Design And Implementation Of Refinery Equipment Corrosion And Protection System

With the increase of mining depth of petroleum resources and imported high sulfur,high acid crude oil,the trend of deterioration of crude oil is becoming more and more obvious,a serious threat to the safety and long period running of refinery.At present,low raw material design standards of some enterprises of raw device,poor adaptability,in the original(material)oily matter frequently changing circumstances,acid value and sulfur content of crude oil has exceeded the actual processing of design standards,resulting in severe corrosion of the equipment;Part of the key device for material and some enterprises upgrade is not complete,the existence of security risks;Some enterprises long-term process of low sulfur and acid crude oil,corrosion control measure device is not perfect and corrosion of low level management,When processing high sulfur,high acid crude oil after the transformation,although the hardware equipment to meet the processing of high sulfur,high acid crude oil demand,Many defects still exist but corrosion control technology,corrosion management software,the accident unit corrosion prone.Therefore,in order to better solve the corrosion problem of refinery,we developed oil refinery equipment corrosion protection system,to ensure the safe and stable operation of production equipment for oil refining enterprises.Refinery equipment corrosion and protection system of this paper uses the object-oriented design method of the system is divided into oil refinery equipment corrosion case base resistance,the three part forecasting system corrosion of metal material database,corrosion mechanism and life.Refinery equipment corrosion is the main failure case database:a large number of cases of domestic and foreign oil refining device corrosion sorting through the collection,provide corrosion case query service for the oil refining enterprises;Corrosion of metal material database:is mainly to provide routine performance,many kinds of metal material corrosion performance of query for oil refining enterprises,as well as providing refinery equipment selection advice and knowledge service;Prediction of corrosion mechanism and the service life of the system:mainly is carries on the corrosion mechanism analysis,safety assessment and remaining life prediction of suffered corrosion effect of refinery equipment.Refinery equipment corrosion and protection system of this paper is to achieve the desired results,running smoothly,to the positive role in the prevention of corrosion work refining enterprises,has been refining enterprises recognition.
