TANK CONTAINER FOR TRANSPORTATION OF LIQUIFIED GAS

摘要

A General-Purpose Multimodal Transportation Container (GPMTC) for transportation and storage of hazardous cargoes is fitted with a reservoir (1), a level sensor (5) installed downright and passing through the vertical centerline and the horizontal centerline of the reservoir (1)and with a pressure sensor (6), a liquid phase density sensor (8), a vapor phase density sensor (9), a temperature sensor (7) and a set unit (10) of gyros and the accelerometers. The said group of sensors (5-9) is used to measure such main physical parameters as the pressure, the density of the liquid phase, the density of the vapor phase, the temperature of the liquid and vapor phases at several points, the level of separation of the liquid and vapor phases, the displacement vector, and misalignment of the GPMTC's base with the horizontal plane. This data is necessary for a Central System Unit (11) to calculate the volume and mass of the liquid and vapor phases and the total mass of cargo. These sensors and telemetry equipment are triggered when the circuit is closed and opened at the moment of opening and closing of the GPMTC's shut-off valves and provide measurement data which allow in real time and anywhere in the world carry out metering and calculate the mass of gas, taking into consideration the vapor phase, at the beginning and end of the cargo operations with accuracy meeting the requirements of commercial metering. Also, this GPMTC is fitted with GPS devices with telemetry equipment based on the IRIDIUM system and antenna (12) and GSM networks to determine the location of the GPMTC at any time, with an interface for geographical data transfer, including actual and measured speed and direction.
