Gasconsult is a chemical engineering company active in technology for liquefaction of natural gas and hydrogen. Gasconsult patents high efficiency, low capex schemes and sells technology licences. 

Regarding LNG, a fundamental feature is that Gasconsult’s processes use the feed natural gas as the refrigerant medium in an optimised system of expanders. This eliminates all refrigerant infrastructure for offloading, storing and blending refrigerants, reducing equipment count and capital cost. It does this in a highly efficient manner. At the highest efficiency end of the market, ZR-LNG+ achieves an efficiency comparable to the dominant DMR (Dual Mixed Refrigerant) and C3MR (Propane pre-cooled Mixed Refrigerant) base load technologies, but with 30-40% less equipment. For conventional mid-scale plants ZR-LNG has a 5-10% higher efficiency and production capacity than the mainstream SMR (Single Mixed Refrigerant) technology but with a 25% lower equipment count. For small-scale plants ZR-LNG has an equivalent equipment count to nitrogen expander technologies but with a significantly higher efficiency and production capacity. These advantages lead to cost, weight and space savings, increased LNG production/revenues and low carbon emissions across the full range of plant capacities.

Regarding hydrogen liquefaction Gasconsult’s OHL process was developed to provide the high energy efficiency and high capacity required to make a meaningful and economic contribution to the scale of decarbonisation inherent in the energy transition. The process achieves a power demand some 40% lower than current new-build practice and is viable at capacities up to 350 tonnes per day (125,000 tpa).

Both the LNG and LH2 technologies enjoy significant patent protection. 

The design and configuration of the LNG and LH2 technologies has been independently validated by McDermott and Costain, leading engineering companies expert in cryogenics.
