Challenge

Access to low-pressure steam and high operating costs are major challenges for CO₂ recovery using MDEA, which typically consumes 1 ton of steam per ton of liquid CO₂. MDEA systems also require complex modifications to hydrogen plants and installation in ATEX zones, often facing licensing hurdles.

Solution

FlashCO₂ was designed to overcome these issues with a simple, end-of-pipe solution that uses PSA off-gas and requires no steam. The unit can be installed outside the hydrogen plant fence, minimizing disruption. An optional PSA can recover up to 10% additional high-purity hydrogen. Steam methane reforming remains the leading hydrogen production method, converting methane and steam into syngas, followed by shift conversion and PSA purification to separate hydrogen from CO, CO₂, and CH₄.
