Plastic Recycle TechnologiesDorf Ketal Technology toimprove crude profitabilityResearch shows that just 12 percent of plastic waste is currently reused or recycled across the globe. This is because of the fact that the great majority of used plastics goes to incineration, landfills, or dumps. As a result, these materials are lost forever as a resource, despite plastic's potential for reuse and recycling. Plastic production requires substantial capital investment and increased carbon footprint. Reusing plastics not only reduces these investment needs, but can also contribute to reducing total industrial carbon emissions. ChallengeAt Dorf Ketal, we are relentlessly striving to develop chemicals and chemical processes to maximise recycling of plastics. We have developed a process, where certain grades of plastics can be directly recycled by blending/mixing it with vacuum residue stream in crude oil refining. Generally, this vacuum residue is further processed in a visbreaker or delayed coker for getting more valuable products.SolutionBy using Dorf Ketal technology, in this process, capital expenditure would be minimised. As per lab studies, conducted on more than 100 different grades of plastics, it has been proved that this process helps in increasing yield of more valuable products as compared to coke & can hence improve additional profitability for end users. Furthermore, it would help reduce the carbon footprint.ImpactWe were posed a challenge at a refinery situated in the ASEAN region, to operate their crude unit efficiently and expand the crude window. The problem resulted in lot of recycling of crude posing operational and scheduling challenges.ChallengeWe recommended a developed proprietary model known as %u201cOil Capability Model%u201d. It is a very robust chemical solution that combats undesired deposition in heat exchangers and also implemented.SolutionThe Oil Compatibility Model helped to determine and predict issues with a given crude blend. This helped to proactively suggest chemical treatment rates. The chemical additive reduced the loss of heat energy and greatly enhanced operational reliability and profitability by inhibiting the deposition.Impact30
