⛷️ Just completed a fascinating deep-dive into CPChem's BF₃-catalyzed LAO-to-PAO oligomerization technology - a process that would otherwise remain completely opaque to the industry.

THE INTELLIGENT APPROACH I USED:
🔍 Patent Archaeology: Started with Gulf Oil's 1982 EP0077113A1 patent - the three-component BF₃/alcohol/glycol/ketone system that revolutionized PAO selectivity
📊 Cross-Reference Validation: Connected CPChem's US6410812B1 BF₃ recovery patent with active supplier relationships (Gulbrandsen 2025 recognition)
🧪 Process Logic Reconstruction: Built equipment sequences based on:
◼️ BF₃ handling requirements (PTFE-lined, pressure control)
◼️ Cationic polymerization kinetics (45-55°C, CSTR configuration)
◼️ Mass balance constraints (>95% BF₃ recovery economics)
📐 Engineering Diagram Development: Created Mermaid flowcharts showing:
◼️ Feed preparation (1-decene from integrated NAO)
◼️ Catalyst mixing (n-butanol/ethylene glycol/MEK ratios)
◼️ Reactor cascade (primary/secondary CSTR)
◼️ Recovery systems (flash drums, caustic wash, fractionation)

THE RESULT:
A comprehensive process description with equipment tags, operating conditions, and mass balances that would typically require proprietary access to develop.
