What is waste? Bottom tank sludge can be considered waste or product, depending on the capabilities and desires to process it. "Waste is in the eye of the beholder". The European Waste Framework Directive established the guileless for what is considered waste vs secondary raw material or by products, while also regulating the transports of such to prevent endangering human health and harming the environment.
Many facilities are not prepared nor desire to process the bottom tank sludge so they declare it as waste and remove it from the facility for an outsourced entity to see best way to deal with it. It is important to understand if the lack of desire for processing is the lack of belief on a real and viable solution for this waste sludge to be processed, its volume reduced and the hydrocarbons recovered. In the past, such enterprise required a complex, complicated and costly processing.
Waste Processing Costs
Local governments have resorted to offering subsidies for each ton processed of accumulated waste, while NOCs and Tank Terminals resort to 3rd parties to handle their waste operations. The petroleum waste processing market ranges from (USD) 80$/ton for separation facilities in Santa Cruz, $130 for processing drilling site waste in low policing territories like Neuquen or $140/ton and for Production waste pit clean-up in Daqing. In European Markets processing the waste generated by facilities in Rotterdam can cost up to $400/ton for removal from the facilities grounds, transport permits, carbon certificates and finally detached ultimate waste reduction most likely with the production of Greenhouse gases (hence the carbon certificates).
3 Key Benefits and Motivators of Bottom Tank Sludge Processing & Waste Volume Reduction
Presenting a guaranteed solution for the processing of sludge, can turn waste into product in many facilities. The recovery of hydrocarbons can be the right motivator for performing waste reduction practices and increase Performance Evaluation of many facilities by keeping tanks online more time.
An additional benefit will be for the use of on-site waste reduction solutions, which will allow for facilities to have less to dispose of when removing waste from their facilities, which eventually reduces the cost of the operation and movement of the hazardous waste.
Finally, when all waste can be processed, separated while having the final residues neutralized from contaminants on-site, the facility can discharge the remaining decontaminated non-hazardous affluent safely in the environment minimizing waste removal cost and improving environmental scores.
Bottom Tank Sludge Solution
Tank Terminal Master Complex 6000 is the specialized solution for Terminal and Storage Tank clean-up and servicing. Operationally, the complex has a starting processing cost of $50/m3. It uses Steam Jets fluidize sludge in the tank and remove it for automatic external processing. The external unit can simultaneously perform separation and recovery of hydrocarbons, filter and purify water for reuse into the Jets or discharge, finally contain solids to comply with waste volume reduction practices.
This system can also be outfitted with a digester to fully guaranteed neutralization of residues and solids from hydrocarbons and other contaminants and metals in an environmentally friendly way.
