What is crude C4?

Crude C4 is a coproduct of ethylene production. The exact quality and quantity produced are highly variable. They depend on cracker feedstock selection and quality, operating severity, furnace technology, among other things. As a result, crude C4 is typically sold on a component basis in the US.

What is the quality difference between crude C4 and ethane based C4?

There is a significant quality difference in the crude C4 streams as well. Ethane based crude C4 is nearly 70% butadiene while naphtha based crude C4 is over 50% raffinate. Crude C4 from butane cracking has 35% or so normal butane as all of the uncracked butane ends up in the crude C4.
