hpw is acetelene prepared from calcium carbide and ethylene dibromide???
Answers
Acetylene Generation Process Using Calcium Carbide
In various industrial environments, acetylene generation is initiated in acetylene producing generators. These equipment are sold in various capacities from 8 m3 to over 200 m3 per hour. Calcium carbide is introduced from the top of the generator shell into the water. The chemical formula of this reaction can be expressed as:
CAC2 + 2 H2O → C2H2 + CA(OH)2
This reaction should only be conducted under controlled conditions. The process unit should be equipped with pressure and temperature sensors, as well as non-return valves for safety purposes.
Acetylene Generator and Acetylene Production Using Calcium Carbide
Components of acetylene generation plant and their individual contribution is described here:
Generator: Here, calcium carbide is mixed with a large quantity of water to produce acetylene gas. The generator is fitted with the following accessories:
a. Automatic control sensors
b. Feeder
c. Hopper(s)
d. Agitator
e. Arrestor
Condenser: It helps cool down the acetylene gas produced in the generator.
Ammonia Scrubber: This vessel removes ammonia from the acetylene stream before purification.
Medium Pressure Drier: As the name suggests, the medium pressure drier helps dry the acetylene gas. It is also used to control the moisture content of the acetylene stream into the purifier. Anhydrous calcium chloride is used for the purpose.
Purifier: It mainly comprises of a purifying material, which helps separate phosphine and hydrogen sulphide created during the acetylene generation.
Purifier Scrubber: This component keeps any purifying material from entering the compressor.
Compressor: Acetylene is a flammable gas. It uses a compressor for acetylene that is surrounded by water, which cools the heat of compression after each stage.
