Sour Service Slug Catcher With isolated Sludge Manifold For Clean-out

At high pressure and in sour service, ZHM’s unique extrusion process allowed the use of high strength low alloy carbon steel fabrication, saving time and money. This Slug Catcher also included an isolated sludge manifold to aid in clean-out.

Design: (2) 6 – finger Slug Catchers

Gas Flow Rate: 740 MMSCFD (million standard cubic feet per day equal to 20.95 million m³/day), indicating high throughput.

Storage Capacity: 14,500 barrels (likely total 2,305 cubic meters (m³)), accommodating liquid slugs and ensuring stable downstream processing.

Design Pressure: 2,103 psig or 14.5 MPa (megapascals), necessitating robust materials and construction.

Specials: Sour Service

Line Pipe: 42” API 5L Line Pipe

The Slug Catcher project in Vietnam is a sophisticated engineering solution tailored for high-pressure, sour service conditions, integrating advanced materials and design efficiencies. Here's a structured breakdown:

Key Components & Specifications

Design Configuration:

Two 6-Finger Units: Each "finger" acts as a separation vessel, enhancing liquid-gas separation efficiency. The dual units provide redundancy and capacity to handle fluctuating flow rates, ensuring continuous operation.

Material Innovation:

HSLA Carbon Steel: High-strength low-alloy steel offers strength-to-weight advantages, reducing material costs and fabrication complexity. Typically challenging in sour service due to H2S-induced cracking, but mitigated here by:

Unique Extrusion Process: Enhances microstructural integrity, improving resistance to sulfide stress cracking (SSC). This allows substitution of costlier alloys (e.g., stainless steel) with HSLA, aligning with NACE MR0175 standards for sour environments.

Sour Service Considerations:

H2S Resistance: The extrusion process ensures uniform grain structure and surface quality, critical for preventing SSC. Welding and fabrication protocols likely adhere to strict NACE guidelines to maintain integrity.

Special Features:

Isolated Sludge Manifold: Facilitates sludge (solids, sand) removal without system shutdown, minimizing downtime and maintenance costs. Critical for operational efficiency in high-flow systems.

Logistical & Environmental Context:

Location: Vietnam’s humid, potentially corrosive coastal environment necessitates additional anti-corrosion measures, though the design focuses primarily on sour service challenges.
