CO₂ gas from any emission source is captured using different technologies. Once captured, the gas is usually saturated with water and, depending on the end use, needs to be removed to concentrations as low as 0.1 ppmv.
BCCK’s four decades’ worth of field experience and a strong research-driven approach have led to the development of technologies to purify the captured CO₂.
BCCK’s dehydration portfolio consists of:
Molecular Sieve-based Dehydration
- BCCK’s molecular sieve-based dehydration solutions are highly regenerative and efficient for low outlet dewpoint application (<0.1 ppmv). We have a strong, ever-growing network of adsorbent vendors who work with us to provide the most effective and cost-competitive project-driven solutions. Integration with upstream compression and multiple regeneration options have led to optimized designs to reduce the system’s overall capital and operating costs.
Glycol-based Dehydration
- BCCK’s glycol (TEG)- based solutions are regenerative and OPEX-friendly for applications requiring water removal down to 20 ppmv. BCCK’s glycol systems are designed to minimize the use of makeup TEG and utilize waste heat from upstream/downstream sources to limit the use of energy for regeneration.
Molecular Sieve-based Dehydration
- Regenerative design
- A molecular sieve or equivalent adsorbent
- Saturated inlet water concentrations
- Careful selection of Material of Construction (MOC)
- <0.1 ppmv outlet water concentration
- Excellent scalability (100 SCFM minimum)
- No emissions
- Integration with upstream compression for reduced OPEX.
Glycol-based Dehydration
- Regenerative design
- Solvent-based absorption process
- Triethylene Glyccol (TEG) solvent
- Removes water down to 20 ppmv
- Random/structured packing within the tower for mass transfer
- Very low OPEX
- Can remove water from saturated gas streams at high temperatures
- Optimized designs to reduce consumption of make-up TEG
