That convinces also customers in remote areas: In December 2014, Governor Viktor Basargin launched the first liquefied natural gas (LNG) production plant of Russia’s Perm region. A plant, that was planned and manufactured in Wurzen. With a production capacity of about 1.5 t/h, it supplies more than 2, 000 households and farms in the region with energy. On behalf of the operator company ­Gazprom, Cryotec engineers delivered two liquefaction plants, storage facilities as well as a filling for tankers. The gas of the plant is tapped from a central gas line and then will be liquefied with a temperature between -162 and -165 °C (-259.6 and -265 °F, respectively) in the plant.

And what about a later modification or capacity expansion? “This is a specialty of the building-block approach,” explains Cryotec’s Managing Director Corinne Ziege. Further modules can be simply added to the existing ones to ramp up capacities — “numbering up” instead of the classical scale up procedure.

Compact Design, Small Footpirnt: Benefits of Modularisation

The compact design with its small footprint, flexibility and the opportunity to construct the production assets in the warm and safe environment of the Cryotec yard was especially important for a site which operates at a remote location in central Russia, where temperature in January can fall below -40 °C (-48.8 °F).

Further, the approach helped to accelerate on-site works and commissioning as well as to minimize time-to-market as all necessary tests could be conducted in advance at the manufacturer. All this makes LNG a perfect, yet challenging, playing field for modular plant construction. And Cryotec promises to deliver: tank storage facilities, transport infrastructure, cogeneration units and — of course — liquefaction plants.

The company engineers build production facilities with capacities ranging from 1, 000 kg/h to 10, 000 kg/h and more. Be it as containerized plants — which can be transported to remote locations — or as skid mounted installations, which combine the benefits of a modular design with simple maintenance, due to the open skid architecture.

Beyond the Engineering Construction Kit

But of course, Cryotec also offers tailor made stationary designs, which are assembled directly at the customer’s construction site. And that’s not all: In addition to the planning and supply of the main technical equipment, EPC Engineering & Technologies also provides the planning services for the infrastructure, media supplies, construction planning, auxiliary systems, control systems as well as pipes, energy optimization/management, and finance planning, and supervises the local contractors. No wonder, that modular engineering fits right into the Henkels vision of a “functional turnkey” approach.
