Product Overview
Fuel combustion technology for producing food-grade carbon dioxide utilizes carbon-containing fuels such as natural gas or diesel to generate high-concentration CO₂ gas.
Through low partial-pressure absorption, desorption, and purification processes, the system enables stable production of food-grade CO₂. It can deliver over 50 kg/h of CO₂ in either gaseous or liquid form. The liquid form facilitates easier storage and transportation, and the product format can be flexibly adjusted to meet the requirements of different industries.
Working Principle
The technology begins by combusting carbon-based fuels to produce CO₂-containing gas. After pretreatment, the gas enters an absorption system where CO₂ is selectively absorbed using a low partial-pressure process and a novel biphasic absorbent.
The saturated absorbent is then heated to desorb high-purity CO₂, which undergoes multi-stage purification to remove impurities such as sulfur compounds and nitrogen oxides. Steam generated during combustion serves as the heat source for the desorption tower, enabling energy recycling and efficient operation. The final product meets food-grade CO₂ standards and can be supplied in gaseous or liquid form.
Key Features
- High-Efficiency Absorption: Low partial-pressure recovery combined with biphasic absorbents increases absorption capacity by approximately 25%.
- Energy Saving: Overall energy consumption reduced by about 30%, using combustion steam as a heat source for regeneration to lower operating costs.
- High-Purity Product: Effectively removes sulfur compounds, nitrogen oxides, and other impurities to ensure CO₂ purity and safety.
- Stable Liquid CO₂ Output: High-precision filtration ensures consistent quality for liquid CO₂.
- Flexible Supply: Can deliver CO₂ in either gaseous or liquid form to suit various application and storage needs.
Applications
- Beverage Industry: Provides food-grade CO₂ for carbonated drinks and related products.
- Food Processing: Used in food cooling, preservation, and modified atmosphere packaging to improve quality and safety.
- Chemical Industry: Serves as a raw material or intermediate medium in various chemical production processes.
