Results & Conclusion
The main objective in this project is to use natural raw materials (lignin) that will support us to produce a natural desired product (thermoplastic) and as well as both materials are bio based, they are biodegraded materials. The Different processes for thermoplastic manufacture from lignin was illustrated and described in details and the proper and convenient process had been chased based on economic and environmental aspects. In addition, material and energy balance has been performed and applied. Moreover, simulating selected process, designing process equipment, making the necessary cost estimations and income from thermoplastic manufacturing facility and making HAZOP and environmental assessment of the selected process has been achieved. Finally, safety environmental considerations of this process and project management were studied.
Lignin as a main raw material dissolves in DMAC to prepare the first solution while the second solution prepared by dissolving Sebacoyl Chloride in DMAc also. First solution and second solution are mixed together and fed to semi-batch CSTR reactor. In addition, Triethylamine is added also to the reactor as a catalyst. The reaction occurs in the reactor where the heat of reaction is exothermic. Then the reactor product which is contains the lignin based thermoplastic filtered to remove TEA-HCl as a solid side product before washed by water to allow precipitation of the polymer which will be dried at the end of the process.
