Acetylene. Acetylene also called as-ethyne is the chemical compound with the formula C2H2. It is a hydrocarbon and the simplest alkyne. This colorless gas is widely used as a fuel and a chemical building block. It is unstable in pure form and thus is usually handled as a solution. Pure acetylene is odorless, but commercial grades usually have a ...

Question: Acetylene gas (C_2H_2) is burned completely with dry air in a steady flow combustion process. The air-fuel ratio on a mass basis is 15.9. The fuel and air enter the combustion chamber at 25 degree C, and the products leave at 1500K. Determine the following: the balanced reaction equation the heat transfer (kJ/kmol) for the process.

The reaction conditions were optimized: at 240–250°C, 8.0 MPa, an acetylene residence time of 0.5 h, a CO/C 2 H 2 ratio of 1.3, and NiBr 2 and CuBr 2 concentrations of 0.1 and 0.05 wt %, respectively, a high AA yield (80%) and a low yield of by-products (6 wt % acetaldehyde) were retained over a 120 h period.

In order to solve the problems existing in dry-process acetylene device,some optimization measures on iron removal system,crushing system,washing system and dust removal system were taken,then the stable operation of the device was achieved.

A wet- and dry-process feasible efficient deep-blue emitter is highly desired to realize, respectively, low cost roll-to-roll fabrication of large area and high performance devices with precise ...

A process for producing ethyne by dry method is carried out by: mixing water with calcium acetylide powder in proportion of 1.1-1.9:1, and spraying water on calcium acetylide powders in ethyne generator and hydrolyzing to generate ethyne. Calcium acetylide rate at outlet of residual slag machine is 99.5-99.85 wt%, ethyne recovery rate reaches to 98.5 wt%, …

Current situations of traditional wet acetylene generation process were introduced.The wet process and the dry process were compared.It was regarded that if the wet process was modified in aspects of crushing,transportation and feeding of calcium carbide,reaction control and gas purification,the consumption of calcium carbide could be reduced …

Acetylene is used for welding and cutting. The welding process that uses acetylene is known as oxy-fuel cutting or gas cutting. This method is used to cut or weld materials that require temperatures as high as 3,500 °C (6,330 °F). Among all other gases, acetylene is capable of producing the hottest flame.

The acetylene generator is a device for the production of acetylene by a chemical reaction. The interaction of calcium carbide with water leads to the isolation of the desired product. ... In addition, welders often use the VC, but only with a "dry process". Very rarely, but still combined generators are used. They combine the features and ...

Industrial processes to produce acetylene include the calcium carbide method [2], partial oxidation of natural gas [4], steam cracking of petroleum …

Step 2: COOLING Chamber. The acetylene generated is passed from the generator chamber through wet type flashback arresters into a low pressure condenser. Here, the temperature of the gas is lowered by water cooling. This also removes part of the moisture in the acetylene in the form of condensed water.

Industrially, acetylene is formed in one of two types of generators. In the wet generator, an excess of water is used. In a dry generator, an approximately stoichiometric amount of water is used, and the calcium hydroxide is obtained as a pourable powder. The heat of reaction is removed by evaporation of a portion of the added water.

The water consumption for the preparation of PVC using dry acetylene is only one-tenth of that required for wet acetylene process. The utilization of carbide slag is enhanced and outstanding advantages are achieved with regards to environmental protection and water savings. Therefore, dry acetylene technology has developed rapidly.
