Abstract
A system and method for vent gas combustion in storage tank for heavy oil production is provided. Auxiliary burners located are provided for combusting the well casing gas. A burner management system for controlling the auxiliary burners is provided which receives a gas pressure value and initiates the auxiliary burners based upon one or more threshold values when the gas pressure exceeds the one or more pressure values. An auxiliary exhaust stack may be collocated with a main exhaust stack of a tank heater for the storage tank.
Claims24
A system for vent gas combustion in storage tank for heavy oil production, the system comprising:
- a pressure sensor for determining a gas pressure value of well casing gas;
- a first auxiliary burner located for combusting the well casing gas;
- a second auxiliary burner located with the first auxiliary burner for combusting the well casing gas;
- and
- a burner management system for controlling the first and second auxiliary burners, the burner management system receiving the gas pressure value and initiating the first auxiliary burner and second auxiliary burner based upon one or more threshold values when the gas pressure exceeds the one or more pressure values.
A method for vent gas combustion from a storage tank for heavy oil production, the method comprising:
- determining a gas pressure value of well casing gas;
- initiating a first auxiliary burner to combust the well casing gas when a first on-pressure threshold value is exceeded, the first auxiliary burner is active until the pressure value is below a first off-pressure threshold;
- and
- initiating a second auxiliary burner located the second auxiliary burner to combust well casing gas when a second on-pressure threshold value is exceeded, the second auxiliary burner is active until the pressure value is below a second off-pressure threshold.
A non-transitory computer readable memory comprising instructions for controlling vent gas combustion from a storage tank for heavy oil production, the instructions which when executed a processor perform:
- determining a gas pressure value of well casing gas;
- initiating a first auxiliary burner to combust the well casing gas when a first on-pressure threshold value is exceeded, the first auxiliary burner is active until the pressure value is below a first off-pressure threshold;
- and
- initiating a second auxiliary burner located the second auxiliary burner to combust well casing gas when a second on-pressure threshold value is exceeded, the second auxiliary burner is active until the pressure value is below a second off-pressure threshold.
