Rigorous experimental procedures

The company has the ability to carry out distillation separation experiment, reactive distillation experiment and fixed bed reaction experiment, and has carried out more than 100 experiments successively, with rich experience and professional technical team. The laboratory R&D center strictly implements the standardized experimental operation process and quality control system, from the screening and pretreatment of experimental raw materials, to the precise

Ability of analog computing

The team has a variety of advanced chemical simulation software application capabilities, such as Aspen Plus, Pro II, HTRI, FRI, COMSOL Multiphysics, etc. These softwares cover many fields, such as chemical process simulation, heat exchanger design calculation, hydraulic calculation of internals, hydrodynamic simulation, etc. They can theoretically model the actual engineering process, compare the simulation results with the actual operation results, and accurately simulate various complex technological processes and physical and chemical phenomena in chemical production.
