Molecules To Market Program

🎙️ Molecules to Market is a program by Portfolio Planning PLUS (ppPLUS), bringing together technology, economics, and real facility-level data to give industry professionals a grounded, technical view of the global energy and petrochemical landscape — beyond the headlines.

In this multi-part video series, Sanjay Gupta — former CEO Projects for the Dangote Refinery and Petrochemical Project, and former Chairman & Managing Director of Engineers India Limited (EIL) — takes on a new challenge: designing a model grassroots refinery-petrochemical complex for India, starting from first principles.

The DREAM Refinery — Part 1: The Foundation 

Part 1 lays the strategic foundation. Sanjay explains why India continues to add refining capacity, why new installations are shifting from the west coast to the east coast, and why tomorrow’s “refineries” will actually be integrated mega petrochemical complexes in disguise. He walks through the design basis and objective function: a crude throughput of around 20 million tonnes — the sweet spot for a single crude column — feeding a world-scale steam cracker of 1.7–2 million tonnes of ethylene, an aromatics complex of 1.2–1.5 million tonnes, and a product slate that still delivers LPG and diesel while capping gasoline.

The DREAM Refinery — Part 2: Identity and General Engineering

Picking up right where the power cut left us in Part 1! In this episode, Sanjay Gupta gives our model refinery project an identity: welcome to the "Dream Refinery", to be located on India's east coast, in the Tamil Nadu / Chennai region. Sanjay explains the strategic logic behind going east: energy security, Bay of Bengal offshore exploration, and the export opportunity toward Southeast Asia, Australia, Japan and Korea.

Then the episode gets deep into the engineering: the full secondary and tertiary processing scheme designed to maximize petrochemicals. From the vacuum column split to VGO hydrotreating, the high-severity petro FCC targeting 20%+ propylene, and a multi-feed olefin complex recovering ethylene even from FCC off-gases — Sanjay walks through a configuration where gasoline becomes almost an incidental product. Bottom-of-the-barrel is handled by a delayed coker and slurry hydrocracker combination, with the C₄ mix potentially converted via KBR's K-COT technology.

💡 Highlights in this episode:
⚓ Offshore infrastructure: crude SPMs 20–30 km offshore for VLCCs, product SPMs and jetties
⚗️ Why a petro FCC + VGO hydrotreater + olefin complex trio forms the heart of the secondary processing
🧬 Cracker design decisions: P/E ratio of 0.42–0.50, recovering 100 KTA of ethylene from off-gases
♻️ Sulphuric acid instead of elemental sulphur — a byproduct with positive IRR
☢️ SMR nuclear power plants as a future steam and power source for the complex
💰 Why fossil-fuel power generation at ₹10–12/kWh destroys project IRR vs. grid power at ₹4 — and the Indian capex advantage: ±10% cost estimates that never failed
