Liquefied Ethane for Petrochemical Feedstock
Liquefied ethane (C2H6) is a gaseous hydrocarbon chilled to below -89°C for storage and transport as a liquid. It falls under HTS 2711.19.00.10 as 'other' liquefied petroleum gases, specifically ethane, distinct from methane, propane, or butanes. Primarily used as a feedstock for ethylene production via steam cracking.
Liquefied Ethane Refrigerant Grade
High-purity liquefied ethane used as a refrigerant in industrial cryogenic systems, meeting specifications for low boiling point (-88.5°C). Classified under HTS 2711.19.00.10 as liquefied ethane, separate from common LPGs like propane. Essential for ultra-low temperature cooling in labs and food processing.
Liquefied Ethane for Ethylene Cracker Plants
Industrial-grade liquefied ethane shipped in bulk for use in steam crackers to produce ethylene monomer for polyethylene manufacturing. HTS 2711.19.00.10 specifically covers liquefied ethane as 'other' petroleum gases. Sourced from natural gas liquids (NGL) fractionation.
Cryogenic Liquefied Ethane NGL Fraction
Ethane fraction extracted from natural gas liquids (NGLs) via cryogenic processing, liquefied for pipeline or marine transport. Falls precisely under HTS 2711.19.00.10 as liquefied ethane, excluding methane. Used primarily in plastics industry supply chains.
