The game changer two stage micro liquefaction unit for (bio) lng
EC through its Renewable Energy Directive mandates that 10% of the transport fuels in 2020 will come from renewable sources, focusing on a minimum 35% reduction of Greenhouse gas (GHG) emissions. Towards that direction, LNG and Bio-LNG are expected to play a pivotal role in Europe’s comprehensive renewable fuel strategy for the transition to a low-carbon transport sector.  Micro (Bio) LNG (production capacity 0.1-30 tons/day) refers to its direct use of (Bio) LNG in its liquid form as a transport fuel, contrary to its traditional regasification and subsequent introduction into the gas grid. Nevertheless, currently liquefaction is part of an integrated big scale distribution system, taking place in large scale facilities. This kind of facilities is highly CAPEX intensive, require long realization time (up to 72 months) and are only profitable at large scale (min. 2000 Nm3/h inlet gas flow). Thus, the market demands small liquefaction systems able to fulfil the gap among big producers and small consumers.   Current competitors (mainly EU based) offer different single stage liquefaction solutions which result either to lower conversion efficiencies, higher energy consumption or require considerable higher inlet gas flow (>500 Nm3/h) and use of consumables.   We provide a proprietary Micro Liquefaction Unit - MLU250 - able to treat methane streams for producing LNG as clean fuel for transportation with the following key advantages over Micro-Liquefaction systems using natural cooling media:  - Cost-efficiency: “Plug and play”, modularized set up with 25% lower investment needs and accelerated construction schedules.  - Energy efficiency: Low energy use for feedgas liquefaction without liquid N2 use, being from 7% up to 64% more efficient than alternatives.  - Operators can easily add capacity up to 25 tons/d with small modular units (250 Nm3/h).  - Remote accessibility: Enables monetization of small (bio)gas plants, impossible until now.
