Product & service detail

CARBON DIOXIDE (CO2)

1. Overview

Carbon dioxide (CO2) is a colorless, odorless gas composed of one carbon atom bonded to two oxygen atoms. It is a naturally occurring chemical compound that plays a crucial role in Earths carbon cycle and atmosphere. CO2 is emitted through natural processes like volcanic eruptions and respiration, and is also a byproduct of human activities such as burning fossil fuels and deforestation. In recent years, CO2 levels in the atmosphere have been a significant focus due to their impact on global climate change.

2. Our Products

At Khoa Dung, we provide compressed carbon dioxide and liquid carbon dioxide (CO2) in various purities and concentrations, including beverage grade, food grade, and USP standards. For specialized applications, we offer CO2 in high-pressure gas cylinders and liquid CO2 mists of different sizes.

3. Applications

☑ Food & Beverage:
Carbon dioxide serves as a primary refrigerant in cooling, refrigeration, and freezing applications, preserving the flavor and texture of food products by maintaining precise thermal control. It also reduces the need for preservatives in packaged foods and is essential for carbonating beverages.

☑ Welding & Metal Fabrication:
CO2 is often used alongside argon as a shielding gas to prevent atmospheric contamination during electric arc welding, particularly in metal fabrication and construction.

☑ Chemistry:
In synthetic chemistry, CO2 is used to control reactor temperatures and in processes like supercritical fluid extraction. It neutralizes alkaline wastewater and is critical for various chemical synthesis applications.

☑ Medical & Healthcare:
Carbon dioxide is utilized for inerting, chemical synthesis, supercritical fluid extraction, and pH adjustment of wastewater. In healthcare, it supports the operation of artificial organs and serves as a respiratory stimulant in oxygen or air mixtures to promote deep breathing.

☑ Metal Industry:
In the metal industry, CO2 plays a vital role in environmental protection. It suppresses smoke during exhaust and carbon charging, reduces nitrogen absorption during EAF extraction, and is used for bottom stirring in steel production. In non-ferrous metallurgy, CO2 prevents fumes during the transport of matte and ingots.

☑ Laboratory & Analysis:
Supercritical CO2 is utilized as a mobile phase in chromatography and extraction applications, offering versatile capabilities in laboratory settings.

☑ Pulp & Paper:
CO2 enables precise pH adjustment in recycled pulp or chemical pulp after alkaline bleaching processes, supporting efficient paper production and recycling.

This versatile gas is indispensable across various industries, contributing to efficiency, safety, and environmental sustainability in numerous applications.
