CHEMICAL STORAGE AND BLENDING SYSTEMS
CrownTowers Chemical Co.
COMPREHENSIVE
SOLUTIONS FOR UNLOADING, STORING, TRANSFERRING, BLENDING AND CONDITIONING RAW
MATERIALS
Crown Towers –Chem storage and
blending solutions are available in a range of types, sizes and modular
configurations. Our design engineers work with customers to determine the best
combination of storage and blending equipment to satisfy their unique chemical
and production requirements.
Bulk chemical storage systems unload,
store and transfer intermediate to large quantities of raw materials within a
closed loop, minimizing opportunities for contamination, spills, evaporation
and employee or environmental exposure.
Blending systems allow in-house
formulation of liquid or liquid and solid particle blends to achieve the
specific characteristics of a product. Polyols typically require the addition
of blowing agents, activators, emulsifiers, foam stabilizers, flame-retardants
or other auxiliary materials to achieve those characteristics.
Bulk storage systems for larger
volumes of chemicals include unloading stations for materials delivered by
tanker truck or rail car, storage tanks, transfer pumps and all required
controls, valves, instrumentation, safety devices and piping.
SPECIALIZED BULK SYSTEMS FOR FLAMMABLE MATERIALS
Crown
Towers Chemicals Co experts have the know-how for safe processing of the
eco-friendly blowing agent pentane. Because pentane can create an explosive
atmosphere, at certain gas concentrations our Pentane Process Technology (PPT)
comprises a catalogue of primary and secondary safety measures to prevent
emergence of explosive mixes right from the start. Our years of global
experience with these systems means we can offer you a suitable concept that
complies with national and international directives as well as local
regulations and requirements.
BLENDING SYSTEMS FOR LIQUIDS AND POWDERS
Blending
systems precisely meter and blend various additive into the main polyol stream
to improve both mixing ability and reaction behavior. Crown –Chem offers proven
equipment for conditioning, blending and mixing raw materials with the polyol
stream, including static or dynamic mixers and integrated gas loading units.
BULK UNLOAD STATIONS WITH PUMP OR PRESSURE TRANSFER
Bulk
unload stations are designed for safe, efficient unloading of liquid raw
materials delivered by tanker truck or rail car.
The
delivery tanker begins unloading chemicals by connecting to pipe couplings and
valves mounted in an unload station box. For high viscosity chemicals or longer
distances, unload pumps move the chemical from delivery tanker to the bulk
storage tank. For short distances and low viscosity materials, a pressure
transfer method may be used. A blanket of dry air or nitrogen pressurizes the
delivery tanker to push the chemical from tanker to the bulk storage tank.
RAW MATERIAL STORAGE SYSTEMS SIZED TO CUSTOMER NEEDS
Stable storage and
handling of polyol, isocyanate, blowing agents and additives ultimately lead to
higher quality products. Crown Chem’s state-of-the-art equipment and technology
for intermediate and bulk storage solutions are designed to maintain raw
materials at the optimum processing condition.
