Reply #3: Exxon Mobil to build plant to remove CO2 from natural gas

[Fledermaus]

If it is feasible, it would be better to build natural gas power plants next to gas fields and put the CO2 back.

ExxonMobil Corp. said it is investing $100 million to develop a natural gas treating technology that could make carbon capture and storage more affordable and significantly reduce greenhouse gas emissions.

Using the its CFZ process, the carbon dioxide and other components are discharged as a high-pressure liquid stream for injection into underground storage or for use in reservoir management to improve oil recovery. Besides reducing the cost of separation, transportation and reinjection, the CFZ process can eliminate the use of solvents, sulfur plants and carbon dioxide venting in processing of the natural gas, Exxon Mobil said.

The new demonstration plant will process about 14 million cubic feet of gas per day for injection and test a wide range of gas compositions to evaluate the extent of its applicability to the world's undeveloped gas resources.

Construction will begin this summer for operational startup in late 2009. Testing is expected to occur over one to two years.
