Novel Coating Approaches for High Temperature Corrosion Protection in Chemical and Petro-chemical Industries
Currently the use of coatings at high temperatures in chemical and petrochemical industries is limited to only rather few very specific situations. This may be due to the fact that in a couple of cases negative experiences were made with coatings or that suitable coatings for a specific protection situation were not existing. Recently new activities have been started aiming at two aspects. The first is to develop coatings that can suppress coking and metal dusting attack “at the roots” by a catalytic effect preventing disintegration of the CO or CxHy molecules in the process gas environment. The second is a new slurry coating route that allows application of the coating even under air environment and on-site for large structures. The resulting coatings rely on the protective effect of alumina scale formation on the surface and, thus, can have “universal” protective character in many chemical and petrochemical high temperature process environments. The presentation describes the two new development routes in some detail and presents first structural applications for large scale components in plant technology.
Professor Michael Schütze is advisor and evaluator in several national and international research program and research institute. He obtained his PhD in Engineering Science from RWTH Aachen University Germany. Michael worked as research associate in high temperature materials group at karl-winnacker-institute till 1991. He assigned as director in karl-winnacker-institute from 1996-2012. In 1998, he was appointed as professor in RWTH Aachen university. Since 2012 to date, he is a chairman of the executive board of DECHEMA in Frankfort. Michael worked as chairman of the Gordon research conference on corrosion in 1999. Also, he worked as president for European federation of corrosion (EFC) from 2005- 2008 as well as president of the world corrosion organization (WCO) from 2007-2010 and ISO convener from 2002-2015. Professor Michael Schütze is an editor and member of editorial board of 6 technical /scientific journals.

on self-healing materials.
Self-Healing Materials: an alternative strategy to make materials and installations last longer.
For centuries materials scientist have tried to improve the performance and durability of materials and installation by making materials with a high resistance to damage. While the strategy certainly works and has brought us, it has its limitations as damage essentially is unavoidable and any accidental local damage greatly accelerates the rate of damage formation. Unlike man-made materials, materials in nature sometimes derive excellent durability not by being very damage resistant, but by being able to autonomously heal cracks, scratches and other forms of damage. In the talk the concept of self-healing materials and the various strategies for the various classes of self-healing materials will be presented. Special attention will be given to materials relevant to the oil and gas industry.
Sybrand van der Zwaag is full professor at the faculty of Aerospace Engineering of the Delft University of Technology in the Netherlands and scientific director for the national (Dutch) program on self-healing materials. He obtained his MSc degree in Metallurgy from the TU Delft and a PhD in Applied Physics from Cambridge University (UK).
Before returning in 1992 to Delft he worked for 10 years in the polymer industry. He has published over 400 paper and 2 books on self-healing materials.

Corrosion Management of sour Production Facilities: Recent lessons learnt
A 1st stage of the lecture will summarize few recently learnt lessons on several corrosion and corrosion control subjects in the domain of sour production facilities:
- Though H2S cracking phenomena are now well known and subjected to international standards and to specifications, a brief highlight will be made on new limits which continue been reached. Such limits require developing new understanding, new engineering approaches and new materials: science and technology are still far from an end in this domain,
- Weight loss corrosion in sour conditions is by far a less documented topic than cracking topics. On the other hand a very substantial progress has been made over the last 10 years. An emphasis will be given to these progresses and to their application to new and mature fields.
From this technical background, the 2nd part will elaborate on more managerial aspects of the corrosion control approach of operating companies: how to assure that the existing knowledge in corrosion is well available, shared and finally applied? How to prevent reinventing the wheel and capitalizing from previous experiences?.
A particular focus will be made on three aspects, which should be part of a formalized Corrosion Management plan:
- Developing knowledge and practices both from the combination of basics in corrosion and from real experience,
- Assuring a regular corrosion training not only to but also from corrosion specialists,
- having a long term Competence and Carrier development plan.
Such actions among others are at the essence of the development of future generations of experienced corrosion engineers and experts whom our industry needs.
Michel Bonis is involved in Corrosion Control and Materials activities in the Oil & Gas sector since 1979, beginning as a PhD student during 3 years in the sweet corrosion area.
Working first as an R&D Engineer, he moved to Field Operations on sour oil and gas fields for 3 years, then to the Technology Department at Head Quarters of Elf, then Total Companies. He is now a Discipline Advisor in corrosion in the Exploration- Production branch of Total.
