Method for checking back promotion of return flow of reactant of catalyst in conveying and dosing system, involves providing flow rate measurement in discharge line and return flow path to check back promotion of return flow

摘要

The method involves promoting liquid reaction product from tank (10) and dosing reagent through pressure line (16). A feed path is provided with feed pump (11). A return flow path (17) is provided with return pump (22). The back promotion of reactant from metering module (19) is provided after stopping conveying and dosing system. The back promotion check of return flow is performed with respect to flow rate measurement in pressure line and in return flow path. Independent claims are included for the following: (1) conveying and dosing system; and (2) computer program for checking back promotion of return flow of reactant of catalyst in conveying and dosing system.
