Critical Steps in Process Design
Michel Gigon, Associate, Laporte Consultants September 28, 2006
Agenda
Definitions and General Considerations
Critical Steps in Process Design
Definitions
Product Development : Creation of a new product
Process Development : Development of a production method (recipe)
Process Design : Design of the equipment required for the production of a product, according to a pre-determined process.

Definition of the user requirements• Process
• Production capacity
• Product specification
• Development phase of the product
Conceptual design
Conceptual design
Definition of the user requirements• Process
• Pilot plant : unit operations, lab procedure example
• First commercial plant : lab method, preliminary results from pilot plant
• Subsequent facility : existing process
Conceptual design
Definition of the user requirements
• Production capacity • Requirements (kg/year, units/year)
• Batch size (kg/batch, units/lot)
• Titre (kg/L)
• Production time (days/lot)
• Production schedule (24/7, 8/5)
• Operation (by campaign, by lots)
• Production opening (weeks/year)
• Losses (%)
• Equipment utilisation (%)
Conceptual design
Definition of the user requirements
• Production capacity • Requirements (kg/year, units/year)
• Batch size (kg/batch, units/lot)
• Titre (kg/L)
• Production time (days/lot)
• Set-up, production process, cleaning, sterilisation, testing, product change-over….

• Equipment utilisation (%)
• Pilot plant : 20-50%
• First commercial plant : 70% max
• Mature process : > 80%
Definition of the user requirements• Product specification
• Sterility
• Water quality
• Concentration

Conceptual design
Preliminary design
Facility definition and sizing• Preliminary specifications of the process equipment
• Sizing of utilities
• Sizing of spaces
• Preliminary specifications of the automation system
Preliminary design
Facility definition and sizing• Preliminary specification of the process equipment
• Volume, capacity
• Material
• Functionality
• Process paramaters
• Design and operation range (pressure, temperature, etc…)
Preliminary design
Facility definition and sizing• Sizing of utilities and spaces
Process equipment
Process supportCIP, solution prep…
Process Utilitieswater, effluent treatment…
Spacesproduction, mechanical rooms, warehouse…
Building utilitiesHVAC, Steam, chilled water, power…
Preliminary design
Facility definition and sizing• Preliminary specification of the automation system
• Manual vs automated operation
• Transfer panel vs manifold…
• Level of automation
• Local controller, unit operation control, batching, archiving
• General architecture
Preliminary design
Facility definition and sizing Risks
• Inadequate process equipment
• Insufficient space and utilities
• Inadequate control and automation
• => Production capacity cannot be met
• => Difficulties of operation

Construction and Fabrication
Start-up and testing• Verification of the quality of fabrication
• Verification of all design hypothesis
• Control of process parameters
• Process sequences are achievable
• Equipment drainable, cleanable and sterilisable
Construction and Fabrication
Construction follow-up Documentation follow-up Start-up and testing (FAT, SAT) Risks
• Inadequate installation
• Cleaning and contamination issues
• Ergonomic and operational issues
• Inadequate documentation
• Validation issues
• Maintenance issues
Validation
Adequate documentation facilitates protocol preparation and execution
Review of validation criterion can avoid unnecessary deviation
Participation in protocol execution facilitates and accelerates protocol execution
