LNG Plant Design & Installation
LNG Satellite Plants
LNG Satellite Plants are facilities where LNG is taken from large LNG receiver or import stations by tankers and trains for storage and transfer to the network when necessary. LNG satellite stations can be built to meet usage needs of various sizes. City gate stations can feed the needs of a small city or town, while smaller satellite stations can meet the energy needs of a factory.
LNG City Gate Plants
LNG City Gate Plants are used for remote small towns or cities which do not have access to natural gas pipeline grids.
Parts of Satellite Stations
LNG Satellite Stations mainly contain storage tanks and atmospheric evaporators along with odorizing systems, interconnection pipelines, valves, and safety systems.
Storage Tanks
Storage tanks used for LNG storage are cylindrical, perlite and vacuum insulated tanks can be vertical or horizontal depending on the needs. LNG tanks and valves or other equipment on the tank also must have cryogenic properties. Before LNG is loaded into the tanks, the temperature of the inner tank is cooled to -190°C with nitrogen gas and LNG at -162°C is filled. During this transfer, the pump is not used, and the transfer is realized with the pressure difference by reducing the pressure of the inner tank and increasing the pressure of the transfer tanker.
Atmospheric Evaporators
Atmospheric Evaporators are used to convert LNG from liquid phase to gas phase. Evaporators make the LNG gasified using ambient temperature and ready to be consumed. It has high heat exchange capabilities thanks to its large heat transfer surfaces. They are made entirely of aluminum. Since they have no moving parts, they do not require maintenance.
Odorizing Systems
Natural gas is an odorless fuel. However, scenting is done against leaks at the points of use. Due to the very low temperatures in the LNG tank, no odorizing chemicals can be used. For this reason, after LNG is turned from liquid to gas in the evaporator, it is scented with a special chemical in the odoring system.
Safety Systems
It consists of separate systems such as gas leak detection systems, gas temperature monitoring and control system, earthquake monitoring system, LNG facility main control panel and parallel warning panel, boiler room gas leakage alarm system and pressure reduction stations.
