Engineering Services / Field Services

Air Products offers a wide range of engineering services which form the basis for overall support of an LNG facility. (1)During the design of the LNG plant, Air Products provides the process design for the liquefaction facility, the detailed design of the plant area surrounding the MCR® Cryogenic Heat Exchanger, and review and consultation for the plant owner or general contractor. Air Products also provides advisory services to the owner and engineering contractor during exchanger shipment, and field construction activities and at the time of plant commissioning and start-up. Air Products provides advisory services during transportation, field installation, commissioning, training and start-up of the liquefaction system.(2) after start-up, Air Products offers field services that include technical assistance with diagnosing plant operating problems and the maintenance and repair of the main cryogenic heat exchanger. Diagnostic services can range from assisting with the collection and evaluation of performance test results to identify plant bottlenecks. Air Products' field servicing capability is a valuable extension to its equipment and helps to ensure long-term efficient and reliable operation of the plant.
