Problems solved by technology

[0009] However, biogas sources in Taiwan are quite abundant. In the past, most of them were not fully utilized and were allowed to be discharged, resulting in waste of energy and air pollution. Natural gas is low in odor and corrosive, which limits its utilization

Abstract

The invention relates to a device for purifying carbon dioxide and separating methane. The device comprises a blower, a vacuum pump, a valve assembly and more than one carbon dioxide purification tower and is used for removing the carbon dioxide from gas and can be further combined with a sulfide purification device to remove the sulfide and the carbon dioxide from the methane at the same time and effectively separate the methane. The invention also provides a relevant method for purifying the carbon dioxide and separating the methane. Through the method and the device for purifying the carbon dioxide and separating the methane of the invention, the carbon dioxide can be effectively purified and the methane can be separated at the same time; and methane resources can be sufficiently and effectively used so as to realize the effective use of natural resources.

Description

technical field [0001] The invention relates to a device and method for carbon dioxide purification and biogas methane separation, in particular to a device that can effectively remove carbon dioxide in gas, and the carbon dioxide purification device is combined with a sulfur compound purification device to effectively remove biogas at the same time sulfur compounds and carbon dioxide and separate methane from the biogas. Background technique [0002] Biogas is a combustible gas produced by microbial fermentation of organic matter in an anaerobic environment under certain temperature, humidity and pH conditions, and because this gas was originally found in swamps, lakes or ponds Therefore, it is called biogas. While biogas contains a variety of gas components, the most important combustible component is methane (CH 4 ). [0003] In addition, the process in which biogas bacteria decompose organic matter to produce biogas is called biogas fermentation. According to the rol...
