Debottlenecking of Batch Operations INTELLIGEN, INC. EquipmentResources Types of Bottlenecks Annual Throughput Batch Throughput x Number of Batches per Year =
INTELLIGEN, INC. Equipment Scheduling (Time) Bottlenecks Auxiliary Equipment (e.g., CIP and SIP skids) and resources also can become time bottlenecks. Tank (V-101) = Scheduling (Time) Bottleneck
Equipment Capacity Utilization INTELLIGEN, INC. Equipment Capacity Utilization Liquid Volume Max Liquid Volume = Equipment Capacity Utilization Operating Throughput Max Throughput =
Equipment Time Utilization INTELLIGEN, INC. Equipment Uptime Total Time Equipment is Utilized per Batch Effective Plant Batch Time (EPBT) = EPBT
Equipment Throughput Bottlenecks INTELLIGEN, INC. Combined Utilization = Equipment Capacity Utilization x Equipment Uptime

Debottlenecking Strategy INTELLIGEN, INC. Annual Throughput Batch Throughput / Effective Batch Time Increase batch throughput until a size bottleneck is reached. Then, Increase number of cycles of limiting procedure; Rearrange equipment, or; Use new equipment (stagger operation).
Throughput Analysis Example INTELLIGEN, INC. Production of Therapeutic Monoclonal Antibodies

INTELLIGEN, INC. Equipment Utilization Chart (Base Case) V-101 = Scheduling (Time) Bottleneck EPBT = 11 days Batch Throughput = 2.3 kg Batches per Year = 29 Annual Throughput = 67 kg
INTELLIGEN, INC. Capacity, Time, and Combined Utilization Chart (Base Case) 65% = Capacity Utilization of Bottleneck Equipment
