Abstract

Proses produksi AlF3 pada unit persiapan baku memerlukan adanya pemanasan H2SiF6 dengan menggunakan heat exchanger. Namun, suhu output yang diperoleh dari bahan baku H2SiF6 pada pabrik AlF3 memiliki kondisi aktual hanya 74oC dan belum mencapai kebutuhan yaitu 80oC. Oleh karena itu, pada proyek akhir ini perlu dilakukan pendekatan untuk meningkatkan efisiensi kinerja heat exchanger agar dapat diperoleh suhu output H2SiF6 sesuai dengan kebutuhan. Metode yang digunakan yaitu metode sizing problem (rating known) termasuk dalam redesign dengan membandinkan tipe aliran heat exchanger untuk mendapatkan efisiensi yang optimal. Hasil dari efisiensi ini akan dibandingkan dari segi kebutuhan steam, konversi reaksi, jumlah produk, serta analisa ekonomi. Hasil efisiensi dengan metode rating known menunjukkan tipe aliran yang optimal adalah counter flow yang memiliki efisiensi paling tinggi yakni 99.86% dengan suhu output yang sesuai kebutuhan yakni pada 80.2oC. Dengan efisiensi yang tinggi ini dapat menghemat penggunaan steam pada heat exchanger hingga 14% dari kondisi existing. Selain itu, dengan suhu output H2SiF6 pada heat exchanger sebesar 80.2oC dapat meningkatkan konversi produk yang dapat berdampak positif bagi perusahaan dari segi analisa ekonomi karena nilai Total Production Cost (TPC), Pay Out Time (POT), dan Break Even Point (BEP) sesudah efisiensi mengalami penurunan. Berdasarkan hasil proyek akhir ini, maka metode efisiensi heat exchanger secara rating known dapat diaplikasikan secara lebih luas untuk menentukan tipe aliran heat exchanger yang optimal.

The AlF3 production process in the raw material preparation unit requires the heating of H2SiF6 using a heat exchanger. However, the output temperature obtained from H2SiF6 raw materials at the AlF3 plant has an actual condition of only 74oC and has not reached the requirement of 80oC. Therefore, in this final project it is necessary to approach to improve the efficiency of heat exchanger performance to obtain the output temperature of H2SiF6 as needed. The method used is the sizing problem method (rating known) included in the redesign by comparing the heat exchanger flow type to get optimal efficiency. The results of this efficiency will be compared in terms of steam demand, reaction conversion, product quantity, and economic analysis. The efficiency results with the known rating method show that the optimal flow type is counter flow which has the highest efficiency of 99.86% with the required output temperature at 80.2oC. With this high efficiency, it can save the use of steam in the heat exchanger up to 14% of the existing conditions. In addition, the output temperature of H2SiF6 in the heat exchanger of 80.2oC can increase product conversion which can have a positive impact on the company in terms of economic analysis because the value of Total Production Cost (TPC), Pay Out Time (POT), and Break Even Point (BEP) after efficiency has decreased. Based on the results of this final project, the known rating heat exchanger efficiency method can be applied more widely to determine the optimal heat exchanger flow type.
