  1. Green Productivity for SOY OIL PROCESSING INDUSTRY A Case study Presented by- Indian Group

  2. Team • Production manager To lead the team and assign responsibilities • Health and Safety officer  advising on health/safety • QA/QC representatives  Advice on quality production • Production Engineer Feasibility of processes, optimisation and financial aspects • R&D rep.  technological issues, ways to improve productivity • Environmental Engineers  For the assessment of environmental impacts

  3. Spilled seed Dust PROCESS FLOW DIAGRAM Seed unloading and cleaning section: Soybean seed supply Storage in day silos Lab Testing Discarded seed Transfer (Bucket elevator & Redler conveyor) Unloading Dust Transfer (Bucket elevator & Redler conveyor) Storage in storage silos Spilled seed Dust

  4. Spilled seed Spilled seed Dust Dust Spilled seed Stones& mud balls Condensate Spilling Spilled seed & leftovers Dust Preparatory section: Seeds from day silos To Solvent Extraction Plant Transfer (Bucket elevator & Redler conveyor) Heat/ Dry air Dryer Moisture Secondary Screening Flaking in Flaker De-stoning Spilling Steam Conditioning in cookers Cracking of seed

  5. SEP Dried Flakes Hexane Steam Hot Air condenses Hexane Hexane Vapours Oversized lumps Accepted Size Water Hexane Drained out Packing

  6. Major Waste Streams or Area of Losses • 1. Dust, husk, traces, mudball and stones due to • removal from received seed • 2. Leakage of Hexane vapours due to • drying of DOC • dissolving in steam and water • leakage in different compartment • incomplete retrieval from mineral oil • evaporation losses and vent losses

  7. 3. Mineral oil wastages due to • inadequate recycling process • 4. Crude oil losses due to • Retention in DOC • Leakages during transportation and storage • Insufficient cooking and flaking

  8. 5. Energy losses due to • Inefficiency in conversion and transportation of steam • Poor quality of coal • Obsolete technologies • Poor maintenance

  9. Fishbone Diagram for Hexane Loss

  10. Fish bone diagram:

  11. 1. Dust, Husk, traces, mud balls and stones Personal Protective Equipments Procurements of better quality seeds Proper ventilation and disposal arrangements 2. Leakages of Hexane Proper housekeeping and maintenance of equipments Procurements of high quality hexane Change in technology - using mechanical extraction - Methanol+ NaOH Recovery from mineral oil Green Productivity Option

  12. 3. Energy losses Good quality coal Adoption of more efficient technologies Proper thermal insulation Good maintenance of equipments Efficient heat recovery systems

  13. 4. Oil losses Proper house keeping and maintenance of equipments Sealing of leakages sufficient cooking flaks Use of high quality seeds & hexane Appropriate temp. control and monitoring

  14. 5. High inventory costs Proper estimation of requirements Proper and adequate storage arrangements for seeds 6. Waste water generation and water losses Adequate capacity & efficient ETP

  15. 7. Health hazards Proper handling tools and equipments Personal protective equipments Spreading health and safety awareness programmes Utilisation and disposal of ash

  16. GP Objectives & Targets

  17. GP Policy For The Plant • We at Rama Phosphates Ltd will strive as an organization to reduce the level of hexane wastage as it will lead to better productivity and work towards our aim of sustainable development by conserving natural resources. • In order to achieve this, we aim to practice: • To meet relevant environmental legislation • To prevent pollution, reduce waste and resource consumption, encourage recovery & recycling as opposed to disposal, where feasible • To introduce state of the technology to enhance plant efficiency and reduce losses • To ensure proper health & safety working environment for all employees
