Appl. No.:

12/282410

Inventors:

Michael F. Tschantz - Lexington VA, US

Assignee:

MeadWestvaco Corporation - Glen Allen VA

International Classification:

B65B 31/02
B01D 27/10
B67D 5/63

US Classification:

141 45, 96108, 141 82

Abstract:

The present invention relates to a vapor recovery system for gas station that is capable of controlling vapor emission to less than 0.38 lbs/1000 gallons fuel dispensed. The system may include at least one canister containing adsorbents such as activated carbon, zeolite, activated alumina, silica, and other adsorbents for passive removal of hydrocarbon vapors in venting air. Additionally, the system may include a means to enhance vapor-liquid equilibrium in the ullage of the fuel tank and accordingly minimize vapor emission level.

Assignee:

MEADWESTVACO CORPORATION - Richmond VA

International Classification:

B01D 53/02

US Classification:

95148, 96130

Abstract:

A method for reducing hydrocarbon emissions from automotive evaporative emissions control systems comprising steps of: contacting a vented fuel vapor stream from a fuel tank () with a first passive purge canister bed (), the passive purge canister bed comprising a vapor adsorbent material and including a passive purge vapor inlet and a passive purge vapor outlet for vapor stream flow, -contacting a vapor stream from the passive purge vapor outlet with an active purge canister bed, the active purge canister bed () comprising a vapor adsorbent material; contacting the active purge canister bed with mechanically convected purge air, wherein the mechanically convected purge air is prevented from flowing through the passive purge canister bed; and contacting the passive purge canister bed with fresh purge air drawn passively by the fuel tank through the passive purge vapor outlet without first contacting said active purge canister bed.

US Patent:

Filed:

Jul 15, 2003

Appl. No.:

10/621946

Inventors:

Michael Tschantz - Lexington VA, US

International Classification:

F02M033/04

US Classification:

123/518000

Abstract:

The subject matter of the invention described and claimed herein is disclosed as a vapor-containing element for adding to the ductwork, or the inside walls of the AIS ductwork, which element preferably is shaped to conform to the shape of said ductwork, with the material forming the walls of the element. The open inside of the cylindrical component would allow air to pass through the element unobstructed, with little pressure drop.
