Environmental Impact Assessments


The concept of sustainable development is defined as 'development that meets the needs of the present without compromising the ability of future generations to meet their own needs.' Sustainable development has become an important strategy for economic and social development in the 21st century due to the increasingly serious problems of environmental pollution and lack of resources. Environmental impact assessment (EIA) is the term used for the assessment of the environmental consequences (positive and/or negative) of a plan, policy, program, or project prior to the decision to move forward with the proposed action. Alfa Chemistry uses various simulation methods to analyze, predict, and evaluate the possible impacts of the ecological environment, and we also propose effective strategies and measures that can prevent and reduce environmental hazards, as well as tracking and monitoring approaches.

Advantages of EIA

  • Improve the utilization rate of raw materials and energy.
  • Reduce pollution to the environment.
  • Reduce harm to the human body.

Our services

Alfa Chemistry provides environmental impact assessments for you. We introduce environmental influence factors into our advanced simulation technology to control and optimize the existing chemical process. Our environmental impact assessments services include the following:

  • Pinch point analysis

The pinch point analysis method is developed based on thermodynamics. It analyzes the distribution of energy flow along the temperature in the process system, and is able to find out the 'bottleneck' of the energy used by the system. Our groups use it to design an energy-saving strategy to eliminate the bottleneck and build a process system with minimal environmental impact.

  • Simulation method

Our scientists have created an environmental assessment using simulation approaches. Our advanced simulation software can provide a higher-level perspective and evaluate the environmental impact of dynamic systems in detail. We are able to understand how minor adjustments to the process will affect the system with the use of simulation software. In addition, our software focuses on environmental sustainability, so it is efficient when there is a need for both productivity assessment and environmental assessment. At Alfa Chemistry, we provide both static assessment and dynamic assessment to predict how the system operates and reacts after adjustments of the system.

  • Waste reduction algorithm

We integrate the waste reduction algorithm into the environmental assessment system, and our algorithm considers multiple potential environmental indicators including ozone layer depletion, human toxicity, and ecotoxicity. In addition, we also combine environmental hazard and risk assessment tools with HYSYS software for the selection of separation technology from the waste recovery process and the optimization of process operating conditions.

  • Exergy-economics method

Our teams apply the exergy-economics method used to the energy conversion system to the whole process system. Energy analysis and exergy analysis of any process system are carried out at different levels through the establishment of energy flow structure model. In addition, considering the minimum exergy loss as a constraint condition and using the network thermodynamic method, we combine exergy and the ecosystem to explore the chemical process with minimal environmental impact.

Our Advantages

  • Alfa Chemistry helps to evaluate how a chemical will respond if it enters environment and determines how chemicals can enter and harm our environment.
  • Our approach considers both economic costs and environmental impact.

Environmental impact assessments provide an effective way to optimize the chemical process. Our environmental impact assessments services remarkably reduce the cost, promote further experiments, and enhance the understanding of chemical process for customers worldwide. Our personalized and all-around services will satisfy your innovative study demands. If you are interested in our services, please don't hesitate to contact us. We are glad to cooperate with you and witness your success!
