Seal oil console

The first two seal categories are usually operated dry, and the last three categories require seal oil consoles either separately or as part of the lube system. Each of these seal designs has its own characteristics and maintenance difficulties. 

For pipe sizing, process equipment sizes are required. These include types and sizes of vessels, heat exchangers, pumps, compressors, intercoolers, scrubbers, silencers, floor space of lube and seal-oil console, furnace and heater details, control and switch house arrangements. 

Seal oil consoles The hydraulic seals, located at the outer ends of the compressor shaft, receive oil from the seal oil console (Exhibit 4-5). The seal oil equipment may be configured as a console or may be designed as individual pieces of equipment. 

There are two types of seal oil systems.- gravity and pressurized. The gravity-feed seal oil system reservoir is mounted above and in view of the compressor, whose elevation is set by the compressor vendor. The sour oil traps can be integral with the lube oil console skid or located on a separate skid. The pressurized seal oil system is a pump-around facility whose components are integral to the lube oil console skid or mounted on a separate d. If components are mounted on a separate skid, placement must accommodate seal oil console operation and maintenance,... 

Space needs to be provided for the auxiliaries, including the lube oil and seal systems, lube oil cooler, intercoolers, and pulsation dampeners. A control panel or console is usually provided as part of the local console. This panel contains instmments that provide the necessary information for start-up and shutdown, and should also include warning and trouble lights. Access must be provided for motor repair and ultimate replacement needs to be considered. If a steam turbine is used, a surface condenser is probably required with a vacuum system to increase the efficiency. AH these additional systems need to be considered in the layout and spacing. In addition, room for pulsation dampeners required between stages has to be included. Aftercoolers may also be required with knockout dmms. Reference 8 describes the requirements of compressor layouts and provides many useful piping hints.
