Engineering Excellence for Complex Process Industries

Optimizing Chemical Operations

Dr. Saidas (Sai) Ranade offers over 15 years of deep technical expertise in chemical process consulting. His career spans the full lifecycle of industrial projects—from the drawing board of an EPC firm to the control room of an Operating Company, and finally to the board room as Director of Technical Services.

This multifaceted background allows Dr. Ranade to see beyond the PFDs (Process Flow Diagrams). He understands the pressures of operations, the constraints of engineering design, and the capabilities of modern simulation software.

Success Stories

Gas Leak Simulation

The Challenge: A client needed to accurately predict the dynamics of accidental gas releases from pressurized vessels.

The Solution: Developed a rigorous unsteady-state model based on isentropic expansion principles, allowing the client to design better safety systems.

Operational Debottlenecking

Outcome: Led a technical services team that identified a critical constraint in a chemical plant's reactor loop, implementing a modification that increased throughput by 10%.
