Hydrogen HTCR and HTCR Twin Plants by Haldor

Application: Produce hydrogen from hydrocarbon feedstocks such as: natural gas, LPG, naphtha, refinery offgases, etc., using the Haldor Topsøe Convective Reformer (HTCR). Plant capacities range from approximately 5,000 Nm3/ h to 25,000+ Nm3/ h (5 MM scfd to 25+ MMscfd) and hydrogen purity from about 99.5 – 99.999+%. This is achieved without any steam export.

Description: The HTCR-based hydrogen plant can be tailor-made to suit the customer’s needs with respect to feedstock flexibility. A typical plant comprises feedstock desulfurization, pre-reforming, HTCR reforming, shift reaction and pressure swing adsorption (PSA) purification to obtain product-grade hydrogen. PSA offgases are used as fuel in the HTCR. Excess heat in the plant is efficiently used for process heating and process steam generation.

A unique feature of the HTCR is the high thermal efficiency. Product gas and flue gas are cooled by providing heat to the reforming reaction to about 600°C (1,100°F). The high thermal efficiency is utilized to design energy-efficient hydrogen plants without the need for steam export. In larger plants, the reforming section consists of two HTCR reformers operating in parallel.

Economics: HTCR-based hydrogen plants provide the customer with a low-investment cost and low operating expenses for hydrogen production. The plant is supplied as a skid-mounted unit providing a short installation time. These plants provide high operating flexibility, reliability and safety. Fully automated operation, startup and shutdown allow minimum operator attendance. A net energy efficiency of about 3.4 Gcal / 1,000 Nm3 hydrogen (361 MMBtu /scf H2) is achieved depending on size and feedstock.
