Butene via Ethylene Dimerization

By Chemical Engineering |

Olefin dimerization is a reaction where two molecules of a monomer combine to form a dimer. It can be utilized to produce normal butenes from ethylene, which can be provided by a steam cracker. Dimerization of ethylene is generally applied when butene is required in another part of a petrochemical complex. For instance, the dimerization unit may be integrated with a metathesis unit, to produce polymer-grade propylene, a commodity chemical with a high added value. In this integration, n-butene from dimerization is reacted over a metathesis catalyst with ethylene to form two molecules of propylene, as shown in the block flow diagram, in Figure 1.  FIGURE 1. Integration between dimerization and metathesis FIGURE 2. n-butenes production process similar to Lummus Ethylene Dimerization Technology The process A dimerization process for butenes production, similar to CB&I Lummus (The Woodlands, Tex.; www.cbi.com) Ethylene Dimerization Technology, is analyzed and depicted in the flowsheet (Figure 2). The following is a brief description of the dimerization processing scheme: Catalyst preparation and treatment section. Catalyst and co-catalyst are properly unloaded, stored and pumped into the catalyst preparation section. Ethylene…
