Abstract
Dalam usaha meningkatkan profitabilitas dan mengurangi emisi karbon dioksida, banyak proses di industri telah menerapkan upaya untuk meminimalkan konsumsi energi dengan memaksimalkan rekoveri panas melalui heat exchanger network (HEN). Akan tetapi, fouling pada heat exchanger adalah deposit yang tidak diinginkan yang mengurangi realisasi pemanfaatan dari integrasi panas secara maksimum. Setiap fouling mempunyai cara pembersihan yang efektif. Thermal cleaning untuk foulant yang berupa wax (lilin).Cleaning schedule menggunakan fenomena hot melting mempunyai banyak kelebihan yaitu cleaning dilakukan tanpa penambahan peralatan khusus, tidak perlu melepas dan memasang kembali bundle heat exchanger serta tidak memerlukan waktu yang lama, hot melting terdapat pada heat exchanger no.2, 3, 4, dan 8 fenomena hot melting terjadi pada saat heat exchanger mengalami keadaaan power trip. Dari hasil optimisasi menggunakan fenomena hot melting diapatkanl bahwa setiap heat exchanger yang didapati mengalami fenomena hot melting mengalami kenaikan efisiensi untuk heat exchanger no.2 mengalami kenaikan sebesar 44% dengan desain efisiensi 62%, heat exchanger no.3 29% dengan desain efisiensi 59%, heat exchanger no.4 41,8% dengan desain efisiensi 74%, dan heat exchanger no.8 37,8% dengan efisiensi 67 % rata kenaikan efisiensi dari ke empat heat exchanger yang terdapat fenomena hot melting adalah sebesar 38,15 %. Dari hasil optimisasi cleaning scheduling menggunakan hot melting mendapatkan nilai saving energi sebesar $1,69 juta

In an effort to increase profitability and reduce carbon dioxide emissions, many processes in the industry have implemented efforts to minimize energy consumption by maximizing heat recovery through a heat exchanger network (HEN). However, fouling in a heat exchanger is an unwanted deposit which reduces the realization of the maximum utilization of heat integration.Chemical cleaning for foulants which can be dissolved with certain solvents and thermal cleaning for foulants in the form of wax. Therefore fouling in the heat exchanger must be cleaned and fouling can be cleaned by a process known as hot melting. Cleaning schedule using the hot melting phenomenon has many advantages, namely cleaning is carried out without the addition of special equipment, no need to remove and reinstall the bundle heat exchanger and does not require a long time, hot melting is found in the heat exchanger No. 2, 3, 4 and 8 hot melting occurs when the heat exchanger experiences a power trip condition. From the results of the optimization using the hot melting phenomenon, it was found that each heat exchanger found to experience a hot melting phenomenon experienced an increase in efficiency for the heat exchanger No. 2 which increased by 44% with a design efficiency of 62%, no. %, no. 4 heat exchanger 41.8% with design efficiency 74%, and no. 8 heat exchanger 37.8% with efficiency 67%, average increase in efficiency from the four heat exchangers with hot melting phenomenon is 38.15% from cleaning schedule optimization using hot melting obtained energy saving $1,69 billion.
