| 英文摘要: | Air Products has retrofit each of its two steam methane reformers (SMRs) located within the existing Valero Energy refinery at Port Arthur, Texas, with vacuum swing adsorption (VSA) systems to separate the CO2 from the process gas stream. The capture facilities also include compression and dehydration equipment as well as a new cogeneration unit to supply electricity and steam to the SMR plants and VSA systems.
The SMRs produce hydrogen, which is widely used in petroleum refining to remove impurities such as sulphur. The hydrogen produced is used by Valero at its refinery and by other West Gulf Coast customers supplied via pipeline. The SMRs are owned and operated by Air Products. Valero Energy is providing additional land and rights-of-way required for the project, as well as utilities support.
Each VSA unit is designed to remove more than 90 per cent of the CO2 contained in the reformer pressure swing adsorption unit feed gas that it would process. The carbon capture processes concentrate the initial gas stream (containing 10-20 per cent CO2) to greater than 97 per cent CO2 purity.
The first SMR began capturing CO2 in December 2012, the second in March 2013. When operating at full capacity both plants capture approximately 1 Mtpa of CO2.
The captured CO2 is transported within Jefferson County through a 21 km / 13 mile, 8-inch diameter pipeline connector where it will tie into Denbury’s existing Green Pipeline. The CO2 will then be transported approximately 137 km / 85 miles via the (24-inch diameter) Green Pipeline to the Hastings oil field in Brazoria County, Texas (where Denbury owns and operates an interest in the field).
The Hastings oil field was discovered in 1934 and has produced around 600 million barrels over its life (from both West Hastings and East Hastings). Primary production peaked in the mid-1970s and fell to around 1,000 barrels per day in 2009 / 2010. Denbury bought a majority interest in the field in early 2009. CO2 injection in the West Hastings Unit began in December 2010 (upon completion of the construction of the Green Pipeline and using naturally occurring CO2 sourced from Jackson Dome, Mississippi). Oil production from CO2-EOR operations began in January 2012.
Injection of anthropogenic CO2 from the Air Products SMR EOR Project began in early 2013. Oil reserves recovery is from the Frio sandstone formation. The CO2 injection is in a moderate depth (1,700 metres / 5,700 feet) formation with light, sweet crude oil with a gravity of approximately 31 degrees.
To supplement Denbury’s ongoing commercial monitoring activities, Denbury and the Texas Bureau of Economic Geology, plan to jointly implement a research monitoring, verification and accounting (MVA) program to study the movement and sequestration of CO2 through existing EOR operations. The proposed research MVA will be confined to a portion of the West Hastings field and will involve the close monitoring of around 1 million tonnes of CO2injected into the Frio sandstone formation. The program aims to provide a high level of confidence that CO2 injected during existing EOR operations will remain permanently sequestered. |
