The Crude Unit Corrosion Guide was written for plant operators, process engineers, metallurgists, maintenance engineers, inspectors, and all others who deal daily with corrosion and fouling issues. In the past, most refineries also employed corrosion engineers. That position has all but disappeared as the experienced practitioners moved on, retired, or were replaced by engineering contractors, equipment builders, and process additives suppliers.
Like the earlier editions of the Guide, this revised 3rd Edition is based primarily on the experience of the author, Joerg Gutzeit, M.S.ChemEng, in dealing with all aspects of corrosion and fouling in crude units. The Guide also reflects the Industry’s consensus experiences reported at past meetings of the NACE STG34 Committee on Petroleum Refining and Gas Processing (formerly T8 Committee on Refining Industry Corrosion) and the API Subcommittee on Corrosion and Materials. Diluent recovery units (DRUs) and vacuum distillation units (VDUs) of bitumen upgraders are quite similar to crude units with similar corrosion and fouling issues and are now included in the discussions where appropriate. In addition to corrosion and fouling issues with the usual 3 or 4 crude types, the Guide now covers various bitumen-derived crudes, including synthetic crude, dilbit crude, synbit crude, and shale crude all of which have come to market in recent years.
In many ways, refinery corrosion and fouling control remained more “art than science.” Despite college-level courses in corrosion and materials science and ongoing efforts by NACE, API, and ASM, few resources for practical training on plant corrosion and fouling control are available. In recent years, process simulation (PS) and risk-based inspection management (RBIM) software has been very helpful for identifying and ranking critical components on which to concentrate future inspection and maintenance efforts. However, a certain amount of expertise is still required to facilitate reliable data input and assessment. The Guide attempts to present in compact form what the author considers the most important aspects of corrosion and fouling control in the atmospheric and vacuum sections of crude units and the corresponding sections in bitumen upgraders. Various chapters deal with general corrosion characteristics of different feedstocks; materials of construction (metallurgy); corrosion and fouling monitoring; feedstock preparation by tank settling, desalting, and caustic injection; and the types of damage seen in major components. Other chapters cover specific topics, including preheat exchanger fouling; high-temperature corrosion and fouling by organic sulfur compounds and naphthenic acids in fired heaters, transfer lines, and distillation columns; low-temperature corrosion and fouling by inorganic chlorides in the top of columns and in overhead systems; organic chloride problems; and various issues with neutralizer, corrosion inhibitor, and water injection systems.

Process equipment and piping in chemical and petrochemical plants and petroleum refineries have to be cleaned periodically as part of normal maintenance operations to remove fouling that interferes with process flow, heat transfer, or other operations. Cleaning is also necessary to allow safe personnel entry prior to equipment inspection, repairs, or modifications. Most cleaning operations are expensive and time-consuming and need to be planned, budgeted, and carried out in a timely fashion to ensure minimum interference with normal process or maintenance operations. Certain process equipment and piping may also have to be cleaned prior to being put into service for the first time. Such pre-commission cleaning removes rust, dirt, and other debris that formed or entered during fabrication, shipment, or erection, and that are likely to cause damage after start-up. This manual, which was prepared under MTI Project 69, covers cleaning of process equipment and piping in chemical plants, petrochemical plants and petroleum refineries. Practical information and guidance is provided for plant engineers and operators who, from time to time, are charged with planning various cleaning operations that will be carried out either by in-house maintenance personnel or outside cleaning contractors. Sufficient information is given to enable the nonspecialist to either propose cleaning procedures or evaluate cleaning procedures proposed by others. The manual enumerates a multitude of factors that need to be considered before a cleaning operation is started, including timing, alternative methods, costs, manpower requirements, safety concerns, and waste disposal issues.
