Engineering study to purification of pyrolysis oil using hydrotreatment
Publieke samenvatting / Public summary
Aanleiding
The Dutch government aims for a net climate neutral and at least 80 percent circular handling of raw materials, products and processes in the industry by 2050. By 2025, regulations by law require companies to reuse and recycle 50% of all plastic packaging. Recycling plastic is a critical component of sustainable waste management and plays a significant role in conserving resources, reducing environmental impacts, and promoting economic and social benefits. While there is necessity to promote plastic recycling, recycling of plastics and their associated waste poses challenges. To avoid downcycling, a mixture of waste plastics can be converted into useful products, like pyrolysis oil. The main issue for implementing pyrolysis oil on a large scale in petrochemical plants as chemical building blocks are the impurities. Underlying reason is that purification and homogenization of these oils is needed for the petrochemicals industry to ensure a steady operation of the steam cracker while maintaining high quality of the resulting product. At this moment, purification capacity is not available nor demonstrated on industrial scale and only 1% of pyrolysis can be mixed into the cracker feed
Doelstelling
The objective of this study is to investigate the technological and economic feasibility of purifying pyrolysis oil from waste plastics using hydrotreatment. VPR Energy will furthermore investigate all the necessary prerequisites for initiating the construction project of a hydrotreatment unit at their site. The ultimate goal is thereby to achieve a final positive investment decision and enable application of all proposed environmental measures in a follow-up project.
Korte omschrijving
The work in this project is divided in four different work packages. The first work package is focused on the technical feasibility, while in the second work package the required permits and environmental impact will be studied. For this study VPR Energy intends to make use of several external partners with different specialities. The feasibility of transporting feedstock and its derived products will be tackled in work package 3. The final work package combines all results from the previous work packages to build up the business case of the intended project and estimates the GHG emission avoidance related to the follow-up project.
Resultaat
At the end of the study VPR Energy will have confirmed both the technical and economic feasibility of the chosen technology. The generated information will act as base for the final investment decision to further proceed with the realization of the demonstration plant. As the treated pyrolysis oil will be reused to produce circular plastic products and other chemicals, this will yield a reduced need for crude oil that is currently used to produce plastic products and chemicals contributing to the CO2-emission reduction and circularity of raw materials goals.
