Frequently Asked Questions

We assess normal and peak gas demand, operating profile, available gas source, pipeline proximity, required pressure, site location, logistics, utilities, land, expansion plans, reliability and overall project economics. Proper design and engineering should establish the project duty before equipment is selected.

Useful information includes project location and application, average and peak hourly gas demand, daily consumption, operating pressure and hours, existing fuel consumption where relevant, gas or LNG supply options, site constraints, utilities and expected expansion.

Yes. Early design and engineering review can check the process concept, capacity, equipment sizing, interfaces, controls, safety philosophy, vendor proposals, project risks and missing engineering information before major procurement commitments.

A CNG mother station compresses gas from a suitable source for high-pressure storage, transport or refuelling. An NGV daughter/refuelling station receives transported CNG for vehicle dispensing, with its own dispensing and control arrangements. An industrial CNG downloading station receives transported CNG and reduces or conditions it for an industrial consumer’s pressure and operating requirements.

Design and engineering should assess normal and peak gas demand, inlet pressure and temperature, discharge pressure, operating hours, demand profile, redundancy, turndown, gas composition and future capacity. The complete compression, storage and loading or refuelling duty matters more than a compressor’s nameplate flow alone.

Consider normal and peak demand, daily consumption, delivery distance and turnaround, cylinder water volume, filling pressure, usable pressure range, residual gas, temperature and deliveries needed for continuity of supply.

It can be possible, but design and engineering must cover the combined compressor duty, storage philosophy, priority logic, peak gas flow, pressure requirements, metering, controls and safety arrangements.

An LCNG system stores LNG as a cryogenic liquid, raises its pressure with a high-pressure cryogenic pump and vaporizes it to produce high-pressure natural gas for CNG storage or vehicle dispensing.

LCNG may suit a site where LNG logistics are practical and pipeline gas is unavailable or unsuitable, or liquid transport offers an advantage. Design and engineering should compare normal and peak demand, required pressure, operating profile, LNG logistics, site constraints and project economics before selecting the pathway.

A system may include LNG storage and unloading, pressure-building arrangements, high-pressure cryogenic pumps, vaporizers, pressure control, instrumentation, PLC/SCADA, safety systems, CNG storage and dispensing where required. Configuration and capacity depend on normal and peak demand and the engineered project duty.

Design and engineering should account for normal and peak consumption, operating hours, delivery frequency and logistics, reserve or autonomy, usable tank volume, operating limits, expected boil-off and future demand growth.

Design and engineering should consider normal and peak gas flow, LNG conditions, required outlet conditions, operating duration and redundancy. For ambient-air vaporizers, ambient temperature, humidity and icing are particularly important; other technologies must be assessed against their respective heat source, duty and operating conditions. Nominal nameplate capacity alone is insufficient for selection.

LNG pressure management should account for normal operating demand and low-demand or idle periods, pressure-building needs, normal vapor/BOG handling and independent overpressure protection. The appropriate arrangements depend on tank design, operating philosophy and applicable project requirements; no one vapor handling route suits every installation.

Normal and peak gas flow, inlet pressure range, outlet pressure, gas conditions, operating profile, allowable pressure loss, metering range, downstream demand, redundancy and expansion determine the duty. Design and engineering should also address regulator sizing, reduction stages, filtration, protection, piping velocity, instrumentation and controls rather than relying on a nominal SCMH rating alone.

Staging a large pressure drop may assist control stability, regulator operation and thermal management. The number and arrangement of stages should be engineered for the minimum-to-peak flow operating envelope, inlet and outlet pressure ranges, regulator characteristics, gas temperature effects and downstream requirements. Staging does not replace proper thermal assessment or gas heating where required.

Depending on duty, this may include filtration, isolation, regulation, slam-shut protection, relief, metering, pressure and temperature instruments, ESD, venting and monitoring. The final protection philosophy must follow the project design and applicable requirements.

Depending on the application, infrastructure may include cryogenic storage, transfer or high-pressure pumping, vaporization, pressure regulation, distribution, piping, instrumentation, control and safety systems, plus cylinder filling where required.

Design and engineering should consider normal and peak consumption, delivery frequency, reserve, operating pressure, usable tank volume, evaporation or boil-off, site constraints and future expansion.

Normal and peak gas flow, ambient temperature and humidity, operating duration, continuous or intermittent duty, icing, outlet conditions and redundancy all matter. Selecting only by nominal flow can leave the system short under actual site conditions.

Equipment must match the actual process duty and work within an engineered system. Design establishes normal and peak capacity, pressures, configuration, piping and instrumentation, controls and interlocks, safety and protection, utilities, interfaces, maintainability, lifecycle needs and future expansion before major purchases.

Yes. LAIMEX can support concept development, design and engineering, specification, technical evaluation and project advisory independently of equipment supply, according to the agreed scope.

Yes. Equipment and package sourcing can form part of an engineering-led scope. Selection should consider technical duty, normal and peak conditions, compatibility, reliability, maintainability, lifecycle support, spares and project economics.

LAIMEX follows a multi-OEM approach. Options can be evaluated against the client’s technical, operating and commercial requirements rather than automatically selecting a single manufacturer.

Yes. Evaluation can consider capacity, normal and peak duty, operating envelope, specification compliance, maintainability, controls, documentation, local support, spare-parts availability and lifecycle suitability.

Depending on scope, commissioning may cover mechanical-completion review, instrumentation checks, calibration verification, control and interlock testing, leak and pressure-test record review, functional testing, startup, performance verification and operator training.

This may be possible, subject to documentation, defined responsibilities, access to technical information and any OEM-specific commissioning requirements.

Depending on the agreed scope, support may include procedures, preventive-maintenance planning, troubleshooting, performance review, instrumentation and controls, operator training, maintenance coordination and lifecycle improvement.

Yes. Spares support can address commissioning, preventive and corrective maintenance and continued operation, with attention to compatibility, equipment duty and OEM requirements.

It is useful before financing, acquisition, major equipment orders, construction or project takeover. A review can identify missing engineering, design inconsistencies, equipment risks and documentation gaps affecting cost, safety, performance or completion.

Depending on project maturity: process flow diagrams, P&IDs, layouts, datasheets, specifications, vendor proposals, control philosophy, electrical documents, safety studies, civil information, commissioning records and applicable project requirements.

LAIMEX can support early concept and technical evaluation through design and engineering, equipment selection, execution, commissioning, O&M and lifecycle support, according to the client’s requirements and agreed scope.

Use the Project Enquiry page. Share the location, application, normal and peak demand or capacity, supply source, required pressure, project stage and available technical documents so LAIMEX can determine the next technical step.
