Gasconsult, the UK based supplier of methane cycle liquefaction technology has awarded a contract to LNG engineer CB&I for development of its ZR-LNG liquefaction process.
The work will comprise design development of the ZR-LNG process for a gas turbine driven FLNG application based on multiple single train modules of nominal 1.5 million and 1.0 million tonnes/y capacity.
The work is being co-funded under the British Government’s Innovate UK scheme and the work will be performed from CB&I’s Paddington, UK offices, Gasconsult said on Monday.
To comply with the objectives of the Innovate UK grant regarding technology application in developing countries, the work will also include a pre-feasibility study of a land-based coal seam gas LNG plant in Botswana. The Botswana work will be performed by OTC, a Johannesburg based engineering company.
The ZR-LNG process requires no external refrigerants, using the methane feedgas as the refrigerant medium and eliminating refrigerant extraction or storage equipment. Refrigerant supply logistics to remote locations are eliminated and there are no refrigerant make-up costs. The absence of a liquid hydrocarbon refrigerant inventory reduces fire and blast risk, enhancing safety, the company said.
The design concept has already been validated by BP and several large E&C companies active in LNG, Gasconsult said.
