Problems solved by technology
As a clean energy source, liquefied petroleum gas has many advantages and significant environmental protection benefits, but it also has certain limitations, such as large price fluctuations that lead to unstable gas production costs and high prices, and the demand gap in the domestic liquefied petroleum gas market. 7 million tons per year, completely dependent on imports, the risk is high, especially since there is no strategic reserve of a certain scale in China, it is difficult to avoid the risk of international speculative capital or oil monopoly capital making waves

Embodiment Construction
[0023] Such as figure 1 Shown is the production process flow chart of the present invention.
[0024] The topping oil in the raw material tank area is pressurized by the hydrocarbon pump and sent from the topping oil pipeline to the distribution pipe of the gas making device area, and then sent from the distribution pipe to the upgrading spray gun, heating spray gun, ignition spray gun, and heating spray gun. The excess topping oil is decompressed by the pressure control valve and then returned to the topping oil storage tank to ensure a constant pressure of the topping oil header in the gas production device area.
[0025] A set of gas-making device adopts two-series production lines. The cycle time of each cycle of each production line is 120 seconds, which is mainly divided into heating and upgrading stages. The reactor needs to be purged with steam and air between each stage to ensure safety and improve thermal efficiency. The heating and upgrading stages of the two-series pr...

The invention discloses a method for producing pipeline gas by using liquid light hydrocarbons as raw materials, which comprises the following steps in sequence: (A) heating a combustion reforming furnace; (B) water vapor purging, that is, passing water vapor into the combustion reforming furnace ; (C) upgrading, that is, after the raw material liquid light hydrocarbon enters the mixing chamber and is fully mixed with the steam, under the action of the catalyst in the reforming chamber, CO and H are generated 2 ; (D) The modified gas enters the cooling and heating tower to adjust the calorific value and combustion characteristics of the gas. The invention uses liquid light hydrocarbons as raw materials to produce pipeline gas, greatly reduces the cost, fully utilizes the existing liquid light hydrocarbon resources, and has considerable economic, social and environmental benefits.
Description
Technical field [0001] The invention relates to a method for producing urban pipeline gas by using liquid light hydrocarbons as raw materials. Background technique [0002] In nature, substances composed of two elements of hydrocarbon and hydrogen are called hydrocarbons, such as oil and natural gas. Natural gas, liquefied petroleum gas, stable light hydrocarbons, gasoline, diesel, etc., derived from petroleum extraction and refining production are also hydrocarbon substances. From the perspective of the entire petroleum composition, the light hydrocarbons used for fuel gas feedstock are a certain distillation range in the petroleum composition. From the perspective of the arrangement of petroleum carbon atoms, the first stage is natural gas, with carbon atoms of 1 or 2, called methane or ethane. alkyl. The second stage is liquefied petroleum gas with C3 and C4 carbon atoms. These two sections are used for chemical raw materials and high-quality gaseous fuels, both of which are g...
