A natural gas preparation system and an integrated skid-mounted natural gas preparation system

Abstract

The invention discloses a natural gas preparation system and an integrated skid-mounted natural gas preparation system. The natural gas preparation system includes: a subcritical water preparation device, an atomization device, and a two-phase reaction vessel, and the atomization device and the subcritical water preparation device are respectively connected to the two-phase reaction container; the subcritical water and mist produced by the subcritical water preparation device The atomized coal-water slurry in the atomization device reacts in the two-phase reaction vessel to produce natural gas. The invention produces natural gas through the reaction of subcritical water and atomized coal-water slurry, and proposes a new natural gas preparation process, which can realize the integration of production equipment, environmental protection and cost saving.

Description

technical field [0001] The invention relates to the field of coal-to-natural gas, more specifically, to a natural gas preparation system and an integrated skid-mounted natural gas preparation system. Background technique [0002] my country's domestic natural gas production capacity is limited and cannot meet the rapid growth of domestic demand. Therefore, the current natural gas consumption structure in my country still accounts for a large proportion of imported gas sources. In 2018, the national natural gas production was 107.7 billion cubic meters, the consumption was 147.1 billion cubic meters, and the gap between supply and demand reached 39.4 billion cubic meters. From January to April 2013, my country's natural gas production was 40.2 billion cubic meters, an increase of 7.7% year-on-year, and imports were about 17.1 billion cubic meters, an increase of 32.3%. The substantial increase in imported gas sources shows that the current domestic gas source supply still can...

Problems solved by technology

Although the above-mentioned projects have alleviated the shortage of natural gas resources, they have also brought about problems such as serious pollution, huge waste of land, and high costs.

The main reason for the correction is: traditional coal-to-natural gas technology relies heavily on expensive catalysts and complicated processes, and the existing equipment is often large-scale equipment, which occupies a large area and is not conducive to movement, and the applicable scenarios are very limited
