Problems solved by technology

In recent years, some units in our country have also begun to test the use of water-soluble additives to produce welding and cutting gases such as alkanes and olefins, but the effect is not good, and the performance cannot meet the requirements
When this kind of gas is used for welding and cutting, one is that the preheating time is long during cutting, and the waste of gas is serious; the other is that the welded metal body has low bearing capacity, insufficient pressure, and serious oxidation, which is difficult for customers to accept due to many reasons.

Abstract

The present invention discloses an environmental friendly high energy mixed light hydrocarbon industrial gas, which is formed by mixing multi-purpose synergic agent and alkyl alkene according to 1 to 3 per mille of proportioning by weight. The alkyl alkene is formed by mixing light hydrocarbon gas and heavy hydrocarbon gas according to 1: (0 to 0.2) of proportioning by weight. The multi-purpose synergic agent is formed by preparing 120 # solvent oil, alcohol, methyl tert-butyl ether jiajishudingjimi, china wood oil, butyl-ferrocen ferrocene, sodium napthionate, cupric cyclo alkanes and potassium hydroxide according to a certain proportion. The present invention has the advantages that the energy consumption is low, the pollution is weak, the cost is low, the present invention is safe, the temperature of the flame is higher than the acetylene, the present invention can completely meet the requirement of the industry fuel gas, and can be suitable for operating in the severe cold area and on ships, and the fuel gas is saved by above 30 percent.

Description

technical field [0001] The invention relates to the technical field of industrial gas, in particular to an environment-friendly high-energy mixed light hydrocarbon industrial gas and a production method thereof. Background technique [0002] In today's society, people use acetylene gas for welding and cutting. The use of acetylene has the disadvantages of high energy efficiency, large pollution, unsafe, high price, etc. The production of a ton of calcium carbide requires 3600 degrees of electricity and 1 ton of coke, and it also produces 3.3 tons of pollutants, and also emits toxic gases such as sulfides and phosphides. . The cost price of a bottle of 5 kg of acetylene is 55 yuan, which is very expensive. [0003] Now using liquefied petroleum gas industrial gas, the ambient temperature requirements are very high. When the ambient temperature is lower than minus 15 degrees Celsius to minus 20 degrees Celsius, when the gas consumption is large, the evaporation will be great...
