A New Approach to Optimizing Fired Heaters
MetadataShow full item record
Fired heaters are the largest consumers of energy in refineries and petrochemical plants. Most heaters in the industry are not operating at their peak efficiency. There could be several reasons for that. One of the common reasons is the fluctuation in the heater operating conditions and continuous need for optimization of the heater operating parameters. It is not possible to optimize the heater operation with fluctuating loads using current equipment. FIS has developed a two-prong approach to take care of this problem. The Heater Performance Index software is built into the DCS and monitors the key performance indicators round the clock. It is based on modeling of the heater and provides direction to the operators to optimize the heater. In addition, FIS has developed hardware based control schemes which can optimize the heater automatically. Optimizing the heater operation will prolong heater life and reduce NOx emissions.
