Industrial liquid filtration for removal of solid particles from a liquid process
Winston/Royal Guard Type 61V Vertical Liquid Filters remove solid contaminants from various liquid process streams in refining, chemical, petrochemical, oil and gas, and other industries. Liquid process filtration applications vary widely and a variety of liquid filter cartridges including materials and particle retention sizes are available.
Particulate filtration applications for industrial liquid filters include light hydrocarbons, acids, alkalies, process water, glycols, amines, and many other process and finished product liquids. These liquid filters may be used for removing solid contaminants from injection well water to refinery filter applications.
Filter Cartridges are available in a variety of types and styles so as to meet stringent application requirements for liquid process filtration. Some examples of filter types are:
- Wound fiber depth style cartridges available with media in cotton, fiberglass, nylon, acrylic/orlon, polyester, polypropylene and Rayon. Particle retention sizes are 0.5, 1, 3, 5, 15, 20, 25, 30, and up to 200 microns.
- Melt blown liquid filter cartridges for high viscosity liquids made of polyester and acrylic fibers in a depth style configuration. Retentions sizes are 2, 5, 10, 25 50, 75, 125, and 150 microns. Maximum liquid temperature is 250 ⁰ F.
- Pleated cartridges with a large surface area for trapping high amounts of solid contaminants are typically polypropylene with core and cap material in tinned steel, 304 stainless, or 316 stainless steel. These liquid filter cartridges are widely used and compatible with a range of chemicals. Absolute micron ratings are 1, 2, 5, 10, 15, 20, 40, and 70. Standard efficiency is 99% with 99.98% available.
Particulate filtration is recommended to be provided upstream of activated carbon filters to prevent solids from contaminating the carbon, and downstream to catch any carbon fines carryover.
