This critical fractionation system achieves high thermodynamic efficiency, simple and reliable operation, and an optimized configuration. This system reduces energy consumption significantly compared with the previous high-pressure, indirectly refrigerated system.
The combination of front-end acetylene hydrogenation and open-loop ethylene/ethane fractionation
will allow the production of the highest-purity ethylene and the lowest energy consumption. The
hydrogen and carbon monoxide concentrations in the product ethylene are almost unmeasurable (
