Shore based small scale LNG/LBG liquefaction unit

Purpose

Innovation of shore-based LNG liquefaction unit which on demand can produce LNG/LBG bunker to the maritime industry.

The liquefaction unit shall be able to connect to the Natural Gas network.
The liquefaction plants shall produce LNG on demand to feed LNG filling/bunkering solutions in Danish Ports.
It will be a modularized design and can be scaled to produce from 20-50 Ton/h.
The plant can, with a add on system, be connected directly to biogas plants and produce LBG direct.
It shall be “intelligent” and function fully automatic with short start-up and shut down cycles

Outcome of project

The collaboration project between Kosan Crisplant, DTU and Moving Energy has developed an energy efficient small-scale LNG/LBG production facility. Based on advanced simulations models created by DTU, used for optimization of the plant layout, a test facility was designed and built by Kosan Crisplant. Kosan Crisplant is now ready to take orders on liquefaction plants from 50 to 150 T/D

Kosan Crisplant and Moving Energy:

Commercial calculation model
Selection and test of critical components
In-house design of cold-box
Layout of a complete liquefaction plant
In-house competence build – technical and commercial
