The C₃ stream/MAPD selective hydrogenation technology represents a critical and ubiquitous process in modern petrochemical complexes that merits inclusion in the ppPLUS database. This technology is essential for achieving polymer-grade propylene specifications by removing trace methylacetylene and propadiene (MAPD) contaminants that poison downstream polymerization catalysts.

Key justifications for database inclusion:

πŸ”΅ Universal Application: Virtually every steam cracker and propylene production facility globally requires MAPD removal technology, making this one of the most widely deployed petrochemical processes.
πŸ”΅ Economic Impact: Enables high-value propylene monetization and polypropylene production, representing billions of dollars in annual global capacity.
πŸ”΅ Technical Standardization: The liquid-phase trickle-bed reactor configuration has become the industry standard, with well-established design parameters and performance benchmarks.
πŸ”΅ Commercial Maturity: Multiple technology providers (Axens, Shell, Clariant, BASF, Sinopec) offer competing solutions with extensive reference lists.
πŸ”΅ Process Integration: Critical enabler for integrated olefins-to-polymers value chains and renewable/recycled feedstock processing.

MAPD stands for Methylacetylene-Propadiene. It refers to a mixture of two C₃ unsaturated hydrocarbons: methylacetylene (also called propyne, CH₃C≡CH) and propadiene (also called allene, Hβ‚‚C=C=CHβ‚‚). These compounds are structural isomers (same molecular formula, C₃Hβ‚„) and often coexist in equilibrium, especially in industrial contexts.
