Abstract
A chemical plant may include one or more fired heaters for heating of process streams. A fired heater may include a direct-fired heat exchanger that uses the hot gases of combustion to raise the temperature of a process fluid feed flowing through tubes positioned within the heater. Fired heaters may deliver feed at a predetermined temperature to the next stage of the reaction process or perform reactions such as thermal cracking. Systems and methods are disclosed to optimize the performance of fired heaters or reduce energy consumption of fired heaters.
Claims20
A system comprising:
- a plant comprising:
- a fired heater unit;
- one or more sensors configured to measure operating information for the fired heater unit of the plant;
- a data collection platform comprising:
- one or more processors of the data collection platform;
- a communication interface of the data collection platform and in communication with the one or more sensors;
- and
- non-transitory computer-readable memory storing executable instructions that, when executed, cause the data collection platform to:
- receive sensor data comprising the operating information for the fired heater unit of the plant;
- correlate the sensor data with time data;
- and
- transmit the sensor data;
- a data analysis platform comprising:
- one or more processors of the data analysis platform;
- non-transitory computer-readable memory storing executable instructions that, when executed, cause the data analysis platform to:
- receive the sensor data from the data collection platform;
- analyze the sensor data to determine fuel input information for the plant, air information for the plant, and emissions information for the plant;
- based on the fuel input information for the plant, the air information for the plant, and the emissions information for the plant, determine an adjustment to an operating parameter of the plant to reduce energy consumption of the plant;
- and
- transmit a command configured to cause the adjustment to the operating parameter of the plant;
- and
- a control platform comprising:
- one or more processors of the control platform;
- non-transitory computer-readable memory storing executable instructions that, when executed, cause the control platform to:
- receive the command for the adjustment to the operating parameter of the plant;
- and
- adjust the operating parameter of the plant.

Non-transitory computer-readable media storing executable instructions that, when executed by one or more processors, cause a system to:
- receive sensor data comprising operating information for a fired heater unit of a plant;
- analyze the sensor data to determine fuel input information for the plant, air information for the plant, and emissions information for the plant;
- based on the fuel input information for the plant, the air information for the plant, and the emissions information for the plant, determine an adjustment to an operating parameter of the plant to reduce energy consumption of the plant;
- and
- transmit a command configured to cause the adjustment to the operating parameter of the plant.
2 more elements
A method comprising:
- receiving, by a data analysis computing device, sensor data for a sensor associated with a fired heater unit of a plant;
- based on analyzing the sensor data, determining, by the data analysis computing device, a current operating condition for an element of the fired heater unit;
- determining, by the data analysis computing device, a difference between the current operating condition for the element of the fired heater unit and a design operating condition for the element of the fired heater unit;
- based on the analyzed sensor data, determining, by the data analysis computing device, a command for adjusting the element of the fired heater unit to reduce the difference between the current operating condition and the design operating condition for the element of the fired heater unit;
- causing, by the data analysis computing device, display of the difference between the current operating condition and the design operating condition on a dashboard outlining recommendations for adjusting the element of the fired heater unit to reduce the difference between the current operating condition and the design operating condition for the element of the fired heater unit;
- and
- sending the command for adjusting the element of the fired heater unit to reduce the difference between the current operating condition and the design operating condition for the element of the fired heater unit.
