Analysis of Application Cases of VOC Recovery Machines
Case One: Pharmaceutical Industry - From "High-Value Solvent Waste Liquid" to "Raw Material Grade Recovery"
The pharmaceutical production process uses a large amount of high-value organic solvents (such as dichloromethane, toluene, ethanol, etc.). Recovering them from waste gas and redistilling for reuse can create significant cost reduction and efficiency improvement value.
Case 1: "Resin Adsorption Upgrade" of Shandong Chuancheng Pharmaceutical
Technical solution: Upgrade the original activated carbon adsorption to resin adsorption to effectively treat the workshop exhaust gas.
Economic benefits: It is estimated that the annual recovered solvent volume will reach 273.6 tons, with the recovery rate increasing from 0 to 20%, and the annual operating cost will be reduced by 1.3 million yuan.
Case 2: "Solvent Distillation Recovery" of Dijia Pharmaceutical
Technical solution: An investment of 11.6883 million yuan was made to build three sets of solvent distillation and recovery devices to distill and recover solvents such as toluene, ethanol, and ethyl acetate generated during the production process.
Economic benefits: The project scale reaches an annual solvent recovery of 3,300 tons. The recovered solvents are directly reused in the production of active pharmaceutical ingredients, generating significant economic value.
Case 3: Clean Production of Pharmatech
Technical solution: By means of continuous ozonation reaction and other technologies, the use of solvents and the generation of pollutants are reduced from the source.
Economic benefits: It is estimated that the cost savings will be 3 to 3.5 million yuan per year, achieving a significant effect of pollution reduction at the source.
Case Two: "Green Island" Model - A New Path for Shared Pollution Control among Small and Medium-sized Enterprises
In response to the pain points of small and medium-sized enterprises such as high pollution control costs, difficult technology application, and challenging supervision, the "Green Island" model has emerged. By building shared environmental public infrastructure, it centralizes the treatment and recovery of dispersed VOCs emissions, achieving large-scale and intensive pollution control.
Benchmark Case: "Lebang Environmental Protection Green Island" in Xintai, Shandong Province
Technical solution: A complete industrial chain has been established, covering the entire process from paint research and development, spraying processing to paint residue recycling, achieving full utilization.
Environmental benefits: The VOCs treatment efficiency in the park is as high as 99.7%, and the paint residue is transformed into high-molecular solid powder, which is applied to 16 types of products.
Economic benefits:
Shared benefits: The average operating costs of contracted customers have been reduced by approximately 15%, and the product qualification rate has been increased to over 95%.
Cyclical benefits: The annual output value of paint residue recycling reaches 20 million yuan.
Transformation significance: It has transformed "chemical engineering" into "new materials", and turned the transformation of a single enterprise into an upgrade of the regional industrial chain. This model has been promoted in many places across the country. For instance, the centralized paint and repair center for auto 4S stores in Chenzhou, Hunan Province, has adopted a similar model.
