Pressure vessels for gas and liquid treatment

In a gas stream there are two things to separate: solids—particles, rust, fine sand—and liquids carried as aerosols—water, oil, fuel, condensed hydrocarbons. We design a vessel for each: the filter housing, which holds cartridges to retain particles, and the coalescer vessel, which merges the aerosols into droplets and drains them from the bottom.

Both are built in carbon steel at our metal fabrication plant and sized for each process to ASME VIII Division 1, API, NACE and PED 97/23/EC: single-element or multi-element depending on the flow rate, in a vertical or horizontal configuration, with a quick-opening or bolted closure. Each unit ships with design calculations, detailed engineering with a 3D drawing, material and welder certificates, and a hydrostatic test.

We also manufacture the cartridges for particle filtration: ProFlow, in pleated polypropylene, and MicroFiber, in glass microfiber. They are in the prefiltration category.

Three vessels for process liquids. The filter housing holds cartridges that retain solid particles. The liquid-liquid separator holds the elements that separate one liquid from another, such as water entrained in a hydrocarbon. And the SteelFlow CCA basket strainer retains solids in a stainless steel basket, made of perforated plate or mesh, that is washed and reused.

All three are built in carbon steel at our metal fabrication plant. The housings are sized for the process flow rate to ASME VIII Division 1, API, NACE and PED 97/23/EC, for low, medium and high pressure, and the SteelFlow CCA to ASME VIII Division 1. All of them ship with design calculations, detailed engineering with a 3D drawing, material and welder certificates, and a hydrostatic test.

For high flow rates, the SaniFlow HF housing, in AISI 304 or 316L stainless steel, holds 6″ High Flow cartridges: injection water, brines, and chemicals and petrochemicals compatible with the cartridge, at 17 to 250 m³/h recommended per housing. And for high solids loads, the SaniFlow STE-G, also in stainless steel (AISI 304), holds one or three 7″ filter bags: the solids stay in the bag and leave with it at changeout.

We also manufacture the cartridges for particle filtration: ProFlow, in pleated polypropylene, and MicroFiber, in glass microfiber. They are in the prefiltration category.
