Dumping plastic waste into landfills can lead to severe health and environmental problems. Plastic waste can be treated by the pyrolysis process to produce fuel. A techno-economic and feasibility assessment was performed for plastic-waste pyrolysis followed by hydrodeoxygenation to upgrade the fuel using the software Aspen Plus. A simulation was conducted using Aspen Plus to estimate the plant’s mass and energy balance; it is assumed that 1,000 dry metric tons of plastic waste is processed per day. Plastic waste contains 40% polystyrene (PS), 20% polyethylene (PE), 20% polypropylene (PP), and 20% polyethylene terephthalate (PET). The process is simulated in five steps: pretreatment, pyrolysis, hydrogen production, and hydrodeoxygenation of oil and energy generation. The mass and the energy yields of this process are 36% and 42%, respectively. The capital investment of the plant and the production cost were calculated based on the Aspen Plus model. Based on the economic estimation, the capital investment of this process is $118 million and the production cost is $27 million. For the 20-year project, the minimum selling price (MSP) of the fuel was calculated to be $0.60/gal. Sensitivity analysis was performed to verify the economic assumptions on the MSP. The MSP is highly sensitive to the feedstock cost, plant capacity, and product yield. As the plant capacity or product yield increases, the MSP decreases significantly.

将塑料垃圾倾倒到垃圾填埋场会导致严重的健康和环境问题。塑料废物可以通过热解过程进行处理以生产燃料。使用软件 Aspen Plus 对塑料废物热解进行了技术经济和可行性评估，然后加氢脱氧以升级燃料。使用 Aspen Plus 进行模拟以估计工厂的质量和能量平衡；假设每天处理 1,000 干公吨塑料废物。塑料垃圾包含 40% 的聚苯乙烯 (PS)、20% 的聚乙烯 (PE)、20% 的聚丙烯 (PP) 和 20% 的聚对苯二甲酸乙二醇酯 (PET)。该过程分为五个步骤进行模拟：预处理、热解、制氢、石油加氢脱氧和能源生产。该过程的质量和能量产率分别为 36% 和 42%。工厂的资本投资和生产成本是根据 Aspen Plus 模型计算的。根据经济估算，该工艺的资本投资为1.18亿美元，生产成本为2700万美元。对于这个为期 20 年的项目，燃料的最低售价 (MSP) 计算为 0.60 美元/加仑。进行了敏感性分析以验证 MSP 的经济假设。MSP 对原料成本、工厂产能和产品产量高度敏感。随着工厂产能或产品产量的增加，MSP 显着降低。该燃料的最低售价 (MSP) 经计算为 0.60 美元/加仑。进行了敏感性分析以验证 MSP 的经济假设。MSP 对原料成本、工厂产能和产品产量高度敏感。随着工厂产能或产品产量的增加，MSP 显着降低。该燃料的最低售价 (MSP) 经计算为 0.60 美元/加仑。进行了敏感性分析以验证 MSP 的经济假设。MSP 对原料成本、工厂产能和产品产量高度敏感。随着工厂产能或产品产量的增加，MSP 显着降低。
