Effective Control of Off-Gas Processes Presented By Cecil Smith

Video: Introduction Of Off-Gas Process

The off-gas process is an excellent example of a multivariable process control application. The focus must be on the control issues, not complex process technology that is likely to be proprietary. The simplicity of the off-gas process fits these requirements. The process involves heating air and mixing air streams of different temperatures. But even for simple processes, issues can arise regarding the performance of the process controls.

Video: Single-Loop Control Configuration For Off-Gas Process

This video presents the single-loop control configuration for the off-gas process. The configuration consists of four loops that must be tuned one at a time. A sequence will be proposed for tuning the loops, but the actual tuning will be the subject of subsequent videos.

Video: Tuning the Hot Air Loops

This video examines the tuning of the hot air pressure and hot air temperature controllers. The loops will be tuned in the sequence suggested in the previous video but not as part of plant start-up. Instead, the process is operating and each controller has been previously tuned. The objective is to assess how well each loop is tuned, and make adjustments if appropriate.

Video: Tuning the Scrubber Duct Inlet Temperature Loop

This video examines the tuning of the scrubber duct inlet temperature controller. Previous videos examined the hot air pressure, hot air temperature, and the bag house inlet temperature controllers. Our starting point is all previously tuned controllers on auto.

Video: Understanding the Behavior of the Off-Gas Process

Following a description of the off-gas process, a single-loop control configuration is proposed, followed by a discussion of tuning the individual loops.

Video: Interaction in the Single-Loop Configuration

This video examines the degree of interaction between the scrubber duct inlet temperature loop and the remaining loops in the single-loop configuration.

Video: Alternate Control Configuration for Off-Gas Process

The temperature of the hot air is determined by the opening of the fuel gas valve and the opening of the fresh air damper. Based on the process understanding from previous videos, this video proposes alternate control logic for these two final control elements.

Video: Ratioing Fresh Air and Fuel Flow to Furnace

The scrubber duct inlet temperature controller adjusts the opening of the fuel gas valve. Opening only the fuel gas valve affects the hot air temperature. To increase the heat input at a constant hot air temperature, both the fuel gas valve and the fresh air damper must open. This video presents a ratio control configuration that enables the scrubber duct inlet temperature controller to simultaneously change the openings of the fuel gas valve and the fresh air damper, the objective being to minimize the effect on the hot air temperature.

Watch Now

Video: Characterization Function for Implementing Ratio Control

The control configuration proposed in the previous video included a characterization function whose purpose can be stated as follows: Given a value for the fuel gas valve opening, determine the fresh air damper opening required to give a hot air temperature of 210°C. The focus of this video is obtaining data points for this characterization function.

Video: Configuration Issues for PID Blocks in Alternate Control Configuration

When blocks such as summers, selectors, etc., are inserted between the output of the PID block and the final control element, some configuration issues must be addressed for the PID block.

Video: Commissioning the Ratio Controls for Fresh Air and Fuel Flow

The subject of this video is commissioning the ratio configuration that uses the characterization function.

Video: Controls for Hot Air Dampers in Alternate Control Configuration

This video proposes controls for the hot air pressure and the bag house inlet temperature. Interaction is a major concern. Opening either hot air damper decreases the hot air pressure. Opening the hot air damper to bag house inlet increases the bag house inlet temperature. Opening the hot air damper to scrubber duct inlet alters the distribution of hot air so as to decrease the bag house inlet temperature.

Watch Now

Video: Commissioning the Alternate Control Configuration

The loops proposed in the previous video complete the alternate control configuration. A previous video also examined tuning the feedback trim controller for the hot air temperature. This video will tune the other three loops. The first issue is the order for tuning the loops.

Video: Analysis of Performance of Alternate Control Configuration

The critical variables are the scrubber duct inlet temperature and the bag house inlet temperature. Both must remain above the dew point at all times. This video examines how these two loops affect each other.

Video: Providing Capability for Manual Control

In process applications the operator must be able to assume control of any final control element and specify its opening. This video examines the mechanisms for providing this capability.

Video: Using Output Tracking for Bumpless Transfer from Manual to Automatic

Tracking comes in two versions – output tracking and integral tracking. Output tracking provides smooth transitions from manual operations to automatic operations. Integral tracking prevents reset windup. Output tracking is the subject of this video.

Watch Now

Video: Output Tracking for the Hot Air Temperature Controller

This video examines output tracking for the hot air temperature controller. The hot air temperature controller outputs to a summer whose output is the fresh air damper opening.

Video: Output Tracking for the Hot Air Dampers

Previous videos examined output tracking for the scrubber duct inlet temperature controller and the hot air temperature controller. This video examines output tracking for the hot air pressure controller and the bag house inlet temperature controller.

Watch Now

Video: Integral Tracking for the Hot Air Temperature Controller

For a PID controller to perform as expected, changes in the controller output must lead to changes in the opening of one or more final control elements, which must affect the measured variable for the PID controller. Driving a final control element to either limit disrupts this sequence. This requires integral tracking, not output tracking. If the final control element has been driven fully open, control actions to increase the opening cannot be implemented, but control actions to decrease the opening can be. The opposite is true if the final control element is driven fully closed.

Watch Now

Video: Integral Tracking for the Hot Air Dampers

Should a hot air damper be driven either fully open or fully closed, integral tracking must be activated in either the hot air pressure controller or the bag house inlet temperature controller. The issues are similar to those for output tracking presented in a previous video.
