The method of claim 1, wherein the compressive medium includes at least one of an inert medium, the material fed to the first unit, and the processed material exiting the first unit. 7. The method of claim 1, further comprising the steps of: feeding a composition to a second unit; processing, within the second unit, at least a portion of the composition;monitoring at least one of internal pressure, temperature, and concentration at least one of within the second unit or downstream from the second unit; andpressurizing the containment device, at least partially containing the second unit therein, with the compressive medium to maintain the pressure differential between the internal pressure within the containment device and an internal pressure within the second unit such that the internal pressure within the containment device is greater than the internal pressure within the second unit. 8. The method of claim 7, wherein the second unit includes microchannels through which the composition may flow therethrough. 9. The method of claim 1, wherein: the material comprises steam and methane;the microchannels of the first unit comprise a microchannel reactor; andprocessing of the material includes reacting the steam and the methane as part of a steam reformation reaction. 10. The method of claim 9, wherein: the compressive medium includes water; andat least a portion of the water comprises steam that is conveyed to the microchannel reactor. 11. The method of claim 9, wherein the containment device is pressurized prior to feeding the material to the microchannel reactor. 12. The method of claim 1, wherein: the material comprises hydrogen and carbon monoxide;the microchannels of the first unit comprise a microchannel reactor; andprocessing of the material includes reacting the hydrogen and carbon monoxide as part of a Fischer-Tropsch reaction. 13. The method of claim 12, wherein monitoring step includes monitoring a concentration of hydrocarbon product resulting from the Fischer-Tropsch reaction downstream from the microchannel reactor. 14. The method of claim 12, wherein: the compressive medium includes water; andat least a portion of the water comprises steam that is conveyed outside the containment device. 15. The method of claim 12, wherein the containment device is pressurized prior to feeding the material to the microchannel reactor. 16. A method of starting up one or more units, the method comprising the steps of: starting up a first unit including microchannels therein by initially feeding a material to the first unit and through the microchannels;processing, within the first unit, at least a portion of the material;monitoring at least one of internal pressure, temperature, and concentration at least one of within the first unit or downstream from the first unit; andpressurizing a containment device, partially containing the first unit therein, with a compressive medium to maintain a pressure differential between an internal pressure within the containment device and an internal pressure within the first unit such that the internal pressure within the containment device is greater than the internal pressure within the first unit;wherein the compressive medium includes water; and,wherein at least a portion of the water comprises steam that is conveyed to the microchannel reactor.
