We claim: 1. A closure device for a tank assembly, the tank assembly including a tank wall defining an interior and an exterior, a liquid being containable in the interior, vapor being produceable from the liquid, the closure device comprising: a closure housing selectively connected to the tank assembly and defining a flow path between the interior and the exterior; adsorption media supported by the closure housing, a flow path being provided from the interior of the tank assembly, through the adsorption media and to the exterior of the tank assembly, vapor being routed along the flow path from the interior of the tank assembly and through the adsorption media, the adsorption media adsorbing the vapor; a media housing connectable to the closure housing and supporting the adsorption media; and a vapor/liquid separator connected to the media housing, the separator being operable to prevent liquid contained in the tank assembly from entering the media housing and contacting the adsorption media. 2. The device of claim 1, wherein the separator includes a valve operable between a closed position, in which liquid and vapor are not allowed to pass from the interior of the tank assembly into the media housing, and an open position, in which air from the exterior of the tank assembly is allowed to pass into the interior of the tank assembly. 3. The device of claim 1, wherein air from the exterior of the tank assembly is routed along the flow path from the exterior of the tank assembly, through the adsorption media and to the interior of the tank assembly to desorb from the adsorption media vapor adsorbed by the adsorption media. 4. The device of claim 1, wherein the tank wall defines an opening between the interior and the exterior, tank threads being defined proximate to the opening, and wherein the closure housing defines cap threads complementary to and engageable with the tank threads to connect the closure housing to the tank wall. 5. The device of claim 1, wherein the media housing is removably connectable to the closure housing. 6. A closure device for a tank assembly, the tank assembly including a tank wall defining an interior and an exterior, a liquid being containable in the interior, vapor being produceable from the liquid, the closure device comprising: a closure housing selectively connected to the tank assembly and defining a flow path between the interior and the exterior; adsorption media supported by the closure housing, a flow path being provided from the interior of the tank assembly, through the adsorption media and to the exterior of the tank assembly, vapor being routed along the flow path from the interior of the tank assembly and through the adsorption media, the adsorption media adsorbing the vapor; and a media housing connectable to the closure housing and supporting the adsorption media; wherein the media housing includes a side wall, and wherein the adsorption media is supported in the media housing with a gap between the adsorption media and the side wall, the flow path being from the interior of the tank, into the gap and through the adsorption media. 7. The device of claim 6, wherein the media housing includes a bottom wall, wherein the adsorption media is supported in the media housing with a gap between the adsorption media and the bottom wall, and wherein the device further comprises a seal positioned in the gap between the adsorption media and the bottom wall to prevent flow of vapor through the gap between the adsorption media and the bottom wall. 8. The device of claim 7, wherein the adsorption media defines a central opening, and wherein the bottom wall includes an upstanding portion extending into the central opening. 9. The device of claim 8, further comprising a separator member supported on the upstanding portion. 10. The device of claim 9, wherein the separator member includes a valve member preventing liquid and vapor in the interior of the tank assembly from entering the media housing and allowing air from the exterior of the tank assembly to pass from the central opening and into the interior of the tank assembly. 11. The device of claim 6, wherein the media housing includes a top wall connected to the side wall, wherein the adsorption media is supported in the media housing with a gap between the adsorption media and the top wall, and wherein the device further comprises a seal positioned in the gap between the adsorption media and the top wall to prevent flow of vapor through the gap between the adsorption media and the top wall. 12. The device of claim 11, wherein the top wall defines an aperture, the flow path being defined from the interior of the tank assembly, through a space between an outer surface of the side wall and the closure housing, through a space between an outer surface of the top wall and the closure housing, into the media housing through the aperture, into the gap between the adsorption media and the side wall, through the adsorption media and to the exterior of the tank assembly. 13. The device of claim 12, wherein the space between the outer surface of the side wall and the closure housing, the space between the outer surface of the top wall and the closure housing and the aperture in the top wall cooperate to define a tortuous flow path from the interior of the tank assembly into the media housing. 14.
