Acetylene Generation Process

The world's leading calcium carbide supplier.

Acetylene Production

chemical Equation:

CaC2 + 2H2O → C2H2 + Ca(OH)2

Applications of Acetylene:

1.Acetylene is the basis for the production of many important chemical raw materials, such as ethylene, propylene, and vinyl chloride.

2.Acetylene is an important raw material for the synthesis of chloroprene rubber (CR) and PVC.

3.Acetylene derivatives are used in the manufacture of certain pesticides and pharmaceutical chemicals.

Influencing Factors:

The gas yield and impurity content of calcium carbide directly affect the yield and purity of acetylene.

The correct size of calcium carbide can improve reaction efficiency and reduce safety risks during the production process.

The Process of Generation of Acetylene Gas

In industrial acetylene production, the calcium carbide process has become the mainstream technology due to its maturity and broad applicability. The reaction between calcium carbide and water generates acetylene, which takes place in an acetylene generator. This can be done using either a dry or wet process. In the wet process, calcium carbide is added to water, while in the dry process, water is sprayed onto the calcium carbide.

The produced acetylene gas must pass through a purification tower to remove impurities such as hydrogen sulfide and phosphine, improving its purity. Following this, the acetylene gas is pressurized using a compressor and further purified and dehydrated in an oil-water separator and a dryer. Finally, the purified acetylene gas is filled into steel cylinders containing acetone to form dissolved acetylene, ensuring safe storage and transportation.

TYWH Solutions

impurity content affects acetylene purity

Except H2S and PH3 content meet Chinese standards. We also use five 1500W powerful electromagnets to remove iron impurities, and manually inspect to remove visible impurities such as ferrosilicon and carbon rods. Through this series of quality control measures, we ensure to provide customers with high-quality calcium carbide with lower impurity content.

Slow settling of calcium carbide mud affects production efficiency and safety

We suggest using flocculants to promote the aggregation of calcium carbide mud particles, or alternatively, employing physical or chemical methods for the separation of calcium carbide mud.

Improper storage of calcium carbide poses safety risks

To ensure the safe storage of calcium carbide, we inject nitrogen into each drum to eliminate residual air and flammable gases, effectively preventing weathering and improving transportation safety. We provide MSDS certificates and conduct safety training to ensure customers understand proper storage and handling practices, ensuring the safe management of calcium carbide throughout the process.
