ABSTRAK

Orifce merupakan suatu alat yang sangat penting dalam dunia industry terutama pada industri oil n gas dimana penggunaan orifice ini digunakan untuk meciptakan perbedaan tekanan antara sisi upstream dan downstream yang nantinya akan dihasilkan nilai dari pressure suatu fluida yang masuk. Orifice Concentric yang dipakai di PT.Vico Indonesia memiliki kelemahan yaitu rugi tekanan yang sangat besar yang akan berakibat pada peningkatan pressure loss . Pressure loss adalah selisih tekanan yang masuk pada sisi upstream dengan tekanan setelah melewati sisi downstream pada orifice tersebut dan biasanya ditunjukan melalui perbedaan tekanan yang terjadi antara upstream dan downstream. .Slotted orifice merupakan suatu alat yang di berbagai penelitian menunjukkan memiliki perforrma yang lebih dibandingakan dengan standart orifice karena desaign pada plat orifice kurang dipengaruhi oleh sisi upstream pada orifice tersebut dan menghasilkan pressure loss yang relative kecil pressure static bisa kembali dengan lebih cepat ketika dibandingkan dengan orifice standart. Oleh karena itu penelitian ini dilakukan untuk menganalisa koefisien pressure loss yang terjadi antara orifice bertipe slotted dan concentric dengan menggunakan softwere CFD. Dari pengamatan diperoleh nilai koefisien pressure loss untuk orifice concentric Fe-37 nilai koefisien pressure loss sebesar 354 slotted orifice dengan variasi 5 lubang tipe FE-37 nilai koefisien pressure loss sebesar 348 dan slotted orifice dengan variasi 16 lubang tipe FE-37 sebesar 337. Orifice concenctric tipe FE- 1602 nilai koefisien pressure loss sebesar 258 slotted orifice dengan variasi 5 lubang tipe FE-1602 nilai koefisien pressure loss sebesar 254 dan slotted orifice dengan variasi 16 lubang tipe FE-1602 sebesar 243.


ABSTRACT

Orifce is a very important tool in the industry especially in the oil n gas industry where the use of this orifice is used to create a whole difference in pressure between the upstream and downstream value that will be generated from the pressure of a fluid intake. Concentric orifice used in PT.Vico Indonesia has the disadvantage that it has very large pressure losses that would result in an increase in pressure loss. Pressure loss is the difference of incoming pressure on the upstream side to the downstream side of the pressure after passing through the orifice is usually shown through the difference in the pressure between the upstream and downstream. . Slotted orifice is a tool in a variety of studies have shown that it have a performance that is better than the standard orifice because desaign of orifice plate are influenced by the upstream side of the orifice and produces relatively small pressure loss static pressure could return more quickly than standard orifice. Desaign to be used on slottted orifice area must have the same diameter with concentric orifice in order to diperbandingakan where daalm this thesis is used as much as 5 slotted holes and 16 pieces in platenyaTherefore this study was conducted to analyze the pressure loss coefficient that occurs between concentric and slotted orifice type using CFD softwere. From the observation of pressure loss coefficient values obtained for concentric orifice Fe-37 pressure loss coefficient value of 3.54 with a variation of 5 slotted orifice hole FE-37 type of pressure loss coefficient value of 3.48 and slotted orifice with a variation of 16 holes of type FE -37 at 3.37. Orifice concenctric FE-1602 type of pressure loss coefficient of variation of 2.58 slotted orifice with 5 holes FE-1602 type of pressure loss coefficient value of 2.54 and slotted orifice with a variation of 16 holes of type FE-1602 amounted to 2.43.
