METHOD FOR CONTROLLING FOAMING IN A PROCESS

摘要

The invention is a method for controlling foaming in a process, the method comprising the steps of : (a) withdrawing process liquid from the process and generating gas bubbles in the process liquid by contacting the process liquid with bubble gas; (b) measuring individual lifetimes of the gas bubbles to obtain bubble lifetime data; (c) using the bubble lifetime data to predict the foam- forming tendency of the process liquid; (d) if the bubble lifetime data indicate that excess foaming will occur, adjusting the process to prevent excess foaming.
