Abstract
Systems and methods of injecting hydrate inhibiting chemicals into a gaseous fuel line of a burner are described. One system includes: an oilfield burner; a gaseous fuel line connected to the oilfield burner; a storage tank containing hydrate-inhibiting chemicals; a hydrate-inhibiting chemical supply line connected between the storage tank and the gaseous fuel line; and a control valve connected to control flow in the hydrate-inhibiting chemical supply line in response to the operation of the oilfield burner. A kit may be provided with at least the hydrate-inhibiting chemical supply line and control valve.
