Auxiliary system types and functions
Forsthoffer's Rotating Equipment Handbooks, 2005Co-Authors: W.e. Bill ForsthofferAbstract:This chapter focuses on auxiliary system types and functions. There are as many different types of lubrication systems as there are lubricants. Regardless of the design variations or component type, the basic function of any lubrication system in critical equipment service is to continuously supply cool, clean lubricating fluid to each specified point at the required pressure, temperature and flow rate. The function of the Seal is to contain the process fluid. Because the function of a lubrication and a Seal system are similar they can be combined in certain instances where required flow rates, pressures and process gas characteristics permit. Extreme care must be exercised when designing a combined system containing entrained Seal gas in the Sealing Oil. As the system is combined, the Seal Oil Leakage, if it is returned to the reservoir, must be effectively degassed to assure the bearing lubricating film is incompressible. Seal Oil Leakage degassing is a primary factor in Seal Oil system safety and reliability.

Forsthoffer's Rotating Equipment Handbooks - 21 – Compressor Seal system overview and types
Forsthoffer's Rotating Equipment Handbooks, 2005Co-Authors: W.e. Bill ForsthofferAbstract:This chapter presents an overview of compressor Seal system and discusses its types. There are numerous types of fluid Seal systems as the types of Seals utilized, Sealing fluids and Sealing pressures vary widely. The supply system consists of the reservoir, pumping units, the exchangers, transfer valves, temperature control valves, and filters. The purpose of this subsystem is to continuously supply clean, cool Sealing fluid to the Seal interfaces at the correct differential pressure. The function of the Seal Oil drainer vent system is to assure that all gas side Seal Oil Leakage is directed to the drainer. The Seal Oil reservoir is sized exactly the same way as lube Oil reservoir. The only major difference between the component sizing of a Seal and a bearing is that the Seal flows across the atmospheric bushing will change with differential pressures. Many Seal system problems have been related to insufficient Seal Oil flow through the atmospheric bushing at low suction pressure conditions. It is found that liquid bushing Seals are also used for gas side Seals; however, their Leakage rate will be significantly larger than that of a contact Seal as they are essentially an orifice.

Compressor Seals for hydrogen recycle service
Sealing Technology, 2003Co-Authors: Stephen L. Ross, M. Theodore GreshAbstract:Abstract Hydrogen recycle service has presented a special challenge for centrifugal compressors and particularly the casing Seals, mainly because of contamination from process gas. This feature, reproduced with permission from the Turbomachinery Laboratory, reviews a simplified process to identify the sources of contaminants affecting both dry and wet Seals. It lists precautions for the application of dry Seals in this service, and discusses improvements to materials used for a wet Seal design. Finally, it highlights two case histories where retrofits with the improved liquid film Seal have significantly reduced sour Seal Oil Leakage rates.
