One of the major problems with turbine lubricants is it formation of varnish. Varnish is formed from many fluid issues. In the broadest term, varnish can be considered as deposits from the lubricant - since all yield similar issues. In reality, deposits have a wide range of different chemistries depending upon the formulation of the lubricant, the application, the mode of degradation and interaction with contaminants.

Understanding the chemistry of the deposits is important for two reasons. First, the chemical make-up of the deposit provides key insights into the root cause of the deposit. Determining the cause of the deposit allows plant operators in many cases to address the root cause of the problem and prevent similar deposits from impacting their operations in the future. Second, understanding the chemistry of the deposit becomes important if one is installing a contamination control technology designed to remove the contaminant and prevent deposit formation issues. Each type of deposit may require a different treatment technology.

Presenter Biography

Dr. David Wooton an independent consultant for the lubricant industry, known on a worldwide basis as an expert in the field. He has consulted for companies in the countries all over the world. He is a Ph.D. graduate of Virginia Polytechnic Institute, where he also did a two years post-doctoral research project in analytical chemistry. He has over 30 years as an analytical chemist, with much of that time specializing in fuels and lubricant analyses and research. Over the years he has been involved in developing many methods to analyze both new and in-service fluids that are being used by test labs all over the world currently. He is best known for his expertise in FTIR analyses of in-service fluids. He is currently the Co-Chairman of ASTM D02.96.3 Committee on in-service FTIR. In 2001, Dr Wooton founded his own company (Wooton-Consulting) as an industry consultant. This job has put him in to the front line of lubricant root-cause analyses problem solving, preventative maintenance developments and lubricant analyses method developments. This background has given him a unique understanding of all areas of lubrication chemistry and the analyses of lubricants in-service. In the recent years, he has focused on the problems of varnish – where he is aiding the understanding of this problem and thrust into being one of the top world experts in the area. Dr. David Wooton has given lectures all over the world with having some 60-publications and 15-patents in the chemistry and lubricant field.
