Ringkasan
Ethylene Dichloride (EDC) merupakan bahan baku yang digunakan dalam pembuatan Vinyl Chloride Monomer (VCM) pada unit cracking. Sebelum di-cracking EDC akan dilakukan serangkaian proses pemurnian seperti: penghilangan air, pemisahan light Boiling Component (LBC), tower EDC, dan EDC recovery. Pemurnian EDC menghasilkan Light Boiling Components (LBC) dan High Boiling Component (HBC) sebagai produk samping. HBC yang memiliki fraksi besar akan menimbulkan permasalahan pada peralatan seperti fouling. Fouling pada peralatan menghambat proses pertukaran panas, dengan indikasi penurunan nilai overall heat transfer coefficient (U). Pada penelitian ini, proses simulasi ditujukan untuk meningkatkan nilai overall heat transfer coefficient pada reboiler HE-5309 tipe shell and tube. Simulasi yang dilakukan adalah melakukan variasi terhadap static head dan laju steam. Pengaruh dari variasi dapat dilihat melalui analisa regresi berganda. Melalui persamaan regresi berganda ini terlihat bahwa memperbesar nilai static head justru memperkecil nilai overall heat transfer coefficient sedangkan memperbesar nilai laju steam akan memperbesar nilai overall heat transfer coefficient. Melalu hasil variasi diketahui bahwa overall heat transfer coefficient tidak dapat ditingkatkan hingga mencapai 284 Kcal/m2hroC , namun dapat ditingkatkan hingga kisaran 255-268 Kcal/ m2hroC. Kata kunci: Ethylene dichloride, high boiling component, overall heat transfer coefficient.
Ringkasan Alternatif
Ethylene Dichloride (EDC) is the raw materials that is used for manufacturing Vinyl Chloride Monomer (VCM) in the cracking unit. Before the EDC is being cracked, it must be purified on purification unit like: dehydration process, separation of Light Boiling Component (LBC), EDC tower, and EDC recovery. EDC purification produces Light Boiling Components (LBC) and High Boiling Component (HBC) as a side product. If the HBC has a high fraction on it, it will create troubles on the equipment such as fouling. Fouling in equipment will decrease the effectiveness of heat transfer process, and it can be indicated by the value of overall heat transfer coefficient (U) is being decreased. In this study, the simulation is dedicated to increase the value of overall heat transfer coefficient on reboiler HE-5309 shell and Tube by doing some variations against static head and steam flow rate. The impact of the variation can be known by doing the double regression analysis method. Base on the result of double regression analysis, it shows that by increasing the value of static head it will decrease the value of overall heat transfer coefficient and by increasing the value of steam flow rate, it will increase the value of overall heat transfer coefficient. The results of these variations is the value of overall heat transfer coefficient can't be increased until 284 Kcal/m2hroC , but it can be increased in the range of 255-268 Kcal/ m2hroC. Keywords: Ethylene dichloride, high boiling component, overall heat transfer coefficient.
