Yanshan Petrochemical Company after having expanded its 300 kt/a steam cracking unit to 450kt/k in 1994 is still experiencing such problems as low feedstock flexibility, high energy consumption and smaller scale as compared to other ethylene units constructed in the same time. In order to fully improve technical capability of steam crackers, reduce energy consumption, improve feedstock flexibility and increase production capacity, a lot of technical revamp cases on steam cracking were studied and compared with attention focused on the feasibility, safety, operability of the related revamp cases, as well as the advanced nature and economical features of the cases studied. As regards the pyrolysis-quench-compression system, the steam crackers will be retrofitted on the site with the pyrolysis gasoline fractionation tower, quench water tower, pyrolysis gas compressor and steam turbine replaced by new ones, respectively. The separation system will adopt a low-pressure methane removal technology with the demathanizer tower replaced, coupled with the C3 catalytic rectification/hydrogenation technology, while the high-pressure depentanizer will be replaced with the addition of a propylene rectification tower. The fractionation flow sheet and equipment will be adjusted with the addition of a propylene compressor and compressor for binary mixture of methane-ethylene cooling agents. This revamp has expanded the ethylene capacity to the target of 660 kt/a with the actual capacity reaching 710 kt/a. This revamp project has remarkably reduced the energy consumption, which is capable of using naphtha, light diesel fuel, heavy diesel fuel and the hydrocracked tail oil as the steam cracking feedstock. This project is the first to apply refrigeration by means of a mixed ccx)ling agent and has succeeded in using C3 catalytic rectification/ hydrogenation technology, which has given an impetus to the progress of steam cracking industry in the world.
