New chemical separation technology:
- multi-effect distillation
Multi-effect distillation is a heat integrated distillation system that uses the latent heat of the high-pressure tower overhead steam to provide heat to the reboiler of the low-pressure tower, and the high-pressure tower overhead steam is condensed at the same time. At present, our company has multiple sets of mature devices of this separation technology in the fields of methylal, methanol separation, solvent recovery, fusel oil recovery and other fields.
- heat pump distillation
A system that transfers heat from a low level to a high level through external work is called a heat pump system. A heat pump raises the temperature of low-temperature heat energy to a level where it can be utilized at the expense of consuming a certain amount of mechanical work. Since the available heat obtained far exceeds the energy input into the system, energy can be saved. The starting point of heat pump distillation is to increase the level of part of the energy in the distillation process for its own reboiler heating needs. At present, our company has reached a friendly cooperation agreement with Shaangu to jointly develop and expand the heat pump distillation technology business.
- Thermal coupled distillation
Thermal coupling is a process structure that directly carries out material transportation and energy transfer through the reciprocal flow contact of gas and liquid phases. That is, a liquid phase stream is led from a certain tower to directly serve as the top reflux of another tower, or the gas phase is led out. The stream is directly refluxed as the gas phase at the bottom of another tower, thereby achieving direct thermal coupling. The most representative one is Petlyuk thermocouple distillation. This structure saves a condenser and a reboiler on the equipment, and due to the tower The degree of internal backmixing is reduced, and the thermodynamic efficiency of the separation process is improved to achieve energy saving effects. At present, our company has multiple sets of mature devices of this separation technology in the fields of industrial naphthalene separation, gasified phenol separation, cresol separation, fusel oil separation, C9C10 separation and other fields.
- Other distillation technologies
Our company continues to innovate in the field of chemical separation, and has established industry-university-research cooperation with universities and enterprises to conduct in-depth research and development of new distillation technologies such as molecular distillation, supergravity distillation, and capillary distillation.
