Penurunan Konsumsi Steam Di PG Modjo-Sragen dengan Konsep Heat- Process Integration Menggunakan Energy Utilization Diagram

Abstract


Sugar factories can meet its own energy consumption, without using other fuels except bagasse, if consumption Steam on Cane (SOC) can reach 40-50% by weight of cane. Sugar factory can do cogeneration and generate electricity which can be sold to the grid if the consumption steam on cane reached a maximum of 40% by weight of sugar cane.
This study aims to reduce the consumption of SOC in the process house using innovation of process configuration. EUD (Energy Utilization Diagram) is a thermodynamic analysis based on the concept exergy. EUD is used to evaluate the configuration process in order to obtain a better configuration of the existing configuration. The study obtained a configuration process with SOC <40%. Evaporation system used a quintuple effect. Vapor # 4 is used for energy donor heater # 1, Vapor # 3 used donor of energy to the heater # 2 and vacuum pan. Vapor # 1 is used for energy donor heater # 3. Exhaust steam pressure of 0.8-1 kg / cm2 is only used in the evaporator # 1.
