Alabaster Corp. Specialized Industrial Cleaning Products:
Alabaster Corp. Specialized Industrial Cleaning Products CS-1 Super Concentrate: The best degassing agent. This is used effectively to cut down VOCs! It cleans and degreases well also. But the degassing and emulsification ability stands out. Very strong encapsulating, emulsifying, degreasing, and cleaning properties. However, it is biodegradable and also greatly promotes the bio remediation of waste. Forms a very tight emulsion which can last up to 20 days or more!
CS-2 Super Concentrate: The best cleaner and degreaser. It also degasses very well. But the degreasing and cleaning ability stands out. Very powerful penetrating and solvent ability. However, it is biodegradable and also greatly promotes the bio remediation of waste.
Petro Clean: Multipurpose in these applications and is very effective for degassing and degreasing. Designed to encapsulate and hold volatiles within fuel in a very tight emulsion. Used correctly it can render fuel spills Non-flammable!
Slide4:
Tank Cleaning Process Step 1 – Spraying and Degassing
Set-up and test circulation pumps
1 pump (250-450 gpm) will be required for cleaning most tank sizes
Standard 2” to 3” circulation lines should be adequate
Consult with nozzle supplier to size spray nozzle with the size of existing tank and pump
Place a basket strainer at output of pump
Dilute and mix CS-1 or CS-2 as directed in material storage tank
Pump solution into tank thru top side access port
Pressure and GPM as per nozzle specs
Airless, Sherwin Williams, Gamajet, Butterworth or Cloud nozzle (or similar) recommended
Spraying process degasses tank and cleans top and side surfaces inside tank
Solution settles on bottom of tank over the sludge layer (estimated to be 50-100 mm thick)
Amount of solution is calculated to cover sludge with 2 feet of solution
Prepares tank for Step 2 in Process Spray Nozzle Tank top Access Port Sludge layer
Slide5:
Tank Cleaning Process Step 2 – Circulation and Degreasing of Sludge
Using circulation pump, circulate CS-1 or CS-2 solution throughout tank
Pump solution out of tank thru lowest access port - a floor sump is typically used
Suction line returns to pump and solution is re-sprayed back into tank after passing through the basket strainer
Basket strainer will capture all the freed solids from the sludge layer in the tank
Monitor pressure gage. If pressure drops, empty basket strainer and resume pumping.
Circulate CS-1 or CS-2 for 24 –36 hours
Dissolves sludge into solution
Separates solids from hydrocarbons which will float on top of the solution
If product recovery is desired, this can be done by skimming product from top layer of liquid before the evacuation stage in Step 3
Although, for the tanks with minimal sludge, product recovery unlikely to be practical.
Prepares tank for Step 3 in Process Sludge layer CS-2 circulation Pump Basket Strainer
Slide6:
Tank Cleaning Process Step 3 – Solution Evacuation and Liquefied Sludge Removal
After 24-36 hours, solids in sludge will have been liquefied and pumped from tank
Hydrocarbons will be separated from solids in sludge and emulsified into CS-1 or CS-2 solution
Solids will have been recovered from basket strainer and will be ready for removal from site
Reconfigure pump to evacuate wastewater from tank
Pump wastewater from tank
Oily wastewater can be pumped to API pit
Alternately, this wastewater can easily be bioremediated using microbial additives, if desired
In cases where product recovery is desired, the wastewater can be left to stratify and product can be skimmed from the surface Pump CS-2/liquified sludge solution Recovered

Slide7:
Tank Cleaning Process Step 4 – Second Cleaning (if necessary)
Repeat steps 1 and 2 with second batch of CS-2 solution
Inner tank surfaces should be very clean
Remaining CS-2 solution should be fairly clean
Remove spray nozzle from tank
Pump CS-2 out into storage tank for re-use as first wash on next tank
If second cleaning is not needed, spray water through nozzle for 3-4 hours
Remove nozzle
Pump out tank, send wastewater to API pit
If maintenance requirements dictate, an air mover (such as a COPUS blower) can be introduced into the
tank to dry tank and promote air circulation Pump Residual contaminants and CS-2 solution OR rinse water Recovered
