METHOD FOR SEPARATION OF METHANE, METHANE SEPARATOR, AND METHANE UTILIZATION SYSTEM |
摘要 |
<p>A methane separation method of the present invention at least includes: mixing the biogas and an absorbing liquid that absorbs carbon dioxide in a mixer so as to form a mixed fluid of a gas-liquid mixed phase; introducing the mixed fluid into a first gas/liquid separator so as to separate the mixed fluid through gas/liquid separation into methane and a CO 2 -absorbed liquid formed due to an absorption of the carbon dioxide by the absorbing liquid; recovering methane separated in the first gas/liquid separator; and supplying the CO 2 -absorbed liquid through a supply port of a membrane module comprised of a container and a plurality of hollow fiber permeable membranes built therein to inside of the membranes so as to make the CO 2 -absorbed liquid permeate the permeable membranes, and lowering a pressure outside the permeable membranes to a level lower than that inside the permeable membranes.</p> |
