Abstract
A dehydrogenation system includes a plurality of dehydrogenation reactors valved to operate in alternating dehydrogenation modes and regeneration modes in a timed sequence in a system cycle by way of the plurality of valves; a digital programmable controller connected to the plurality of valves for sequencing the reactors; and means for determining the productivity characteristics of each reactor over a system cycle. The digital controller is operable to re-sequence the reactors to reduce either peak productivity or productivity deltas over an initial system cycle. After resequencing, production may be increased with the more uniform productivity profile of the re-sequenced system without exceeding system limits, such as compressor operating limits.
