Crude oil, heat exchanger, water contentAbstract
PPSDM Migas memiliki kilang minyak berkapasitas 600 m3 per hari dimana crude oil yang diproduksi akan menghasilkan berbagai macam produk, seperti pertasol CA, pertasol CB, pertasol CC, naphta, solar, dan residu. Salah satu unit operasi yang digunakan dalam proses produksi ini adalah heat exchanger yang bertujuan untuk meminimalisasi penggunaan bahan bakar pada proses pemanasan furnace. Dari lima heat exchanger yang ada di lapangan, terdapat kerusakan di salah satu heat exchanger, yakni HE-05. Oleh karena itu, dilakukan analisis mengenai penyebab kerusakan HE-05 dengan metode penelitian berupa studi lapangan dan studi pustaka, seperti pengambilan data kondisi operasi di Distributed Control System (DCS) dan secara langsung di lapangan menggunakan Piping & Instrumentation Diagram (P&ID) sehingga dapat menghitung overall mechanical energy balance.
Berdasarkan hasil analisis, dapat disimpulkan bahwa kandungan water content di dalam crude oil melebihi ambang batas (< 0,7%) sebesar 5,5%. Water content yang tinggi akan memengaruhi fraksi uap dari crude oil yang berakibat pada kenaikan tekanan operasi. Kemudian, safety valve yang berada di stabilizer tidak berfungsi sehingga gasket dari HE-5 tidak mampu menahan tekanan yang tinggi pada kejadian tersebut. Selain itu, pembacaan sensor tekanan dan suhu yang tidak akurat menyebabkan telatnya operator dalam menanggulangi kejadian tersebut.
