Abstract

Abstract:

In this paper, the causes of the leakage of circulating water line of the second water cooler in the methanol unit of PetroChina Dushanzi Petrochemical Company are analyzed and investigated, and some solutions are developed. By positioning the nozzle of condensate pipe deep into the circulating water pipe and turning the elbow to make the direction of process condensate consistent with that of circulating water, the erosion problem is completely solved.

Key words: methanol unit, water cooler;corrosion, leakage
