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

 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

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

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 1,000 GPM @ 250 PSI.

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.”

“ 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.”
