A Pennsalt guide explains to interested visitors how caustic-chlorine is created during Pennsalt's 100th anniversary open house. Despite its name, Pennsalt does not produce ordinary table salt. It does, however, produce caustic and chlorine from coarse gray California salt for pulp mills. Brine flows into cylinders and caustic soda drains off at the bottom with chlorine gas emerging from the top. These chemical products are then shipped back to California by tanker for a profit.
