About This Course

LNG plants and other petrochemical plants are built to bring a return on investment to their investors through their safe operation. Their designers and engineer-led operators require technical knowledge to ensure these facilities are safe and dependable.

This training covers LNG technologies at both a technical and human resource development level. This training is needed to help you design, operate, and maintain an LNG facility; however, many LNG topics can also apply to other petrochemical plants. It is intended to give the learner the intermediate technical knowledge needed to make informed planning, maintenance, and operating decisions to ensure plant safety, reliability, and efficiency.

In the ten lessons, details will be given on the operation of an LNG plant, refrigeration systems for liquefying, and the thermodynamics involved in producing, storing, transporting, and re-vaporizing LNG.

This is the seventh of the ten lessons. The topics covered in this lesson include understanding:

  • The volatility and behavior of zeotropic mixtures (components of LNG)
  • The relationship between various LNG components' molecular mass, volatility, and temperature
  • The weathering of LNG that does not contain nitrogen, including its effect on LNG density
  • The weathering of LNG that does contain nitrogen, including its effect on LNG density
  • In-tank convective currents of LNG with and without nitrogen in the LNG
  • The impact of hydrogen injected into LNG liquefier feed gas
  • The FERC guidelines on higher heating value, wobbe number, and inerts on interchangeability
  • Understanding LNG blending and sendout stabilization
  • Nitrogen-induced rollover phenomenon
  • Removal of nitrogen from LNG before storage
  • Removal of hydrogen from LNG before storage
  • The phenomenon of hydrogen stress corrosion cracking

** Mechanical Engineering and Process Engineering ** Dr. Vitale is a graduate of NYU Tandon School of Engineering (formerly NY Polytechnic University) with a B.S., M.S., and Ph.D. in Mechanical Engineering and an M.S. in Civil Engineering. He has been licensed as a P.E. in 6 states and keeps his P.E. licenses active in New York, Pennsylvania, and New Mexico. Dr. Vitale has worked in the natural gas and LNG industry for over 50 years. In 2004 he retired as Vice President and Chief Engineer over Gas Engineering and 28 Production facilities for KeySpan Energy across New York City, Long Island, Rhode Island, Massachusetts, and New Hampshire. During his employment with KeySpan, he often taught Thermodynamics, Heat Transfer, Fluid Dynamics, and other energy courses at NY Polytechnic University. From 2004 to the present, Dr. Vitale has focused on consulting for the Gas Industry with a specialty in training the industry’s human resources on how to make safety and reliability their major focus through understanding the technologies. More than half of Dr. Vitale’s consulting has been focused on training Liquefied Natural Gas (LNG) Operating personnel on generic and site-specific operations of their plants. Dr. Vitale has generated and delivered training materials for import terminals, export terminals, peak shavers, and portable LNG facilities. His courses have been both open-enrollment and plant-specific. He has trained clients in the U.S., Canada, Mexico, South America, Europe, Mid-East, and China. Dr. Vitale has also provided expert testimony for justifying asset (pipeline and service) replacement programs and new facilities (LNG or pipeline or compressors) for system reinforcements to meet the peak-day demands of the industry’s customers. Dr. Vitale’s passion is to train Gas Operators on their gas systems' safe, reliable, and efficient operation and develop a continuous learning culture.
