4. THAN ANY OTHER TANK CLEANING METHOD
THE TEXCHEM SYSTEM
THE TEXCHEM SYSTEM WILL REMOVE YOUR TANK SLUDGE AND RETURN YOUR TANK TO SERVICE
FASTER
SAFER
MORE ECONOMICALLY
MORE EFFICIENTLY
THAN ANY OTHER TANK CLEANING METHOD
WE BRING THE ART OF TANK CLEANING
INTO THE SCIENCE OF THE TWENTY-FIRST CENTURY !

5. CONVENTIONAL TANK CLEANING METHODS
TREATING TANK BOTTOMS WITH CUTTER STOCK
Adds Cost and Logistical Transfer Problems
Increases Air Emissions from Cleaning Operation
Impacts Physical and Chemical Characteristics of Recovered Crude Oil
Increases Process Safety Concerns due to Flammability and Organic Emissions
APPLICATION OF HEAT
Adds Cost and Time for Heat Transfer - Energy Inefficient
Heat Loss Results in Re-Solidification of Sludge
Heat Loss Creates Pumping, Circulation and Solids Separation Difficulties
Dramatically Increases Air Emissions from Cleaning Operation
Impacts Physical and Chemical Characteristics of Recovered Crude Oil
MANUAL REMOVAL (MINING)
Time Consuming (up to 6 Months For 110 Meter Tank)
Increases Process Safety Concerns due to Worker Exposure & Confined Space
Results in High Volume of Waste Requiring Disposal

7. THE TEXCHEM SYSTEM THE TEXCHEM TANK CLEANING SYSTEM IS :
TURN-KEY TANK CLEANING PROCESS TO CHEMICALLY STRIP ORGANICS FROM TANK BOTTOMS, FLUIDIZE HEAVY-END ORGANICS, AND CREATE A STABLE SLURRY, WITHOUT THE USE OF HEAT OR CUTTER STOCK, FOR THE EFFICENT REMOVAL OF TANK BOTTOMS, RECOVERY OF CRUDE OIL AND SEPARATION AND DISPOSAL OF SOLIDS.
PROCESS COMPONENTS :
C-105 SLUDGE TREATMENT CHEMICAL PROGRAMS
ENGINEERED TREATMENT CHEMICAL DELIVERY SYSTEM
EFFICIENT SOLIDS REMOVAL, FLUID RECIRCULATION AND CRUDE OIL RECOVERY SYSTEM

16. THE TEXCHEM SYSTEM C-105 CHEMICAL PROGRAMS (U.S. PATENT # 5,858,247) :
CONSIST OF A SERIES OF PATENTED, HYDROCARBON LIQUEFACTION AND DEMULSIFICATION CHEMICAL FORMULATIONS (NON-TOXIC & ENVIRONMENTALLY SAFE)
LIQUEFACTION AGENTS ARE USED TO STRIP AND LIQUIFY THE HYDROCARBON SLUDGE FROM THE INORGANIC SOLIDS TO ESTABLISH A HYDROCARBON SLURRY FOR TANK CIRCULATION
DEMULSIFER AGENTS ARE USED TO ENHANCE SLURRY FLUIDIZATION, BREAK PHYSICAL EMULSIONS, SUSPEND OR DROP OUT INORGANIC SOLIDS, AND CONDITION THE SLURRY FOR PHASE SEPARATION OF SOLIDS, HYDROCARBONS AND WATER

18. THE TEXCHEM SYSTEM CHEMICAL DELIVERY SYSTEM - OPERATING CRITERIA :
TANK ROOF ACCESS NOZZLE SYSTEM WITH AUTOMATIC AND MANUAL, VERTICAL AND HORIZONTAL ARTICULATION;
ASSURE DELIVERY OF TREATMENT CHEMICAL TO ALL AREAS OF THE TANK BOTTOM AT PRESSURES SUFFICENT TO INSURE SUSTAINED CONTACT WITH SLUDGE AND CIRCULATION OF LIQUIFIED SLUDGE;
NON-DESTRUCTIVE AND COMPATABLE WITH MOST FLOATING AND FIXED ROOF TANK SYSTEMS;
FLEXIBILITY OF BEING A PERMANENT OR TEMPORARY TANK INSTALLATION;
TYPICAL OPERATING RANGE OF 1, PSI.

“… revolutionary fluidization process using the C-105 chemical allowed us to clean tanks 1 & 2 within thirteen (13) days.” (220,000 BBL tanks)
“… your process resulted in the recovery of 50,000 barrels of crude inventory, which under conventional tank cleaning processes would have been lost with attendant disposal costs.”
“… and saved approximately $800,000 over typical mechanical cleaning processes.”
Robert McGough
Director of Operations and Maintenance

“ We have used your tank cleaning chemical C-105 in our #82 heavy oil tank at the UDS Ardmore refinery and conclude that this is a great product to reduce the level of tank bottom sludge…”
“… this is a breakthrough product that enables us to reduce substantially tank turnaround time and to recuperate in a liquid form a major portion of the tank bottom sludge that would be otherwise treated for disposal.”
