Chlor-Alkali & Ammonia Industry Flashcards
What are the similarities of Chlor-Alkali & Ammonia Processes?
Both Chlor-Alkali & Ammonia production share hydrogen gas as a common by-product, which can be utilized in other industrial applications.
A chemical process that uses electricity to drive a chemical reaction, often to split a molecule into its constituent elements
Electrolysis
The negatively charged electrode in an electrolytic cell where reduction reactions occur.
Cathode
The positively charged electrode in an electrolytic cell where oxidation reactions occur.
Anode
Define Chlor-Alkali process
An industrial process that uses electrolysis to produce
chlorine gas and sodium hydroxide (caustic soda) from sodium chloride (common salt)
Explain what is Haber-Bosch Process.
An industrial process that uses high pressure and temperature to synthesize ammonia from nitrogen and hydrogen gases
A mixture of nitrogen and hydrogen gases used as feedstock for ammonia synthesis
Synthesis Gas (Syngas)
A chemical process that converts methane (natural gas) into hydrogen gas and carbon dioxide.
Reforming
A substance that speeds up a chemical reaction without being consumed by the reaction, often used in ammonia synthesis
Catalyst
The process of combining nitrogen and hydrogen gases to form ammonia (NH3), often using a catalyst and high pressure and temperature conditions.
Ammonia Synthesis
Sodium hydroxide (NaOH), a strong alkaline substance produced in the Chlor-Alkali Process
Caustic soda
