Mid & SmallScale LNG

Worleyis expanding its role in mid and small scale LNG plants by facilitatingthe development of these smaller scale LNG plants.
Mid scale LNGplants are smaller than base load plants, with capacities ranging from0.5 to 2 MTPA. These plants are targeted towards monetizing smallerstranded gas fields, debottlenecking base load facilities and as amethod to convert waste gas, which would otherwise be flared, into avaluable product stream for existing oil production facilities. Withoutthe economies of scale enjoyed by large base load facilities these midscale plants have to employ simple, robust, liquefaction cycles whilststill maintaining high thermal efficiencies available via the use ofaeroderivative gas turbine drivers. Worley has experience indesigning these plants for both onshore and offshore floatingapplications as well as in the liquefaction of extended end flash gasto debottleneck base load LNG plants.
Small scale LNG plants,sometimes called peak-shaving plants, are much smaller than base loadplants. Such plants are suitable for supporting niche LNG markets whichare becoming increasingly important, especially for remote powergeneration.and in the transportation fuels sector as a substitute forgasoline or diesel.
Small scale LNG plants can be developed tooccupy small amounts of space which makes them adaptable for locationsclose to niche markets. Seasonal demands can require gas to beliquefied and stored for the peak usage season and small LNG plants canprovide a buffer to meet this additional demand. We are also ideallyplaced to provide study phase work and full design, procurement andconstruction management for both micro and mini LNG facilities for ourcustomers.


Project:PTTEPS LNG Plant
Customer: Thailand PTTEPS

Thailand
PTTEPSproposed to install an LNG facility for the S1 Production Station inLankrabrue,  Kampangphet province, Thailand. WorleySelectconducted the feasibility study for a small scale LNG plant to producevehicle transportation fuel. The project consisted of pre-treatment, liquefaction, storage and loading systems for roadtankers. Worley
evaluated various liquefaction technologiesfor plant sizes from 5 - 20 mmscfd of feed gas to determine the mostsuitable LNG process. The study provided cost estimates, equipmentlayouts, utility requirements, driver selection and thermal efficiencyestimates.

LNGModularization

Worleyspecializes in the evaluation, design and implementation of projectsrequiring pre-assembled modules for complex process facilities.
Modular solutions within the complex processing industry come intotheir own when specific project challenges arise, such as:
• Remote and hostile environments
• Minimizing disruption to ongoing plant operations
• Avoiding on-site labor shortage or industrial relations issues
•Improving cost and schedule, when compared to traditional “stick-build”methods by utilizing low cost specialist fabrication yards, such asthose found in South East Asia
Beginning with the design of thefirst pre-assembled modular facilities for the remote North Slope inAlaska, Worley has gained extensive world wide experience inmodularization. Worley has been involved in over 50 onshoreprojects in 30 countries that have required modular solutions includingthe design of more than 1,300 modules with a total weight of over435,000 tonnes. These modules have ranged in size from 5,000 tonnes tosmaller modules.
In parallel, the experience gained within theoffshore industry has enabled Worley to bring major innovationsto modularized construction. Whilst all offshore topside design isessentially modularized, it is in the area of the large floatovertopsides - weighing up to 22,000 tonnes in a single mega module - thatthe Worley reputation has excelled in recent years. The weightand space savings experience inherent in offshore modular design isdirectly relevant for use in an onshore LNG plant setting.
Thismodularization skill set was recently employed within the North WestShelf LNG Phase V expansion project and is being used extensively onthe Pluto LNG development.
