Abstract

ABSTRAK PT. TPPI Tuban merupakan perusahaan petrokimia dan refinery penghasil produk petroleum dan aromatics Benzene, Toluene, Xylene (BTX) yang berlokasi di Tuban, Jawa Timur. Potensi bahaya kebakaran dan ledakan dapat terjadi pada tangki, salah satunya diakibatkan oleh sambaran petir. Loncatan arus sambaran petir terjadi karena sistem penyaluran arus ke pembumian kurang maksimal. Penelitian ini dilakukan dengan metode evaluasi berdasarkan peraturan dan kondisi kenyataan proteksi penyalur petir dilapangan, dan dengan simulasi dampak ledakan pada tangki menggunakan software ALOHA. Peraturan SNI 03-7015-2004, katalog ERITECH 1000 dan API 545 digunakan sebagai standar evaluasi penelitian ini. Hasil analisis wilayah dampak ledakan didapatkan radius ledakan zona merah 1,87 km, zona orange 2,65 km dan zona kuning 4,04 km dari tangki reformate. Hasil evaluasi pada SNI 03-7015-2004 menyatakan tingkat protekesi level IV dimana mengharuskan dilakukan pemasangan sistem proteksi petir eksternal disetiap tangki. Didapatkan secara optimal penambahan penghantar penyalur dan air terminal pada desain SPP eksternal sebanyak satu air terminal pada setiap tangki, dengan ketinggian 3 meter dari permukaan atap tangki, berdasarkan katalog produk ERITECH 1000. Hasil evaluasi berdasarkan API 545 pada tangki reformate, menyatakan bahwa tidak adanya sistem proteksi petir pada tangki dengan pemasangan bonding system dan insulation. Oleh karena itu, pemasangan bonding system sebanyak 51 buah shunt dan lima buah bypass conductor, serta pemasangan insulation pada komponen konduktif selain shunt dan bypass condcutor pada tangki reformate perlu dilakukan. Kata Kuci : Bonding System and Insulation, Lightning Protection System, Metode Sudut Proteksi, Simulasi Threat Zone, Storage Tank ABSTRACT PT. TPPI Tuban is a petrochemical company and refinery which producing petroleum and aromatics products among others Benzene, Toluene, Xylene (BTX), where located in Tuban, East Java. Potential fire and explosion hazards can occur in the tank, one of the causes is by a lightning strike. Steppimg electrical current occurs because the current distribution system to the grounding less than the maximum. This research is conducted by evaluation method based on regulation and reality condition of lightning strain protection field, and by simulating the impact of explosion on tank using ALOHA software. Regulation SNI 03-7015-2004, catalog ERITECH 1000 and API 545 are used as evaluation standards for this research. The result of the explosion area analysis was obtained by red zone explosion radius 1.87 km, orange zone 2.65 km and 4.04 km of yellow zone from the reformate tank. The result of evaluation on SNI 03-7015-2004 states the level IV, which requires the installation of external lightning protection system in each tank. It was found optimally for the addition of down conductor and air terminal to the external SPP design of one air terminal and down conductor for each tank, with height of three meters from the tank roof surface, based on the ERITECH 1000 product catalog. The results of the API 545 based evaluation of the reformate tanks stated that the absence of a system Lightning protection in the tank with the installation of bonding system and insulation. Therefore, the installation of 51 shunt bonding systems and five bypass conductor, and insulation installation on conductive components other than shunt and bypass condcutor in reformate tanks need to be done. Keywords : Bonding System and Insulation, Lightning Protection System, Method of Angle Protection, Storage Tank, Threat Zone Simulation
