C4 Raffinate-2

C4 Raffinate-2 is available in standard industrial grades, with compositions optimized depending on the separation process and end-use requirements. It mainly consists of butenes (1-butene and 2-butene) with lower levels of isobutane, n-butane, and trace hydrocarbons, while most butadiene and isobutylene have been removed. This composition makes Raffinate-2 an ideal feedstock for butene-1 production, alkylation units, polymerization, and chemical synthesis. It is extensively used in the production of polyethylene and polypropylene comonomers, fuel blending components, and specialty chemicals. In refinery and petrochemical complexes, C4 Raffinate-2 is also utilized for hydrogenation, oxidation, and further separation processes. Key technical properties include controlled vapor pressure, consistent hydrocarbon distribution, and stable performance under pressurized handling systems.
