Decoking cycles result in increased maintenance costs, increased downtime, increased fuel consumption, and higher emission.
Undesirable run lengths and costly decoking cycles would be observed when using at least a portion of pyoil in the feed to a cracking furnace. When feeding pyoil at normal operating conditions for either liquid or gas cracking, the coking rates of the furnace can be increased without taking precautions or process modifications. Commercial facilities involved in the production of non-biodegradable products could benefit greatly from using recycle content feedstocks because the positive environmental impact of using recycle content feeds could offset the negative environmental impact of making non-biodegradable products. To maximize recycling efficiency, it would be desirable for large-scale production facilities to be able to process feedstocks having recycle content originating from a variety of waste materials. In many cases, expensive physical sorting of waste materials into relatively pure, single-composition waste volumes is required. Further, different types of waste materials often require different types of recycling processes. While some waste materials are relatively easy and inexpensive to recycle, other waste materials require significant and expensive processing in order to be reused. However, recycling waste materials can be challenging from an economic standpoint.
Thus, from an environmental standpoint, it is desirable to recycle as much waste materials as possible. Waste materials, especially non-biodegradable waste materials, can negatively impact the environment when disposed of in landfills after a single use. 62/852,367 filed on May 24, 2019, the disclosure of which is herein incorporated by reference in the entirety.
