Neraca Panas, Lime Mud, Rotary Lime Kiln, Regenerasi, Heat LossAbstrak
Pada rotay lime kiln terjadi proses regenerasi lime mud yang merupakan produk samping dari proses recausticizing. Proses regenerasi terjadi pada suhu 800-1150oC didalam rotary lime kiln. Kalsium oksida digunakan untuk menghasilan white liquor yang digunakan untuk memasak chip pada digester, dengan mereaksikan kalsium oksida dengan green liquor pada unit slaker. Kapasitas umpan pada rotary lime kiln di PT. Toba Pulp Lestari, Tbk adalah sebesar 15.500 Kg/jam. Perhitungan neraca panas pada penelitian ini bertujuan untuk menghitung panas yang dibutuhkan dan menghitung heat loss selama proses regenerasi. Berdasarkan hasil perhitungan yang telah dilakukan didapatkan pada tanggal 27 Oktober, 10 November, dan 17 November 2023 panas yang dibutuhkan sebesar 2.637.664,1596 kJ, 2.406.529,3947 kJ, 2.979.403,7560 kJ dan heat loss sebesar 1.569.158,8721 kJ, 1.712.299,3215 kJ, 1.872.099,4966kJ.
