Sulfur Pelletizing Plants

CALIFORNIA SULPHUR CO.

BAY SULPHUR CO.
Port of Stockton, California
Cash & Associates provided structural and civil engineering for sulfur
pelletizing plants in Los Angeles Harbor and Port of Stockton. Work for the
California Sulphur Company Plant in Los Angeles Harbor (top photo) involved various
improvements to an existing plant while the Bay Sulphur Company plant in Stockton (middle
photo) involved design of a new facility. Each plant included approximately
2.5-acres that required the installation of special containment measures. A critical
component for both plants was design of special systems to collect, impound, treat and
recycle contaminated runoff. Systems include structures to direct contaminated
runoff to lined, reinforced concrete holding ponds that were specifically designed to hold
storm runoff for the site as well as process water from pelletizing operations. A
treatment system directs runoff based on flow. System components include a clarifier
to separate solids from liquids and a blending tank to neutralize the slightly acidic 
runoff via an automated caustic injection. Treated water is
recycled for use in plant operations.
Cash & Associates continues to provide on-call engineering services to California
Sulphur Co., Los Angeles Harbor plant. Recent work has involved installation of a
new pelletizer tower, new equipment, and other plant improvements.
