Waste Production in Reactors

Under normal operating conditions, five sources of waste production exit reactors (Smith and Petela 1991):

If unreacted feed material cannot be recycled back to the reactor, then low conversion in the reactor leads to waste for that unreacted feed.

The primary reaction can produce waste by products; for example:

PRODUCT + WASTE PRODUCT 3.7(1)

Secondary reactions can produce waste by products; for example:

PRODUCT ® WASTE PRODUCT 3.7(2)

Impurities in the feed material become waste or can react to produce additional waste by products.

The catalyst is either degraded and requires changing or is lost and cannot be recycled.
