Technical details and manufacturing context for Gas Cleaning Plant

Definition
A critical component within the Integrated Blast Furnace and Basic Oxygen Furnace Steelmaking System responsible for cleaning and conditioning the hot, dust-laden gas produced by the blast furnace. It removes particulate matter (dust), cools the gas, and may adjust its composition to make it suitable for reuse as fuel in other plant processes (e.g., heating stoves, power generation) or for safe release, thereby recovering energy and reducing emissions.
Working Principle
Hot, raw blast furnace gas is first cooled, typically in a spray cooler or waste heat boiler. The cooled gas then passes through a series of cleaning stages, which may include cyclones for coarse dust removal, followed by wet scrubbers (e.g., venturi scrubbers) or electrostatic precipitators (ESPs) for fine particulate removal. The cleaned gas is then often dehydrated and its pressure boosted before being sent to the plant gas network.
Common Materials
Carbon steel, Refractory linings, Stainless steel (for corrosive zones)
Technical Parameters
  • Design gas flow capacity (Nm³/h) Per Request
Components / BOM
  • Gas Cooler
    Reduces the temperature of the hot raw gas, often recovering waste heat.
    Material: Carbon steel with refractory lining
  • Cyclone Separator
    Removes coarse dust particles from the gas stream using centrifugal force.
    Material: Carbon steel
  • Venturi Scrubber
    A wet scrubbing unit that uses high-velocity gas to atomize water, capturing fine dust via impaction.
    Material: Carbon steel / Stainless steel
  • Demister/Mist Eliminator
    Removes entrained water droplets from the gas after wet scrubbing.
    Material: Polypropylene / Stainless steel
Engineering Reasoning
0.8-1.2 bar inlet pressure, 0.5-0.8 bar outlet pressure, 150-250°C operating temperature
Inlet pressure <0.5 bar causes flow reversal, outlet pressure >1.5 bar ruptures bag filters, temperature >280°C melts PTFE filter media
Design Rationale: Pressure differential collapse across venturi scrubbers at ΔP<0.3 bar, thermal degradation of polypropylene demisters above 120°C, sulfuric acid dew point corrosion at 120-150°C with H2S>200 ppm
Risk Mitigation (FMEA)
Trigger Cyclic thermal stress from 150-250°C temperature swings during BF gas surges
Mode: Thermal fatigue cracking in quench tower refractory lining
Strategy: Install silicon carbide refractory with 0.8 W/m·K thermal conductivity and 4.5×10^-6 /°C expansion coefficient
Trigger Ammonium chloride deposition from NH3>50 ppm and HCl>20 ppm at 120-180°C
Mode: Flow restriction and pressure drop increase to ΔP>1.0 bar across electrostatic precipitator
Strategy: Maintain gas temperature above 180°C through preheater with 2.5 MW capacity and install soot blowers at 40 bar steam pressure

Reliability & Engineering Risk Analysis

Failure Mode & Root Cause
Corrosion-induced thinning
Cause: Exposure to acidic gases (e.g., SOx, NOx) and moisture forming corrosive acids, accelerated by high temperatures and inadequate material selection.
Fouling and plugging
Cause: Accumulation of particulates, tars, or salts in scrubbers, ducts, or mist eliminators due to insufficient cleaning, poor gas velocity control, or inadequate filtration upstream.
Maintenance Indicators
  • Unusual increase in system pressure drop across scrubbers or filters, indicating flow restriction.
  • Visible leaks, discoloration, or weeping at welds and joints, especially in wet scrubbing sections.
Engineering Tips
  • Implement real-time corrosion monitoring (e.g., corrosion coupons, ultrasonic thickness testing) at critical zones and upgrade materials to high-alloy steels or linings where needed.
  • Optimize preventive cleaning schedules for internals using automated sootblowing or chemical cleaning, and ensure proper upstream particulate removal to reduce fouling load.
