Direct carbon air capture (DAC) , called DAC for short, is one of the few technologies that can remove carbon dioxide directly from the atmosphere. DAC technology can be visualized as industrial "photosynthesis", The DAC system captures carbon dioxide on the surface of a filter coated with a special chemical, where it forms a compound. The new compound is heated to release the captured carbon dioxide and separate it from the chemical, which can then be recycled. Carbon dioxide recovery can be achieved more efficiently using DAC compared to other carbon dioxide reduction techniques such as afforestation.

Effectively reduce the tower kettle temperature and improve product quality and yield.

Evaporation Technology Introduction
Falling Film Evaporation is a process in which the liquid feed is introduced into the upper header box of the heating chamber of a falling film evaporator, and then evenly distributed to each heat transfer tube by a liquid distribution and film-forming device. Under the effects of gravity, vacuum induction, and gas flow, the liquid forms an even film that flows down from top to bottom. In the distillation unit, the vapor phase directly enters the tower for distillation, while the liquid phase is discharged from the separation chamber or circulated back into the evaporator by the pump.

Technical Principle of Evaporation Technology

Design conditions: we use the most safe and stable falling film reboiler model in present day, and the falling film introduces the multi-level distribution form including the distribution plate and the film distribution header.

Process Calculation: based on the calculation of advanced simulation software, key parameters such as gasification rate, circulation volume, flooding factor, gas-phase rate, heat exchange area, etc. are determined.

Distillation Technology Introduction
DODGEN has adopted and combined advanced distillation technology. Relying on strong technical design and the R & D team, a perfect and flexible test center and high cost-effective tower internals manufacturing base have been established to provide customers with premium quality solutions.

Packed column working principle

Gas-liquid two-phase contact through countercurrent for interphase heat and mass transfer. The volatile components in the liquid phase enter the gas phase, and the nonvolatile components in the gas phase enter the liquid phase, so almost pure volatile components can be obtained at the top of the tower and almost pure nonvolatile components can be obtained at the bottom of the tower. The feed liquid is added from the middle of the tower, and the tower section above the feed inlet further enriches the volatile components in the rising steam, which is called the distillation section; The tower section below the feed inlet extracts volatile components from the descending liquid, which is called the stripping section. After the steam from the tower top is condensed, part of the condensate returns to the distillation tower from the tower top as reflux, and the rest distillate is the tower top product.

Continuous Flow Reactor(2023年12月03日)

dgchemtech — 2023-11-23T11:50:18+0900

https://www.dgchemtech.com/products/continuous-flow-reactor/

A continuous flow reactor is a reactor in which a chemical reaction takes place in a continuous stream of fluid or gas. Unlike batch reactors, which operate on a cycle, continuous flow reactors carry out a process on a steady-state basis. These reactors are widely used in the chemical and pharmaceutical industries, where they offer a more precise control of reaction conditions and better safety by limiting the accumulation of hazardous substances. They are known for their high productivity, better selectivity, and energy efficiency.

What Are The Institutional Components Of A Continuous Flow Reactor?
A continuous flow reactor is a device in which chemical reactions are carried out continuously. During the reaction process, the reactants and solvent flow continuously and complete the chemical reaction process simultaneously. A continuous flow reactor consists of: stirring, mixing (or heating) system, temperature control system and other components.

What Are The Advantages Of Continuous Flow Reactors?
1. Improved efficiency: a continuous flow microreactor is designed to operate continuously without interruption, thereby improving the efficiency and reducing the time required to complete a reaction.

2. Consistency: because reactions occur continuously, the output from a continuous flow reactor is typically more consistent than that from a batch reactor.

3. Scalability: continuous flow reactors are easily scalable, capable of running from small to large scales, allowing for easy expansion and adapting to changing production needs.

4. Safer operation: the continuous flow reactor provides a safer operating environment as it is designed to control exothermic reactions, mitigate hazards, and reduce the risk of accidents.

5. High product quality: the continuous flow reactor minimizes impurities during production, resulting in high-quality products.

6. Cost-effectiveness: continuous flow reactors may be initially expensive to set up, but they tend to be more cost-effective than batch reactors in the long run because of their higher efficiency and throughput.
