Claim Text:
1. A method for treating a petroleum plant or equipment of the petroleum plant during a running of the petroleum plant, comprising: maintaining, during a treatment period, the petroleum plant under a production operating condition, typical of the plant itself, which includes providing fresh feed to the petroleum plant; while maintaining the petroleum plant under the production operating condition, there is carried out one or both of a) and b); a) introducing in the petroleum plant, during the treatment period, a hydrocarbon-based treatment fluid; b) varying an established feed rate, present at initiation of the treatment of the petroleum plant or equipment of the petroleum plant, which established feed rate ranges from a maximum operation rate for the petroleum plant, which is inclusive of a design rate for the petroleum plant, to a minimum operation rate which is set at a level for satisfying a minimum production operating state in the petroleum plant; wherein said introduction of a hydrocarbon-based treatment fluid and/or said variation to the established feed rate generates an additional source or sources for distillation with respect to the amount provided by the established rate present at initiation of treatment; and distilling said additional source or sources for distillation in conjunction with the distillation of a plant process stream as to form a combination distillate, and diverting a portion of said combination distillate from a flow stream of said combination distillate as to form both a flowing continuation stream of the combination distillate and a diverted stream of the combination distillate, and re-introducing the diverted stream containing combination distillate to the or another plant process stream such that the combination distillate passes within a plant treatment zone for the purpose of plant treatment.
