CO2 Removal Membranes |
|
MTR’s membrane-based systems provide a simple, low-cost, compact solution for reducing CO2 content in natural gas. These novel membranes have a unique polymer chemistry that is far superior to conventional membranes in withstanding the various components in natural gas. These membranes are used to achieve pipeline CO2 specifications of 4 mol% or less, or for bulk CO2 removal. Due to the high fluxes of these membranes and efficient module packaging, using MTR’s membrane process minimizes required deck space and weight in offshore installations.
System Performance:
Feed Rate: < 1 MMscfd to > 300 MMscfd,
Feed CO2 Content: > 40 mol% to < 5 mol%,
Product CO2 Content: to < 2 mol%,
Hydrocarbon Recovery: > 95% +.

NitroSep system |
|
MTR’s membrane-based NitroSep system is an economical solution. This system produces pipeline-quality or pipeline-acceptable gas, along with nitrogen-rich fuel, from raw natural gas. The membranes are more permeable to methane, ethane, and other hydrocarbons than to nitrogen. Gas containing 8% to 12% nitrogen is compressed and passed across a first set of membrane modules. The permeate, which contains 6% nitrogen, is sent to the pipeline; the nitrogen-rich residue gas is passed to a second set of membrane modules. These modules produce a residue gas containing about 40% nitrogen and a nitrogen-depleted permeate containing 10% to 20% nitrogen. The residue gas is used as fuel; the permeate is mixed with the incoming feed gas for recovery.
System Performance:
Feed rate: Wide range up to 200+MMSCFD,
Feed N2 content: 4% to 50% (Bulk Reduction),
Target N2% or BTU value,
Hydrocarbon BTU recovery: >90%.
