HTCR characteristics

The Haldor Topsoe convection reformer concept (HTCR) is characterised by compactness, fast load response and effective heat transfer.

HTCR is a flue gas heated steam reformer system with a high degree of internal heat recovery and a compact layout making it highly efficient. The reformers are well suited as standalone units or as revamp options for capacity increase of existing plants.

The HTCR principle

HTCR consists of a number of bayonet reformer tubes contained in a refractory-lined vessel. The process feed is distributed to the catalyst-filled annular spaces in the tubes via a header arrangement. After passing the catalyst, the gas leaves the tubes via the bayonets and is collected in an outlet header system.

Heat for the reforming reaction is supplied mainly by flue gas flowing upwards on the outside of the reformer tubes as well as by the reformed gas flowing upwards through the bayonet.

Scope of supply

The unit may be skid-mounted: A movable "plug-in" style unit which can be transferred from one site to another depending on local hydrogen requirements.

Topsoe's convection reformer concept can be delivered with a full scope of supply including process license, basic and detailed engineering, equipment and materials, catalysts, site supervision and operator training. The scope of supply is tailored according to clients' needs.

Market experience

Topsoe has designed and suppiied more than 30 HTCR plants with capacities ranging from 5,000 to 30,000 Nm3/h (4.5 to 27 MMSCFD).
