The Grispin Process™ Part 4:

Refining the Product

As it holds true in the petrochemical and plastics world, no product is truly pure straight out of the reactor. The Grispin Process employs a series of separations methods in order to split the various product streams, isolating each stream in preparation for final product development.

The majority of these separation methods are ones that are common to individuals in the petrochemical or refining facility industry would be intimately familiar. However, so as to best streamline the efficiency of the overall system, some of the separation processes employ unit operations and operating principles that have been developed by our CTO, Charles Grispin. These bespoke unit operations utilize cutting edge technologies, some of which are yet to be implemented on a wide scale across the process industry. Much akin to the main process reactor, these custom unit operations have been developed over decades of research and process tuning.

The Grispin Process™ Part 3:

The Grispin Process can be summarized in this very step: Over four decades of genius, hard work, trial & error, and exhaustive pyrolysis process development have led to the vast wealth of knowledge and experience is how our CTO, Charles Grispin, commands our technology platform.

Needless to say, there are a number of components involved in this part of the process that may colloquially be referred to as “the secret sauce.” Each parameter, valve type, pipe size, and so forth are specifically selected and tuned to achieve unparalleled results in percentage of conversion, range of raw material and product quality.

In short: the feedstock stream enters the reactor, and through pyrolysis, is converted to a number of products, depending on the tuning parameters of the reactor. These products can include, but are not limited to: polymer plastics feedstocks, ultra-low sulfur diesel, naphtha feedstocks, hydrocarbon gases equivalent to natural gas, among others.

Part 2
PRF: The Plastics Repurposing Facility

The second step in The Grispin Process is the Plastics Repurposing Facility, or PRF. Here, the imported bales of mixed plastic waste are de-baled for sortation. As you may imagine, even with the some of the highest attention to detail from the feedstock suppliers, when you are dealing with plastic waste that may have been headed to landfills, there remains the risk of contaminates. In order to eliminate off-spec raw materials, the de-baled mix plastic waste goes through an extensive sortation process to remove any remaining incompatible materials.

Depending upon the raw material, this sortation process in the PRF consists of six to eight different steps, each of which are highly specialized and designed to separate the different types of impurities encountered with mixed plastic waste. This separated material, not supported by The Grispin Process, can either be sold to alternative post-consumer recycling entities or disposed of appropriately.

Once the feedstock stream has been optimized, it is then ready to be fed into the Grispin Process reactors.

The Grispin Process™ – Part 1

Importation: the receipt of the plastic waste

Every day, all over the country, approx. 72,000 tons of plastic waste are sent to various landfills to be buried or incinerated without any consideration about how better use this valuable resource.

The first step in The Grispin Process™ is to work with the landfills, waste collection entities and independent producers to reclaim this previously unusable waste as feedstock to be repurposed into feedstocks for new monomers or ULS fuels for transportation use!

Before the feedstock material even is loaded on the truck to be delivered, hours of planning and work have gone into the selection of the materials. Much like any other process, quality raw materials can make all the difference.

Hand in dirty hand, we work to sort and manage this plastic waste. This is the first step in our Grave-to-Cradle approach for plastic waste.

A 2017 report prepared for the American Chemistry Council examined emissions from a family of technologies known as pyrolysis has determined that emissions from these processes are likely to be very low – much lower than the emissions profiles from other industries, such as food processing, auto manufacturing, and even lower than institutional buildings, such as hospitals and universities.

As ACC explains, pyrolysis is a versatile process that can convert non-recycled plastics into liquid fuels, lubricants, waxes, or even polymer feedstocks.

These findings follow Argonne National Laboratory’s determination that the production of ultra-low diesel derived from post-use, non-recycled plastics results in lower greenhouse gas emissions and water and energy use compared to ultra-low sulfur diesel derived from conventional petroleum. ANL’s findings were presented in the peer-reviewed journal Fuel (Volume 203, 1 September 2017, Pages 11-22). #chemicalrecycling, #renewableenergy
