Abstract:
1. A reactor apparatus comprising: (a) a vessel comprising (x) or (y): (x) a single shell member the shell member having a circumferential wall with an inner surface which defines an interior cavity within the inner surface; the shell member having a top shell member opening at a top of the circumferential wall and a bottom shell member opening at a bottom of the circumferential wall, a first flange integrally formed with the shell member around the circumferential wall at the top shell member opening, wherein the first flange extends outwardly perpendicularly from the circumferential wall; a second flange integrally formed with the shell member around the circumferential wall at the bottom shell member opening, wherein the second flange extends outwardly perpendicularly from the circumferential wall; (y) a plurality of sequentially attached shell members, each shell member having a circumferential wall with an inner surface which defines an interior cavity within the inner surface; each shell member having a top shell member opening at a top of the circumferential wall and a bottom shell member opening at a bottom of the circumferential wall, a first flange integrally formed with the shell member around the circumferential wall at the top shell member opening, wherein the first flange extends outwardly perpendicularly from the circumferential wall; a second flange integrally formed with the shell member around the circumferential wall at the bottom shell member opening, wherein the second flange extends outwardly perpendicularly from the circumferential wall; the shell members being sequentially attached by mating adjacent shell member flanges with an array of bolt and washer combinations extending around and through the adjacent shell member flanges; an intermediate gasket being positioned between mating adjacent shell member flanges, each intermediate gasket being positioned between the circumferential wall to the circular array of bolt and washer combinations; the vessel having a top opening at a top end thereof which is an uppermost top shell member opening, and a bottom opening at a bottom end thereof which is a lowermost bottom shell member opening; (b) a loose fluoropolymer liner lining the entire inner surface of each circumferential wall; (c) a top cover on the entire top opening of the vessel and on an uppermost of the shell member flanges, wherein the top cover has an inner surface positioned on a first gasket, the first gasket being positioned on the uppermost shell member flange and the first gasket being separated from the uppermost shell member flange by a first end of the liner; the top cover being attached to the uppermost shell member flange by a circular array of bolt and washer combinations extending around and through both the top cover and the uppermost shell member flange, the circular array of bolt and washer combinations being positioned between the circumferential wall and a terminal edge of the uppermost shell member flange; the first gasket being positioned between the circumferential wall to the circular array of bolt and washer combinations; (d) a bottom cover on the entire bottom opening of the vessel and on a lowermost of the shell member flanges, wherein the bottom cover has an inner surface positioned on a second gasket, the second gasket being positioned on the lowermost shell member flange and the second gasket being separated from the lowermost shell member flange by a second end of the liner; the bottom cover being attached to the lowermost shell member flange by a circular array of bolt and washer combinations extending around and through both the bottom cover and the lowermost shell member flange, the circular array of bolt and washer combinations being positioned between the circumferential wall and a terminal edge of the lowermost shell member flange; the second gasket being positioned between the circumferential wall to the circular array of bolt and washer combinations; (e) a first end of the liner being attached to the uppermost shell member flange by a circular array of screw fasteners extending around and through the uppermost shell member flange, wherein the fasteners are positioned between the circular array of bolt and washer combinations and the terminal edge of the uppermost shell member flange; and a second end of the liner being attached to the lowermost shell member flange by a circular array of screw fasteners extending around and through the lowermost shell member flange positioned between the circular array of bolt and washer combinations and a terminal edge of the lowermost shell member flange; (f) at least one inlet for supplying at least one fluid into the interior cavity; (g) at least one outlet for discharging at least one fluid from the interior cavity; (h) wherein at least one shell further comprises at least one weep hole capable of transmitting gases from between the interior cavity of the vessel and the liner to the outside of the vessel, and (i) wherein the at least one weep hole further comprises at least one fluoropolymer insert which extends through the weep hole and into the vessel.
