  • ON

  • COAL CHEMICAL PLANT(OBJECTIVES)To clean Coke Oven Gas for using it as fuel for heating Coke Oven Batteries and for other consumers.

  • COAL CHEMICAL PLANT(CLEANING PROCESS)Co-gas coming out of Batteries has Tar, Ammonia,Crude Benzol and gas rich in Hydrogen and methane. The Tar ,Ammonia and Crude Benzol is removed from Co-gas before it is used as fuel in batteries.

  • COAL CHEMICAL PLANT(CLEANING PROCESS- WHERE & HOW)The Tar, ammonia and crude benzol is removed in Gas Cleaning Plant (RECOVERY PLANT).

    Tar is removed and sent to tar plant for the distillation to get tar products.

    Ammonia liquor is separated from tar and pumped back to gas collecting mains.

    Excess ammonical liquor is pumped to ammonia columns for further treatment. After treatment it is sent to MBC.

  • COAL CHEMICAL PLANT(CLEANING PROCESS- WHERE & HOW)Ammonia is removed in gas cleaning unit (Ammonium Sulphate plant). The gas passed through the 4-5% Sulphuric Acid Bath. Ammonia in Co-gas Reacts with acid and forms ammonium Sulphate.

    Crude Benzol is removed in Benzol Recovery unit of gas Cleaning Plant.

  • TAR DISTILLATION SECTION

    Tar received from FGC unit to TOS unit.From TOS tar is pumped to Decanter in TDS unit.After removal of water from decanter moisture content in tar reduces to 5-6%.Tar is heated in the first stage of furnace to a temp.of120-150 deg C and sent to first stage evaporator.In first stage evaporator complete de-moisturisation is done.

  • TAR DISTILLATION SECTION

    Tar after first stage evaporator is again heated in II stage of furnace to a temp. of 330-350deg C.In the second stage evaporator oil fraction is separated from top of second stage evaporator(35-40%) and soft pitch from bottom.The oil fraction is sent to the distillation column, where individual oil products are tapped , cooled collected in storage tanks.

  • TAR DISTILLATION SECTIONTHE PRODUCTS FROM DISTILLATION COLUMN ARE AS FOLLOWS:-Light oilPhenol Fraction.Naphthalene fraction.Wash oil.Anthracene oil-I & II.

  • PITCH COOLING AND LOADING AREAThe soft pitch from second stage evaporator is sent to reactors, where it is subjected to areation to increase the softening point to get the Alluminium grade pitch.Al. grade Pitch is cooled in dumping yards. It cut, bagged and dispatched to customers.Part of the soft pitch is used to make PCM by mixing it with Anthracene & Wash Oil mixture

  • NAFC

    Naphthalene fraction is further processed in NAFC unit to make Hot Pressed Napthalene(35-40Kg Cakes). The cakes are crushed, bagged and dispatched to customers.Drained Naphthalene oil is also produced in NAFC unit. It will have around 35-40% Naphthalene.

  • TAR & OIL STORAGE(OBJECTIVES)To store crude Coal tar and Oil products.

    To despatch Tar, PCM and Oil products to customers by road / rail tankers
