Claim:
A chemical loading system for loading a molten chemical into a tanker, the chemical loading system comprising: a source for supplying the molten chemical to the tanker; a stationary feed line for supplying the molten chemical from the source; a heating jacket mounted to the stationary feed line, the heating jacket adapted for carrying a heating fluid to keep the molten chemical from solidifying in the stationary feed line; an extendable loader assembly having a feed passage in fluid communication with the stationary feed line, the extendable loader assembly having a retracted position and an extended position relative to the stationary feed line, the feed passage being adapted to have at least a portion thereof inside the tanker when the extendable loader assembly is in the extended position; feed seals positioned between the stationary feed line and the feed passage; metal plates positioned between the stationary feed line and the feed passage, wherein the metal plates are adapted to protect the feed seals from the molten chemical; and a hoist assembly that selectively extends and retracts the extendable loader assembly between the retracted and extended positions.
