Chemical Engineering

Water Treatment Chemicals

NTPC operates various thermal power plants across India, and these plants require significant quantities of water for cooling and other processes. To maintain operational efficiency and environmental compliance, NTPC uses water treatment chemicals. These chemicals are essential for

  • Cooling Water Treatment: Chemicals are used to prevent scaling, corrosion, and biological fouling in cooling water systems of power plants.
  • Boiler Water Treatment: Chemicals are also used to treat boiler feedwater to prevent corrosion and scale formation inside boilers.

Environmental Management

NTPC places a strong emphasis on environmental sustainability and compliance with regulatory standards. Chemicals are used in environmental management practices such as

  • Air Pollution Control: Chemicals may be used in flue gas desulfurization (FGD) systems to reduce sulfur dioxide emissions from coal-fired power plants.
  • Effluent Treatment: Chemicals are utilized in wastewater treatment plants to treat effluents before discharge to ensure compliance with environmental regulations.

Mechanical Engineering

Power Plant Operations

  • Steam Turbines: NTPC operates steam turbines in its thermal power plants to convert thermal energy from steam into mechanical energy, which is then used to generate electricity.
  • Gas Turbines: Some NTPC plants also utilize gas turbines to generate electricity by burning natural gas or other fuels.
  • Boilers: Mechanical engineers at NTPC are involved in the design, operation, and maintenance of boilers used to generate steam from water heated by burning fossil fuels.

Mechanical Systems

  • Pumps and Compressors: Mechanical engineers oversee the operation and maintenance of pumps and compressors used in various processes within power plants, including water circulation, fuel handling, and air compression.
