PROCESS YIELD IMPROVEMENTS

Process yield improvements optimize existing facilities to achieve more favorable product specifications within the existing design and economic constraints. Plant managers, process engineers, and plant operators may know that their processes are not optimized. The processes may be good and may safely and consistently provide good quality product, but new conditions could warrant review and modification of the facility.

Conditions influencing the decision to improve an existing facility include:

• Federal emissions regulations
• Quality improvement requirements
• Feedstock changes
• Economic stresses
• Feedstock, catalyst, or rare metal shortages

Parsons provides process yield improvement services to:

• Perform independent audit services.
• Evaluate the effectiveness of ongoing programs.
• Troubleshoot specific processing problems that may be occurring.
• Analyze a variety of processing problems, ranging from below-standard yield to unsatisfactory finished product appearance.
• Bring processing procedures into compliance with U.S. Food and Drug Administration regulations, good manufacturing process directives, European Union directives, and client specifications.
• Assist processors to increase the effectiveness and efficiency of their production processes.
• Identify viable options-criteria include yield; selectivity; reasonable cycle time; fit into existing equipment; additional unit operations: safety, health, and environmental considerations; probability of success; and additional costs.
• Perform process simulations and analyze option viability.
• Provide resource-efficient experimental programs that are designed and successfully executed to achieve high yield with desirable cycle times.
• Assist with improving the yield of finished products from input raw material.
• Provide startup assistance, around-the-clock supervision, and evaluations to meet performance guarantees.
• Train plant management, staff, and line personnel so that they understand the concepts behind corrective adjustments.
• Confirm that trained staff monitor the appropriate process control points, recognize when the process is operating within specified control limits, and initiate corrective action when it is not.
