Embodiment 1

[0028] Example 1 Comprehensive Energy Utilization System for Natural Gas Storage and Peak Shaving

[0029] Such as figure 1 As shown in , a comprehensive energy utilization system for natural gas storage and peak regulation, including a crude oil depot 1, a natural gas refining unit, a natural gas storage depot 14 and a natural gas utilization unit connected by pipelines in sequence; the natural gas utilization unit includes chemical production equipment 13. The urban natural gas pipeline network 20 and the power conversion unit, the pipeline between the natural gas storage 14 and the chemical production equipment 13 is provided with a second natural gas gate station 12, and the natural gas storage 14 and the urban natural gas pipeline network 20 are bidirectional Pipeline connection, the pipeline between the natural gas storage 14 and the urban natural gas pipeline network 20 is provided with a fifth natural gas gate station 19;

[0030] The natural gas refining unit include...

Embodiment 2

[0031] Embodiment 2 Natural gas storage peak shaving method

[0032] Step 1. The crude oil in the crude oil depot 1 is transported to the distillation refinery equipment 2, the cracking refinery equipment 3, and the reforming refinery equipment 4 respectively for refining, and the refined products are separated in the first oil-gas multi-stage separation equipment 5, Then the separated methane is transported to the natural gas storage 14 after being pressure-regulated by the third natural gas gate station 15, and part of the unseparated organic products are transported to the refined oil and gas storage facility 7 for storage;

[0033] Step 2. The organic matter in the refined oil and gas storage facility 7 is sequentially transported to the organic matter cracking equipment 8 and the second oil and gas multi-stage separation equipment 9 for cracking, and the methane generated by the separation is pressure-regulated by the first natural gas gate station 11 and then transported ...

Description

technical field [0001] The invention relates to the field of natural gas energy utilization, in particular to a comprehensive energy utilization system for natural gas storage and peak regulation and a gas storage peak regulation method. Background technique [0002] Natural gas has become one of the main energy sources in my country, and the security, stability and continuity of its supply are related to the country's energy security. Due to the large changes in the external environment of the economy and society, the overall situation of China's oil and gas supply security is relatively uncertain at present and for a long period of time in the future. In response to the challenges of energy and the environment, resources and climate change, the Chinese government is studying and promoting the "revolution" in four aspects: energy consumption, energy supply, energy technology and energy system, and has proposed a diversified, clean and efficient energy development strategy ,...
