Reception Oil Tank (ROT) is a unit at a clarification station that has a function as a temporary storage tank for filtered crude oil from the vibro-separator unit and also to retain heat. In this ROT, the heat provided comes from direct injection of hot steam and steam coils with temperatures ranging from 90-95 0C. This research was conducted with the aim of determining the flow rate of materials into and out of ROT using the principle of mass balance and determining the levels of each component in the oil in ROT before further processing. Based on the results of the mass balance calculation, it was obtained that the flow rate of crude oil entering ROT was 10794.2 kg/hour. The composition content of the materials entering ROT in 10 mL includes 37.6% oil, 26.6% water and 35.8% non-oil solid while the composition levels of materials leaving ROT to CST include 41.6% oil, 27% water, and non-oil solids 31.4%. The oil content has increased during the process that occurs in the ROT at the clarification station.

“…The mass balance is a proper calculation of all the materials that enter, accumulate, and come out within a specific time [25]. Material equilibrium (mass balance) can be formulated in the conservative system [26] in the palm kernel pressing process, as shown in Figure 1. F 1 is the mass rate of the kernel that enters the first press (tons/day), F 2 is the CPKO mass rate that comes out of the first press (tons/day), F 3 is the mass rate of cake that comes out of the first press and will enter the second press (tons/day), F 4 is the mass rate of CPKO that comes out of second press (tons/day), and F 5 is the mass rate of Palm Kernel Meal (PKM) that comes out of second press (tons/day).…”

<p class="E-JOURNALAbstractBodyEnglish">PT XYZ Belawan has a kernel crushing plant unit that produces Crude Palm Kernel Oil (CPKO) with 700 tons/day capacity. Palm kernel processing is carried out in two pressing stages. The first stage or first press produces oil and cake, while the second stage or second press produces oil and meal. The meal still contains 7-8% of the oil content. This study is aimed to determine the amount of CPKO yield, oil content, and oil losses in a meal during the pressing palm kernel process. The method used was the calculation of the mass balance in each process flow. The mass balance calculation is carried out after collecting the secondary data from the factory, including the analysis of water content, solids, FFA, and oil content. Based on the calculation results, CPKO yield was 48.10% of the average kernel mass rate of 714.7155 tons and met the plant standard of at least 44%. Furthermore, the average yield of oil content from the meal was 7.45% and oil losses were 3.86%.</p>

“…Alat ini menerapkan prinsip perpindahan kalor yang umumnya memiliki bentuk frame yang diberi plat sebagai sekat-sekat [4]- [6]. Berbeda halnya dengan steam yang digunakan pada pengolahan CPO di pabrik kelapa sawit yang diproduksi melalui ketel uap (boiler) dengan batu bara sebagai sumber energi [7]- [9]. PHE memiliki beberapa keunggulan dibandingkan penukar panas tabung lainnya seperti biaya yang rendah, penghematan energi dan fleksibilitasnya dalam mengubah area permukaan perpindahan panas.…”

Daun teh yang merupakan bagian penting dari tanaman teh dapat diolah menjadi minuman teh dalam kemasan yang menjadi produk utama PT. XYZ Tanjung Morawa. Kunci keberhasilan pada produksi minuman teh dalam kemasan adalah penyeduhan daun teh yang menggunakan air panas bersuhu 90-95 ºC dimana air dipanaskan menggunakan steam di unit extract tank dengan bantuan alat plate heat exchanger. Penentuan banyaknya steam dalam proses penyeduhan daun teh diperlukan untuk menghitung nilai panas yang dilepas ke lingkungan atau yang diserap oleh daun teh selama proses penyeduhan daun teh di unit extract tank sebagai data tambahan dan informasi pendukung pabrik. Dalam penelitian ini dilakukan analisa kebutuhan steam pada proses penyeduhan daun teh dengan mengumpulkan data sekunder yang langsung diperoleh dari pabrik dan menghitung jumlah panas dari komponen bahan dengan stoikiometri dan konsep panas untuk menentukan kebutuhan steam. Berdasarkan hasil perhitungan diperoleh bahwa dengan rata-rata suhu air panas dengan laju air sebesar 5500 L/jam maka jumlah panas yang dibutuhkan sebanyak 1.454.700,012 Kkal/jam dan steam yang dibutuhkan sebanyak 3840,6481 Kg/jam dalam proses penyeduhan daun teh sebanyak 40-50 Kg
