Abstract
Heat exchanger adalah alat yang digunakan untuk menukar energi termal (entalpi) antara dua atau lebih cairan, antara permukaan padat dan cairan, atau antara partikulat padat dan cair, pada suhu yang berbeda dan dalam kontak termal (Shah, 1960). Heat exchanger yang terus dioperasikan akan terbentuknya fouling. Fouling ini akan menimbulkan kerugian yang cukup besar seperti meningkatkannya capital cost. Berdasarkan permasalahan fouling pada heat exchanger, maka diperlukannya untuk meminimalkannya fouling resistance tersebut dengan menggunakan metode optimisasi genetic algorithm. Fouling resistance yang didapatkan dibandingkan dengan 4 jenis crude oil. Jenis crude oil yang meliputi dulang 1983, tapis 1983, miri light 1983 dan bintulu 2001 pada data assay di Aspen HYSYS V10. Lalu dilakukan pemodelan based line untuk fouling resistance pada heat exchanger E-1102 dan E-1106 dengan menggunakan Polley model. Didapatkan hasil based line fouling resistance untuk E-1102 sebesar 1.89E-04 dan E-1106 sebesar 3.68E-04. Setelah itu dilakukan optimisasi dengan metode evolutionary dan genetic algorithm (GA). Setelah dilakukan optimisasi dengan memanipulasi laju aliran masa masing-masing crude oil untuk produk kerosene. Setelah dioptimisasi telah didapatkan hasil nilai fouling resistance untuk E-1102 sebesar 1.78.E-04 dan 1.73E-04 sedangkan E-1106 sebesar 3.59.E-04E-05 dan 3.40E-05.

A heat exchanger is an equipment used to exchange thermal energy (enthalpy) between two or more liquids, between a solid and a liquid surface, or between solid and liquid particulates, at different temperatures and in thermal contact (Shah, 1960). Heat exchanger that continues to be operated will form fouling. This fouling will cause considerable losses such as increasing capital costs. Based on the problem of fouling in the heat exchanger, it is necessary to minimize the fouling resistance by using a genetic algorithm optimization method. The fouling resistance obtained is compared with 4 types of crude oil. Types of crude oil which include dulang 1983, tapis 1983, miri light 1983 and bintulu 2001 in the assay data in Aspen HYSYS V10. Then the modeling for fouling resistance on the heat exchanger E-1102 and E-1106 was carried out using the Polley model. The results of the fouling resistance modeling for E-1102 is 1.89E-04 and E-1106 is 3.68E-04. After that, optimization was carried out using evolutionary and genetic algorithm (GA) method. After optimization by manipulating the mass flow rate of each crude oil for kerosene products. After optimization, the fouling resistance value for E-1102 is 1.78E-05 and 1.73E-05 while E-1106 is 3.59E-05 and 3.40E-05.
