PTFE Lined Acid Resistant Chemical Receiver Vessel

PTFE Lined Acid Resistant Chemical Receiver Vessel belongs to process-side intermediate buffer equipment, specially optimized for acidic fluid receiving working conditions, different from general-purpose multi-media receiving tanks and large static storage tanks. It is installed at outlet positions of acid distillation columns, acid reactors and condensation units, for instant collection of hot acidic condensate and reaction discharge liquid.

Hot acidic condensate brings both temperature impact and acid erosion risk; ordinary metal receivers will suffer rapid corrosion, while common plastic containers cannot bear process vacuum and high-temperature condensate shock. This receiver combines pressure-resistant carbon-steel shell and seamless full-wrapped PTFE inner lining, effectively coping with periodic inflow of hot acid liquid.

Widely deployed in acid synthesis, pickling waste-acid recovery and fluorochemical condensation-recovery production lines for overseas chemical plants.

What is PTFE Lined Acid Resistant Chemical Receiver Vessel？

PTFE Lined Acid Resistant Chemical Receiver Vessel is a pressure-bearing intermediate buffer vessel dedicated for acidic chemical process loops. It consists of carbon-steel pressure-resistant outer shell and vacuum-laminated seamless PTFE inner lining covering tank cavity, manhole and all connecting nozzles. Its core function is transient receiving and short-time buffering of hot acidic condensate and process discharge liquid coming from upstream reactors or distillation columns, before transferring medium to subsequent storage or treatment units. It is not used for long-term static stockpiling or chemical stirring reaction. Equipped with dedicated nozzles for condensate inlet, liquid-level monitoring, vacuum balancing and acid-liquid outlet. Available in vertical and horizontal structural forms, and connects with PTFE-lined acid-resistant piping system via HG20536 anti-corrosion flanges.

Core Product Advantages

1. Target-Oriented Anti-Corrosion For Hot Acid Condensate Full-area PTFE lining resists scouring and erosion caused by periodically incoming hot acidic condensate, solves premature failure problem of metal receivers under alternating hot acid impact.

2. Vacuum-Balanced Process Adaptation Stable performance under process micro-negative-pressure working status, matches vacuum distillation acid-condensate collection workflow, avoids lining delamination under periodic pressure fluctuation.

3. Multi-Nozzle Customized For Acid-Process Loop Pre-reserved functional nozzles for condensate inlet, liquid-level gauge, vacuum balance and acid-liquid discharge. No extra on-site hole-opening needed, preventing lining damage caused by secondary processing.

4. Low-Residue Inner Surface For Acid-Batch Switching Smooth non-stick PTFE inner wall reduces acidic medium residue, convenient for flushing when switching different acid batches, lowers cross-contamination risk between different acid-type production cycles.

5. Dual Installation Form Options Vertical compact type for platform-mount above equipment; horizontal saddle-supported version for limited-height workshop space, flexible adaptation to upstream-downstream pipeline layout.

6. Unified Anti-Corrosion Interface Compatibility HG20536 full-PTFE-lined flange standard, seamless docking with Zhuoyan acid-resistant lined reactor, distillation column, pipeline and fittings for complete acid-process one-stop procurement.

Main Application Fields

Mainly applied in process buffer links of acid-related chemical production, with overseas delivery records for Southeast-Asia and Middle-East inorganic-chemical plants:

Inorganic-acid distillation line: Condensate receiving for hydrochloric acid, nitric acid rectification process

Fluorochemical plant: Hot hydrofluoric-acid-containing condensate temporary buffering

Pickling-waste-acid recovery project: Receiving of waste acid effluent from pickling workshop

Fine-chemical acid synthesis: Short-term buffering of acidic reaction discharge liquid

Environmental-protection corrosive waste-liquid treatment: Front-end receiving of concentrated acidic waste-water

Pilot-scale acid-process test workshop: Intermediate collection for small-batch acidic pilot reaction

Standard Production Process

1. Carbon-steel shell integral welding, full polishing for tank inner cavity and all nozzle weld seams to eliminate sharp corners.

2. 500 ℃ high-temperature degreasing to remove welding residual stress, prevent lining deformation under periodic hot-acid impact.

3. Sa2.5 grade heavy sandblasting for inner cavity surface, guarantee high adhesive strength for PTFE sheet.

4. Sodium-activation treatment of imported PTFE raw sheet; vacuum seamless lamination inside 10 000-grade clean workshop. Double PFA hot-melt welding for all nozzle transition corners which bear acid condensate scouring.

5. Full-wall mobile 10 KV spark scanning inspection, focus detection on nozzle-tank-body joint positions vulnerable to acid penetration.

6. 1.2-times design-pressure hydraulic holding test, keep pressure 30 minutes without pressure drop.

7. Inner-cavity cleaning to remove workshop dust; every flange opening sealed by dedicated PTFE anti-scratch protective caps. Reinforced wooden-case packaging for sea-land transportation.

FAQ

Q1: Can this PTFE Lined Acid Resistant Chemical Receiver Vessel collect hot hydrofluoric-acid-containing condensate? A: It can work for HF-containing hot condensate when upgraded to 3 mm thickened PTFE lining, please inform condensate composition before ordering.

Q2: What installation options are available for this acid-process receiver vessel? A: Vertical compact type for equipment-platform mounting; horizontal saddle-supported version for low-height-restricted workshop layout.

Q3: Is on-site drilling allowed to add extra nozzles after delivery? A: On-site drilling or cutting is strictly forbidden, which will destroy integral PTFE lining; confirm all nozzle positions in pre-production drawing stage.

Q4: Can this receiver vessel match existing acid-resistant distillation-column and lined piping? A: It adopts HG20536 unified anti-corrosion flange standard, can directly dock with our full-series acid-resistant fluorine-lined process equipment and pipe fittings.

Q5: What inspections will each receiver vessel pass before shipment? A: Every unit undergoes full-wall spark scanning (emphasis for nozzle joints) plus hydraulic pressure holding tightness double-test.

Q6: What does the official warranty cover? A: Carbon-steel shell 10-year structural warranty; PTFE lining 5-year warranty (exclude artificial scratch, impact and mis-operation damage); nozzles and accessories 2-year warranty.
