PRARANCANGAN PABRIK DELAYED COKING BERBASIS SHORT RESIDU CRUDE OIL DENGAN KAPASITAS 100.000 BPSD

Abstract

Delayed coking is a hot cracking process for the breakdown of long-chain hydrocarbons into short-chain hydrocarbons, which have higher economic value. The delayed coking unit is divided into three main processes, namely the heating process, coking process, and fractionation process. The heating process is carried out to increase the temperature of the raw material according to the coking reaction that occurs. The coking process occurs in the coking drum to produce short-chain hydrocarbon products and coke as a by-product. Coke accumulates in the coking drum, and short-chain hydrocarbons enter the fractionation tower. In the fractionator, the product will be separated according to the boiling point range of the product. The delayed coking plant from residue oil is planned to operate in the Kariangau Industrial Estate, Kariangau Village, West Balikpapan District. This factory is designed to be able to accommodate xiii short residue oil raw materials in the form of LSWR of 100,000 BPSD. The factory involves 206 business activity personnel from different specialties and abilities and covers an area of 112,796 square meters. Establishing the factory requires a Total Capital Investment of IDR 1,692,279,594,572.47. Based on the economic evaluation, the parameter values of Return on Investment (ROI) 62.654%, Payout Time (POT) 1,60 years, Break Even Point (BEP) 27,81%, Shut Down Point (SDP) 25.72% and Discounted Cash Flow of 13.02% which is greater than the MARR value. From this economic review, it can be concluded that a delayed coking plant based on the short residue crude oil is feasible to set up.
