The invention provides a method, an apparatus and a system for controlling a natural gas adsorption column, and a purification system, wherein the method for controlling the natural gas adsorption column includes following steps: (1) sending a signal controlling a valve at an absorption section of the adsorption column to be opened; (2) obtaining the flow rate and the impurity content of natural gas in an inlet pipeline of the absorption section, and determining a preset adsorption time according to the flow rate and the impurity content of the natural gas, and sending a control signal controlling the valve at the absorption section to be closed and the valve at the regeneration section to be opened when the actual adsorption time reaches the preset adsorption time; and (3) obtaining the impurity content of natural gas in an outlet pipeline of the regeneration section in real time, and sending a control signal controlling the valve at the regeneration section to be closed and a valve at a cold-blowing section to be opened when the impurity content reaches a preset impurity content value. In the embodiment, the method selects different adsorption time on the basis of different impurity content and flow rate of the raw material natural gas, so that the impurities in the raw material natural gas can be adsorbed better, thereby increasing the efficiency and service life of an adsorbent and saving energy.
Description
technical field [0001] The invention relates to the technical field of natural gas purification, in particular to a control method, device, system and purification system of a natural gas adsorption tower. Background technique [0002] Natural gas is a kind of clean energy and chemical raw material. my country's long-distance natural gas pipelines use high-pressure gas transmission to transport natural gas to various natural gas gate stations, and each natural gas gate station decompresses high-pressure natural gas before transporting it to the downstream pipeline network. Or carry out liquefaction treatment into liquefied natural gas for users to use. [0003] Generally speaking, the raw gas from the natural gas gate station contains impurities such as water, mercury, and acid gas, which will have a serious impact on the system for depressurizing natural gas. For example, moisture in natural gas and natural gas will form hydrates under certain conditions to block pipelines,...
