Disposal System – Steam Failure

A loss of one or more steam systems within the facility can affect steam driven equipment, resulting in multiple discharges to the disposal system. However, a loss of steam can also result in loss of heat input to the process, which may reduce the impact of equipment failures.

Determination of Credibility

Steam distribution systems are often fed by multiple sources such as boilers and waste heat steam generators. In addition, multiple steam pressures are generally present, with equipment enabling make-up of steam from higher to lower pressure systems. The potential for a loss of one or more steam pressures should be considered on a case-by-case basis.

Determination of Impact on the Collection and Disposal System

A steam failure can result in the loss of steam-driven equipment such as large compressors and pumps. The loss of large compressors (e.g., a wet gas compressor in an FCC Unit) can result in significant discharges to the disposal system. The impact of a steam failure is often mitigated by the loss of heat input to the process.
