STORAGE AND TRANSPORTATION OF LIQUID CO

摘要

A system for transportation and storage of liquid CO 2 at low pressures in the region of 1600-2300 KPa comprises a mobile supply tank and an on site storage tank . The mobile supply tank and the on site storage tank are thermally insulated and each tank is refrigerated by a refrigeration system with an evaporator located in the upper gas space of each tank. The on site storage tank is filled with liquid CO2 by a conduit extending from near the bottom of the mobile tank via a filling port on the on site tank to an opening near the bottom of the on site tank. A closed circuit system is achieved by a further conduit extending from the gas space near the top of the on site tank to a gas space near the top of the mobile tank.
