Techno-economic Assessment of Coal to SNG Power Plant in Kalimantan

Abstract

As the most abundant and widely distributed fossil fuel, coal has become a key component of energy sources in worldwide. However, air pollutants from coal power plants contribute carbon dioxide emissions. Therefore, understanding how to taking care coal in industrial point of view is important. This paper focused on the feasibility study, including process design and simulation, of a coal to SNG power plant in Kalimantan in order to fulfill its electricity demand. In 2019, it is estimated that Kalimantan will need 2446 MW of electricity and it reaches 2518 MW in 2024. This study allows a thorough evaluation both in technology and commercial point of view. The data for the model is gathered through literature survey from government institution reports and academic papers. Aspen HYSYS is used for modelling the power plant consists of two blocks which are SNG production block and power block. The economic evaluation is vary depends on the pay-back period, capital and operational cost which are coal price, and electricity cost. The results of this study can be used as support tool for energy development plan as well as policy-making in Indonesia.

Development of An Integrated Surface and Sub-Surface Simulation Model in A Single Simulation Platform

“…Typical process simulation applications for improving design and solving operational challenges have been reported elsewhere (Putra, 2016a;Putra, 2016b). Development of simulation models have also been applied in different processes (Andika & Valentina, 2016;Bhullar & Putra, 2017;Nayaggy & Putra, 2019).…”

Preliminary Economic Study on the Production of ZnO Nanoparticles Using a Sol-Gel Synthesis Method

“…Although there are many reports confirmed the prospective methods for producing ZnO nanoparticles, there is almost no report on the analysis for the feasibility study in the large scale production. In fact, this information is important for giving better prospective for industrial practitioners to apply the method in realistic application [10][11][12][13][14].…”

Advanced Green Technologies Toward Future Sustainable Energy Systems

“…The energy transition does not only cover the technological aspects, but also combination of economic, socio-cultural, political, and institutional aspects (Child et al, 2018). Therefore, this energy transition should be guided by acceptable agreements and standards toward sustainability and resiliency (Andika and Valentina, 2016).…”
