Methodology for the synthesis of environmentally compliant chemical process system, case study: the production of biodiesel from vegetable oils
Abstract
Key Words : Reaction Path Synthesis, Renewable-based Processes, Environmentally Compliant, Chemical Process Design
Abstrak
Di antara proses-proses dasar dalam suatu sistem proses kimia,proses reaksi kimia merupakan tahap utama yang paling penting dan menjadi penentu di dalam perancangan proses kimia. Dengan demikian, perancangan sistem proses kimia yang 'memenuhi persyaratan lingkungan' tergantung bagaimana proses reaksi kimia disintesakan dan pertimbangan lingkungan diintegrasikan ke dalam perancangan sistem yang minimal dalam pembentukan limbah, efisien dalam penggunaan bahan baku, dan mengutamakan penggunaan sumber daya yang terbarukan. Suatu upaya telah dilakukan untuk memformulasikan sebuah metodologi di mana penseleksian awal dapat dibuat untuk memunculkan satu kelompok rute-rute reaksi. Berdasarkan rute-rute reaksi ini, optimisasi dilakukan untuk memaksimalkan potensi ekonomi dari sistem proses kimia yang dibentuk berdasarkan rute-rute reaksi yang dipilih pada penseleksian awal dengan menggunakan pemenuhan persyaratan lingkungan sebagai batasan-batasan yang digunakan dalam pelaksanaan optimisasi. Rute reaksi yang optimal ini akan berperan di dalam pembentukan berbagai macam pola pengalokasian komponen bahan ('species allocation'). Pola pengalokasian komponen bahan yang terbaik, dipilih berdasarkan sekumpulan parameter yang terdiri ataspertimbangan-pertimbangan teknis, ekonomis, dan lingkungan. Program 'Hysis' digunakan pada penelitian ini untuk mengevaluasi parameter parameter tersebut.
Kata Kunci : Sintesa Rute Reaksi, Proses-proses Terbarukan, Memenuhi Persyaratan Lingkungan, Desain Proses Kimia
