摘要
A system for prevention of hydrate formation has a manifold, a production piping communicating with the manifold, a chemical injection line positioned in heat exchange relationship along the production piping, and a fluid delivery system connected to the chemical injection line for passing a heated fluid through at least a portion of the chemical injection line. The chemical injection line has a first portion affixed to a surface of the production piping and a second portion extending outwardly therefrom. The fluid delivery system is in communication with the second portion of the chemical injection line. The chemical injection line extends in a U-shaped pattern or in a spiral pattern around an outer surface of the production piping.
