Abstract

Pyrolysis, which converts plastic waste into energy through a heating process without oxygen, has been proven to reduce waste volume by up to 90% while becoming an alternative fuel with high economic value. The optimal pyrolysis temperature of 380°C produces the most significant amount of pyrolysis oil, with a potential thermal efficiency of up to 80%. The main challenges in optimizing pyrolysis include energy efficiency, operational costs, and production scale. This study aims to improve the efficiency of the pyrolysis process by enhancing the reactor, condenser tube, and control system. With this approach, it is hoped that a more cost-effective, environmentally friendly plastic waste management solution can be created that supports the concept of a circular economy in Cirebon City. The result is that with a plastic waste composition of 30% PP and 70% LDPE and the addition of a kaolin catalyst to the pyrolysis reactor, it can produce oil equivalent to gasoline with an octane rating of 88. This optimization can reduce the use of fossil fuels, create new jobs, and significantly contribute to environmental sustainability.

Abstract

Jenis penukar kalor sangatlah beragam dan masing masing dirancang untuk memenuhi kebutuhan yang spesifik. Namun demikian jenis shell & tube sejauh ini merupakan jenis yang paling banyak dipergunakan berkat konstruksinya relative sederhana dan memiliki keandalan karena dapat dioperasikan dengan beberapa jenis fluida kerja. Efek pendinginan yang dihasilkan dalam sistem perpindahan panas tergantung dari efektivitas kinerja kondensor. Sementara, kinerja kondensor semakin lama akan menurun seiring dengan terjadinya fouling factor. Pada penelitian ini dilakukan analisa perhitungan jumlah tube dan diameter tube pada kondensor sebagai Alat Penukar Kalor (APK). Dari hasil analisa perhitungan adalah jumlah tube 663 buah, diameter tube 40 mm, panjang tube 2,5 m.
