Hydrogen Recovery Unit

Demand for hydrogen to desulfurize feedstocks and liquid fractions in refining and petrochemical operations is increasing because sulfur in crude oils now being refined is increasing, more heavy crudes with higher carbon-to-hydrogen ratio are being produced, and sulfur specifications in motor fuels are being tightened worldwide.  AET has patented a non-cryogenic, absorption-based process HRU technology that cost-effectively recovers and purifies hydrogen from refinery and petrochemical plant off-gas streams that are currently being consumed as fuel gases.  The AET HRU has the unique and valuable ability to recover 95% of hydrogen contained in a feed gas and produce a hydrogen product stream with 95% hydrogen purity.
