Abstract: An apparatus for mounting a scrubber pressure vessel to a base. The scrubber has a skirt which is mounted directly onto the base. The base has two orthogonal longitudinal beams. The beams are oriented with respect to the pressure vessel such that the forces directed to the scrubber by its attached piping are parallel to one of the beams. The skirt is attached to the base on the longitudinal axes and the connections may vary in stiffness such that the natural frequencies of the system along both axes can be adjusted to avoid the operating frequency which would otherwise result in resonance.
