Petrochemical Waste
Petrochemical industries, having shown significant growth over the past few decades in oil and gas-producing countries, can be considered an important source of hazardous waste due to the presence of highly toxic chemicals and heavy metals. Effluents released by petrochemical industries contain a large amount of polycyclic and aromatic hydrocarbons, phenols, metal derivatives, surface-active substances, sulfides, naphthenic acids and other chemicals. Due to the ineffectiveness of purification systems, effluents may become seriously dangerous, leading to the accumulation of toxic products in the receiving water bodies with potentially serious consequences on both aquatic and human life.
Petrochemical plants generate a variety of solid waste streams. Basically, petrochemical solid waste streams fall into two main groups:
a- Intermittently generated wastes: Intermittent wastes are generally those that result from cleaning within the process areas and off-site facilities. Spent catalysts from certain processing units and product treatment wastes, process vessel sludge, and storage tank sediments are examples of intermittent wastes.
b- Continuously generated wastes: Continuous wastes are those that require to be disposed of at less than two weeks intervals. These wastes can be further can be categorized into two groups i.e. process unit wastes and wastewater treatment wastes.
Some Petrochemical industries have managed their waste products by discharging them into the environment without previous treatment. It caused increasing pollution and had an adverse environmental impact.
Different kinds of heavy metals and hydrocarbons spread into water sources through the illegal discharge of petrochemical wastewater.
The underground water is contaminated by pouring the petrochemical waste into landfills and also, and the Open burning of this waste cause air pollution seriously.
Environment-friendly treatment of hazardous waste has the attention of the scientific community in recent years. One of the most favorable and effective disposing methods is the Pyroltech Platform process, which is an environmentally friendly and efficient way.
Petrochemical Waste items:
• Waste oil and process oil residues
• Spent catalysts
• Spent adsorbents
• Molecular sieves
• Spent resins
• Coke
• Anthracite waste
• Polymeric waste
• Contaminated clays
• Sludge
• Other waste such as contaminated packaging materials
Reusable and Recyclable Petrochemical Waste
More than 90% of generated waste in petrochemical industries convert to material or energy through recycling or the recovery process.
According to EPA and Basel Convention, all generated waste in Petrochemical Complexes is named Hazardous Waste, except for polymer waste and polymerized solvent.
Polymer waste, polymerized solvent, and sludge are Organic Waste with High Calorific Value.
Recyclable Petrochemical Wastes are as the follows:
• Spent Catalyst
• Polymer Waste
• Spent Industrial Soil
• Polymerized Solvents
• Sludge
Pyroltech’s Technology
Petrochemical wastes are an unstable composition of cyclic hydrocarbons along with heavy metals.
Pyroltech offers the New Solution for recycling, reducing, and energy recovering Petrochemical Wastes.
Pyroltech System is indispensable and logical for using different petrochemical wastes as there are in these Complexes instead of using special approved Trucks for Transportation of the hazardous wastes to approved Sites as they have permission rights from the Environment sector of government on special items!
Pyroltech’s focus is on offering the best operation scenario on the waste management system to maximize economic efficiency by recovering energy and also solve improper disposal problems and adverse environmental impacts on petrochemical industries.
