LNG, methanol and ethylene plants

Production and storage of cryogenic substances such as LNG, methanol or ethylene would not be possible without special insulation systems. KAEFER offers several systems which can withstand extreme thermal and mechanical pressures. They minimise evaporation rates, thereby ensuring the production and storage of these liquefied sources of energy is economically viable.

The large-scale Snøhvit project on a gas liquefaction plant in Norway was not the first example of the challenges involved in the liquefied gases business. Many years ago we bundled our expertise in this sector and formed a LNG Corporate Competence Centre. The skills developed here in insulation systems for liquefied gases now benefit all KAEFER divisions.

Our capabilities in LNG, methanol and ethylene plants include installing heat and cold insulation, prefabricating components, scaffolding and surface protection work.

The transportation of cryogenic substances requires very high-performance insulation. We offer two distinct insulation systems to cope with different temperatures and individual pressures. A multilayered insulation system allows LNG to be carried in pipes at temperatures of -163 °C. For the cost-effective transportation of substances at higher temperatures, e.g. ethylene, a detached insulation system of polyisocyanurate foam (PIR) is used.

Both systems guarantee that the surface remains free of condensates, that heat flows as required and that the insulation system functions safely within the defined parameters.
