OILY SLUDGE – SOURCES AND TREATMENT
I. TANK BOTTOM SLUDGE:
17 crude tanks are located in CPCL’s Mandatory Tank Form campus. Each crude tank is decommissioned once in 7-10 years for cleaning of tank bottom sludge and for Maintenance works. Tank bottom sludge is processed by in-situ process to prevent VOC emission which is prominent in ex-situ sludge treatment and hence in-situ process is eco friendly as the total process occurs in a closed system. Brief description of in-situ process is depicted as below In-situ sludge treatment in tank: This consists of three modules placed near the tank to complete the treatment
a) Suction module b) Re-circulation module c) Solid liquid separation module
a) Suction module
This consists of centrifugal pump and a pre-heater. This is utilized to put the slurry in circulation module in hot condition.
CPCL Environment Statement 2017-18
6 | P a g e
b) Re-circulation module This consists of slurry container for receipt of sludge from tank and diluents, jet nozzles to establish high-speed jet inside tank so that the solidified sludge is broken into small particle and aid in dissolving the solids. Jet pressure is boosted by using air compressor
c) Solid liquid separation module After jet mixing and dissolving the sludge in diluents for sufficient time the liquid is passed through high-speed centrifuge to separate oil from sediments. In-situ cleaning of tank bottom sludge process has been adopted for tank 114 during 2017-18 and details of the same is mentioned below: Tank 114:
Item Description Qty in KL Qty of Processed Sludge 5105
II. ETP OILY SLUDGE/OTHER TANK SLUDGES: ETP oily sludge is generated from Physico-Chemical treatment in the ETPs. During decommissioning of products and slop tanks for M&I activities, the accumulated sludge from tank bottom are stored in concrete lined pits. Storage of Sludge: CPCL has constructed lined lagoons for storage of oily sludge and treated sludge. CPCL has built a state of art RCC storage structure in 2004 with leachate collection system and pumping. Oily sludge stored in the tank is processed mechanically to recover the oil as below. Mechanical Treatment of Oily sludge ( Ex-situ process) : Steps involved in mechanical treatment of oily sludge are as below
Use of steam to liquefy the oily sludge; mix with cutter stock; pass through strainer / vibro-screen; mix the contents with chemical demulsifier ; pass through heat exchanger followed by decanter centrifuge and separate solids and liquids (water, oil)
The feed sludge, taken in batches of 20 KL each time, is received on Vibro-screen
fixed top of the Tank for removal of debris like leaves, rags, stones, etc. Vibro-screen is fitted with SS mesh of different sizes for removal of debris.
Cutter stock from LCO tank is mixed with the sludge for dissolving the heavy oil fraction and demulsifier poly-electrolyte from Chemical dosing tank for breaking the emulsion as also hot water (from Hot water tank) for washing the debris.
The conditioned feed is then routed to Heat exchanger where the temperature is raised to 80-90 C using steam and then pumped to a Decanter Centrifuge located at 10 ft from ground level
CPCL Environment Statement 2017-18
7 | P a g e
Decanter centrifuge separates the oily sludge in to 3 phases namely oil, water and solids. Hot water is pumped in to the Centrifuge for washing the solids (final sediments) free of soluble salts and also to clean the Centrifuge after completing each batch.
Membership of Common Landfill Facility: CPCL has taken membership in Industrial Waste Management Association (IWMA) for the disposal of spent catalyst falling under Schedule I & II of Hazardous Waste Management and Handling Rules 2016 to M/s Tamilnadu Waste Management Limited, Gummudipoondi (the only authorized site by M/s TNPCB). The renewal of membership is done every year regularly by remitting the membership fee as stipulated by M/s IWMA.

PART - F
The characterization (in terms of composition and quantum) of hazardous as well as solid wastes and indicates disposal practice adopted for both these categories of wastes.
I. CHARACTERIZATION OF SOLID WASTE:
Characterization of Hazardous solid waste is done by conducting comprehensive analysis of sample as and when generated in the lab operated by M/s Tamilnadu Waste Management Limited authorized by TNPCB. Since in the year 2017-18, no new hazardous waste was originated, no analysis has been carried out. Further, M/s NEERI has carried out “Comprehensive Audit of Solid Waste Generation at M/s Chennai Petroleum Corporation Ltd.,” Chennai in the year 2013 to characterize various waste from process and pollution control facilities.
II. DISPOSAL & WASTE MINIMIZATION PRACTICES:
Oil Sludge: Minimization of sludge and recovery of oil from sludge in crude tanks is done by adopting the following steps: Side mixers (3 Nos.) in crude storage tanks to re-suspend the sludge into crude. Hot gas oil recirculation to recover oil from the sludge.
Maintaining high temperature in BH crude tanks to eliminate sludge buildup by using
steam coils. Mechanical treatment of sludge thereby ensuring sludge minimization and avoiding
accumulation
In-situ tank bottom sludge process Disposal: Please refer write up on sludge management in CPCL under Part-D Effluent Treatment Plant Sludge: After oil extraction to the maximum possible extent, oily chemical sludge is stored in
lined pits then it is disposed to TNWML Gummudipundi
Tertiary Treatment Plant Sludge: Bio-Sludge: After de-watering in drying beds used either for greenbelt or earth filling
