Abstract

Heat exchanger adalah salah satu instrumen yang vital yang berguna untuk memindahkan panas tanpa diikuti oleh perpindahan partikel fluida. Performansi dari heat exchanger sendiri dapat dilihat melalui fouling resistance, overall heat transfer coefficient, pressure drop, dan head duty. Untuk meningkatkan overall heat transfer coefficient dan menurunkan pressure drop dilakukan penambahan teknologi berupa helical baffle pada sisi shell dan internal fins pada sisi tube. Untuk menemukan geometri paling optimal dari kedua teknologi tersebut dilakukan proses optimisasi menggunakan dua metode optimisasi, yaitu Genetic Algorithm dan Killer Whale Algorithm dengan variabel optimisasi adalah baffle spacing, helix angle, fin thickness, dan fin number. Setelah diterapkan teknologi yang paling optimal didapatkan nilai U= 844 W/m²K yang mengalami peningkatan sebesar 52% dibanding desain awal, dengan nilai ΔPS= 8.95 kPa dan ΔPT= 15.2 kPa. Peningkatan U sekaligus meningkatkan head duty, yang berpengaruh pada nilai saving hasil optimisasi meningkat sebesar 28% menjadi 2.447.573 USD per tahun.

Heat exchanger is the one of vital instrument that utilized for transfer heat without transferring the fluid particle used. Heat exchanger performance itself can be determined by its fouling resistance, overall heat transfer coefficient, pressure drop, and head duty. For increasing overall heat transfer coefficient and decreasing pressure drop, this research has added helical baffle on shell side and internal fins on tube side. To obtain the most optimum geometry of both technology, it has been done optimization process using two optimization method, Genetic Algorithm and Killer Whale Algorithm, with baffle spacing, helix angle, fin thickness, dan fin number being the decision variable. After the most optimum geometry of technology obtained and applied, value of U= 844 W/m²K, which increasing for 52% compared to former design, with value of ΔPS= 8.95 kPa and ΔPT= 15.2 kPa. Increased of U also enhance the head duty, which make the value of saving from optimization process increased by 28% to the value of 2.447.573 USD per year.
