1.3 焦化石脑油烯烃分离技术
Olefin separation technology from coking naphtha
1）Background
延迟焦化石脑油中烯烃含30-40%左右，目前是与焦化柴油混合去加氢装置，加氢石脑油再作为重整原料，造成焦化石脑油中烯
烃的浪费，并且增加加氢成本。
There are about 30-40% olefin in delayed coking naphtha, At present, it is mixed with coking
diesel oil to feed hydrogenation unit, hydrogenated naphtha is used as reforming raw
material, resulting in the waste of olefins in coking naphtha, and increase the hydrogenation
cost.
2）Objective
开发焦化石脑油中链烯烃的分离技术，将链烯烃单独拿出，或者富集至80%以上，作为裂解小分子烯烃的原料。
The separation technology of chain olefin in coking naphtha need be developed, and the
chain olefins are processed separately. Or enriched to more than 80%, and it will be a kind of
raw material for the pyrolysis of small molecule olefins.
