AI Technical Summary

Benefits of technology

The invention aims to create a device that can produce carbon dioxide economically using low operating and capital costs.

Problems solved by technology

Since, however, the costs of transporting these, in particular gaseous, by-products and / or treatment thereof usually exceed the expected sales proceeds, the use of the by-products, in particular the fuel gases, or treatment thereof is usually dispensed with solely for economic reasons.

Embodiment Construction

[0040]FIG. 1 shows a device 1 for using carbon dioxide formed in the combustion of in particular a gaseous by-product of oil recovery. The device 1 comprises a treatment unit 3 having a burner 5 and a steam generator 7. In addition, the device 1 comprises a carbon dioxide separation device 9 that is flow-connected to the treatment unit 3. In the separation device 9, carbon dioxide that is formed in the context of the combustion is separated off from the exhaust gas by means of a scrubbing medium. For this purpose, the separation device 9 comprises an absorber 11 and a desorber 13 that is flow-connected thereto.

[0041]The device 1 permits an on-site production and subsequent utilization of carbon dioxide in tertiary oil recovery. In tertiary oil recovery, the oil that is to be recovered is produced by injecting carbon dioxide into corresponding wells of a recovery site 15. In addition to the oil, in this case, fuel gases that are no longer technically utilizable, that is to say gaseou...

Abstract

A device for using carbon dioxide originating from the combustion of a byproduct has a preparing unit which is connected to a delivery station for fossil fuels, which has a burner for combusting a byproduct that is released when the fuel is delivered, and an exhaust gas line that is connected to the burner. A depositing device is fluidically connected to the preparing unit via the exhaust gas line, for carbon dioxide. The depositing device is fluidically connected to the delivery station to redeliver fuel via a supply line for carbon dioxide. Such a device allows the production and the subsequent controlled use of carbon dioxide from previously unused byproducts in the production of crude oil. A corresponding method by which carbon dioxide originating from the combustion of a byproduct is used in a controlled manner, in particular as part of a fossil fuel extraction process.

Description

CROSS REFERENCE TO RELATED APPLICATIONS[0001]This application is the US National Stage of International Application No. PCT / EP2015 / 054249 filed Mar. 2, 2015, and claims the benefit thereof. The International Application claims the benefit of German Application No. DE 102014204646.7 filed Mar. 13, 2014. All of the applications are incorporated by reference herein in their entirety.FIELD OF INVENTION[0002]The invention relates to a device for using carbon dioxide that is formed in the combustion of particularly a gaseous by-product, in particular in the context of producing a fossil fuel. In addition, the invention relates to a method for using carbon dioxide formed in the combustion of particularly a gaseous by-product.BACKGROUND OF INVENTION[0003]The deposits of fossil fuels stored in the ground such as, for example, natural gas, or in particular oil, which are obtainable economically with current technology serve as energy reserves in order to cover the constantly increasing energy...
