The PLNG Advantage

The advantages of PLNG over conventional LNG are reduced processing, ease of access to gas as fuel, and most importantly, cost. The CAPEX and OPEX of PLNG is approximately 10% that of LNG. This is Revolutionary!

At -50 C and a moderate pressure of 100 Bar, natural gas (with some solvent added) will fully liquify. The solvent is not discharged with the gas. It is re-used with each refill. The net density of PLNG is approximately 335 kg/m3. This is a little more than 85% the density of LNG stored in a type-C fuel tank. At a lower temperature of -75 C, the net density of the liquified gas is much greater than LNG stored in a type-C tank; it is approximately 450 kg/m3.

With the world’s increasing demand for clean-burning natural gas, there has been a corresponding increase in the demand for LNG. However, the cost of establishing an LNG import terminal is often prohibitive. In such cases, the desire for access to clean-burning natural gas stays just that, a desire. However, using low-cost PLNG technology and CanaGas transport containers, access to natural gas is no longer barred by those that want it.

To safely store PLNG, CanaGas has designed a large type-4 composite pressure vessel. These tanks are sized so that three (3) fit snuggly inside a 40-foot shipping container. The void space is then filled with a fire-retardant polyurethane foam insulation. The pressure vessels are therefore cocooned inside of the steel shipping containers. The resulting gas storage system is robust, modular and, mobile. It is the low-temperature compatibility of these large type-4 pressure vessels that make them ideal for storing PLNG.

At -50 C, a 40-ft PLNG container will store approximately 10 tons of gas (540,000 scf).

At -75 C, a 40-ft PLNG container will store approximately 14 tons of gas (760,000 scf).

Using CanaGas containers, natural gas can be used to:

• Displace Diesel at Mines, Drill-Sites, Frack Sites, & Remote Communities.
• Eliminate of Flaring or Venting of Methane.
• Provide Clean Electrical Power Generation at Strategic Locations.
• Create A Virtual Pipeline (from any source of gas).
• Fuel Trucks, Trains, or Ships.
• Produce Stranded Gas (On-Shore & Off-Shore).
• Export Gas via Road, Rail, or Ship.
