What is co2 generator?

carbon-dioxide-generator
Co2 generator is a laboratory instrument that uses an irreversible chemical reaction of strong acid and strong base to produce Co2 gas. Since the two materials, strong acid and strong base, react violently and produce heat-absorbing reactions, and the release of carbon dioxide is a heat-absorbing process, the resulting carbon dioxide gas has the characteristics of low temperature and high pressure.

Working principle of co2 generator

The reaction equation is as follows.
H2SO4 + 2NaHCO3 → Na2SO4 + 2CO2 ↑ + 2H2O

Carbon dioxide generator tanker is the main body of the reaction, with concentrated sulfuric acid in the upper jacket and sodium bicarbonate mixture at the bottom. The two substances are connected through the valve pipeline, and the gas production function can be realized by opening the valve during the reaction to accelerate the reaction. A reaction stirring device is set to realize rapid gas production. The function of the sodium bicarbonate mixing and stirring tanker is the preparation and delivery of two chemical substances. It adopts underground explosion-proof three asynchronous motors to drive the sulfuric acid pump to realize the automatic transfer of concentrated sulfuric acid to the carbon dioxide generator tanker. The stirring device is driven by an explosion-proof triple asynchronous motor under the coal mine to achieve the stirring of sodium bicarbonate and water. Automatic transfer of sodium bicarbonate mixture to the carbon dioxide generator tanker by using an underground explosion-proof triple asynchronous motor to drive a sodium bicarbonate mixture feeding pump.

Feature of co2 generator

a. High degree of automation with 4 kinds of automatic ways. Double automatic feeding of concentrated sulfuric acid and sodium bicarbonate. The reaction is accelerated by an automatic stirrer to ensure a fast and thorough reaction. Automatic stirring of sodium bicarbonate and water to ensure uniformity of raw materials and non-clogging transport.

b. One tank-type reaction structure. Sulfuric acid container and ammonium bicarbonate raw material react in one tank. The size and weight are smaller and lighter compared with similar products.

c. Combination of automatic and manual is adopted. Both automatic loading system and manual mode are provided to ensure manual operation in case of no electricity.

d. The operation process is non-hazardous and does not produce harmful gases such as CO, and the temperature of the generated CO2 is low.

e. Large CO2 flow rate, up to 1000m3/hour.

Advantage of co2 generator

a. Easy to use. The equipment is easy to operate, safe and reliable.

b. Low cost. Cost-effective and cost-saving.

c. Durable. The main structure is made of high-quality stainless-steel material, which has the characteristics of exquisite appearance and non-rust corrosion.

Co2 cylinder and Co2 gas generator

co2-generator-system

Carbon dioxide cylinder

Carbon dioxide cylinder is a pressure vessel. In a hot environment or by impact, if its pressure exceeds its own withstand limit, it will explode. The explosion will open the safety valve, resulting in gas leakage.

When using carbon dioxide cylinders, the ambient temperature should not exceed 30 degrees. Do not fill more than 70% of the volume of the cylinder itself, and do not place it upside down or horizontally.

Carbon dioxide cylinder precautions

a. Cylinders should be stored in a cool, dry place, away from heat sources, such as sunlight, heating, and fire. The temperature should not exceed 30 degrees, so as to avoid the formation of high-pressure gas from the temperature rise of liquid CO2 and the danger of explosion.

b. Cylinders should not be placed lying down. If the cylinder is lying down, when the pressure reducing valve is opened, the CO2 liquid will be rapidly vaporized, which will easily lead to the bursting of the gas tube and the accidental leakage of a large amount of CO2.

c. The pressure reducing valve, connector, and pressure regulator device should be connected correctly, and there is no leakage, no damage and in good condition.

d. CO2 should not be filled in excess. The filling volume of liquefied CO2 should not exceed 75% of the cylinder volume in a temperate climate and 66.7% in a tropical climate.

e. Old cylinders are regularly inspected for safety. When the cylinder is over the age of safety norms, it should be qualified by a pressure test before it can continue to use.

Co2 gas generator

Although it is not difficult to obtain CO2 cylinders, there are many obvious advantages to using a CO2 generator compared to using cylinders. The use of carbon dioxide generators eliminates the safety hazards associated with the handling of cylinders. Gas co2 generators are very cost-effective. According to many users' feedback, the cost of the gas generator can be recovered in as little as one year. Once the gas generator is connected to the mass spectrometer and supplied with gas, the probability of contamination of the mass spectrometer by the nitrogen source is greatly reduced. However, if the user uses CO2 cylinders, there is a high probability that foreign contaminants will enter the detector during the cylinder change and contaminate the detector.

b. Energy efficient.
c. Environmentally friendly.
A large amount of energy is consumed during gas extraction, cold filtration and distillation, pressurization and handling.

Comparison of Co2 gas generator, cylinder, and liquid nitrogen tank

Carbon dioxide gas supply methodCylinderLiquid nitrogen tankGas generator
ReplacementFrequent ordering and replacement requiredFrequent ordering and replacement requiredNo need for replacement
Volume and appearanceCompared to liquid nitrogen tanks are more compact, and need to be fixed upright when placed.Large volume and heavy weight make transportation and handling difficult.Specially designed for laboratory. Compact and easy to place, it can be placed under the lab bench. Wall-mounted carbon dioxide generator is available.
High temperature and high-pressure gas storagePotential safety risks during transportation and storage with cylinder pressure up to 150 bar.The temperature of liquid nitrogen is -196℃, which poses a potential safety risk when transporting and storing.No high-temperature and high-pressure gas storage.
Gas supply continuityAccording to the cylinder capacity gauge pressure indication, gas cylinders need to be ordered and prepared in advance to ensure that there is no impact and loss of continuity of the analysis.Liquid nitrogen tanks are often used up without obvious warning, so users need to store a tank of liquid nitrogen in the lab.On-demand production with 24/7 continuous gas supply.
Gas source stabilityCylinders are prone to purity differences.The liquid nitrogen tank will be automatically deflated in stages to reduce pressure protection, resulting in unnecessary waste of gas.Stable and safe operation with only annual maintenance of some filter components.
CostThe price of the cylinder includes the cost of renting the cylinder and purchasing the gas. The price fluctuation is large and the cost is less controllable.The price of a liquid nitrogen tank includes the cost of renting the tank and purchasing the liquid nitrogen. Large price fluctuations, large regional differences, and poor cost controllability.One-time investment with cost recovery in about 3-5 years. Higher cost controllability.
