Correlating the additional Amine sweetening cost to acid gases load in natural gas using Aspen Hysys
Journal of Natural Gas Science and Engineering, 2014Co-Authors: Ayyaz Muhammad, Yasser GadelhakAbstract:Abstract Natural gas with high acid gas contents represents a challenge in process engineering and energy industry. Exploring the alternative solutions requires correlating additional costs accompanying the process scale-up to treat high acid-gas contents. This work estimates this relation and validates it against various conditions in Amine sweetening plants. An Amine sweetening process was simulated using Aspen Hysys to treat a natural gas (25 MMSCFD, 1.7 mol% H 2 S and 4.13 mol% CO 2 ). Amine circulation rate, lean Amine temperature, re-boiler temperature and Amine concentration were chosen as the main input variables to optimize the process total cost using the central composite experimental design model. The process was scaled-up to handle a sour gas up to (25 mol% CO 2 and 3 mol% H 2 S) by scaling up the Amine circulation rate. The capital and operating costs showed a linear relationship with the increase of CO 2 percentage in natural gas. Moreover the utility requirements, regenerator column diameter and the surface area of the re-boiler, the lean-rich Amine heat exchanger and the lean Amine Cooler showed a strong linear increase correlation. There was no statistical difference using either Li–Mather or Kent–Eisenberg thermodynamic models. Low feed gas pressure yielded a similar linear relationship irrespective of the costs for purchasing and operating the inlet compressor and air Cooler. No statistical difference found between cost regressions lines of different tray efficiency of the distillation tower. For various partial pressures of CO 2 and H 2 S, assuming no other sulphur compounds, the economics scaled up as a second order polynomial.

analisa kegagalan patah pada lean Amine Cooler fan 135 h 04 pt hess indonesia pangkah ltd
Wahana Teknik, 2013Co-Authors: Sunarto Sunarto, Teguh NugrohoAbstract:Dalam dunia industri, lazim digunakan berbagai alat pemindah panas atau heatexchanger. Ada beberapa jenis heat exchanger yang sering digunakan, antara lainmenggunakan hembusan udara, mengalirkan pada air, dll. Tugas akhir ini membahas salah satu jenis heat exchanger yaitu dengan menggunakan aliran udara (Air Cooled Heat Exchanger / ACHE). Untuk dapat menghembuskan udara diperlukan baling-balingyang biasa digerakkan oleh motor terhubung oleh sabuk (belt). Istilah umum yang sering dipakai untuk pendingin dengan baling-baling ini adalah Cooler Fan. Terdapat kasus yang terjadi pada sebuah instalasi di PT. HESS Indonesia Pangkah Ltd. yaitu kipas pendingin Lean Amine ( Lean Amine Cooler Fan / 135 H 04 ) yang mengalami patah pada bilah baling-balingnya. Kejadian patah yang terjadi beberapa kali dengan modus yang sama, tentulah sangat merugikan industri. Oleh karenanya jurnal ini dirasa cukup penting untuk memberikan sedikit solusi demi tercapainya kehandalan peralatan industri. Yang tentu akan berimbas pada meningkatnya produktifitas. Akan dijelaskan mengenai landasan teori, faktor penyebab kegagalan, analisisa kegagalan dan penyelesaiannya. Hasil studi kasus ini diharapkan bermanfaat untuk kemudian dapat diterapkan dalam Cooler fan yang lain. Kata kunci: Air Cooled Heat Exchanger, Cooler Fan, analisisa kegagalan
