    LNG Loading Skid

    The LNG loading skid is an integrated solution for the LNG tank trailer loading & unloading . It composed of liquid pipe, vapor pipe, venting pipe, circle cooling pipe, liquid collecting pipe, instrument air pipe and LNG loading arm. All the pipe is controlled by the valves (manual or automatic valve is depending on the site condition). The LNG loading & unloading job could be easily operated.
    The LNG loading skid integrated lots of detect & control meters, including the flow meter, pressure transmitter, temperature transmitter, static-proof detection device, ESD Switch, etc. The controller can detect the pipeline status by the meters and make action according to the requirement. A safety and high effective loading job could be performed. 

    Technical Specifications

    1) Explosion-proof box, safety design. 
    2) Large screen display showing the complete process flow.
    3) 16 magnetic-control keyboard, complete insulated from inner parts.
    4) RS485 interface communicable with MODBUS RTU protocol.
    5) Manual mode and IC Card mode convertible for monitoring.
    6) Controller connected with IC Card reader, easy for connecting confirmation.
    7) Detail operation guide during the process.
    8) PLC applied for the terminal equipment monitoring.
    9) Flow rate adjustable by the control valve.
    10) Controllable solenoid valves on the pipe of liquid, vapor, liquid collection and nitrogen. The valves could be controlled automatically during the loading process.
    11) Maximum 3 signals of ESD switch could be connected with link-lock alarm.
    12) The signal of static detection switch could be connected with link-lock alarm.
    13) The signal of reset switch of two loading arms could be connected with link-lock alarm.
    14) Maximum 3 temperature signals and 3 pressure signals could be displayed with link-lock alarm.
    15) Flow level bar displayed for easy monitoring.

    Metering Loading Skid System

    LNG Metering Loading Skid System is an integrated solution for the LNG tank trailer loading & unloading. It integrated within a frame with size of 2.5m x 2.5m x 5.5m. It composed of liquid pipe, vapor pipe, venting pipe, circle cooling pipe, liquid collecting pipe, instrument air pipe and LNG loading arm. The flow meters, pressure valves and process control valves are integrated in the skid. Especially the gasification device for the unloading work, the device collects the liquid LNG from liquid pipe then gasify it, the gasified high pressure gas offer a continuous pressure for the unloading system. All the meters are controlled by PLC system. The CPU will execute the unloading work according the logic sequence.
    The complete skid is a compact structure, clear logic, safe design with small space requirement. It will be the new direction of the LNG loading & unloading work.

    PLC Logic Control Stem for the entire handing process control, monitoring, pre-test to reconcile

    Main functions 

    1) Monitoring the LNG loading metering
    2) Flow rate control
    3) Pressure and temperature test and control
    4) Dynamic display the loading process, parameters and facilities’ status.
    5) Long range control the valves, pump etc. setting and modify the parameters on line.
    6) Alarm the abnormal conditions for record.
    7) Connect with the owner’s existed system by communication protocol. Coordinate the complete work. 

    Main Features

    1) Combined with aero-space cryogenic technologies.
    2) Loading & unloading both available. Two sides both available.
    3) Combined display for the PG, TIT and PIT.
    4) The swivel joint applied the dynamic seal technology which is applied on the liquid hydrogen. Avoid deformation or damage to the seal surface.
    5) Key components are all world top brand.
