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 monitoring exothermic reactions in a reactor, whereby at least two starting materials react exothermically to giv e at least one product and at least one gas is present in the reactor under normal operating conditions or on a runaway occurring, comprising the following method steps: A) measurement and recording of a starting temperatu re and a starting pressure in the reactor, B) calculation of the amounts of products and starting materials present in the reactor from an energy balanc e, C) calculation of a maximum pressure increase on a step reaction of the amounts of starting materials present, D) calculation of a runaway pressure from the maximum pressure increase as calculated in step C) and the starting pressure as measured and stored in step A).
