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 !

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

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

DYNMCDERMOTT PETROLEUM THE TEXCHEM SYSTEM DYNMCDERMOTT PETROLEUM “… 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

THE TEXCHEM SYSTEM DIAMOND SHAMROCK “ 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.” Charles Patry Vice President, Supply Ultramar Diamond Shamrock
