Analysis of water and electricity consumption of urea fertilizer industry: case study PT. X

Abstract

Urea fertilizer industry is one of the many industry sectors that require water and electrical energy. The use of water in the fertilizer industry increases with the increasing demand for fertilizers. Therefore, to meet the needs of water and electricity, fertilizer industry builds river water treatment plants into clean water by using coagulation, flocculation and filtration. Unit power plant using gas turbines with natural gas fuel with a total design capacity of 67 MW. The purpose of this study was to estimate the consumption of water and electricity in urea fertilizer industry. The method used in this research is quantitative descriptive. This study showed total urea production in 2018 amounted to 2,170,100 tons with total water consumption by 27,742,225.4 m3 (equivalent 12.8 m3/ton of urea) and electricity consumption amounted to 376,979,956 kWh (equivalent to 173 kWh/ton urea). The result of highest percentage of water allocation is 45% for the process unit and electricity allocation is 36% for the utility unit.
