Ether Sulfates, Emulsifiers, Emulsifier Blends, Calcium & Amine Sulfonates, Antifoams, and Custom Products

• Brand names are T-Mulz, T-Det, T-Surf, T-Tergamide, Foamer and Emulzymer

• 2 alkoxylation reactors - 8,500 and 4,000 gal.– Nameplate capacity is 65 MM pounds/year

Harcros Organics – Facts and Figures

• Located in Kansas City, Kansas

– On the same site as Headquarters

• Contribute approximately 10-12% of total corporate revenues

• Produce 40 MM lbs of product annually

• 24 hour operation (5+ basis)

• 53 employees

• Access to a diverse sales force.– 100+ members – a key advantage

Kansas City – Facts and Figures

• Located in the Midwest.• 2 MM people in the greater metropolitan area.• Missouri and Kaw rivers flow through the city. • renowned for beef and barbeque style• Agriculture is a significant industry.

– State crop is wheat.• Climate:

– Annual rain total – 40 in,– Annual snow total – 20 in.– At the top of “tornado alley”

Core competencies include:

• Ethoxylation

• Propoxylation

• Phosphorylation

• Sulfation (with sulfamic acid)

• Antifoam Formulation

• Custom Blending – Agricultural, T-Mulz blends

Industries That We Service

• Agricultural Adjuvants and Inerts

• Latex emulsion Polymerization

• Industrial and Institutional

• “Oil Patch” (oil and gas recovery)

• Building Materials

• Radiation Curable Films

• Water Treatment

• Epoxies

• Paint and Coatings

• De-inking (paper recycling)

Facilities:

• Ethylene oxide plant (EO)• Liquid Blending Unit (LBU) • Formulation Plant• Pilot Plant• Acid Plant – Strictly packaging

Ethylene Oxide Plant

• Conduct both ethoxylation and propoxylation• Emerson Delta V control system.• Also prepare calcium and amine sulfonates, ether sulfates and phosphate

esters.

Liquid Blending Unit

• Produce custom and T-Mulz blends• Package containers and tank trucks.• Manufacture ether sulfates and phosphate esters

Formulation Plant

• Produce silicone and non-silicone antifoams• Also produce, small quantity, value added

products.• White room packaging

Technical Resources

• Research and Development:– Two Ph.D. Chemists (surfactant focused).

– Three B.S. chemists.

– One process engineer.

– Over one hundred combined years of surfactant experience.

• QA Lab Staffing:– Five full time, trained analysts.

– Three shifts operating.

• Equipment Availability:– FTIR, UV/VIS, AA, headspace GC, HPLC, Auto-tensiometer, Coulter -

counter, viscometers (macro and micro), autotitrators, moisture balances.

Materials that we Ethoxylate or Propoxylate:

• Alkyphenols:

– Nonylphenol

– Octylphenol (PTOP)

– Dodecylphenol

• Iso-alcohols

– Isodecyl alcohol

– Isotridecyl alcohol

• Short chain linear alcohols

• Fatty Alcohols

– C12-16 (coconut)

– C16-C18

• Polyamines

– DETA/TETA

– aminoethylethanolamine

• Castor Oil

Antifoams:

• We produce silicone and non-silicone antifoams in separate areas of the formulation plant.

• All silicone emulsion antifoams, with the exception of one, can be made as food grade products. – Activities varies from 5-30%

• We sell many block polymers (Ethylene Oxide plant) as antifoams or defoamers.

• Out total antifoam production volume is 8 MM pounds.

Custom Blending

• Most of the custom blends that we produce are directed toward the Agricultural market. – These are referred to as EC’s, or “Emulsifiable Concentrates”.

– Most are “T-Mulz” products

• There are two kettles in our Liquid Blending Unit (LBU) that are routinely used for making phosphate esters and ether sulfates.

• Energetic agitation

• Excellent heat exchange properties

Phosphate Ester Products:

• The strength of this product group is their alkali/electrolyte tolerance.

• Our phosphate esters are based mostly on our own ethoxylates (both alkylphenol and alcohol).

• Use both polyphosphoric acid (115%) and phosphorus pentoxide.

• One of our products is a phosphated acrylic monomer.– T-Mulz 1228

Ether Sulfates

• We use sulfamic acid to prepare our ether sulfates. This sulfation method is mild, and yields products with low contaminant levels.– Current volume is 3 MM pounds/year.

– Most of the volume is directed toward oil/gas recovery

• We can only produce ammonium salts directly. However, with post-processing, we can produce sodium salts.– We produce one such speacialty product, Emulzymer N4SES-AQ

• Typical batch sizes vary from 4,000 – 90,000 lbs,

Technology Platforms

• Narrow Range Ethoxylates (NRE’s).

• Functional Monomers

• Agricultural products

• NRE ether sulfates

• Fermentation Defoamers
