Abstract

The increasing demand for sustainable chemical processes has sparked interest in designing green chemical plants. One promising approach is the production of formic acid (HCOOH) through the hydrogenation of carbon dioxide (CO₂) derived from methane sourced from biogas. The methane undergoes steam methane reforming, producing hydrogen (H₂) and CO₂. This study presents the design of a green formic acid plant utilizing CO₂ as a feedstock, contributing to the reduction of greenhouse gas emissions and promoting carbon recycling. The biogas, derived from organic waste, is purified to isolate CO₂, which is then hydrogenated via a catalytic process to produce formic acid. The plant's design includes detailed considerations of reactor selection, heat integration, and energy efficiency to minimize environmental impact while maximizing production output. The economic feasibility and environmental benefits are assessed, demonstrating that this method not only offers a pathway to sustainable chemical production but also contributes to carbon capture and utilization efforts. This green process holds potential for industrial applications, fostering the development of a circular carbon economy. The main processes utilized in this plant include CO₂ hydrogenation, steam methane reforming, carbonation, and decomposition of Na₂CO₃. The plant produces formic acid, widely used in industries such as rubber, textiles, pharmaceuticals, cosmetics, animal husbandry, leather tanning, and more. Additionally, the plant generates by-products such as soda ash (Na₂CO₃) and hydrogen. The plant will be built in Mojokerto, East Java, in 2026 with a two year construction period. It will operate continuously with a biogas feed capacity of 957.86 kg/hour and NaOH at 1182.09 kg/hour, yielding 3380 tons/year of HCOOH and 792 tons/year of H₂. Based on the comprehensive analysis conducted, it can be concluded that this plant is feasible for investment and construction.
