Loughborough University in the UK is engaged in Carbon Sequestration research – looking into ways of storing carbon dioxide deep into the Earth where the pressure will prevent its leakage into the atmosphere. This CO2 research Case Study describes how an Equilibar ULF1 Research Series back pressure regulator successfully solved problems that traditional BPRs experienced in demanding supercritical CO2 service.
