Caloric to supply H₂-generating plant to the Czech Republic

Gerald Ondrey

Caloric Anlagenbau GmbH (Gräfelfing, Germany; www.caloric.com) has won the contract for a hydrogen generating plant with a capacity of 2,000 Nm³/h based on naphtha feed stock. The hydrogen unit will be located in the Czech Republic proving hydrogen to a benzene production unit. The plant design will follow Caloric’s expertise in high efficient and customized concepts. The Basic Design of the plant concept is already finalized and construction has started.

The hydrogen plant is highly integrated into the existing site using utilities and equipment of several other chemical plants. Liquid naphtha is provided from an internal source at site. The raw naphtha needs to be treated in further process equipment supplied by Caloric before using it as feed for the reforming process. Furthermore the tail gas from the pressure-swing absorption (PSA) unit is compressed to undergo an existing carbon dioxide removal unit, as the recovered carbon dioxide is used at site for inertization purposes. The CO₂-free tail gas is send back to Caloric’s reformer for use as fuel. Caloric’s burner — developed in-house — is capable to handle several fuel gases with different heat values, generating low NO_x emissions within the fluegas.

The operation of the plant will start Mid of 2013.
