PREDICT TUBE OVERAL FOULINGIN HEATEXCHANGER 53 EA-1001
Abstract
Alat penukar kalor tipe 53 EA-1001 yang ada pada perusahaan PT. Pupuk Iskandar
Muda beroperasi waktu beberapa lama maka terbentuklah lapisan kotoran atau
fouling, adanya fouling akan mengurangi koefesien perpindahan panas
menyeluruh (U) sampai batas akhir perencanaan alat mencapai harga minimum,
informasi ini diperoleh untuk dapat membuat jadwal rutin berkala pembersihan
dan juga pergantian pipa alat penukar kalor yang tidak layak digunakan lagi
dengan memprediksi penumpukkan fouling maksimum pada alat penukar
kalor.Adanya fouling akan mengurangi koefesien perpindahan panas sampai batas
akhir perencanaan, sehingga dapat dibuat jadwal perawatan rutin. Pengaruh
koefesien perpindahan panas menyeluruh (U) terhadap kecepatan aliran fluida,
mengakibatkan tingginya kecepatan aliran. 8640 jam operasi pada fouling faktor
0,0082 (Rd) menghasilkan volume fouling 0,0066 m
3
perlu perawatan pada usia
APK 27 tahun penyumbatan fouling pada volume 63,585 m
3
. Aliran yang mengalir
adalah laminar dengan nilai 950 Btu.ft
3
/J.lb.s dan tenaga yang hilang 1,46 kali dari
tenaga yang hilang pada keadaan tanpa ada fouling.
Kata kunci : Fouling, alat penukar kalor, koefisien perpindahan panas,aliran, fluida
