This article analyzes the effective use of energy media generated during the production of propylene glycol from distilled glycerin, with particular focus on thermal energy losses arising from process steam released in the hydrogenation stage. In the current system, this steam is vented to cooling towers, causing significant energy losses and high electricity consumption by the cooling infrastructure. The aim of the study was to identify and assess solutions enabling the recovery and reuse of process steam within the plant’s internal energy system. Two variants were examined: injecting steam into the main steam pipeline and using it in a heat exchanger to preheat raw materials. For each option, mass and energy balances as well as technical and economic analyses were performed. The results indicate that injecting steam into the main pipeline is the most advantageous solution. It is characterized by simple implementation, low investment cost (about PLN 48,000), and a very short payback period of approximately two to three weeks of plant operation. The solution also reduces electricity consumption and CO₂ emissions. The proposed modernization demonstrates a practical approach to improving energy efficiency in chemical production and supports sustainable development objectives related to rational energy use and environmental protection .
