Inherent Safer Design and Safe Scale Up
Removing the hazard while the decision is still cheap to make
Inherent safety is decided early and defended late. This course covers the four strategies of minimise, substitute, moderate and simplify, the project stages where each still has leverage, and the scale up decisions where laboratory chemistry meets plant scale heat transfer.
This course sits alongside our Inherent Safer Design consulting work, so what is taught is what we do.
Who should attend
Course content
Every module is taught with worked examples and exercises drawn from real plant, and adapted to your own process where the course runs in house.
The four strategies
- Minimise, reducing the inventory that can be released
- Substitute, replacing a hazardous material or route
- Moderate, using less severe conditions or dilution
- Simplify, removing the complexity that causes error
Where the leverage is
- Route selection at research stage as the highest leverage decision
- Concept and front end design and what can still be changed
- Why detailed design offers protection rather than inherent safety
- Conflicts between inherent safety and cost, yield or schedule
Measuring and comparing options
- Inherent safety indices and their limitations
- Comparing routes on hazard rather than on cost alone
- Documenting a decision so that a later reviewer understands the trade
Safe scale up
- Surface area to volume ratio and the collapse of heat removal capacity
- Mixing, mass transfer and residence time changes with scale
- Reaction calorimetry data needed before scale up
- Process intensification, continuous processing and flow chemistry as inherent safety measures
What you receive
- An inherent safety review checklist by project stage
- A route comparison worksheet
- A scale up data requirement list
- Assessment result and attendance record
What changes afterwards
- Hazards get removed at the stage where removal is still affordable
- Route selection considers hazard alongside yield and cost
- Scale up proceeds with the thermal data it requires
- Continuous and intensified options are evaluated rather than dismissed
