Process Equipment Specification and Selection
SUMMARY
Process design as well as equipment specifications and selection can cause unintended problems following unit revamps. Identification of the true constraints may result in significant capital savings.
TEXT
Frequently, the consequences of process and equipment design specifications only become apparent after startup when design basis or reliability expectations have not been met, resulting in unintended post-revamp problems. Three cases discussing where such problems have been observed involve:
- Case study 1: Insufficient wet gas compressor capacity
- Case study 2: High FCC gasoline sulphur
- Case study 3: Main fractionator coking...
