Type DST, Horizontal Flow Separators (Reliable Gas Liquid Separators)

Didion Separator, a subsidiary of Didion’s Mechanical, is a major company in the field of oil and gas separation technology. Our application knowledge, combined with innovative design technologies and excellent fabrication methods has made us a leading choice for industrial customers when it comes to gas liquid separators.

Our type DST separator is a horizontal in-line gas liquid separators designed to produce contaminant free gas and steam. The DST separator has the capability to remove 99% of entrained solids that are 10 microns in size or larger. It is also excellent for gas flows with a high percentage of entrained liquid. Because of the greater capacity to handle liquids in horizontal flows, Type DST separators are often chosen over the Type DSL separator. Please keep in mind though that Type DSL separators are less expensive. We would be happy to assist you in selecting which model is best for your gas flow in order for you to get most effective model, while at the same time make the best use of your funds.

Features of Didion Separator Type DST, Horizontal Flow Separators

  • They are capable of removing 99% entrainment sizing 10 microns from air, steam, and gas processes. Our custom designs can provide better efficiencies.
  • Internal elements are made from stainless steel to provide resistance to corrosion.
  • The internal elements are self-cleaning, which minimizes maintenance. This ensures maintained efficiencies unlike vane or chevron style separators.
  • Carbon steel is used to manufacture flanges, nozzles, and couplings.
  • Standard 150# units can accommodate design pressures up to 150 psig at 500° F.
  • Standard 300# units can accommodate design pressures up to 500 psig @ 650° F.
  • Corrosion allowance of 1/16” ensures many years of service.
  • We can provide custom designed separators to handle your unique flows and efficiency requirements. The separators can also be custom manufactured using a variety of alloys.
  • As a family owned and ASME certified Fabrication Company, we provide quality products and services beyond your expectation.

We understand that every customer’s product needs are unique. For this reason, we also take on customized requirements. We work with you to design and manufacture separators with exacting specifications for specialized industry applications.

At Didion’s Mechanical, We are proud to say that we can certify our vessels and separators to the following global standards:

  • ASME Section VIII, Div. I, Div. II, and Div. III
  • U
  • U2
  • U3
  • S (Power Boilers of ASME Section I)
  • PP (Pressure piping of ASME Section I& B31.1)
  • R (National Board Stamp for Repairs and Alterations)
  • CE (European Pressure Equipment Directive)


The design of our gas liquid separators allows for easy installation and operation in steam distribution lines and system gas pipelines. They can also be used to protect expensive industrial equipment, such as:

  • Turbines
  • Sulfur Condensers
  • Reactors
  • Heat Exchangers
  • Intercooler and After cooler Equipment
  • Scrubbing Systems
  • Gas Well Heads
