MARINE TRANSPORTATION OF LNG AT INTERMEDIATE TEMPERATURE

The David W. Taylor Naval Ship Research and Development Center, Bethesda, Md., modified commercial equipment and atmospheric pressure so that it can be readily handled without resort to the use of pressure vessels. This practice has the advantage that it requires the use of a minimum of steel in the construction of the vessels used for its containment, but it has a number of disadvantages compared with maintaining the product in the liquid phase at some intermediate temperature and pressure. The article discusses a proposed alternative method that contemplates refrigerating the gas to - 140 degree F, which provides 10 degree F of subcooling. The gas is then loaded into a specially designed marine tanker for shipment to market and then off-loaded to atmospheric pressure where the resulting high enthalpy vapor phase would probably be sent to market, leaving the low enthalpy liquid for storage at atmospheric pressure, although other options exist at the receiving end. These components of the scheme are each discussed in turn.
