Complex Oil Separation & Hydrocarbon Recovery
Hydrocarbon recovery has pushed a few companies to further treat the sludge with the incentive of recovering usable product. The residue created here has now higher content of large and light solid particles, organic and non-organic matter, making it less attractive for a economically viable solution.
Sludge processing and full remediation and neutralization of contaminants and residue requires many stages. Equipment in combination with additives specialize in separating each component to then process it further. Finally, the elimination of contaminants and residual hydrocarbons completes the job. Result is Waste Volume Reduction by 90 %
Our Mobile Modular Systems are designed for the complete process of any sludge or petroleum waste, separate, recover and remediate all components with the reduction of TPH, PAHs and contaminants.
These are the main stages:
1. Primary Separation - Crude Oil
Primary separation outs most emphasis on separating and recovery hydrocarbons from water and from solids. Several methods can be used to improve the separation behavior of the sludge including agitator tanks, temperature, additives, coalescers. Finally Gravity separation is recovering hydrocarbons, solids are being removed, while water is collected and sent to Secondary Separation for purification and Reuse.
a. Use of Additives to increase the efficiency and enahnce separation. This are GreenZyme, a water based detergent separator for oil-water-solids and Flocculant 6, a soilds separator that also binds to and concentrates PAHs for removal.
b. Hydrocarbon Polishing units is designed to further de-water the recovered crude product.
2. Secondary Separation - Water
Secondary separation is the process of cleaning the water to reusable conditions. Water composition contains light solids and residual hydrocarbons when entering to the secondary separator. The job of this separator focuses on removing the light solids and residual hydrocarbons. Additional filtration bring water to purified and reusable conditions. In many cases additional water entering the system in the forms of emulsions or waste water has to be discharged.
a. Affluent Filtering and Purification for Discharge
Reverse osmosis systems and other traditional but effective filtration systems can be integrated into the process.
b. Bacteria Digestion & Affluent Processing
The digesters can be made in many sizes and adapted to micro, small and modular uses. An optional advantage of our Digester Systems is that they can be adapted different locations in the process very easily. Turning the secondary separator into a bacteria digester allows for water purification using biological methods. Additionally, Residual Solids can also be processed in this unit to degrade TPH, PAHs and other contaminants. This is an internal configuration option to process for both water and solids in some of the complexes.
3. Solids Removal & Containment
At many points in the separation process solids are accumulated and removed from the system. Solids will likely have contaminants like residual TPH, PAHs, Metals, other organic and non organics. They can further be processed in a digester units for residual hydrocarbon digestion or they can be dried and contained using a de-watering unit. The only way to guarantee environmentally friendly disposal is to treat solids by biological processing.
Bacteria Digestion & Processing for Contaminated Solids
Same principle as in Bacteria Digestion in Secondary separation, with a full self-contained external digester unit for biological processing. This units are modular and mobile, they can operate with other machines and separators or as standalone operation. Configured for specific affluent volumes.
