Welcome to Gasconsult LNG

Gasconsult Limited is an independent LNG liquefaction technology licensor that co-operates with owners of gas reserves, project developers, OEMs and E&C companies world-wide.

Gasconsult’s patented ZR-LNG (Zero-Refrigerant) process is highly differentiated. It combines simplicity with an energy efficiency comparable to modern base-load plants; around 300kWh/tonne in temperate climates. It uses no external refrigerants, using the natural gas feed as the refrigerant medium in an optimised system of expanders. The simple design, a 1 million tonne/year train typically contains only 11 equipment items; and elimination of external refrigeration systems reduces capital cost, the project implementation schedule and footprint of the plant. The process is suitable for use in the capacity range 0.05 – 2.5 million tonnes/year per train.

ZR-LNG has been progressively developed. Audits by an oil major and 3 engineering companies have validated the basic design. Leading OEMs have confirmed machine configurations and that all equipment operates in a window of proven operating experience. Design developments include advantageous proprietary schemes for processing low pressure feed gases and for integrated C5+ removal.
