How Much Does an Oil Sludge Thermal Desorption Unit Cost? A Look at CAPEX

By Cathy Wang • February 25, 2026
For companies in the petrochemical, drilling, or refining sectors, oil sludge is one of the most challenging by-products to manage. Classified as hazardous waste in most jurisdictions, it poses significant environmental risks if not treated properly. Fortunately, pyrolysis technology—specifically thermal desorption— offers a highly effective solution to separate hydrocarbons from solid waste, recovering valuable oil while rendering the solids inert. However, for engineering managers and investors, the first question is rarely about the chemistry; it is about the cost. What is the capital expenditure (CAPEX) required to bring an oil sludge thermal desorption project online? The answer varies dramatically based on scale, technology, and automation levels. Generally, the investment can range from a few hundred thousand RMB for a small pilot unit to upwards of 5 million to 30 million RMB (approx. $700,000 to $4.1 million USD) for a large-scale, continuous industrial plant. Understanding the Price Tiers To help you budget effectively, it is useful to break down the market into three distinct categories of thermal desorption units (TDUs). 1. Small Pilot & Lab-Scale Units (CAPEX: Tens of thousands RMB) These are the entry-level systems, typically used for research, feasibility studies, or treating very small, batch-specific quantities of waste. Typical Cost: ~¥200,000 – ¥800,000 RMB. Capacity: Usually 1 ton to 5 tons per day. Configuration: Simple batch reactors with manual feeding and discharge. They prove that the process works for your specific sludge but are rarely economical for large-scale remediation. Best For: Universities, research labs, or companies testing the viability of thermal treatment before scaling up. 2. Mid-Scale Modular Units (CAPEX: ¥2 Million – ¥10 Million RMB) This is the sweet spot for many contractors and industrial sites that need to process waste on-site without massive civil works. Typical Cost: ~¥2,000,000 – ¥10,000,000 RMB. Capacity: 10 tons to 30 tons per day. Configuration: Often semi-continuous or fully automatic batch systems. These units feature improved safety mechanisms, basic emission controls, and better oil recovery rates. Best For: Small refineries, oil field service companies, or environmental remediation firms handling localized contamination. 3. Large-Scale Industrial Continuous Systems (CAPEX: ¥15 Million – ¥30 Million+ RMB) For large refineries or centralized hazardous waste treatment centers, scale is everything. A continuous thermal desorption unit is the pinnacle of the technology, designed to run 24/7. Typical Cost: ~¥15,000,000 – ¥30,000,000 RMB (or more depending on auxiliaries). Capacity: 50 tons to 100+ tons per day. Configuration: Fully continuous rotary kilns or screw reactors. These systems are highly automated, featuring PLC controls, sophisticated cooling towers, non-condensable gas recirculation for fuel savings, and multi-stage pollution control to meet stringent emission standards. Best For: Major petrochemical complexes, large-scale refineries, and government-approved industrial waste hubs. What is Included in the CAPEX? When budgeting for a thermal desorption unit , the reactor itself is only half the story. A complete CAPEX estimate for a project usually includes: The Main Reactor: The heart of the system, usually a rotary kiln or heated screw conveyor where desorption occurs. Feeding & Discharge Systems: To handle the sticky, messy nature of oil sludge, you need robust screw conveyors or piston feeders. Condensation System: A series of heat exchangers and coolers designed to condense the vaporized hydrocarbons into liquid oil. Pollution Control: A crucial element. This includes ceramic packing towers, desulfurization units, and dust removal systems to ensure off-gas is clean. Safety & Instrumentation: PLC control rooms, pressure/temperature sensors, and flare stacks for handling excess syngas. The ROI Perspective While a 30 million RMB price tag might seem steep, it is essential to view this through the lens of Return on Investment (ROI). A TDU converts a liability (sludge) into assets: Recovered Oil: Sold as industrial fuel or reprocessed. Recovered Solids: Non-hazardous soil or sand that can be used for construction or landfill cover, saving on disposal fees. Avoided Fines: Compliance with environmental regulations prevents substantial penalties. Depending on local gate fees for hazardous waste disposal (which can be extremely high) and the price of crude oil, many investors find that large-scale units pay for themselves within 2 to 4 years. Conclusion Investing in an oil sludge thermal desorption project is a significant financial decision. While small pilot units offer a low-cost entry point for testing, industrial-scale remediation requires a CAPEX typically in the range of 5 million to 30 million RMB. Understanding your throu ghput requirements and the purity of the end products you need will help you navigate this wide range and select the technology that fits your long-term strategic goals.

