  • Optimizing Energy And Asset Costs To Improve Profitability

    Reducing energy and asset costs is fundamental to maximizing the profitability of chemical plants. Harnessing the right data at the right time is the key to generating the efficiencies that improve management in those areas.

  • A Cost-Effective Solution To Exploiting Siloed Data

    Today’s chemical plants collect an extensive array of data ranging from engineering design to asset maintenance, laboratory information, and real-time process operation.  The data collection systems have been deployed over time as necessary and vary widely in age and even in manufacturing origin.  Modern sources of data now include the IoT devices — many connecting straight to the cloud — that might not connect through traditional control systems. Without much thought given to how those systems might function in a collective effort, they now generate a mountain of disparate information.

  • Improving The Pathway To Regulatory Compliance

    Chemical companies are subject to a myriad of federal, state, and local regulations through adherence to air, water, and hazardous waste permits. Remaining compliant, and being able to prove it, is increasingly a challenge.

  • Newer Tools Leverage Optimization To Boost Safety

    With thousands of people killed following a gas leak at a pesticide plant in India, the Bhopal tragedy of 1984 is widely regarded as the world’s worst industrial disaster. More than three decades later, with all the advancements in safety technology, hazardous situations such as Bhopal should be a distant memory.

  • Sustainable Improvements Through Real-Time Insight

    A mandate for overall cost-cutting at chemical companies once triggered a tedious process where plant staff would cram into meeting rooms to pore over spreadsheets, generate potential improvement lists, and attempt to rank the best ideas. While the exercise proved to be somewhat intuitive based on collective experience, much of it missed the mark.

  • Staying Ahead Of Environmental Mandates

    Increasingly strict environmental regulations at the federal, state, and local levels — such as the Greenhouse Gas Reporting Program, flaring efficiency rules, and the Toxic Substances Control Act — are putting more pressure than ever on the chemical industry. As a result, the inability to maintain tight controls and provide documentation that proves compliance can lead to costly fines and possibly even put a halt to operations.

  • Using Advanced Technology To Attack Operational Costs

    Managing and continuously improving operational costs is critical to staying competitive in the chemical/petrochemical industry. The challenge is that primary input costs are under persistent upward pressure while plant managers are locked in a constant battle against unscheduled downtime and underperforming assets.

  • Using The PI System To Drive Dynamic Data Visualization

    Covestro’s story is a common one in the manufacturing world. The company had a wealth of data streaming in from equipment and processes: data that could theoretically be harnessed and acted upon. But its data was difficult to access, stored in local silos, and cut off from sharing and analysis by the lack of enterprise-wide data standards. The fix for Covestro: Making full use of its PI System. 

  • Air Liquide Leverages The PI System™ To Realize A Tenfold Return From Increased Energy

    Founded in 1902, Air Liquide is one of the world’s largest suppliers of industrial gases, including oxygen, hydrogen and nitrogen. Spread across 80 countries, they serve approximately three million customers across multiple industries, including medical, oil and gas, chemical and electronics manufacturers.

  • Proactive Chemical Batch Process Monitoring With Golden Batch Technology

    In its West Chester, Pennsylvania plant, Sartomer, a subsidiary of global chemical company Arkema, manufactures hundreds of acrylic and methacrylic monomers to meet thousands of different customer specifications for paints, inks, coatings, flooring, electronics, and fiber optics.

  • How Michelin Used The OSIsoft PI System To Optimize Elastomer Production

    At its plant in Bassens, France, Michelin manufactures the high-tech synthetic elastomers for its tires. In the past, Michelin’s engineers struggled to track equipment in real time, which is critical for reducing off-spec production and resource waste.

  • Saving Costs, Saving The Planet: Covestro Wins With Energy Management And Sustainability

    Challenges rarely come from just one direction. Like many businesses Covestro, a worldwide leader in polymer production, has been beset by industry, regional, infrastructure, and operational challenges.
