A detailed research study has been completed on existing work specific to micro-scale (less than 275 tones per day or 5 million GJ per annum) liquefied natural gas (LNG) production facilities. Results were analysed, compared and summarised to serve as initial design conditions for proposed process designs.

Direct DME Synthesis From Natural Gas
Dimethyl ether (DME) has been identified as an attractive fuel alternative and has seen an exponential increase in demand in the Asia Pacific. Dimethyl ether (DME) is a non-petroleum based transportation fuel, to act as a clean replacement for diesel fuel. Forecasts predict that the DME market will increase rapidly in the rest of the world.

Air Separation of Cryogenic Gases
An Air Separation Unit (ASU), is a type of technology that separates air into its main constituents. The most abundant components are Nitrogen, followed by oxygen and then argon, as well as other inert gases in small amounts.

Continuous Carbon Capture Process using Stirling Coolers
This article documents the current hypothesis for developing and testing a continuous Carbon Dioxide capture system using Stirling Coolers as the driving force.

Process Technologies for Helium Recovery from Natural Gas: A Review
This article reviews conventional processes used for recovery of helium from natural gas and examines the potential of emerging technologies for more efficient helium production processes, with main focus on Southern Africa’s new helium rich gas reserves.
