So this heat transfer fluid product, with anti-cok

So this heat transfer fluid product, with anti-coking properties, is really expensive: $6500 - 7000 per ton.

I sure hope they do not need to use a lot of it.  Or, if they do, that they can reclaim most of it as part of the process.

Why am I getting very nervous about the cost of processing plastic back into oil?
