2020 REFINING PROCESSES HANDBOOK PROCESS CATEGORIES COMPANY INDEX Reactor internals (cont.) Investment: With their high return on investment (on average, less than 1 yr), Shell reactor internals are a good retrofit option for any unit to help maximize profit for minimum capital expenditure. Development: Shell reactor internals' designs are the result of extensive studies and tests performed at Shell Technology Centre Amsterdam, the Netherlands. Delivery: Lead times depend on the number of beds and the complexity of the revamp. A typical delivery time is 42 weeks (shorter delivery times can be discussed). Installations: More than 1,600 reactors revamped in 550 units worldwide. References: * SASREF hydrocracker revamp: Installing Shell reactor internals in combination with catalyst beds enabled a capacity increase for the unit, higher selectivity toward middle distillates and increased cycle length. * Shell Martinez catalytic feed hydrotreater: Installing filter trays on top of the reactors to trap iron sulfide particles enabled a 300% increase in cycle length.
