Abstract
Methods and systems of burning a multi-phase hydrocarbon fluid include determining a water content of the multi-phase hydrocarbon fluid, communicating the multiphase hydrocarbon fluid to a fuel port of a burner in a primary fuel flow, initiating a flame at the burner to combust the multi-phase hydrocarbon fluid, communicating an auxiliary fuel source to the burner fuel port in an auxiliary fuel flow, and controlling the primary and auxiliary fuel flows based on the water content of the multi-phase hydrocarbon fluid.
Claims24
A method of burning a multi-phase hydrocarbon fluid, comprising:
- determining a water content of the multi-phase hydrocarbon fluid;
- communicating the multi-phase hydrocarbon fluid to a fuel port of a burner in a primary fuel flow;
- initiating a flame at the burner to combust the multi-phase hydrocarbon fluid;
- communicating an auxiliary fuel source to the burner fuel port in an auxiliary fuel flow;
- controlling the primary and auxiliary fuel flows based on the water content of the multi-phase hydrocarbon fluid.
Apparatus for combusting a multi-phase hydrocarbon fluid, comprising:
- a multi-phase flowmeter having a multi-phase flowmeter inlet fluidly communicating with a source of the multi-phase hydrocarbon fluid and a multi-phase flowmeter outlet, the multi-phase flowmeter being configured to determine a water content of the multi-phase hydrocarbon fluid;
- a burner having a fuel port fluidly communicating with the multi-phase flowmeter outlet to receive an primary fuel flow of multi-phase hydrocarbon fluid, and an igniter configured to initiate a flame at the burner to combust the multi-phase hydrocarbon fluid;
- an auxiliary fuel source fluidly communicating with the burner fuel port;
- an auxiliary fuel valve disposed between the auxiliary fuel source and the burner fuel port, the auxiliary fuel valve having a first position configured to block an auxiliary fuel flow to the burner fuel port and a second position configured to permit the auxiliary fuel flow to the burner fuel port;
- a controller operatively coupled to the multi-phase flowmeter and the auxiliary fuel valve, the controller being programmed to control the primary and auxiliary fuel flows based on the water content of the multi-phase hydrocarbon fluid.
