Waste Organic Solvent-to-Energy and Reuse

General Descriptions

Waste organic solvents are prevalent in industries such as chemical engineering, optoelectronics, and semiconductors. Currently, the more mature treatment methods include separation and recovery for reuse or destructive incineration. However, existing technologies face challenges when dealing with diverse organic solvent compositions or wastewater containing ammonia; the procedures are often complex, the efficiency of recovered waste heat is low, and there are potential pollution risks such as incomplete combustion. To address these issues, our company has introduced the concept of "Cracking and Reuse." By decomposing complex organic components or ammonia into gaseous combustible components—such as methane, short-chain carbon compounds, carbon monoxide, and hydrogen—they can be used as process substitutes or fuel for power generation. This approach reduces pollution generated during the treatment process in a cleaner manner and achieves circular reuse from an energy perspective, fully realizing the concept of a Circular Economy.

Two Core Units

Our organic waste solvent treatment technology primarily utilizes high temperatures within a unique reaction mechanism to crack organic components. Depending on client requirements, various catalysts can be introduced to adjust the composition of the end products.

The system consists of two primary core units:

1. Thermal Cracking Unit

(1.1) Purpose : To break down long-chain organic components in the feedstock into smaller molecules under high temperatures.
(1.2) Effect : Produces combustible components such as methane, short-chain carbon compounds, carbon monoxide, and hydrogen. The COD (Chemical                             Oxygen Demand) of the resulting condensate meets discharge standards.
(1.3) Key Technical Feature : Heating is provided via Natural Gas (NG) or Liquefied Petroleum Gas (LPG) burners.
(1.4) Precautions : If the waste solvent contains sulfides, halogens, or metal ions, a pretreatment process must be evaluated to minimize the impact on the 
                              system's hardware lifespan.   

2. Heat Recovery Unit

(2.1) Thermal Cracking : After the equipment reaches the preset temperature, feedstock is introduced at the designed flow rate.
                                        Once the system reaches equilibrium, combustible gas is collected at the outlet, and low-COD condensate is discharged.
(2.2) Downstream Applications: Application equipment can be installed based on specific needs:
(2.3) Steam Generation : Boilers.
(2.4) Power Generation : Gas engine generators or fuel cells (purification is required depending on the type of fuel cell).
(2.5) High-Purity Gas Production : Gas purification equipment can be integrated to obtain specific high-purity gases.

Operational Workflow

(1) Thermal Cracking : After the equipment reaches the preset temperature, feedstock is introduced at the designed flow rate. Once the system reaches
                                        equilibrium, combustible gas is collected at the outlet, and low-COD condensate is discharged.
(2) Downstream Applications : Application equipment can be installed based on specific needs:
(3) Steam Generation : Boilers.
(4) Power Generation : Gas engine generators or fuel cells (purification is required depending on the type of fuel cell).
(5) High-Purity Gas Production : Gas purification equipment can be integrated to obtain specific high-purity gases.

Key Specifications

(1) Processing Capacity per Module (Tons/Month): 10 ~ 350
     (Note: Based on a COD baseline of 400,000 mg/L).
(2) Heating Method: Standard heating via NG/LPG; electric heating is available as an option upon request.
(3) Customization: Detailed design is tailored to actual client site conditions and feedstock composition.
