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.


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


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.

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

PART - G Impact of the pollution control measures on conservation of natural resources and consequently on the cost of production Following measures have been taken to reduce the impact on environment & cost of production and to conserve natural resources:

Basic pollution control measures (viz., effluent treatment plants, air pollution control equipment, monitoring equipment’s etc.) have been installed for complying with environmental statutory requirements and is in continuous operation within the refinery. In addition to pollution control measures, use of Cleaner Technology in process operations has been resorted which helps in conservation of natural resources and consequently reduces the cost of production. Cleaner Technology includes the following:

I. Use of new process technology / change to eco-friendly manufacturing processes

(i) New Effluent Treatment plant (ETP4) combined with DM plant was commissioned to treat the effluents generated from DCU facilities at a cost of Rs 220 Crore.

(ii) Construction & laying of new 42” Crude Oil pipeline with enhanced safety features is in progress from Chennai Port Trust to Manali Refinery at an estimated cost of Rs 257.87 Crore to have a better reliability. Design of the above said pipeline includes the latest leak detection and automatic isolation system.

(iii) CPCL has commissioned 5.8 MGD Desalination plant in the year 2010 at a cost of Rs 231.34 Crore thereby reducing the fresh water receipt from CMWSSB so as to supply the equivalent water to city.

(iv) A new SRU plant (2 X 100 TPD) is under commissioning to treat the sulphur laden stream from Delayed Coker Unit ( DCU).

(v) As part of Auto Fuel Policy, the entire MS and Diesel produced is conforming to BS-IV since 1st April 2017. Further, CPCL is in the process of implementing BS-VI in line with Auto Fuel Policy directions.

II. Use of environment-friendly inputs / products in the manufacturing processes

(i) CPCL is in the process of implementing RLNG project in a phased manner which will result in the reduction of pollutant load to the atmosphere. Target for the above project is end of 2018.

(ii) Low Sulfur fuel (LSHS) is being used in Refinery to reduce sulfur emissions in to the environment.

(iii) Low NOx burners are in use in boilers and process furnace heaters of DHDS, Ref-III and Ref II

III. Development / production / distribution of eco-friendly products

a. Volatile Organic Compounds (VOC) collection & Removal system

CPCL has commissioned and put in continuous operation of VOC collection and removal system for ETP II. The VOCs generated from the oil handling ETP equipments such as API, TPI, DAF, pH adjustment tank, Flash mixing tank, Flocculation tank, sludge sump


10 | P a g e

supernatant sump and slop oil is collected and stripped of by passing through Activated Carbon Filters. The existing ETP-II open surge pond was decommissioned and new closed tanks (Three nos.) have been installed and commissioned.

b. Provision of Dome Roof tanks for Naphtha tanks with Nitrogen Blanketing:

Dome Roof tanks with nitrogen blanketing instead of floating roof tanks (4X 3000 KL) with double seal have been provided for Naphtha tanks in Euro IV projects which results reduction of 4 MT/year of VOC. IV. Reduction in the consumption of Fresh Water (i) A Tertiary cum RO plant installed in 1991 for reclamation of city sewage about 2.5

PART - H Additional measures / investment proposal for environmental protection including abatement of pollution and prevention of pollution Investments Investments made under Environmental Management System in CPCL are presented in Annexure - VI Occupational Health Services & Work environment monitoring Occupational Hygiene Survey at different plants is regularly carried out by our OHS department. The work environmental concentrations of various chemical hazards, personal noise exposure & heat stress encountered in the work place is measured during the survey. Report of the findings of work environment monitoring carried out during the year 2017-18 is given in Annexure –VII. Proposals / Projects implemented recently or under advanced stage of commissioning: WATER ENVIRONMENT: CPCL took several major initiatives to improve treated water quality. The following are some of the prominent steps taken: Online Effluent Monitoring System As part of Environment Management and compliance of directions issued by CPCB / TNPCB as well as to have a close monitoring of ETP’s performance, two sets of Online Effluent Analyzers were procured and commissioned in June 2017 at two ETP’s outlets at a cost of Rs 30.0/- Lakhs. The real time data transfer to CAC,TNPCB & CPCB is continuous. AIR ENVIRONMENT: Three number of AAQM stations namely CPCL East, ETP2 and CPP were replaced

by new set of instruments and a system with an operating system of Windows 7.0 to enhance the performance of data acquisition and real time data transfer to CAC

As per CPCB directives, CPCL has procured 19 sets of new stack analysers and commissioned the same. Further, connectivity of all the stack parameters to CPCB / TNPCB completed in October 2017.

VOC system commissioned in ETP2 is being operated continuously to ensure 90% removal hydrocarbons as per emission norms.

SOLID WASTE ENVIRONMENT: CPCL has ventured into in situ cleaning of tank bottom sludge through mechanical

cleaning. This method of sludge minimization and oil recovery, avoids handling of sludge and contamination of outside environment. The oil recovery is about 90% and the final sludge is very minimal.
