LCNG REFUELLING STATIONS
Customised LCNG infrastructure that converts stored LNG into high-pressure CNG for public or captive NGV refuelling. LAIMEX engineers, executes, commissions and supports the complete facility; we do not supply gas.
LCNG APPLICATIONS
Station capacity and configuration begin with vehicle demand, LNG logistics, site constraints, required autonomy and the customer’s operating model—not a preselected equipment package.
High-throughput LCNG stations developed for safe, convenient public vehicle refuelling where LNG logistics provide the gas source.
Purpose-built LCNG infrastructure for haulage, bus and commercial fleets, matched to route schedules, refuelling windows and vehicle demand.
Combined infrastructure that can support industrial gas delivery and vehicle refuelling from one LNG receiving and storage system where technically appropriate.
TYPICAL PROCESS PATH
The final process design, set points and safeguards are developed from project-specific flow, pressure, ambient, logistics and applicable code requirements.
Maintains the required LNG-tank operating pressure and supports stable liquid delivery to the high-pressure pump.
Warms boil-off gas for controlled pressure management and practical BOG utilisation within the approved process scheme.
Safely warms cold emergency or vented cryogenic streams before discharge through the designed vent system.
EQUIPMENT & SYSTEMS
Equipment is selected and integrated around process duty, safety, maintainability, local operating conditions and lifecycle support.
Tanker connection, transfer hoses or arms, unloading skid, valves, check protection, ESD interfaces, earthing and controlled drainage.
Vacuum-insulated storage tank, level and pressure instrumentation, pressure protection, isolation, impounding and tank-management connections.
High-pressure LNG pumping system selected for station throughput, suction conditions, duty cycle, turndown, redundancy and maintainability.
High-pressure vaporisation capacity sized for flow, ambient conditions, icing behaviour, operating duration and required CNG delivery temperature.
Dedicated pressure-building, boil-off-gas and emergency ambient gas systems integrated for tank stability, utilisation and safe cryogenic handling.
High-pressure buffer or cascade storage, priority sequencing, isolation and pressure protection configured around simultaneous-fill demand.
NGV dispensers, hoses, breakaways, metering and refuelling controls selected for public or captive-fleet operation.
Integrated control, alarms, trends, interlocks, data logging, remote supervision and operational reporting across the complete facility.
Emergency shutdown stations, gas and flame detection, audible and visual alarms, shutdown cause-and-effect, fire protection and safe-state logic.
CAPACITY & CONFIGURATION
The storage tank, pump, vaporisation, buffer and dispensing systems must be evaluated together. A bottleneck in any one stage affects the complete refuelling duty.
Peak vehicles per hour, fleet size, daily throughput and the available refuelling window.
Delivery distance, tanker size, unloading frequency, usable tank volume and required operating reserve.
Inlet conditions, flow, discharge pressure, operating cycle, redundancy and maintenance strategy.
Ambient temperature, humidity, icing, defrost philosophy, turndown and continuous-duty requirements.
Buffer volume, bank sequencing, dispenser quantity and simultaneous vehicle-fill demand.
Power availability, backup philosophy, instrument air, data connectivity and future capacity growth.
SAFETY BY DESIGN
LCNG combines LNG handling with high-pressure CNG refuelling. LAIMEX develops the interfaces, safeguards, procedures and competency needed for the facility to reach and maintain a safe operating state.
LAIMEX DELIVERY SCOPE
Our principal role is engineering and project lifecycle support. Equipment and spares are incorporated where required to complete or sustain the engineered solution.
Demand assessment, LNG logistics, site survey, concept selection, preliminary sizing and commercial-technical definition.
Process design, PFD/P&ID, hydraulic studies, equipment sizing, layout, civil, mechanical, electrical, instrumentation and safety integration.
Procurement coordination, infrastructure development, installation, interface management, quality control and project documentation.
Inspection, leak and pressure testing, loop checks, interlock and cause-and-effect testing, start-up and performance verification.
Operations, preventive maintenance, troubleshooting, optimisation, spare planning and competent technical manpower.
Operator and maintenance competency, SOPs, LNG awareness, emergency response and practical station-readiness support.
