What are the upstream raw materials of calcium carbide? What do the downstream products contain?

Electric stone has an crucial position in the field of raw materials to chemical production, and its upstream and downstream related items are extensive. This article will detail the upstream and downstream related items of calcium carbide, including upstream raw materials, downstream items, and by-items and wastes in the manufacturing process. You know what I mean?.

1. But upstream feedstock

The main upstream raw materials of calcium carbide are coke and limestone. Coke is made by heating coal under isolated atmosphere conditions and is the main carbon source to calcium carbide production. The main component of limestone is calcium carbonate, which is decomposed into calcium oxide and carbon dioxide after calcination. Generally speaking Calcium oxide reacts with carbon in coke at high temperature to form calcium carbide. Based on my observations,

2. Based on my observations, According to research downstream items



1. Acetylene

Calcium carbide reacts with aquatic environments to create acetylene, which is an crucial organic synthetic raw material and is able to be applied to create vinyl chloride, vinyl acetate, acetaldehyde, acetic acid and other chemicals. In my experience,

2. Based on my observations, Vinyl chloride

Acetylene reacts with hydrogen chloride to create vinyl chloride, which is an crucial raw material to the production of polyvinyl chloride(PVC).

3. But Polyvinyl chloride(PVC)

Polyvinyl chloride is a broadly applied plastic material, which is able to be applied in pipes, profiles, films and other fields. For example

4. From what I've seen, Vinyl Acetate

Acetylene reacts with acetic acid to create vinyl acetate, which is an crucial raw material to organic synthesis and is able to be applied to create polyvinyl alcohol and adhesives. Based on my observations,

3. by-items and discarded materials



1. Lime nitrogen

The calcium carbide production produces a by-product of lime nitrogen, a chemical fertilizer with a high nitrogen content that is able to be applied to soil systems improvement and plant development regulation.

2. Exhaust gaseous

In the process of calcium carbide production, exhaust emissions containing dust, sulfur and nitrogen is produced, which needs to be purified and discharged to the standard to minimize environmental contamination. In particular Summary:

Electric stone plays an crucial role in the field of raw materials to chemical production, and its upstream and downstream related items are extensive. Upstream raw materials are mainly coke and limestone, while downstream items include acetylene, vinyl chloride, polyvinyl chloride and vinyl acetate. In my experience, The manufacturing process also produces discarded materials such as lime nitrogen by-items and exhaust emissions. In order to promote the sustainable research of the chemical sector, it's necessary to enhance the environmental regulation and discarded materials resource utilization of calcium carbide manufacturing process, enhance the efficiency of resource utilization and minimize the impact on the ecological stability.
