Centrifugal Compressor Operations for 21st Century Users

Attendees must bring a laptop to the course. Materials will be distributed on USB sticks and via Filex.
To equip both novice and experienced oil & gas industry professionals with state of the art practical knowledge of centrifugal gas compressors.
Centered on centrifugal gas compression, this course starts with an introduction of basic centrifugal compressor technology (including an overview of the components and nomenclature), progresses through the design and selection processes including an overview of the various analytical tools employed, and ends with project installation, commissioning and maintenance.
Entry level professionals will accelerate their understanding of the technology and how it is used in oil & gas applications. Experienced professionals will enhance their knowledge of current technologies and methods, enabling more effective project performance and/or maintenance strategies. All participants will add to their network of industry professionals and be able to share ideas, experiences and questions. The improved knowledge and expertise will provide a cost benefit to attendees’ companies:

  • By reducing errors and wasted engineering / SCM hours caused by misinterpreted nomenclature / specifications
  • By identifying possible improvements to plant performance via application of more modern centrifugal equipment; i.e., increased efficiency, reduced maintenance requirements, etc.
  • By providing a better understand of the various types of centrifugal compressors and sub-components (i.e., impellers, diffusers, bearings, seals, etc.) and the performance they provide, leading to more informed decisions when considering design requirements, selecting new equipment, deciding on a test plan, etc.


Topics Summary

  1. Centrifugal compressor types, applications, aerodynamic design and selection considerations, performance, operation and maintenance
  2. Rotordynamics and vibration analysis, bearing and seal design including dry gas seals
  3. Machinery safety – control and protection systems, diagnostics and health monitoring
  4. Project considerations – auxiliaries, piping, installation, maintenance strategies, commissioning

He has authored over ten technical papers in the area of rotordynamics and aerodynamics and has given numerous tutorials and lectures. He holds a B.S., M.S., and Ph.D. (Mechanical Engineering) from Texas A&M University.

Pete Rasmussen

Mr Peter Rasmussen has over 38 years experience in the oil and gas industry. He has broad experience and knowledge in oil and gas machinery applications and strong skills in managing and advising technology development in the oil and gas sector. Particular skills include gas turbines, high pressure centrifugal compressors and LNG refrigeration compressors. Most of his career was spent with ExxonMobil retiring as Chief Machinery Engineer (Upstream Companies). Mr. Rasmussen has coauthored papers published at LNG 15, LNG 16, Oil and Gas Journal and Texas A&M Turbomachinery Symposium. Various patents have been applied for and awarded. Mr. Rasmussen has a B.S. in Ocean Engineering from Florida Atlantic University. He is currently a Texas A&M Turbomachinery Advisory Committee Emeritus Member.

Jim Sorokes James M. (Jim) Sorokes joined Dresser-Rand (formerly Dresser-Clark) in 1976 as an Aerodynamic Engineer. He was named Supervisor of the Aerodynamics Group in 1984 and held various other positions in that group until 2004. His responsibilities included the design and analysis of all aerodynamic components in centrifugal compressors. He was also extensively involved in various compressor development projects, single stage test rig test programs, resolution of test stand and field performance problems, etc. As Manager of the Aero/Thermo Design Group (2001 – 2004), his responsibilities were expanded to include aerodynamic design and analysis activities for all Dresser-Rand turbomachinery.

In 2004, Mr. Sorokes accepted the position of Manager of Development Engineering. In that role, he managed all product and process development efforts conducted at Dresser-Rand’s Southern Tier Operations. In 2005, Mr. Sorokes was assigned to a special project that focused on improving Dresser-Rand’s position in the large turbomachinery market. His responsibilities included leading a team that developed a novel, full-scale test vehicle used to conduct research on heavy hydrocarbon applications. In 2007, Mr. Sorokes became a Principal Development Engineer responsible for the various development test programs as well as training and mentoring new engineers at Dresser-Rand.
