Abstract

PT Arsynergy Resources merupakan perusahaan nasional yang bergerak di bidang pengolahan gas bumi dari Lapangan Bukit Tua menjadi produk Liquefied Petroleum Gas (LPG), lean gas, dan kondensat. Salah satu unit vital dalam proses pemurnian gas adalah unit dehidrasi yang memanfaatkan Molecular Sieve Dehydrator untuk menghilangkan kandungan uap air dari gas umpan. Proses regenerasi media adsorben yang jenuh membutuhkan gas regenerasi (regen gas) yang dipanaskan menggunakan Shell and Tube Heat Exchanger (E-408) dengan fluida pemanas Therminol 66. Penelitian ini bertujuan untuk mengevaluasi kinerja termal Heat Exchanger E-408 berdasarkan data operasional aktual menggunakan metode Kern. Parameter utama yang dievaluasi meliputi laju perpindahan panas (Q), efektivitas termal ε, koefisien perpindahan panas menyeluruh kondisi bersih UC, koefisien perpindahan panas menyeluruh kondisi kotor UD, serta faktor pengotoran (fouling factor / Rd). Hasil evaluasi menunjukkan laju penyerapan panas oleh gas regenerasi pada sisi tube (Qc) sebesar 2.184.373 Btu/jam dan pelepasan panas oleh Therminol 66 pada sisi shell (Qd) sebesar 2.196.993 Btu/jam. Efektivitas termal alat mencapai 97%. Dari hasil perhitungan koefisien perpindahan panas, diperoleh nilai UC sebesar 136,08 Btu/jam·ft²·°F dan UD sebesar 100,91 Btu/jam·ft²·°F, sehingga menghasilkan faktor pengotoran Rd sebesar 0,00256 hr·ft²·°F/Btu. Nilai faktor pengotoran aktual ini masih memenuhi batas toleransi standar perancangan, sehingga Heat Exchanger E-408 disimpulkan beroperasi secara optimal dan efisien tanpa memerlukan tindakan pembersihan (cleaning) dalam waktu dekat.
==================================================================================================================================
PT Arsynergy Resources is a national natural gas processing company converting raw gas from the Bukit Tua Field into Liquefied Petroleum Gas (LPG), lean gas, and condensate. A critical unit in the gas purification process is the dehydration unit, which utilizes a Molecular Sieve Dehydrator to eliminate moisture from the feed gas. The regeneration process of the saturated adsorbent bed requires regeneration gas (regen gas), which is heated using a Shell and Tube Heat Exchanger (E-408) with Therminol 66 as the heating fluid. This study aims to evaluate the thermal performance of Heat Exchanger E-408 based on actual operational data using Kern's method. The primary parameters evaluated include the heat transfer rate (Q), thermal effectiveness (ε), clean overall heat transfer coefficient (UC), dirty overall heat transfer coefficient (UD), and fouling factor (Rd). The evaluation results indicate that the heat absorption rate by the regeneration gas on the tube side (QC) is 2,184,373 Btu/hr, while the heat release rate by Therminol 66 on the shell side (Qh) is 2,196,993 Btu/hr. The thermal effectiveness of the equipment reaches 97%. Based on the heat transfer coefficient calculations, UC and UD are obtained as 136.08 Btu/hr·ft²·°F and 100.91 Btu/hr·ft²·°F, respectively, resulting in a fouling factor Rd of 0.00256 hr·ft²·°F/Btu. This actual fouling factor remains within the allowable design tolerance limits; thus, Heat Exchanger E-408 is concluded to operate optimally and efficiently without requiring immediate cleaning maintenance
