2020 REFINING PROCESSES HANDBOOK PROCESS CATEGORIES COMPANY INDEX HYDROGEN GENERATION Cryocap™ H₂-Cryogenic CO₂ Separation Application: CO₂ capture from H₂ production plants Feedstock-Offgas from H₂ plant Description: The offgas is compressed, dried and sent to a cryogenic unit, where the CO₂ is separated from the other components by a combination of partial condensation and distillation. A pure and pressurized CO₂ flow is produced from the cold box. The non-condensed gases are recycled through a membrane system to recover H₂ and CO₂. Residual gas is sent to the burners of the reformer. The CO₂ product is compressed up to supercritical pressure or liquefied and stored in liquid storage. Food-grade quality can be achieved by an additional purification on a catalytic bed where all remaining hydrocarbons and alcohols are destroyed. Cryocap™ H₂ can be installed for greenfield as well as brownfield H₂ plants. Products: CO₂; co-product: H₂ H2 product Natural gas SMR Schift H2 PSA Cryocap™ H2 Fuel Membranes Cold box CO2 product Residue to fuel gas Advantages: Cryocap™ H₂ can be installed for greenfield as well as brownfield H₂ plants. Main feature: * More than 98% of CO₂ recovery from syngas Economics: OPEX + CAPEX: * $45/tonne of CO₂ * Increase H2 production by 13%-20% * Cryocap™ H₂ offers the lowest costs for CO₂ production from H₂ plant (20% less CAPEX than amines) Licensor: Air Liquide Engineering & Construction Website: https://www.engineering-airliquide.com/cryocap-h2-cryogenic-co2separation Contact: cryocap@airliquide.com Utilities: Capacity: From 500 tpd-2,000 tpd Installations: 1 (100,000 tpy) Copyright © 2020 Gulf Energy Information.
