There are distinct differences leading to potential performance benefits for  NCTI’s wash oil products versus the Aromatic 100, 150, and 200 in the market. Most importantly,NCTI’s AS-220, AS-160 and AS-110 are perfectly compatible (can be blended into the same tank) with petroleum-based wash oils such as Aromatic 100, 150, & 200. Our workhorse as a wash oil in ethylene/propylene crackers is the AS-110 and the AS-160 is specified by UOP Honeywell for PDH facilities.

Aromatic 100, 150, & 200 type products are petroleum based, in other words, they originate from crude oils. As such, they have basic characteristics that our products do not have. Our products originate from chemical manufacturing processes, in particular, catalytic reactions between basic commodity type chemicals. Since these two products originate from different sources, their overall characteristics have some differences as well.

Aromatic 100, 150, & 200 type products are made up of substituted naphthalenes and biphenyls. This petroleum stream contains some amounts of naphthalene as well. The “heavies” in this stream are substituted biphenyls. The biphenyl molecule that has methyl and ethyl groups attached to one or both of the benzene rings.

Our AS-220, AS-160, and AS-110 wash oil products do not have these same molecules. As such, we would not expect to see the same types of coking that are potentially possible with the biphenyl and substituted containing molecules.
