Abstract
Energi Mega Persada Bentu Ltd mendistribusikan natural gas kepada PLN Pekan Baru secara natural flow. Tekanan natural gas dari sumur di lapangan Segat semakin lama akan mengalami penurunan. Sesuai dengan hasil simulasi reservoir yang telah dilakukan EMP Bentu Ltd, jika tetap menggunakan natural flow natrural gas tidak bisa didistribusikan hingga akhir periode PJBG, untuk itu perlu dilakukan sizing kompresor dimana kompresor yang akan ditempatkan di Seng Gas Plant. Kompresor digunakan untuk meningkatkan tekanan gas dari sumur agar tekanan dari wellhead dapat diatur lebih rendah sehingga gas dapat didistribusikan hingga akhir periode PJBG. Sizing kompresor reciprocating dimulai dengan menghitung sifat-sifat kimia dari natural gas yang didapatkan dari komposisi kimia gas. Perhitungan kecepatan spesifik dilakukan untuk mengetahui apakah tipe kompresor yang dipilih sudah sesuai dengan kebutuhan. Sizing dilanjutkan dengan menentukan jumlah stage, diameter silinder dan daya yang dibutuhkan di setiap stage dan. Langkah selanjutnya adalah menghitung rod load untuk mengetahui beban maksimum yang terjadi pada komponen reciprocating. Pada sizing ini didapatkan jumlah stage dan daya kompresor yang sesuai dengan kebutuhan di Seng Gas Plant, yaitu 100 psig pada sisi suction, 450 psig pada sisi discharge dengan flow rate 15 MMSCFD. Dalam sizing kompresor reciprocating didapat rod load pada masing-masing stage

Energi Mega Persada Bentu Ltd. know distributes natural gas to PLN Pekan Baru naturally flow. Over time the pressure of natural gas from wells at Segat field will decrease. According to reservoir simulation EMP Bentu Ltd. results, if natural gas distribution still using natrural flow, natural gas can’t be distributed until the end of the PJBG (contract agreement between buyer and gas seller). So that need gas compressor which will be placed in Seng Gas Plant. This compressor is used to increase the pressure of the gas from the well so that the pressure of the wellhead can be set lower and then the gas can be distributed until the end of the PJBG.The sizing of reciprocating compressor starts from calculating the chemical properties of natural gas obtained from the chemical composition of the gas. specific speed calculation is performed to determine whether the type of selected compressor is right according to the needs. The design followed by counting the number of stage, power needed by each stage and cylinder bore at each stage. Next is calculating the rod load to determine the maximum load that occurs in reciprocating components. The result In this final assignment is obtained the number of stage and power needed by compressor according Seng Gas Plant requirement, which is 100 psig on the suction side, 450 psig at the discharge side with a flow rate of 15 MMSCFD. Rod load at each stage reciprocating compressor are obtained