Influence of Plastic Purity on Pyrolysis Efficiency

By Cathy Wang • February 11, 2026
Plastic waste has emerged as a significant environmental challenge due to its persistent nature and widespread use. Pyrolysis, a thermochemical process, offers a promising route for converting plastic waste into valuable products such as fuel oil, gas, and solid char. However, the efficiency of the pyrolysis process is heavily influenced by the purity of the plastic feedstock. The presence of impurities, such as other polymers, metals, and additives, can substantially affect the yield, quality, and energy consumption of the pyrolysis process. The Role of Plastic Purity in Pyrolysis Composition and Reaction Pathways The purity of plastic directly determines the composition of the feedstock entering a pyrolysis plant . Plastics are made up of a range of polymer types, such as polyethylene (PE), polypropylene (PP), polystyrene (PS), each with different molecular structures and thermal decomposition behaviors. Pure plastic feedstock, often consisting of a single polymer, undergoes a more uniform and predictable pyrolysis process. Impurities, such as metals, glass, or mixed polymers, introduce additional complexity to the thermal degradation process. These contaminants can either promote undesirable side reactions or hinder the efficient degradation of plastic polymers. For example, the presence of metals can catalyze the formation of unwanted byproducts like tar and carbon black, leading to lower-quality outputs. Mixed polymers, on the other hand, may decompose at different temperatures, complicating heat transfer and slowing down the reaction rate.

The Impact of Biomass Pretreatment Methods on Pyrolysis Process: Drying, Grinding, and More

By Cathy Wang • February 6, 2026
Biomass pyrolysis is a promising method for converting organic materials into valuable products such as biochar, bio-oil, and syngas. However, the efficiency and quality of these products depend not only on the pyrolysis process itself but also on the pretreatment of the biomass feedstock. Pretreatment steps like drying, grinding, and other methods can significantly influence the pyrolysis process, especially when scaled up in a biomass pyrolysis plant. In this article, we'll explore how these pretreatment methods impact the pyrolysis process and the final products. Biomass Pretreatment: Why Does It Matter? Biomass feedstocks come in a wide variety of forms, including wood chips, agricultural residues, and food waste. Each type of biomass has different physical and chemical properties that affect its performance during pyrolysis. Pretreatment is crucial because it can enhance the efficiency of the pyrolysis process, optimize the yield of valuable products, and improve the economic feasibility of the operation. A biomass pyrolysis plant typically handles feedstocks that may need different levels of preprocessing to achieve the best results. Let's take a look at the most common pretreatment methods used in biomass pyrolysis. 1. Drying: A Crucial Step for Pyrolysis Efficiency One of the first steps in biomass pretreatment is drying. Biomass materials typically contain a significant amount of moisture, which can vary greatly depending on the type of feedstock and its source. Moisture content and its impact: High moisture content in biomass can significantly affect the efficiency of the pyrolysis process. During pyrolysis, moisture evaporates and absorbs heat, which can reduce the temperature inside the reactor, slowing down the reaction and lowering the yield of valuable products like bio-oil and syngas. Furthermore, high moisture can also lead to more tar formation, which can complicate the operation of the biomass pyrolysis plant . Optimal moisture levels: Studies suggest that biomass with moisture content below 10% is ideal for efficient pyrolysis. Therefore, drying biomass before introducing it into biochar reactor can enhance the overall process, improve heat transfer, and increase the yield of biochar and bio-oil. Drying methods include air drying, oven drying, and rotary dryers, with rotary dryers being commonly used in biomass pyrolysis plants due to their high capacity and efficiency. 2. Grinding: Improving Feedstock Uniformity Once the biomass is dried, the next critical step is grinding or milling the material to a suitable particle size. Biomass that is too large or too irregularly shaped can hinder the pyrolysis process, leading to uneven heating and inconsistent product formation. Particle size and its impact on pyrolysis: Smaller particle sizes increase the surface area of the biomass, allowing for more efficient heat transfer during pyrolysis. This leads to faster pyrolysis reactions and improved yields. For example, wood chips or agricultural residues are typically ground to a size below 20 millimeters to maximize efficiency. Grinding methods: There are several ways to grind biomass, including hammer mills, ball mills, and disk mills. Each method has its advantages depending on the material being processed. Biomass pyrolysis plants often integrate grinding systems to ensure that the feedstock is consistently prepared for the pyrolysis reactor. Uniformity and consistency: Grinding also helps in achieving uniformity in the feedstock. Biomass with a consistent size can ensure more uniform heating, reducing the chances of incomplete or inefficient pyrolysis. Conclusion Incorporating effective pretreatment methods such as drying, grinding, torrefaction, and pelletizing plays a crucial role in optimizing the performance of biomass pyrolysis plants. These steps improve feedstock quality, enhance pyrolysis efficiency, and maximize the yield of valuable products. As the biomass pyrolysis industry continues to grow, innovation in feedstock pretreatment technologies will be key to improving the sustainability and profitability of bioenergy production. If you're considering setting up or improving a biomass pyrolysis plant, investing in the right pretreatment techniques could make all the difference. Whether you're working with wood chips, agricultural waste, or other biomass materials, the proper preparation can ensure that your pyrolysis process operates at peak efficiency, providing a more sustainable and profitable energy solution.
