POSITION SUMMARY

Nature and Scope

Air separation plant (ASU) is a continuous process plant operating throughout the year with short period of plant outage for maintenance activities, onstream status should be at least 98%. Besides atmospheric air, energy, in the form of electrical power or steam, is the other main component required to produce ASU products. There are many different electrical equipment necessary for continuous on-stream operation of the whole plant, from large power medium voltage induction motor, medium voltage air and gas insulated cabinet switchgears, synchronous generator, low voltage variable frequency drives, and many other electrical loads powered from low voltage power control centers and medium voltage switchgear lineup.

One other major facility is hydrogen generation plant, which is electrically classified as a hazardous area while the air separation plant is classified as safe area. Electrical equipment installed throughout the plant, as well as in electrical classified hazardous area, would comply with relevant international standards, and Air Products electrical equipment standards and specification.

The actual electrical power supply configuration may differ from plant to plant, but in general, electrical power is supplied to the plant at medium voltage level, transform down to working level voltages for operation of induction motors and other loads. In some plants, standby diesel generator provides the backup power necessary for continuous operation of pipeline equipment. This configuration is equally applicable in air separation unit and hydrogen generating plants.
