[ABSTRAK Tulisan ini membahas ruang lingkup tahapan pemisahan (distilasi), sebagaitahapan yang penting dalam pemisahan komponen agar mendapatkan komponenyang murni. Dalam tahapan distilasi ini, terjadi perbedaan yang dipengaruhi olehtekanan, temperatur, konsentrasi, dan kecepatan. Penelitian ini bertujuan untukmenganalisa nilai kehilangan eksergi di setiap tray pada konfigurasi tertentu darisetiap pemisahan multikomponen. Komponen yang dipisahkan dari kilang LNGberupa metana, etana, propana, n-butana, i-butana dan i-pentana. Data eksperimenkhususnya komposisi untuk komponen yang dipisahkan tersebut diperoleh daripenelitian sebelumnya. Metode perhitungan yang digunakan mengacu padapenelitian sebelumnya. Konfigurasi pemisahan komponen berdasarkan titik didihmenghasilkan exergy loss sebesar 9.220,57 MW. Utility cost yang dibutuhkanuntuk kondensor sebesar US$ 6.892.639 dan untuk reboiler sebesar US$ 11.054.Konfigurasi pemisahan komponen berdasarkan fraksi terbesar menghasilkanexergy loss sebesar 12.582,29 MW. Utility cost yang dibutuhkan untuk kondensorsebesar US$ 6.898.806 dan untuk reboiler sebesar US$ 19.382. Konfigurasipemisahan komponen berdasarkan equimolar menghasilkan exergy loss sebesar23.012,08 MW. Utility cost yang dibutuhkan untuk kondensor sebesar US$6.900.682 dan untuk reboiler sebesar US$ 21.939.Semakin kecil nilai exergy lossakan semakin kecil pula utility cost yang dibutuhkan. ABSTRACT This research discusses the scope of phase separation (distillation), as animportant stage in the separation of components in order to obtain a purecomponent. In this distillation stage, there is a difference which is affected bypressure, temperature, concentration, and speed. The main goals of research on thesimulation of distillation is to analyze exergy loss in each configuration formulticomponent separation. Component will be separated from LNG Plant aremethane, ethane, propane, n-butane, i-butane, and i-pentane. Experiment dataforcomposition of the separated components written by previous researcher. Themethod is arranged by previous researcher. Configuration component separationby boiling point has produced exergy loss of 9.220,57 MW. Utility cost requiredfor the condenser of US$ 6.892.639 and for the reboiler of US$ 11.054.Configuration component separation by the largest fraction has produced exergyloss of 12.582,29 MW. Utility cost required for the condenser of US$ 6.898.806and for the reboiler of US$ 19.382. Configuration component separation byequimolar has produced exergy loss of 23.012,08 MW. Utility cost required forthe condenser of US$ 6.900.682 and for the reboiler of US$ 21,939. If the valueof exergy loss is small, It will be needed utility cost that small too.;This research discusses the scope of phase separation (distillation), as animportant stage in the separation of components in order to obtain a purecomponent.
