boiler in which the product of the exothermal reaction is held in intermediate storage. The blow-down boiler is monitored online and regulated on the basis of a separate pressure calculation.

Abstract: The invention relates to a method for on-line monitoring and controlling the monomer conversion during emulsion polymerization. According to said method, a balance is continuously made, starting from an initialization point in time, of the heat amount Q?IN? fed to a reaction, the reaction enthalpy Q?RE? added by the supply with monomers and the amount of heat Q?OUT? dissipated from the reactor. A non-dissipated amount of heat Q?AD? is calculated on the basis of these values which in the case of a spontaneous adiabatic reaction would result in an increase in the internal temperature and the internal pressure of the reactor. A check is carried out whether the potential adiabatic temperatures and pressures are always within the predetermined upper limits. If said upper limits are exceeded, the addition of monomers to the reactor is slowed down or stopped.

Abstract: Procedimiento para la monitorización y el control en línea de la conversión de monómeros durante la polimerización en emulsión en un reactor, en el que a) se selecciona un momento t0 = 0 de inicialización y se le asigna al reactor para este momento una capacidad Q0 calórica inicial determinada, b) a partir del momento de inicialización se determina de manera continua la cantidad QIN de calor suministrada al reactor, la entalpía QRE de reacción suministrada y la cantidad QOUT de calor disipada del reactor, c) se calcula la cantidad QAD de calor no disipado según la ecuación siguiente: d) a partir de la cantidad QAD(t) de calor no disipada y de la temperatura T(t) interna instantánea del reactor se calcula la temperatura TAD interna máxima que aparece en caso de una reacción adiabática espontánea, y e) si la temperatura TAD interna máxima calculada sobrepasa la temperatura T(t) interna instantánea del reactor en un valor determinado, se llevan a cabo medidas, que impiden un ascenso adicionalde la cantidad QAD de calor no disipada.

Abstract: Process for continuously monitoring and controlling a chemical reactor (10) comprises using a control unit (12) which receives process-relevant parameters of the reactor, feeding calculations about the condition of the process into the reactor, and releasing control signals to the reactor depending on results of the calculations to control the process in the reactor. The calculations are produced using a calculating unit (14) assigned to the control unit and are tested and validated before the control signals are produced. Independent claims are also included for the following: (1) Device for continuously monitoring and controlling a chemical reactor; (2) Computer program with a program code; (3) Computer program product with a computer-readable medium; and (4) Reactor control unit with a monitoring and control unit.
