Calcium Carbide 295L/Kg CaC₂ (80–120mm): Factory-Grade Acetylene Production

Calcium carbide lumps sized 80–120mm​ with a guaranteed gas yield of 295 liters of acetylene per kilogram (L/Kg)​ are a premium industrial grade, designed for large-scale acetylene generation in factories and heavy-duty applications. Their oversized particles, high purity, and consistent gas output make them ideal for chemical plants, steel mills, and welding operations requiring reliable, high-volume acetylene supply. Below, we explore their specifications, gas yield performance, and key industrial uses.

 

1. Product Overview: 80–120mm Calcium Carbide (295L/Kg)​

This grade of calcium carbide is engineered for factory-scale acetylene production, with strict controls on size, purity, and gas yield to ensure optimal performance in industrial reactors and generators.

2. Gas Yield: 295L/Kg Acetylene Performance​

The 295L/Kg gas yield​ is a critical metric, indicating the volume of acetylene (C₂H₂) produced when 1 kilogram of calcium carbide reacts completely with water. This yield is achieved through:

High Purity: ≥92% CaC₂ content ensures maximum acetylene output per unit mass.

Controlled Particle Size: 80–120mm lumps react slowly and steadily, preventing rapid gas bursts and ensuring consistent supply to reactors.

Low Impurities: Minimal sulfur/phosphorus reduces side reactions, optimizing acetylene purity.

Reaction Basis​

The gas yield is derived from the hydrolysis reaction:

CaC2​+2H2​O→C2​H2​↑+Ca(OH)2​

Theoretical yield: ~373 L/Kg (for 100% CaC₂).

Actual yield (295L/Kg): Reflects 92–96% CaC₂ content, accounting for minor impurities and reaction inefficiencies.

3. Industrial Applications of 80–120mm Calcium Carbide​

3.1 Chemical Manufacturing: PVC & Synthetic Rubber Production​

Factories producing PVC, vinyl chloride, and synthetic rubber rely on 80–120mm calcium carbide for:

Continuous Acetylene Supply: Steady gas flow feeds reactors for vinyl chloride synthesis (PVC monomer) and butadiene production (rubber precursor).

High Throughput: Large lump size suits massive acetylene generators (10–50 tons/day capacity), aligning with industrial-scale chemical plants.

3.2 Steelmaking: Large-Scale Deoxidization​

In electric arc furnaces (EAFs) and basic oxygen furnaces (BOFs), 80–120mm lumps are used for:

Slow Dissolution: Gradual breakdown in molten steel ensures uniform deoxidization and desulfurization, reducing slag formation.

Cost Efficiency: High gas yield per kilogram lowers raw material costs for steel producers.

3.3 Heavy-Duty Welding & Cutting​

For shipbuilding, pipeline construction, and heavy machinery repair, 80–120mm calcium carbide powers stationary acetylene generators:

Sustained Flame: Steady acetylene output supports continuous welding of thick steel plates (up to 300mm thickness).

Durability: Resists crumbling in generators, minimizing downtime and maintenance.

3.4 Acetylene-Based Chemical Synthesis​

Factories producing acetic acid, ethylene glycol, and other acetylene derivatives use 80–120mm lumps to ensure:

Consistent Feedstock: Reliable acetylene supply for multi-step chemical processes.

Purity Control: Low sulfur/phosphorus levels prevent contamination of final products.

4. Advantages of 80–120mm Calcium Carbide (295L/Kg)​

High Gas Yield: 295L/Kg ensures maximum acetylene output per kilogram, reducing raw material consumption.

Steady Reaction: Slow, controlled gas generation prevents pressure fluctuations in generators.

Mechanical Stability: Large lumps resist breakage, minimizing dust and fines during handling.

Factory-Optimized: Designed for large-scale reactors and continuous production lines.

5. Storage & Handling for Factory Use​

Storage: Keep in airtight, moisture-proof steel silos or bulk bags with desiccants to maintain gas yield.

Environment: Store in dry, well-ventilated areas (temperature <40°C, humidity <50%).

Handling: Use cranes or forklifts for bulk loading; avoid dropping lumps to prevent breakage.
