Liquid CO₂ Production Equipment

Product Overview
Liquid carbon dioxide (CO₂) is a major byproduct generated during the fermentation process of alcohol production, with concentrations exceeding 99% in the fermentation gas. This high concentration presents significant utilization value. With simple purification processes, it is possible to obtain high-purity CO₂. Our company has successfully designed high-purity CO₂ recovery systems for numerous alcohol plants both domestically and internationally, yielding substantial economic benefits. As the national economy grows and living standards rise, the demand for carbon dioxide in the market has been increasing year by year, with purity requirements also becoming more stringent.

Product Features

• High Recovery Efficiency: Approximately 0.95 tons of CO₂ can be recovered for every ton of alcohol produced, with actual recovery rates ranging between 50% and 70%.
• Significant Economic Benefits: The production cost for one ton of CO₂ is about 180 RMB, primarily comprising electricity and water costs.
• High Purity Products: The produced liquid CO₂ meets food-grade standards and is widely used across various sectors including food, industry, agriculture, tobacco, and pharmaceuticals.
• Mature Processing Technology: Utilizes processes such as strong oxidative solution washing, low-pressure compression, drying, and temperature/pressure swing adsorption to ensure low impurity content in the gas.
• Automated Control: The PLC automatic control system optimizes equipment operation, enhancing operational efficiency.

Applications

• Food Industry: Used in beverages, beer production, and welding protection.
• Agriculture: Serves as a greenhouse gas to enhance crop yields.
• Industry: Acts as an essential raw material in chemical and pharmaceutical industries.
• Tobacco Industry: Utilized for tobacco processing and preservation.
• Oilfield Extraction: Employed in CO₂-enhanced oil recovery and extraction.
