OPM’s OXPEKK®-SC product provides a sub-micron coating that is highly suitable for carbon capture technologies, able to survive aggressive chemical and thermal environments without inhibiting thermal conduction or fouling chemical reactions necessary for efficient carbon capture.
SOUTH WINDSOR, Conn. (PRWEB) September 14, 2020
Oxford Performance Materials, Inc. (OPM), a materials science company and industry leader in advanced polymers and high-performance additive manufacturing (HPAM®), announced today it has been entered into a Cooperative Research and Development Agreement (CRADA) with ORNL UT-Battelle, Volunteer Aerospace, and RTI International to dramatically improve the energy efficiency of two-phase exchange industrial chemical processes, with a focus on CO2 capturing systems.
“We are extremely excited to be part of this team effort, originally organized by Oak Ridge, to develop technology solutions aimed at mitigating the effects of global climate change,” said OPM Founder & CEO Scott DeFelice. “The goals of this endeavor – to both improve carbon capture system efficiency and reduce capital costs – are essential for broad commercial adoption of these industrial systems, and we are pleased that OPM’s advanced anti-corrosive coating technology is recognized by these industry leaders as part of this solution.”
OPM’s PEKK polymer is highly suitable for carbon capture technologies as it can survive the aggressive chemical and thermal environments typical in such process. In particular, OPM’s OXPEKK®-SC coating product is an aqueous solution that results in a sub-micron coating that protects the metal substrate without inhibiting thermal conduction or fouling chemical reactions necessary for efficient carbon capture. OXPEKK®-SC materials and OPM’s additive process know-how will be applied to protect additively manufactured metallic heat exchangers embedded in the plant-scale process equipment for the purpose of improving thermal efficiency, system reliability, and reduction of operating costs. These capture systems are typically arranged with a packed column within which gases and fluids counterflow in a controlled manner to affect the fluid ‘scrubbing’ the gas to remove a desired fraction. In this case, that captured fraction is CO2 which is prevented from contributing to climate change.
Columns filled with packing materials have traditionally been used to control and facilitate the contact between two phases and thus enhance mass transfer and reaction rates in packed columns used to perform chemical separations such as absorption, liquid extraction, and distillation. Such packing materials must be resistant to the environment in the column. In the case of CO2 capture, which is a self-heating reaction, this is chemically aggressive and warm enough to both corrode lesser alloys and cause degradation of the liquids used in process.
The use of a 3D printed heat exchanger embedded within the packing materials has been demonstrated to aid the management of thermal conditions in the packed column, however this type exchanger is susceptible to corrosion in the environment. The use of OXPEKK®-SC ultrathin coatings both protects these 3D printed metallics from corrosion and, by virtue of coating thickness under 1 micron, allows heat exchangers constructed of alloys with high thermal conduction but low chemical resistance to function properly for long periods without maintenance.
Chemical separations are very common in industrial plants and account for 10–15% of the world's energy consumption. Distillation, for example, is the most commonly employed separation process; however, it is also energy intensive. Therefore, any improvement in the separation/reaction efficiency of a given process has a potentially significant impact on the energy efficiency and economics of the plant.
While several separation and reaction processes including chemical absorption, distillation, and catalytic reactions require or produce heat as a result of an endothermic or exothermic reaction, none of the packings currently available are designed to facilitate heat transfer. In such processes, it is essential that heat transfer is facilitated, and the temperature profile along the column is controlled to optimize the chemical conversion and mass transfer characteristics of the unit operation. Introducing a water-cooled heat exchanger into the column is a straightforward method to manage the heat buildup in an exothermic process. Such an exchanger must be fabricated using thermally conductive materials to effectively conduct heat into the cooling fluid. Typically, alloys are not both highly thermally conductive and highly corrosion resistant. Whereas additives are often used to slow corrosion, this is not an option in these systems, as additives would foul the absorption reaction. Another form of protection is clearly required.
OPM’s OXPEKK®-SC aqueous PEKK coating technology is highly suitable for the targeted energy intensive industrial process that enables thermal transfer while reducing process fouling and corrosion from metallic components. In addition to coating of 3D printed metallic packing, OXPEKK®-SC can coat a wide variety of other metallic components such as valves, pipes and cylinders.
