Embodiment Construction

[0035] see figure 1 , figure 2 , a method for continuously preparing solid natural gas, comprising the following steps in sequence:

[0036] (1) The raw natural gas from the wellhead or the pipeline passes through the shut-off valve 1 and adjusts the pressure through the pressure regulating valve 2, and the water enters the natural gas continuously and evenly through the flow regulating valve 3 to moisten the gas;

[0037] (2) The water-containing natural gas enters the reactor 4 through the gas flow inlet 41, and a plurality of nozzles 42 that form a certain angle (60-90 degrees) with its radial direction are evenly distributed around the cylindrical reactor 4, and the water-containing natural gas flows through the nozzles. Jet flow 43 is formed, and throttling expansion occurs at the same time. The reaction zone 44 in the reactor rotates at a high speed to rapidly generate solid hydrate, and then enters the centrifugal zone 45;

[0038] (3) The airflow containing solid hy...

Abstract

A process for continuously preparing the solid-state natural gas includes such steps as continuously moistening the pressurized natural gas by water, flowing the wet natural gas into reactor, spraying them from multiple nozzles of reactor for throttling expansion while high-speed rotating in reactor to quickly generate solid hydrate, solid-gas separation, discharging the particles of solid hydrate, mixing the unreacted gas with raw material gas in compressor while compressing, wetting, and continuing reaction in reactor. Its advantages are low cost, high productivity and high utilization rate of raw natural gas.

Description

technical field [0001] The invention relates to natural gas solidification technology in the field of natural gas storage and transportation. Background technique [0002] Solid Gas Technology (GTS) is to convert natural gas from gaseous state into solid hydrate form, making it easy to transport and re-conversion into gaseous natural gas. Because it significantly reduces the cost of natural gas storage and transportation, and improves the economy and safety of natural gas storage and transportation, it has received widespread attention from the industry and is a new technology that is being researched and developed. Compared with other forms of storage and transportation of natural gas, such as pipeline transportation, CNG (compressed natural gas) technology, and LNG (liquefied natural gas) technology, solidified natural gas technology has unique advantages, mainly in: [0003] (1) Easy to prepare. The pressure and temperature conditions for preparing solid natural gas are...
