Waste heat recovery unit for industrial processes
In many industrial settings, large amounts of heat generated during production or gas cleaning processes often go unutilized. This results in wasted energy and increased operational costs. Capturing and reusing this waste heat can significantly improve efficiency and sustainability.
Recover and utilize waste heat efficiently
The Waste Heat Recovery Unit (WHRU) by GEA is designed to capture waste heat from industrial processes and transform it into usable energy. This unit features a series of tube banks, which vary based on the required cooling temperature. These tubes contain a carrier fluid that absorbs heat with high efficiency, allowing the WHRU to provide versatile configurations, including the integration of an Organic Rankine Cycle (ORC) module for converting heat into power or other valuable energy sources. The WHRU operates on a counterflow design, where the gas enters from the top and exits at the bottom. When dealing with crude gas, the addition of lime hydrate helps to prevent the formation of sodium pyrosulfate and sodium bisulfate on the tube banks. A ball cleaning system using metal balls in a closed cycle ensures that substances do not accumulate on the tubes. GEA’s WHRU is highly serviceable and flexible, making it suitable for retrofitting in narrow spaces, thus enhancing its applicability across various industrial scenarios.
