Abstract

The invention discloses a storage and usage system and method for bio-natural gas. A gas source pretreatment unit, a hydration unit, a hydrate storage tank and a hydrate resolver in the system are connected through a one-way pipe in sequence, and an exhaust port of the hydrate resolver is in butt joint with a gas discharging pipe. The pipe between the gas source pretreatment unit and the hydrationunit is provided with a valve and a gas-pressure meter. The pipe of the hydration unit and the hydrate storage tank and the pipe between the hydrate storage tank and the hydrate resolver are providedwith slurry pumps and valves. The method and system are based on the same technical principle. According to the storage and usage system and method for the bio-natural gas, the bio-natural gas sourceis pressurized, pre-cooled and subjected to other pretreatment, the efficiency of the hydration reaction of the bio-natural gas can be further improved, and thus the bio-natural gas is efficiently stored. In addition, the storage system and method for the bio-natural gas have the advantages of being economical, safe, efficient, low in cost and energy consumption, high in adaptability and the like.

Description

technical field [0001] The invention belongs to the field of biological natural gas energy utilization, and in particular relates to a biological natural gas storage system and storage method. Background technique [0002] Bio-natural gas refers to gas converted from biomass, and its main components are methane, carbon dioxide, nitrogen, hydrogen sulfide and other gases. As a new energy model, bio-natural gas is a new technology for comprehensive utilization of energy that integrates energy saving and environmental protection. Bio-natural gas can be purified to obtain high-purity methane, which is a clean energy source with high calorific value and no pollution. At present, bio-natural gas is mainly used for low-grade thermal utilization, but with the continuous development of biogas technology and biogas engineering, the mid-to-high-end utilization of bio-natural gas has received extensive attention, and the safe and efficient storage of bio-natural gas has become an impo...
