- Automating power management software
- Improving operational efficiency of energy management
Allurént offers over 30 years of engineering expertise in a wide variety of services for the optimization and automation of your paper machine control system (DCS):
Paper Machine Services
Our paper machine optimization solutions includes cross direction and machine direction tuning, beam modeling calculations, multiple frequency actuator control tuning, wave model setup and other advanced paper manufacturing control schemes. We specialize in the following Honeywell Measurex control system services:
- Headbox alignment for precise control after a major shutdown or machine modification is always required for accurate mapping of actuators to control zones in the process control system. This services is always included in our optimization packages.
- Paper machine optimization
- CD control optimization
- CD cabinet replacement
- Pulp Related Services
- Batch and continuous digester, process trouble shooting and control tuning
- Waste Fiber Plant, process trouble shooting and control tuning
- De-Inking plant, process trouble shooting and control tuning
- Cross Direction Weight Optimization
The following pulp and paper manufacturing items are determined to provide the best possible performance of a CD weight control:
- Headbox to scanner alignment
- Mini-slice profile mapping to CD actuator zone verification. (Profile transformation)
- Machine direction profile filtering
- Weight bump response modeling
- Optimal machine direction tuning numbers determined from actual bump tests
- Determination of cross coupling and spatial filtering requirements to provide optimal controls without actuator picketing
- Wave modeling on a Honeywell Measurex MxOpen control system
- Cross Direction Moisture Optimization
The following items are determined to provide the best possible performance of a CD moisture control when manufacturing pulp and paper products:
- CD moisture actuator to scanner alignment
- Mini-slice profile mapping to CD actuator zone verification. (Profile transformation)
- Machine direction profile filtering
- Moisture bump response modeling
- Optimal machine direction tuning numbers determined from actual bump tests
- Determination of proper spatial filtering requirements to provide control performance
- For more than one CD moisture control the proper frequency components have to be determined for each control. Typically a steam box operates on a low frequency profile and a spray bar operates on a high frequency profile to deliver the highest performance possible without cross control coupling problems. These frequency components are determined by modeling the bump responses of each CD control actuator.
- Machine Direction Control Optimization
- Machine Direction Moisture Optimization
The following items are determined to provide the best possible pulp and paper manufacturing performance of a MD control:
- Calibration and limit verification of all PID and supervisory loops involved
- Process response modeling and determination of tuning numbers
- Determination of decoupling constants for weight and moisture controls
- Verification of proper execution of control algorithms
- All process models and tuning calculations documented
- CD Control Using a PLC with I/P Transducers
- Your choice of PLC vendor (Allen Bradley, GE, etc.)
- Custom built to your mill specifications
- Rack mounted I/P transducers with stainless steel air manifold
- Internal integrated air regulator and filtering system
- 15 years of CD control installation experience behind each CD bay configuration
- Designed with the end user in mind. Lower cost long term maintainability
- Direct replacement and compatibility with existing CD bays
