COURSE OVERVIEW:

Advanced dry gas seal design and selection represent the pinnacle of sealing technology for high-speed centrifugal compressors and rotating equipment in the oil and gas sector. This course provides an in-depth exploration of the aerodynamic principles that allow seal faces to operate without physical contact, utilizing a thin film of gas. Understanding the nuances of groove geometry, face materials, and the physics of gas films is critical for ensuring the integrity of high-pressure process loops.

The scope of this training involves a detailed examination of seal configurations, including tandem, double, and triple seal arrangements, and their respective applications in toxic or flammable gas services. Participants will investigate the mechanical design constraints such as centrifugal distortion, thermal gradients, and the impact of varying gas compositions on seal stability. The coverage extends to the selection of primary and secondary sealing elements, focusing on elastomeric and non-elastomeric materials suited for extreme temperature and pressure fluctuations.

Furthermore, the course addresses the critical integration of dry gas seal support systems, specifically gas conditioning skids, filtration, and control panels. It delves into the selection criteria based on API 617 and API 692 standards to ensure global compliance and operational reliability. By focusing on both theoretical fluid dynamics and practical selection matrices, the course equips professionals with the expertise to minimize leakage and prevent catastrophic seal failures in critical machinery.

COURSE OBJECTIVES:

After completion of this course, the participants will be able to:

1. Explain the aerodynamic lifting principles of spiral groove dry gas seals.
2. Differentiate between tandem and double seal arrangements for specific gas types.
3. Analyze the impact of gas dew point on seal face stability and longevity.
4. Select appropriate face materials such as Silicon Carbide and Tungsten Carbide.
5. Evaluate the requirements for seal gas filtration and conditioning skids.
6. Interpret API 692 standards for the design of dry gas seal systems.
7. Calculate the leakage rates for various seal sizes and operating pressures.
8. Assess the risks of "slow roll" and "turning gear" operations on seal life.
9. Design effective separation seal systems to prevent oil migration into gas faces.
10. Implement troubleshooting protocols for high primary vent pressure alarms.
11. Optimize the selection of O-rings and polymer seals for explosive decompression resistance.
12. Conduct a technical review of seal manufacturer data sheets and test reports.
13. Manage the preservation and storage requirements for spare dry gas seal cartridges.
14. Troubleshoot common failure modes related to liquid contamination and debris.

TARGET AUDIENCE:

This course is intended for rotating equipment engineers, maintenance superintendents, mechanical seal specialists, and plant engineers involved in the design, selection, and reliability management of centrifugal compressors.

TRAINING COURSE METHODOLOGY:

A highly interactive combination of lectures, discussion sessions, and case studies will be employed to maximise the transfer of information, knowledge, and experience. The course will be intensive, practical, and highly interactive. The sessions will start by raising the most relevant questions and motivating everybody to find the right answers. The attendants will also be encouraged to raise more of their questions and to share in developing the right answers using their analysis and experience. There will also be some indoor experiential activities to enhance the learning experience. Course material will be provided in PowerPoint, with necessary animations, learning videos, and general discussions.

The course participants shall be evaluated before, during, and at the end of the course.

COURSE CERTIFICATE:

National Consultant Centre for Training LLC (NCC) will issue an Attendance Certificate to all participants completing a minimum of 80% of the total attendance time requirement.
