Heat Recovery and Heat Upgrade
Publieke samenvatting / Public summary
Aanleiding
Philip Morris Investments B.V. (PMI) has a large factory in Bergen op Zoom, the Netherlands for the production and distribution of Semis Tobacco components and logistics hub supporting all of EU operation. Philip Morris has strong global commitments towards energy and carbon savings, such as achieving carbon neutrality in all manufacturing sites (scope 1 and 2) by 2025 and across the entire value chain by 2040. In that regard, detailed emission saving studies have been conducted at the Bergen Op Zoom facility. This triggered the idea that, although a great part of the residual process heat is already recuperated and re-used, the remaining residual heat streams could potentially be re-used for building- and process/cleaning water heating. Therefore, PMI will initiate an investment project to recover and upgrade heat from two sources in the factory where currently the energy is released to the outside atmosphere.
Doelstelling
In earlier projects, PMI invested in equipment to capture residual heat and produce high quality steam. As there is still lower temperature residual heat available after this step, PMI will follow up with additional carbon emission reducing measures. The goal of this project is to capture residual heat streams from the production processes and re-use the residual heat in the most optimal way for heating hot process/cleaning water and (industrial) buildings. Currently, steam generated by Natural Gas boilers is used for these heating applications. The project will contribute to both PMI's commitments towards energy and carbon savings as well as the Dutch climate goals.
Korte omschrijving
To achieve the CO2-emmision reduction, by minimizing steam usage generated with natural gas, PMI aims to recover residual latent heat, and upgrade temperature with heat pumps. The project is based on few interconnected measures: 1. Recover energy from process furnaces flue gas, into a closed loop water system at 55°C. 2. The 55°C water originating from the two processes is fed into a high temperature heat-pump. Energy is transferred from this heat source, and cooler 40-45°C water is pumped back to the heat recovery system to capture more waste heat. 3. Energy from the 55°C heat source is transferred to the hot side (heat sink) of the heat-pump where it will create water of 85°C. This is 85°C water is pumped to the factory main hot water distribution system, currently utilising steam heating. 4. The 85°C water transfers energy to the factory main hot water system and returns to the heat pumps at 70-75°C, where temperature is increased again by transferring heat originating from the energy recovery systems (e.g. the 55°C water loop).
Resultaat
The implementation of the above measures will minimize usage of steam generated in natural gas powered boilers and replace it with heat currently wasted to the outside air. With the described investments PMI will reduce the annual CO2-emmisions by 1.503 ton due to replacing consumption of natural gas (10.467 MWh) with green electricity (2.093 MWh) by recuperation of residual heat.
