ABSTRACT:
The invention provides a method of moving a pig through pipeline, the method comprising the steps of: a) introducing the pig into the pipeline; b) causing a chemical reaction between two or more reagents to produce at least one reaction product that would be in a gaseous state at STP, wherein the reagents would be in a non-gaseous state at STP; and c) introducing the gaseous reaction product into the pipeline. The invention also provides a method of moving a pig through a pipeline, the method comprising the steps of: a) introducing the pig into the pipeline; b) introducing into the pipeline two or more reagents capable of chemically reacting to produce at least one reaction product that would be in a gaseous state at STP, wherein the reagents would be in a non-gaseous state at STP.
