Abstract

Formaldehyde is a key industrial chemical known for its high reactivity and broad applicability across sectors such as plastics, resins, textiles, and agrochemicals. Its production has evolved from early silver-catalyzed oxidation of methanol to the more efficient Formox process using iron molybdate catalysts. Despite these advancements, conventional production methods remain energy-intensive, prompting the need for sustainable alternatives. This study investigates the impact of process modification through internal heat recovery on the energy efficiency of methanol-based formaldehyde synthesis. By comparing conventional and modified process configurations, the results demonstrate that reusing reactor-generated heat to power auxiliary units significantly reduces external energy demand. The modified system achieved a 30.64% improvement in energy efficiency, underscoring the potential of heat integration strategies to enhance sustainability and reduce operational costs in formaldehyde manufacturing.
