Abstract: A parallel chemical production system producing a desired product by operating a plurality of reactors in parallel. The fluidic properties of each of the reactors are identical to the properties of a test reactor employed to determine conditions for producing the product, to facilitate scaling up production. In one embodiment, the production system is configured such that at least one reactor is always offline for cleaning, servicing, and use as a backup. If sensors detect less than optimal conditions in any reactor, the reactor is taken offline and serviced, while a previously designated backup reactor is placed online to maintain continuous production. Another aspect involves arranging the reactors in a concentric configuration to facilitate equal fluid distribution.
