The difference between ethylene and coal tar
Thread Content
Can ethylene tar and medium-temperature coal tar be processed simultaneously? Ethylene tar, coal tar, and residue oil can be processed simultaneously; they cannot
There are technologies for co-processing coal and residue oil; as for these three types of tar you mentioned, it’s still necessary to consider their physical and chemical properties and compare them
It depends on what the end product is; mixing different types of oils can affect the quality of the product, and it’s very difficult to do so
Ethylene tar cannot be processed together with coal tar, because one of the products of coal tar distillation is 95% naphthalene; some components in ethylene tar have boiling points similar to those of naphthalene, and mixing them would result in a naphthalene purity that does not meet the required level of 95%
