ABSTRACT:
An elongated tubular natural gas filtering vessel (12) has a plurality of longitudinal tubular filter elements (28) mounted therein by mounting means (44,68,70) which enables lateral displacement of filter elements (28) for longitudinal removal through a forward access port (18) of reduced diameter. A mast structure (44) mounts the filter elements (28) in a matrix array, including perimeteral filter elements (28) not aligned with the access port (18). A central mast (46) is rigidly mounted to the vessel (12) interior, and has a plurality of cross-bars (50) supported thereon. Each cross-bar (50) supports one row in the matrix array. The mast (46) has a plurality of forwardly extending ledges (48) between which are mounted a plurality of latching wrenches (60) with eccentric camming surfaces (64) for releasably locking in place a row of filter elements (28). A superstructure (68,70) is mounted to the mast structure (44) for securing the cross-bars (50) against lateral movement relative to one another. One or more aligned filter elements (28) is longitudinally forwardly removed through the access port (18) followed by lateral displacement of non-aligned filter elements (28) and then removal of the latter through the access port (18). A significant cost reduction in the removable closure head (32) for the access port (18) is realized. Furthermore, servicing time and manpower for removal and replacement of filter elements (28) is drastically reduced.
