Current Carbon Capture Technology

Current Carbon Capture Technology – Electrolyzer Coating Systems – Cheersonic

Carbon capture technology has already taken shape. For waste gas with a carbon dioxide concentration of about 10%, the cost of enriching carbon dioxide is currently about 200 yuan/ton. The current mature method is to use amine washing method. Other methods such as adsorption method, membrane separation method, cooling separation method can only be used in some special cases. For details, see my previous article.

There is currently no reliable, safe, low-cost, and large-scale utilization of the collected carbon dioxide. The existing carbon dioxide conversion technologies mainly include:

1. Use carbon dioxide as a raw material to prepare small organic molecules such as oxalic acid and isocyanic acid. The scale is small and it is difficult to make a profit;

2. The injection of carbon dioxide into the oil layer to improve the oil recovery rate of the oil field is called carbon dioxide flooding technology, which has been applied in many places at home and abroad;

3. Preparation of chemicals by hydrogenation of carbon dioxide. Note that the hydrogen here must be “green hydrogen”, which is hydrogen produced from clean energy sources. If you use hydrogen obtained from methane reforming, it will not be worth the loss (because methane reforming hydrogen produces carbon dioxide at the same time).
This technology is very dependent on the cost of “green hydrogen”. At this stage, the technology has initially been profitable. In the future, the price of “green hydrogen” will drop and the cost of carbon dioxide emissions will increase, and this technology may be applied on a large scale;

4. Electrocatalytic carbon dioxide conversion. It is still in the laboratory stage, mainly limited by electricity bills, durability of catalysts, product separation costs and the cost of catalytic stacks.

In conclusion, capturing carbon dioxide from exhaust gas is no longer a technical problem. The current pain point is how to convert and profitably capture carbon dioxide safely, on a large scale, and efficiently, that is, how to recycle carbon dioxide.

Ultrasonic coating equipment can be used in carbon capture electrolysis applications, which apply catalysts to membranes used to separate and capture CO2 before entering the atmosphere. CO2 is separated from other gases in waste gas streams produced in industrial processes, such as coal and natural gas-fired power plants or steel and cement plants; designed to reduce carbon emissions to combat global warming.

Our coating solutions are environmentally-friendly, efficient and highly reliable, and enable dramatic reductions in overspray, savings in raw material, water and energy usage and provide improved process repeatability, transfer efficiency, high uniformity and reduced emissions.
