Red River designs and fabricates ASME code separators and gas scrubbers for oil production operations across the United States. These vessels split the produced wellstream into gas, oil, and water, and remove entrained liquids and solids from gas streams before compression, dehydration, or sale. Every unit is engineered to ASME Section VIII, Division 1 and built for dependable service in upstream and midstream facilities.

ASME Separators for Oil and Gas Production

Production separators divide the incoming wellstream into its separate phases so each can be measured, treated, and moved downstream. Red River builds two-phase separators that split gas from liquid, and three-phase separators that split gas, oil, and water in a single vessel. Each separator is fabricated to the ASME Boiler and Pressure Vessel Code, Section VIII, Division 1, and sized to your flow rate, design pressure, and separation requirements.

Key Features

ASME code construction, U Stamp certified with National Board registration available

Two-phase and three-phase configurations

Horizontal and vertical orientations to match your facility layout

Internal components including inlet diverters, mist extractors, and weirs

Engineered to your design pressure in psig and operating temperature

Gas Scrubbers for Oil Production Facilities

A gas scrubber is a separator built for streams with a high gas-to-liquid ratio, designed to pull entrained liquid droplets and solid particles out of a gas flow. Red River fabricates inlet scrubbers, fuel gas scrubbers, and compressor suction and discharge scrubbers that protect downstream equipment from carryover. Clean gas into a compressor or dehydration unit means fewer failures, less maintenance, and steadier production.

Key Features

Custom ASME-Rated
Separators and Scrubbers

Every production facility has its own pressures, fluid properties, and space constraints, so Red River builds each vessel to your specification rather than from a fixed catalog. Our engineering team works from your process data to set diameter, seam-to-seam length, nozzle schedule, and internals. This is the same custom pressure vessel capability that serves operators from single-well sites to full central processing facilities.

Custom Options

Applications of Separators and Scrubbers in Oil Production

Separators and scrubbers appear at nearly every stage of the production process, from the wellhead to the sales point. Red River fabricates vessels for both single-unit replacements and full facility build-outs.

Common Use Cases

Wellhead and test separation

Two-phase and three-phase production separation

Inlet gas scrubbing ahead of compression

Fuel gas conditioning and scrubbing

Compressor suction and discharge protection

Slug catching and liquids knockout

Red River Fabrication Process for Separators and Scrubbers

1

Requirement Analysis

We review your process conditions, fluid composition, flow rates, design pressure, and any sour service or regulatory requirements.

2

Engineering and Design

Our team drafts a code-compliant design with sizing calculations and internal selection. You approve drawings before any steel is cut.

3

Fabrication and Quality Control

Cutting, forming, welding, and assembly are performed to ASME and AWS standards. Nondestructive examination is coordinated to meet code and project requirements, and each vessel is inspected by an ASME Authorized Inspector.

4

Delivery and Documentation

Every vessel ships with material test reports, quality control records, and the full data package, delivered coast to coast by direct heavy-haul freight.

Key Takeaways

FAQs About Oil Production Separators and Scrubbers

What is the difference between a separator and a scrubber in oil production?

A separator handles streams with significant amounts of liquid and gas, splitting them into distinct phases. A scrubber is a lighter-duty separator built for streams that are mostly gas, where the job is to remove small amounts of entrained liquid and solids. Both share the same code basis but differ in sizing and internals.

Yes. Red River fabricates separators and scrubbers to ASME Section VIII, Division 1, and holds the ASME U Stamp. National Board registration is available on request, and every vessel is inspected by an ASME Authorized Inspector before it ships.

A two-phase separator splits the wellstream into gas and liquid. A three-phase separator goes further and splits the stream into gas, oil, and water within a single vessel. The right choice depends on your fluid composition and how you handle produced water.

Yes. Red River can fabricate vessels for H2S environments using materials and welding procedures aligned to NACE MR0175. Sour service requirements are confirmed during the requirement analysis stage so the design matches your field conditions.

Each vessel is delivered with material test reports, quality control records, and a complete data package documenting code compliance. This traceability supports your own inspection, permitting, and audit requirements.
