A new way to liquefy natural gas using only moderate pressure (80 to 90 Bar) and conventional refrigeration (-50 C to -70 C). Compared to conventional LNG, OPEX costs to liquefy natural gas as Pressurized-Liquefied Natural Gas (P-LNG) are reduced by 75%. CAPEX costs are slashed by 90%. No “stripping” of the gas is required. Only de-hydration.
To safely transport P-LNG, three (3) CanaGas type-4 tanks are installed inside of a standard intermodal shipping container to create an Intermodal Transport Module (ITM). An ITM will carry up to 13 MT of natural gas as P-LNG. Transportation costs are kept low as ITMs will use the world’s existing intermodal infrastructure; trucks, trains & container ships. Container ships will be chartered by CanaGas for large volume marine transport.
Due to the low cost of liquefaction, the capture and monetization of large flare gas is made practical and economically feasible.
The same 100-Bar ITMs will second as fuel containers for ships or trains. At loading, P-LNG can be made from LNG or CNG.
The same ITMs will also make small-scale biogas practical and feasible. Biogas can be economically produced from farms, feedlots, forestry operations, landfills and sewage treatment facilities where a tie-in to a natural gas pipeline is not available.
Using advanced engine technology, the biogas can be used to generate electricity. The gas is only partially stripped of CO2. Remote biogas production will help to decrease energy poverty in the world, especially in Africa, India, and Asia.
For the separation of CO2 from biogas, CanaGas has new IP to make the process low cost with a small footprint.
The same ITMs can be used to transport natural gas in one direction, and liquid CO2 for sequestration in the other direction. No cleaning of the tanks is required at either end.
Similar ITMs at 50-Bar will safely transport liquid CO2, ethane, and ethylene. Propane may be transported in 15-Bar ITMs. For the liquefaction of these other gaseous fluids, refrigeration and dehydration is not required.
For the safe and intermodal transport of ammonia to be used as fertilizer or fuel, CanaGas offers its 7-Bar ITMs.
