INTEGRATED CHEMICALS COMPLEX CONTAINING OLEFINS

摘要

The present invention provides an integrated chemical complex comprising one or more unit operations selected from the group consisting of a steam cracker comprising a C2 splitter, a linear alpha olefin plant and a solution or slurry polyethylene plant the improvement comprising integrating into the complex a reactor for the trimerization or tetramerization of ethylene in the presence of a catalyst system comprising: (iv) a source of chromium; (v) a defined P-N-P ligand; and (vi) an activator and a distillation column to separate one or more of ethylene, 1-hexene, 1-octene which olefins containing less than 1.5 weight % of internal olefins. The integration provides savings in terms of capital costs, operating costs or both.
