EPSILON CARBON PRIVATE LIMITED ECPL CoalTar Distillation -300,000tpa Karnataka
ProjectProfile
General TheEpsilon CarbonprivateLimited is aspiring to emergeasadynamiccompanyin India in the field of coal tar processing for manufacture ofvarious value added products.
The proposed green-field Coal tar distillation plant coupledwith solidpitchmeltingunitisproposedtosetupwith Coal tar processing capacity of 300,000tpaat Toranagallu in Bellary district of Karnataka.
Process Description: The coal tar are separated by distillation process. Coal tar containing several chemical compounds with major being Coal tar pitch,Naphthalene,Wash Oil, Light Oil, Phenol Oil & Anthracene oil. Following are major manufacturing of process & Products: 1. Coal Tar pitch (Binder Grade Pitch) 2. Zero QI /Impregnated Pitch 3. Naphthalene &Naphthalene sulfonate formaldehyde (NSF) 4. Oils- Carbon Black Oil (CBO) ,Light oil, Phenol oil, Wash oil , Anthracene oil By Products: 5. Sodium Phenolate 6. Ammonical water
1. Binder Grade Pitch: Soft Pitch from the bottom of pitch column is sent to pitch column for further processing to modified pitch to increase QI content and blended with required high QI pitch to produce binder grade pitch for aluminum industry.
2. Impregnated Pitch : Blending of coal tar and wash oil in specific ratio, dehydration up to 180℃ to separate moisture content in coal tar. The dehydrated mixture is transferred to settling tank for reduction of QI. (Settling tank provide draw-off valve for QI sampling). QI value less material transfer to further distillation (Removal of Oils) to produce Impregnated Pitch.

3. Carbon Black Oil(CBO): Blending of Soft Pitch from the bottom of pitch column and Anthracene oil in specific ratio with required specific gravity to produce carbon black oil for tyre industry.
4. Naphthalene &Naphthalene sulfonate formaldehyde (NSF) Three mixed oil fraction from distillation column is mixed with dilute alkali and treated in washing separating towers. The phenol fraction forms Sodium Phenolate which passes to aqueous layer as a byproduct. The washed fraction is further distilled in naphthalene columns to obtain wash oil & crude naphthalene. The crude naphthalene oil is further crystallizedto pure naphthalene. During Crystallization process residual naphthalene oil is generated which is treated with Sulphuric acid (Sulfonation Reaction), followed by formaldehyde (Condensation) and further neutralized by sodium hydroxide to produce naphthalene sulfonated formaldehyde. (NSF).
5. Oils- Light oil,Phenol oil & Anthracene oil Tar is pumped through pre heaters and fed to dehydration column in which azeotropic distillation takes to remove Light oil and moisture content in the tar from the top of column. Light oil & moisture is further separated in a separator to obtain pure light oil. Dehydrated tar from the bottom of dehydration column is pumped to pitch column. The overhead vapor from pitch column flow to the distillation column in which they are separated the top fraction contains phenol oil, the middle fraction contains naphthalene oil along with phenols and wash oil & the bottom product contains Anthracene oil.
