TWENTY-FIRST CENTURY TANK CLEANING

TWENTY-FIRST CENTURY TANK CLEANING

WHY USETHE TEXCHEM SYSTEM? WHAT IS THE TEXCHEM TANK CLEANING SYSTEM? WHAT ARE THE SYSTEM CAPABILITIES? HOW DOES THE SYSTEM WORK? WHAT ISTHE PROJECT HISTORY OF THE SYSTEM? THE TEXCHEM SYSTEM

FASTER SAFER MORE ECONOMICALLY MORE EFFICIENTLY THE TEXCHEM SYSTEM THE TEXCHEM SYSTEM WILL REMOVE YOUR TANK SLUDGE AND RETURN YOUR TANK TO SERVICE 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 • 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 • TREATING TANK BOTTOMS WITH CUTTER STOCK • 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

THETEXCHEMTANKCLEANINGSYSTEM 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. THE TEXCHEM SYSTEM PROCESS COMPONENTS : • C-105 SLUDGE TREATMENT CHEMICAL PROGRAMS • ENGINEERED TREATMENT CHEMICAL DELIVERY SYSTEM • EFFICIENT SOLIDS REMOVAL, FLUID RECIRCULATIONAND CRUDE OIL RECOVERY SYSTEM

40-60% REDUCTION IN TANK CLEANING AND OUT-OF- SERVICE TIME ELIMINATION OF CUTTER STOCK AND/OR EXTERNAL HEAT REDUCTION OF AIR EMISSIONS FROM CLEANING OPERATION EFFICIENT & SAFE REMOVAL OF ALL TANK SOLIDS 99% RECOVERY OF CRUDE OIL FROM TANK SLUDGE NO UPSTREAM REFINING IMPACT FROM RECOVERED CRUDE EFFICIENT SOLID AND LIQUID SEPARATION SYSTEMS TO MEET DISPOSAL OR RECYCLING REQUIREMENTS 20-40% REDUCTION IN VOLUME OF WASTE FOR DISPOSAL THE TEXCHEM SYSTEM TEXCHEMTANKCLEANINGSYSTEM CAPABILITIES :

C-105 CHEMICAL PROGRAMS (U.S. PATENT # 5,858,247) : THE TEXCHEM SYSTEM • 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

CHEMICAL DELIVERY SYSTEM - OPERATING CRITERIA : THE TEXCHEM SYSTEM • 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 1,000 GPM @ 250 PSI.

CRUDE OIL TANK - ARDMORE, OK (150’ diameter, external floating roof) CONTENTS : 2,000 Barrels (458 Tons) of Crude bottoms ( paraffins, resins & asphaltenes) CUSTOMER SPECIFICATION : Recovered Crude less than 0.5% BS&W; Removed solids to Customer Centrifuge plant. TEXCHEM PERFORMANCE : Cleaned in 9 days; Complete solids removal; Recovered Oil < 0.5% BS&W; No measurable organic vapors from operation THE TEXCHEM SYSTEM • SLURRY OIL TANK - PORT ARTHUR, TX (120’ diameter, fixed roof) CONTENTS : 38,000 Barrels (7,580 Tons) of sludge - (catalyst fines, paraffins asphaltenes & other sediment) CUSTOMER SPECIFICATION : Removed solids @ 30% dry weight (moisture balance); Recovered oil less than 5.0% BS&W. TEXCHEM PERFORMANCE : Cleaned in 150 days; Complete solids removal; Removed solids @ 95% dry weight (moisture balance); Customer saved $3.5 million on disposal; Recovered Oil < 1.0% BS&W; Customer reused C-105 treated oil to recover oil from adjacent tank; No measurable organic vapors from operation.

THE TEXCHEM SYSTEM DYNMCDERMOTT PETROLEUM “…revolutionary fluidization process using the C-105chemical 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
