Abstract

The invention relates to a process for synthesizing liquefied natural gas. The method comprises: a catalyst bed is arranged in a methanation reactor, and the mixed gas reacts to generate methane under the action of the catalyst arranged on the catalyst bed; A humidity detector is provided in the device to detect the real-time humidity W in the methanation reactor; a solenoid valve is provided at the catalyst inlet to control the speed at which the catalyst enters the methanation reactor; The central control unit is wirelessly connected with the humidity detector and the solenoid valve respectively. The central control unit adjusts the opening and closing degree of the solenoid valve according to the real-time humidity detected by the humidity detector to control the quality of the catalyst to meet the speed of methane generation from the mixture. Through the real-time detection of the humidity in the methanation reactor, the opening and closing degree of the solenoid valve is adjusted according to the detected humidity value, so as to realize the control of the methane synthesis rate and the precise control of the synthesis process.

Description

technical field [0001] The invention relates to the technical field of natural gas preparation, in particular to a synthesis process of liquefied natural gas. Background technique [0002] The main component of liquefied natural gas (Liquefied Natural Gas, also known as LNG) is methane, and its preparation method is usually through a series of purification processes of natural gas, such as decarbonization and dehydration, then cooling to a certain temperature and then changing from gaseous state to liquid state to obtain With LNG, the volume of natural gas after liquefaction is reduced by 625 times, which is convenient for storage and transportation. [0003] my country's coke output is huge, and a large amount of coke oven gas is produced. Coke oven gas contains more combustible components and has great utilization value. How to use coke oven gas reasonably has attracted people's attention. Using the coke oven gas methanation process to produce LNG can obtain clean energy ...
