Refinery throughput (capacity)
Refinery throughput: the capacity for refining crude oil over a given period of time, usually expressed in barrels.
Refinery capacity is the stream day capability to process inputs to atmospheric distillation units under normal operating conditions, less the impact of planned shutdowns for regular repair and maintenance activities averaged over an extended period of time.
