Units utilise a combination of long life filter elements and maintenance free vane packs, wire mesh or multi-cyclone mist extractor systems. Ultra high efficiency can be achieved. Differential pressure across clean elements is typically <0.1 bar. Elements are usually replaced when differential pressure reaches approximately 1 bar. Both vertical and horizontal configurations are available with vertical units used when available plot areas are limited. Quick and easy removal and replacement of filter elements can be achieved via optional quick opening closures. Vessels are built to any recognised construction codes and special standards, e.g. PD550, ASME, GOST, NACE etc. Materials of construction include carbon steel, stainless steel and corrosion resistant alloys. Units can be supplied as skid mounted packages complete with valves, piping and instrumentation. |
These units combine the principles of operation described for filters and separators. Filtration is achieved in the first compartment and separation is achieved in the second compartment. It should be noted that in the case of the filter separators the filter elements perform a dual function. They separate out solids but also serve to coalesce fine entrained liquid droplets in the feed gas. The coalesced droplets exit the filter elements via the element support tubes into the second compartment, where final liquid separation is achieved by the mist extractor system. |
