Abstract

The invention relates to the technical field of natural gas pressure regulation, in particular to a natural gas residual pressure cold energy utilization system. A first pressure regulating device anda first seawater desalting device are involved in the application, wherein the first pressure regulating device comprises a first pressure stabilizing valve, a first precooler, a temperature regulator, a second pressure stabilizing valve, a first expander, a first generator and a first heat exchanger; and the first seawater desalting device comprises a filter, a first crystallizer and a first icestorage device. According to the natural gas residual pressure cold energy utilization system, the residual pressure released in the natural gas pressure regulating process can be utilized for generating electricity, and the released cold energy can carry out seawater desalination.

Description

technical field [0001] The present application relates to the technical field of natural gas pressure regulation, in particular to a natural gas residual pressure cold energy utilization system. Background technique [0002] As a clean energy, natural gas has a huge demand in my country. Natural gas resources are mainly distributed in the western regions of my country, while the demand for natural gas in the eastern coastal regions is relatively large. Natural gas is transported on land mostly through high-pressure pipelines. The pressure of most high-pressure natural gas transmission pipelines in my country is in the range of 8Mpa to 12Mpa. Before entering the user pipe network with a gauge pressure of 2.5Kpa, high-pressure natural gas needs to be regulated by a pressure regulating station. During the process of pressure regulation, there are huge Energy level transformation. If the gas transmission pressure drops from 10Mpa to 2.5Mpa, the specific pressure of natural gas...
