Abstract

Bejana tekan (Pressure Vessel) adalah elemen penting yang terdapat dalam dunia industri khusunya digunakan untuk migas,petrokimia dan pembangkit listrik. Bejana tekan (pressure vessel) adalah tempat penampungan fluida berupa cair maupun gas dengan tekanan yang lebih tinggi dari tekanan atmosfir. Pressure vessel harus dirancang dapat menahan berbagai macam tekanan contohnya tekan yang terjadi didalam pressure vessel (internal pressure) dan tekanan akibat dari ataosfer (external pressure). Perancangan pressure vessel harus dapat menahan dua macam tekenan tersebut. pressure vessel akan mengalami kerusakan jika tidak dapat menahan tekanan internal maupun eksternal. Ledakan dari bejana tekan ini disebabkan banyak faktor salah satunya yaitu tekanan yang beroprasi pada pressure vessel melebihi tekanan yang diijinkan oleh pressure vessel. Namun ada juga pressure vessel yang mengalami kerusakan akibat tidak dapat menahan tekanan eksternal. Oleh karena itu dalam perancangan pressure vessel harus memperhatikan tekanan internal maupun tekanan eksternal. Penelitian ini diawali dengan langakah awal yakni membaca studi literatur dan pengumpulan data yang berkaitan dengan pressure vessel C-064-11. Pressure vessel C-064-11 memiliki kriteria seperti plat yang digunakan yaitu SA-516 Gr 70, memiliki panjang tangent line to tangent line (TL to TL) sebesar 221,7 in, memiliki diameter 78,74 in dan jenis penutup ellipsoidal. Langkah selanjutnya menentukan ketebalan dengan melihat tekanan internal yang dapat dilihat dari datasheet sebesar 128,01 psi maka akan didapatkan ketebalan minimum dinding dan penutup pressure vessel sebesar 0,59 in atau memiliki ketebalan 15 mm. Hasil ketebalan tersebut akan diuji apakah ketebalan mampu utnuk menahan tekanan internal sebesar 128,01 psi dan tekanan eksternal 1 ata. Dari hasil peneletian yang dilakukan dapat dikatakan aman jika hasil dari desain kriteria pressure vessel melebihi tekanan internal sebesar 128,01 dan tekanan eksternal 1 ata dan hasil distribusi tegangan memiliki nilai dibawah tegangan ijin.

Pressure vessels are important elements in the industrial world, especially those used for oil and gas, petrochemicals and power plants. A pressure vessel is a reservoir for fluid in the form of liquid or gas with a pressure higher than ataospheric pressure. Pressure vessels must be designed to withstand various kinds of pressure, for example pressure that occurs inside the pressure vessel (internal pressure) and pressure due to the ataosphere (external pressure). The design of the pressure vessel must be able to withstand these two types of pressure. The pressure vessel will be damaged if it cannot withstand internal or external pressure. The explosion resulted in many casualties, injuries and material losses. The explosion from this pressure vessel is caused by many factors, one of which is the operating pressure on the pressure vessel exceeding the allowable pressure by the pressure vessel. But there are also pressure vessels that are damaged due to being unable to withstand external pressure. Therefore in designing a pressure vessel must pay attention to internal pressure and external pressure. This research begins with the initial steps, namely reading literature and collecting data related to the pressure vessel C-064-11. Pressure vessel C-064-11 has criteria such as the plate used, namely SA-516 Gr 70, has a tangent line to tangent line (TL to TL) length of 221.7 in, has a diameter of 78.74 in and has an ellipsoidal cover type. The next step is to determine the thickness by looking at the internal pressure which can be seen from the data sheet of 128.01 psi, so you will get a minimum wall thickness and pressure vessel cover of 0.59 in or a thickness of 15 mm. The results of the thickness will be tested whether the thickness is able to withstand an internal pressure of 128.01 psi and an external pressure of 1 or more. From the results of the research conducted, it can be said to be safe if the results of the pressure vessel design criteria exceed the internal pressure of 128.01 and the external pressure of 1 or more and the results of the stress distribution have a value below the allowable stress.
