Analisis dan Desain Kondensor untuk Vapor Recovery Unit pada Tangki Penyimpanan Bahan Bakar Menggunakan Simulasi Aspen Plus

Abstract

Currently, human civilization is undergoing a transition toward the use of renewable energy. However, fossil fuels, particularly petroleum, remain the primary energy source worldwide. The global dependence on petroleum is driven by its high energy density, logistical convenience, and relatively abundant availability. As a non- renewable energy source, the world's petroleum reserves will eventually deplete and be exhausted. Therefore, its use must be carried out efficiently and sustainably. One effort to conserve petroleum usage and reduce carbon emissions is by integrating a Vapor Recovery Unit (VRU) into fuel storage tanks. The use of VRUs to recover fuel vapor during the storage process has proven effective in reducing carbon emissions while simultaneously increasing corporate profitability. The condenser component in the VRU system plays a crucial role in the vapor recovery process. The condenser is designed with a vapor recovery capacity of 30 kg/hour and an effectiveness ranging from 90% to 92%, depending on the temperature of the cooling water used. Based on simulations conducted using the Aspen Plus software, the designed VRU system demonstrates optimal performance, particularly when using cooling water at a temperature of 5°C. Under these conditions, the VRU system's effectiveness can reach 95%, meeting the standards set by the American Petroleum Institute (API)
