Carbon dioxide drying device: efficient process flow, easy to control productivity

In response to the national call for "peak carbon emissions and carbon neutrality", this project plans to construct a carbon capture project with an annual output of 200000 tons. The project is located in Xinjiang and relies on supercritical indirect air-cooled combustion power generation units. The carbon dioxide recovery unit processes 125000Nm ³/h of flue gas and recovers approximately 25T/h of carbon dioxide. The captured portion is purified to obtain carbon dioxide with a purity greater than 99%, which is then compressed and liquefied in a system to produce industrial grade liquid carbon dioxide products that meet national standards. These products are widely used in fields such as oilfield fracturing, oil recovery, and enhanced oil recovery.

Dehydration purification is an important part of CCUS, and our company is responsible for the dehydration pry unit in carbon dioxide purification in this project. We fully utilize our professional advantages in the dehydration field and tailor solutions to meet the on-site needs of our customers. This dehydration device adopts our company's independently innovated and developed three tower adsorption advanced process, which has zero gas consumption and zero emissions throughout the process, and has the comprehensive advantages of small regeneration gas volume, short time, thorough regeneration, low dew point, and low noise. It can fully meet the pressure dew point requirements as low as -70 ℃.

On the premise of ensuring product performance and safety, this process switches and stores heat between the three towers, effectively utilizing the waste heat of the tower and pipeline, and significantly reducing the average energy consumption. It is the product with the lowest energy consumption among all similar products. In addition, the device adopts fully intelligent control and has a highly convenient remote monitoring system, which enables our company to real-time understand the on-site operation of the equipment and provide reliable technical services to users in a timely manner. It truly realizes the three in one concept of "intelligence, energy saving, and efficiency" and insists on providing the most solid and powerful guarantee for product quality.
Our progress is only aimed at providing users with true convenience and peace of mind
