Prarancangan Pabrik Biogas dari Limbah Sisa Makanan, Limbah Pabrik Tahu, dan Limbah Darah Rumah Potong Hewan dengan Proses Fermentasi Anaerobik Dua Tahap Kapasistas Bahan Baku 25.000 TonTahun

Abstract

Preliminary Plant Design: Preliminary Design of a Biogas Plant Utilizing Food Waste, Slaughterhouse Blood Waste, and Tofu Factory Waste with a Two Stage Anaerobic Fermentation Process and a Raw Material Capacity of 25,000 Tons/Year This plant is designed to operate 330 days a year. The core process of this preliminary plant design, which uses a two-stage anaerobic fermentation process, consists of four stages: Pretreatment, Biogas Formation, Purification, and Compression. The end product is methane with a purity of <98% at a pressure of 200 atm, resulting in bio-CNG with a production capacity of 3,441.64 tons/year and a bio-CNG volume of 7.57 m³/kg. The planned plant location is at the Maspion Industrial Estate, Gresik Regency, East Java, covering a total area of 15,246 m². Water requirements for this plant are supplied from the Kalimireng River, totaling 35,453.52 kg/hour. The organizational structure of the planned company will be a Limited Liability Company (PT) with a line-and-staff organizational structure, employing a total of 125 people. Based on economic analysis, it is concluded that establishing the Biogas Plant from Food Waste, Slaughterhouse Blood Waste, and Tofu Factory Waste with a Two-Stage Anaerobic Fermentation Process and a Raw Material Capacity of 25,000 Tons/Year is feasible.
