Technical details and manufacturing context for Collection Tank

Definition
The Collection Tank is a critical component of the Solvent Recovery Module, serving as the primary storage vessel for solvents that have been condensed and separated from waste streams. It functions as an intermediate holding container where recovered solvents accumulate before being transferred for purification, reuse, or disposal, ensuring continuous operation of the recovery process.
Working Principle
Condensed solvent vapors from the recovery unit are directed into the Collection Tank via piping. The tank maintains the collected liquid at ambient or controlled temperatures and pressures. Level sensors monitor fill levels to prevent overflows and trigger transfer pumps when capacity thresholds are reached. The tank may include agitation or mixing systems to maintain solvent homogeneity.
Common Materials
Stainless Steel 316L, Carbon Steel, Fiberglass Reinforced Plastic
Technical Parameters
  • Capacity of the collection tank, typically ranging from 50L to 10,000L depending on system throughput requirements (L) Customizable

Engineering Reasoning
0.1-2.0 bar gauge pressure, -20°C to 80°C temperature
Yield strength exceeded at 3.5 bar internal pressure or -40°C brittle fracture temperature
Design Rationale: Plastic deformation from hoop stress exceeding 316L stainless steel yield strength (205 MPa) or brittle fracture below ductile-to-brittle transition temperature
Risk Mitigation (FMEA)
Trigger Solvent-water azeotrope formation creating 1.8 bar vapor pressure at 95°C
Mode: Overpressure rupture at welded seam with 0.8 safety factor
Strategy: Pressure relief valve set at 2.4 bar with ASME Section VIII Div. 1 certification
Trigger Chlorinated solvent hydrolysis producing 50 ppm hydrochloric acid concentration
Mode: Pitting corrosion at 0.5 mm/year rate exceeding 3 mm wall thickness
Strategy: Duplex 2205 stainless steel construction with 3.2 mm minimum wall thickness per NACE MR0175

Application Fit & Sizing Matrix

Operational Limits
pressure: 0 to 10 bar (gauge)
flow rate: Up to 50 m³/h
temperature: -20°C to 150°C
slurry concentration: Up to 30% solids by weight
Media Compatibility

  • Maximum allowable working pressure (MAWP) of the system
  • Physical footprint constraints and connection port sizes

Reliability & Engineering Risk Analysis

Failure Mode & Root Cause
Corrosion-induced wall thinning
Cause: Chemical attack from stored fluids (acids, alkalis, or salts) combined with environmental moisture, leading to material degradation and loss of structural integrity.
Structural fatigue cracking
Cause: Cyclic loading from fluid sloshing, thermal expansion/contraction, or vibration from connected piping, resulting in stress concentration and crack propagation at weld joints or geometric discontinuities.
Maintenance Indicators
  • Visible weeping or leaks at seams, welds, or connections, indicating loss of containment integrity.
  • Abnormal audible vibrations or 'hammering' sounds during filling/emptying cycles, suggesting air entrapment, improper venting, or pump cavitation effects.
Engineering Tips
  • Implement a routine ultrasonic thickness testing program at high-risk corrosion areas (e.g., bottom plates, liquid-air interfaces) to monitor wall thickness trends and schedule proactive repairs before failure.
  • Install and maintain proper venting systems and anti-vortex baffles to minimize fluid turbulence, sloshing forces, and air ingestion, reducing cyclic stresses on tank structure and connected piping.

Compliance & Manufacturing Standards

Reference Standards
ISO 11439:2013 (Gas cylinders - High pressure cylinders for the on-board storage of natural gas as a fuel for automotive vehicles) ASME BPVC Section VIII (Boiler and Pressure Vessel Code - Rules for construction of pressure vessels) EN 13445-3:2021 (Unfired pressure vessels - Part 3: Design)
Manufacturing Precision
  • Wall thickness: +/-5% of nominal thickness
  • Out-of-roundness: 1% of nominal diameter
Quality Inspection
  • Hydrostatic pressure test (1.5x design pressure for 30 minutes)
  • Visual and dimensional inspection per ASME BPVC Section V
