Abstract

Abstract: Decline of steam and boiler feed water quality can cause scaling of the compressor turbine in ethylene plant, which in turn can lead to the decrease of compressor working efficiency and significant increase of steam consumption. This paper analyzes the specific reasons of compressor turbine scaling in three sets of ethylene plants, and introduces in detail the treatment methods and precautions taken for shutdown immersion cleaning, filling detergent online cleaning, saturated steam online cleaning and so forth. Meanwhile, it proposes the countermeasures to prevent compressor turbine scaling, which can provide reference for the handling of similar problems.

Key words: compressor turbine, scaling, clean, solutions
