Abstract

Soap is a product that commonly used as a cleanser and can be made through a saponification reaction between fat and base with glycerol as byproduct. The reaction kinetics of soap production is the study of how fast the soap production and it is an important part in reactor modeling and the optimization of operating conditions. On the other hand, glycerol is a byproduct of soap production which can be applied into various derivative products so that the glycerol purification process from soap production process is important to do. This review discusses the reaction kinetics of soap production and glycerol purification from alkaline soap waste. In general, the kinetics curve of the soap-making reaction consists of three stages, namely the induction period, the constant velocity period and the decreasing velocity period where the base concentration in the soaping reaction was related to the reaction rate. The lower base concentration used, the soap production reaction will slower. The soap production reaction had low activation energy and identified as second order reaction. In the process of purifying glycerol from alkaline soap waste, three main stages were generally used, namely neutralization, alcohol separation and glycerol purification.

Abstract

Refined Bleached Deodorized Palm Oil (RBDPO) is a product of the crude palm oil (CPO) refining process. RBDPO is one of Indonesia's strategic commodities for low price cooking oil production. The cooking oil processing uses a heat transfer device such as heat exchanger. Heat exchanger sealtube 881X is a tool that used in the heat recovery unit at PT. Tunas Baru Lampung, Tbk refinery plant. Heat exchanger sealtube 881X used to cool refined bleached deodorized palm oil (RBDPO) to 95 – 105oC from the deodorization process by utilizing cooling water. In this research, the efficiency and fouling factor of the heat exchanger sealtube 881X were calculated at PT. Tunas Baru Lampung, Tbk refinery plant. Based on the results, it can be seen that the actual efficiency of Heat exchanger sealtube 881X was between 71-87%. Changes in the value of fouling factor affect the thermal efficiency of the heat exchanger sealtube 881X which from the calculation results, the highest fouling factor value was 0.0017.

Abstract

Karbon dioksida (CO2) merupakan gas rumah kaca yang banyak dihasilkan di industri dan berpengaruh terhadap peningkatan pemanasan global. Pemanfaatan CO2 untuk dikonversi menjadi senyawa bernilai tinggi merupakan salah satu cara untuk meningkatkan nilai tambah dari gas CO2. Salah satu produk yang dapat dihasilkan dari gas CO2 adalah sodium karbonat (Na2CO3) yang diproduksi dari reaksi antara karbon dioksida (CO2) dan sodium hidroksida (NaOH). Sodium karbonat merupakan senyawa kimia yang banyak digunakan dalam industri sebagai bahan kimia penunjang. Sodium karbonat dapat terbentuk dari proses penyerapan gas CO2 menggunakan larutan NaOH. Pada penelitian ini diteliti simulasi produksi natrium karbonat dengan variasi suhu reaksi dan laju alir reaktan yang dilanjutkan dengan perancangan reaktor produksi natrium karbonat bertipe reaktor gelembung. Reaktor gelembung dipilih karena merupakan reaktor sederhana tanpa adanya komponen moving parts. Pada penelitian ini variabel berubah yang digunakan adalah simulasi variasi suhu dan laju alir dimana persamaan volume reaktor yang digunakan adalah tipe reaktor alir tangki berpengaduk dengan tipe pengaduk six-blade turbine dan sparger bertipe wheel. Hasil penelitian menunjukkan bahwa suhu 20oC dengan laju alir 20 ton/jam CO2 dan 20 ton/jam NaOH menghasilkan Na2CO3 terbanyak sebesar 8 ton/jam dengan volume reaktor sebesar 25,11 liter. Suhu reaktor yang tinggi akan menghasilkan ukuran reaktor yang semakin kecil. Sedangkan besarnya laju alir CO2 yang digunakan sebagai reaktan pembatas akan menghasilkan Na2CO3 yang terbentuk semakin meningkat. Perhitungan perancangan reaktor gelembung menghasilkan ukuran diameter dalam reaktor sebesar 26,76 cm dan tinggi reaktor sebesar 68,03 cm.
