LPG plant optimization modeling is important to improve overall plant performance. This can be done in various ways, such as increasing efficiency, productivity, and reducing costs. This research aims to obtain the optimum operating design scheme parameters to obtain the best LPG plant unit performance in terms of purity, product yield, energy consumption, and operational economics. Efficiency can be increased by improving production processes and reducing energy consumption. Productivity can be increased by increasing production capacity. In this research, the analysis method used involves a comparison between the LPG Plant unit design before and after optimization with field operational data, as well as data from literature studies. The factors that influence this difference include the value of equipment prices, the number of equipment, excessive utility consumption, and total sales of LPG production. Based on economic calculations, Scheme 1 has a Total Capital Investment (TCI) of $ 3,317,566.18, annual costs of $ 219,008.7346, and income of $ 125,666,446 (compared to scheme 2, which is $ 131,909,910.33), and LPG processing costs of $0.0199 per kg. By looking at the comparison of the performance and economic value of the two schemes, it can be concluded that scheme 1 is a superior concept for LPG production units because it has been considered from various aspects.
