Abstract

The present disclosure provides a method for operating a urea plant comprising an urea synthesis section, wherein the synthesis section comprises at least one high-pressure process line, a flushing system fluidly connected to the at least one high-pressure process line, a first high pressure flushing pump configured to direct an aqueous solution to the flushing system, and at least one sensor for measuring a process variable, wherein the urea plant comprises a second high-pressure flushing pump configured to direct an aqueous solution to the at least one sensor for measuring a process variable, and wherein the method further comprises continuously directing an aqueous solution from the second high-pressure flushing pump to the flushing system. The present disclosure further provides an assembly comprising a flushing system, a first high pressure flushing pump fluidly connected to the flushing system, a second high-pressure flushing pump and at least one sensor for measuring a process variable in the synthesis section, wherein the second high-pressure flushing pump is fluidly connected to the flushing system and to the at least one sensor and configured to provide an aqueous solution to the flushing system and to the at least one sensor.
