In the dynamic field of polymer and intermediate petrochemical production, maintaining efficiency and product quality is paramount. From preventing unplanned downtime to ensuring the safety of chemical storage, optimizing production processes can lead to significant improvements in both performance and cost-efficiency. Here are five crucial strategies to optimize production:
1. Predict Maintenance of pH Sensors to Eliminate Unplanned Downtime
Utilizing intelligent sensor technology, such as METTLER TOLEDO’s Intelligent Sensor Management (ISM®), enables predictive maintenance of pH sensors. This technology has proven indispensable at Mitsubishi Chemical Corporation, where it has transformed pH measurement operations. The ability to monitor sensor conditions continuously and predict maintenance needs ensures reliable and stable operations, significantly reducing unplanned downtime and associated costs.
2. Prevent Product Discoloration by Stopping Unwanted Polymer Oxidation
In the production of polymers like polyethylene terephthalate (PET), preventing oxidation is crucial to maintain product quality. In-line amperometric sensors for oxygen measurement provide real-time monitoring, allowing immediate corrective actions to prevent discoloration and ensure the production of high-quality, color-consistent polymers.
3. Simplify Maintenance and Control to Reduce Process Interruption
Implementing condition-based maintenance using ISM technology simplifies sensor maintenance and control. By predicting the need for calibration and cleaning, plants can avoid unnecessary process interruptions. This proactive approach has been highly effective at Mitsubishi Chemical Corporation, where it has led to a major replacement program of pH measurement systems with ISM solutions.
4. Ensure Safe Storage of Hazardous Chemicals to Avoid Runaway Polymerization Reactions
Proper monitoring and control of storage conditions for hazardous chemicals are essential to prevent runaway polymerization reactions. Advanced sensor technologies enable continuous monitoring of key parameters, ensuring safe and stable storage conditions, thus protecting both the facility and the environment.
5. Optimize Exhaust Monitoring to Avert Problems at Scrubbers
Efficient exhaust monitoring is critical to managing emissions and ensuring compliance with environmental regulations. Advanced monitoring systems provide accurate, real-time data on exhaust composition, enabling immediate corrective actions to prevent issues at scrubbers and other emission control systems.
Case Studies in Optimized Production
Switching to Condition-Based Maintenance: Mitsubishi Chemical Corporation
The Mizushima plant of Mitsubishi Chemical Corporation faced challenges with the reliability of pH sensors in harsh process conditions. The implementation of METTLER TOLEDO’s ISM technology allowed for predictive maintenance, significantly improving the stability and efficiency of pH measurements. This success has led to plans for a major replacement program across the plant.
Avoiding Discolored Plastic with In-line Oxygen Measurement
PET production requires stringent control of oxygen levels to prevent unwanted color changes. The use of in-line oxygen sensors, such as the InPro® 6950 i G, ensures continuous monitoring and quick detection of even small amounts of oxygen, maintaining the desired product quality and appearance.
Seamless Process Monitoring at Nalco
For Nalco Deutschland GmbH, a leader in water treatment chemicals, maintaining high product quality and regulatory compliance is vital. The adoption of ISM technology has enhanced process analytical systems, providing the necessary assurance and ease of maintenance.
Exhaust Gas Treatment
At Nalco’s Biebesheim plant, exhaust gases generated during the production of water additives are treated in multiple stages, including a sulfuric acid scrubber, a sodium hydroxide neutralization scrubber, and an active carbon filter. METTLER TOLEDO’s InPro 4260 i pH electrodes with M700 transmitters are integral to this system, allowing for easy sensor withdrawal and calibration without process shutdown. The ISM technology ensures pre-calibrated sensors are always available, significantly reducing process interruption.
Monitoring Raw Materials
Nalco also uses ISM sensors to monitor the pH of biological acrylamide, preventing autopolymerization during storage. This ensures safe and efficient production, as well-calibrated pH electrodes can be quickly replaced to maintain continuous monitoring.
Future Plans for ISM at Nalco
Nalco plans to expand the use of ISM sensors to other measurement systems, including oxygen level determination during inertization, further enhancing their process monitoring capabilities.
Safe Storage of Acrylonitrile and Other Hazardous Chemicals
Acrylonitrile must be stored under strict conditions to prevent hazardous polymerization. METTLER TOLEDO’s pH measurement and sensor cleaning systems provide real-time data and prevent technician exposure to this dangerous compound. The InPro® 3250 i pH sensor and EasyClean™ 400 system offer continuous monitoring and automated maintenance, ensuring safe storage conditions.
Analytical Measurements in Gas Scrubbers
Wet gas scrubbers are essential for preventing environmental pollution. METTLER TOLEDO’s advanced sensors, such as the InPro 7250 inductive sensors and InPro 4800 i pH electrodes, provide reliable measurements and reduce maintenance costs by up to 90%. These robust sensors ensure high efficiency and compliance with environmental regulations.
