membrane gas separationflow configurationgas permeabilityAn internally staged hollow fiber polysulfone membrane is used to generate a permeate stream enriched in CH4H10 from a feed mixture of CH4, C2H6, C4H10, CO2 and N2. Experimental measurements are made as a function of the feed pressure and ...
interfaces, transport within the gas diffusion electrode, and electrical current drained from the fuel cell. The relevant membrane properties can then be sufficiently described by: (i) the relation between water concentration and water activity (hydration isotherms and swelling in liquid water); ...
The purge bin off-gas is first compressed from atmospheric pressure to around 22 bar. The compressed gas is then cooled and passed through a gas/liquid separator. The gas leaving the separator enters the membrane unit, where hydrocarbons permeate to the low pressure side more readily than nitrog...
ing the hydrocarbon vapor stream to membrane separation to provide a hydrocarbon product stream and a permeate stream, compressing the permeate stream and recycling the compressed permeate stream to the inlet of the primary reflux drum thereby providing a CO2 liquid product and a hydrocarbon gas ...

Membrane gas separation applications in natural gas processing Colin A. Scholes, ... Sandra E. Kentish, in Fuel, 2012 3 C3+ hydrocarbon removal Raw natural gas is often saturated with propane, butane and higher hydrocarbons, which need to be separated before the gas can be piped. This is ...
Also, oil pollutants can form a mucous membrane on the root system of plants, which impede respiration and absorption of nutrients. Nutrient deprivation results in a decrease in metabolic capacity directly affecting chlorophyll synthesis and appearance of deformed or necrotic vegetative organs (Rusin et...
3. Deep-seated faults in the sediment enabled methane-rich fluids to be channeled towards the seafloor, producing cracks in the lithified host sediment that enable the formation of gas hydrate (Fig. 3A)21. These fluids circulate in the subsurface and mix with seawater providing sulfate for SD...
A research team from the Georgia Institute of Technology and ExxonMobil has demonstrated a new carbon-based molecular sieve membrane that could dramatically reduce the energy required to separate a class of hydrocarbon molecules known as alkyl aromatics.
In at least one embodiment, at least a portion of the treated gas stream is diverted to a membrane purification unit for CO2 removal. In at least one embodiment, one or more of the first or second adsorbent bed comprises an amorphous silica adsorbent and/or an amorphous silica-alumina adsorb...
