The rise in awareness of global warming has created heightened consumer, regulatory, and industry interest in clean forms of energy generation. Specifically, the impact on the natural environment from the burning of fossil fuels has brought increased attention to technologies that capture carbon dioxide from flue gas.
A number of projects are in development around the world that aim to utilize more energy efficient absorption processes for the capturing of carbon dioxide from flue gases. These pilot projects are for very large scale carbon capture and storage applications. However, for smaller scale carbon capture applications, Union Engineering already has developed and supplied fully proven and commercialized technologies and is constantly improving their technology for the recovery of carbon dioxide from flue gases. This technology can be used in a number of applications where the benefits are truly cleantech, meaning that the technology will improve operational performance, productivity, and efficiency while reducing costs, inputs, energy consumption, waste, and pollution.
THE CAPTURING PROCESS
With capture plants from Union Engineering, carbon dioxide can be recovered from any gas stream based on the combustion of fossil fuels, including coal, heavy fuel oil-fired steam boilers, and natural gas-fired combustion engines. Moreover, the technology can be used to capture carbon dioxide from nonpower generation sources, like lime kilns.
The capture plants from Union Engineering are based on the most well proven absorption technology currently available on the market, namely monoethanolamine (MEA). MEA is a primary amine that reacts readily with carbon dioxide. Since the reaction is purely chemical absorption it works well with gas streams having low partial pressure like CO2. Low partial pressures are typical in flue gas.
