Work Detail

Construction Works For Plants, Mining And Manufacturing And For Buildings Relating To The Oil And Gas Industry – Kommunale Energieverutilierung Schwaben Gku, Sewage Sludge Upcycling Plant, Sewage Sludge Pyrolysis Plant. The Schwaben Municipal Energy Utilization Gku Would Like To Build A Production Hall Including An Administration Building For Sewage Sludge Drying With Pyrolysis In The Immediate Vicinity Of The Sewage Treatment Plant In Buchloe For The Sustainable Preparation/Further Processing Of Sewage Sludge (From The Companys Own Sewage Treatment Plants). The Subject Of The Tender Is The Construction Of A Sewage Sludge Pyrolysis Plant Including Engineering. In Addition, Inspection, Maintenance And Repair Of The System Are Commissioned. The Process Is A Continuously Operating, Self-Contained System For Recycling Dried Sewage Sludge. The Pre-Dried Sludge Is Controlled Using Suitable Conveyor Technology And Fed Into The System In An Airtight Manner. In The Reactor, The Material Is Thermally Treated At Temperatures Of Around 500 To 750 °C With The Extensive Exclusion Of Oxygen. This Creates A Solid Carbonate, Which Consists Partly Of Remaining Organic Carbon Compounds And Mineral Components. The Material Utilization Of This Carbonate Is One Of The Goals Of The Process. The Carbonate Is Discharged From The System Using Suitable Conveyor Technology And Cooled In A Controlled Manner To Ensure Safe Storage And Avoid The Risk Of A Dust Explosion. Storage Usually Takes Place In Big Bags, Which Enable Easy Handling And Transport. At The Same Time, This Process Reliably Destroys Organic Pollutants - Such As Microplastics Or Pfas. The Resulting Combustible Gases Are Filtered And Then Burned Completely And With Low Levels Of Pollutants In A Downstream High-Temperature Combustion Chamber (Around 950 To 1050 °C). The Resulting Thermal Energy Is A By-Product And Can Be Used, For Example, To Dry Sewage Sludge. Additional Exhaust Gas Purification Measures - Such As Dust Separators, Gas Scrubbers Or Activated Carbon Filters - Ensure That Emissions Such As Dust, Nitrogen Oxides (Nox), Sulfur Dioxide (So2) And Heavy Metals Are Effectively Reduced. A Continuous Negative Pressure System Ensures That No Process Or Exhaust Gases Can Escape Uncontrollably. Requirements For Pyrolysis: A. Reactor System: Designed As A Reactor System With Continuous And Fully Automated Process Control. Batch Or Semi-Batch Operations Are Not Permitted. B. Separation Of Pyrolysis And Oxidation: The System Must Ensure A Clear Separation Of The Pyrolysis And Oxidation Processes In Order To Enable Optimal And Controllable Process Control (Temperature And Residence Time). The Material Must Be Heated Indirectly. C. Heat Recovery/Energy Efficiency: Use Of The Exhaust Gases From The Oxidation Of The Pyrolysis Gases To Return Heat To The Reactor In Order To Minimize The Thermal Energy Consumption Of The Entire System. Electrical Heating Of The Reactor Is Not Permitted. D. Control: The Control Is Carried Out Via A State-Of-The-Art Automation System
