Process to monitor progress if an exothermic reaction in the presence of a passing gas, by monitoring changes of temperature and pressure against presence of educt and product

摘要

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.
