January 10, 2018 – CyboSoft (Rancho Cordova, California), the developer of Model-Free Adaptive (MFA) control technology and products, has announced that it will conduct a training class at 4C Conference to design flare control systems to comply with EPA RSR-63.670 rules. The training class is open for all 4C conference attendees and will be held from 8am to 10am, Wednesday, April 4, 2018 at Marriott Hill Country Resort in San Antonio, Texas.
CyboSoft CEO Dr. George Cheng said, “Most refinery and chemical plants operate flares to burn off waste gas for operational and safety reasons. The deadline for refineries to comply with EPA RSR-63.670 rules is approaching quickly. Flares must maintain a minimum combustion zone net heating value of 270 Btu/scf. For air-assisted flares, the net heating value dilution parameter must be above 22 Btu/sq.ft. In order to achieve these goals, flare control systems are critical.”
Technically, flare control is very difficult because: (1) The vent gas flow can change widely; (2) The heating value in vent gas can change widely and quickly; (3) Nitrogen is often used as purge gas to maintain positive pressure in the vent pipe, making the process more complex; (4) There are large and varying time delays in the heating value control loops, and (5) The heating value process is extremely nonlinear in different operating conditions. Flares are difficult to control using conventional PID controllers. Model-based control can be costly to develop and maintain.
As illustrated in the above diagram, CyboSoft is offering a field-proven flare control solution with its CyboCon Model-Free Adaptive (MFA) control software. In this training session, we will show how to design control systems for a steam-assisted flare and an air assisted flare. We will run real-time control simulations to compare the performance when controlling combustion zone net heating value with different methods under varying operating conditions.
CyboSoft’s Flare Process Modeling and Control Simulation Software will be used in this class to demonstrate the following results: (1) A flare process is under good control where the combustion zone net heating value is above 270 Btu/scf under varying operating conditions; (2) A flare process may not meet the 270 Btu/scf requirement due to poor steam control; and (3) A flare process is not controlled well due to slow GC data. In the Q&A session, discussions should include the following: (1) RSR-63.670 regulations relating to control system design considerations, (2) Vent gas heating value measurement, (3) 15-min data block calculations, (4) How to integrate a flare control system with an existing DCS, and (5) implementation of MFA flare control systems for your specific applications.
