Carbon-emission-free marine oil gas energy production method and device

Abstract

The invention relates to a carbon-emission-free marine oil gas energy production method and device. The method includes the steps that marine oil gas is produced, flue gas produced by the marine oil gas energy production device is subjected to seawater washing desulfurization, and the carbon-containing nitrogen-containing flue gas is re-injected into seabed oil and gas field. The device comprises a marine oil gas exploitation facility, a seawater washing desulfurization device, a carbon-containing nitrogen-containing flue gas pressurizing and reinjection device, a marine fuel power plant erected beside the marine oil gas exploitation facility and used for supplying power to a power grid, and an oil gas processing plant. The method and device have the advantages that carbon dioxide generated in the marine oil gas energy production process is economically and safely stored, and the oil gas recovery rate, namely the ratio of the produced quantity of oil gas to the reserve of the marine oil and gas field, is increased. A feasible approach for fossil fuel carbon-emission-free clean utilization is provided, and a brand new economic and efficient solution is added for achieving the 2-DEG C climate goal (2DS) of the international energy agency (IEA) and the all-process technology.

Description

technical field [0001] The invention relates to a production method and equipment for carbon-free marine oil and gas energy, which is applicable to the energy production of marine oil and gas exploitation, power generation and electric energy conversion and transportation for carbon dioxide capture and storage (CCS) in the whole process, and belongs to the technical field of clean energy and marine engineering . Background technique [0002] Carbon capture and storage (CCS) technology to reduce greenhouse gas emissions from fossil fuels is the main measure to achieve the International Energy Agency's (IEA) 2°C climate goal (2DS) (the global long-term average temperature rise is limited to below 2°C), but The long-term problems of capture, transportation and storage and the overall high cost and additional carbon emissions, as well as the long-term safety problems of large-scale underground storage, limit the promotion and implementation of the whole process CCS technology....

AI Technical Summary

Problems solved by technology

However, the plan to use carbon dioxide from human emission sources to increase oil and gas production and store it has been difficult, mainly because of the high cost of carbon capture, transportation and storage of the flue gas produced by fossil fuels on the one hand , on the other hand, there is a destructive sulfur corrosion problem, and the CO 2 -Reports that EOR was terminated after ten years due to explosion caused by corrosion leakage and the oil well was scrapped

From the above, it can be seen that Image 6 , Figure 7 As shown in the existing fossil fuel energy production method, the carbon emission source is far away from the mining source, and it is also far away from the safe and economical storage sink, thus increasing the difficulty of the whole process of carbon capture, transportation and storage, including increasing the difficulty of preventing sulfur corrosion
