Hydrogen For Ammonia And Syngas Plants
Hydrogen Plants for Refineries
Hydrogen Plants for Refineries
Hydrogen can be recovered separately, of course, from the syngas mixture and purified through the PSA process to yield a high-purity hydrogen product stream for use in refinery hydro processing units or petrochemical plants. In fact, KBR has worked on the design and/or construction of over 34 low-energy, low-cost refinery hydrogen plants using proprietary KBR natural gas reforming technologies. The innovative, cost-effective synthesis gas (syngas) production technologies and hydrogen production technologies KBR offers include: the KBR top-fired steam methane reformer (SMR) and the KBR Reforming Exchanger System (KRES™).
KRES for Refinery Hydrogen Plant Revamp
Commercial Applications
KBR KRES reforming exchanger technology can be used to revamp an existing steam methane reforming (SMR) hydrogen unit in a refinery to increase hydrogen production capacity by up to 35%. The KRES add-on unit can be erected in a relatively small plot space of 15'x15' and piped in parallel to the refinery hydrogen plant SMR while the existing SMR unit continues to operate. Piping tie-ins to the existing hydrogen plant can then be made during a relatively short turnaround. Some process heat exchangers will likely need to be supplemented with parallel units or replaced during the turnaround; this will be evaluated during the KRES revamp study for the refinery hydrogen plant.
Values & Benefits
A KRES for refinery hydrogen plant revamp can be achieved for less cost and while reducing both steam export (if desired) and NOx & CO2 emissions versus adding tubes to the existing SMR furnace or building a secondary SMR. Refineries typically do not have available plot space to erect a second SMR and the conventional revamp options of completely retubing or expanding the existing SMR furnace can require a lengthy turnaround and incur significant lost production. If you require less than a 35% expansion of existing refinery hydrogen production capacity, you should contact KBR to discuss a KRES for refinery hydrogen plant revamp.
