Abstract

Unit Kilang PPSDM Migas Cepu adalah kilang tertua di Indonesia, dan merupakan unit pengolahan minyak bumi yang bekerja sama dengan PT. Pertamina (Persero). Unit Kilang memanfaatkan pompa Distribusi Pertasol untuk mendistribusikan fluida berupa pertasol dari tanki T.133 menuju ke mobil tangki untuk dipasarkan.. Permasahan yang terjadi pada pompa tersebut adalah kerusakan pada mechanical seal. Untuk mengatasi masalah tersebut perlu adanya tindakan investigasi lebih lanjut.
Pada proyek akhir ini didapatkannya hasil perhitungan evaluasi instalasi dan pemilihan pompa yang sesuai untuk pompa Distribusi Pertasol. Untuk perhitungan head, NPSHA, kapasitas, daya pompa dilakukan secara analitis dan numerik menggunakan software pipe flow expert v7.30 serta dilakukan analisa kerusakan yang terjadi pada pompa distribusi pertasol.
Pada perhitungan evaluasi pada instalasi ini didapatkan kapasitas untuk pompa Distribusi Pertasol dengan kapasitas 20 m3/hr dengan head effektif 8,735 m serta didapatkan daya motor sebesar 1,1 kW. Sehingga dari hasil perhitungan-perhitungan tersebut dapat dipilih pompa sentrifugal model NT 40-160 Merk Allweiler. Pada mechanical seal sering diketahui terjadinya getaran yang tinggi dan suara bising pada pompa. Hal ini disebabkan oleh O-ring yang mengalami keretakan, dan keausan pada beberapa part mechanical seal karena umur pakai komponen sudah melebihi batas yang ditentukan. Dengan melakukan kegiatan pemeliharaan secara terjadwal (preventive) pada komponen-komponen mechanical seal, hal itu dapat meningkatkan keandalan dan memperpanjang umur komponen mechanical seal.

PPSDM Oil and Gas Refinery Unit Cepu is the oldest refinery in Indonesia, and is a petroleum processing unit in collaboration with PT. Pertamina. The Refinery unit utilizes the Pertasol Distribution pump to distribute fluid (pertasol) from the T.133 tank to the tank car to be marketed. The problem of the pump is damage to mechanical seal. To overcome this problem, further investigations is needed.
In this final project, the author got the result of instalation evaluation calculation and selection of a suitable pump for the instalation of the distribution pertasol pump. Head, NPSHA, capacity, power, and pump selection calculation are analytical calculated by the author and numerically calculated by Pipe Flow Expert V7.30.
According to the re-evaluation, the author got the capacity for instalation’s of distribution pertasol pump with capacity = 20 m3/hour, Head Effective = 8,735 m, and motor power = 1,1 kW. Therefore the results, of these calculations can be selected single stage centrifugal pump of Allweiler pump type NT 40-160. In mechanical seal, it is often known that high vibrations and noises occur in the pump. This causes damage to the O-ring, damage to stationary and rotary faces and vibrational deflection. The damage was caused by the O-ring being cracked, and the wear and tear that occurred on all mechanical seal parts becauses the service life of the mechanical seal component had exceeded the specified limit, by carrying out scheduled maintenance activities (preventive) on mechanical seal components. It can increase reliability and extend the life of mechanical seal components.
