FAQ 01

CO2 Compressor

The CO2 compressor is a two-stage, oil-free piston compressor mounted on a frame, which is equipped with an independent intercooler and an aftercooler and an automatic condensate drain system.

At the same time, the compressor load control device is controlled depending on the filling status of the gas container.

The main components include:

  • Two-stage, oil-free piston compressor
  • Cooler
  • Automatic condensate drain system
  • Safety valves, oil pressure switches
  • High and low pressure safety switches
  • Temperature sensors

FAQ 02

Activated carbon filter, H2S filter

The adsorption filter consists of two parallel adsorption towers filled with activated carbon or H2S adsorbent.

The parallel adsorption towers are automatically switched between operation and regeneration using pneumatic valves, solenoid valves and PLC. 

The activated carbon filter removes sulfides, ethanol and odor. The filter with H2S adsorbent provides additional ultra-deep and ultra-fine purification to ensure food-grade CO2 parameters. 

Two towers operate alternately: one adsorption tower operates while the other is being regenerated. 

Adsorption towers are installed on racks and consist of:

  • Adsorption tower housing 
  • Adsorbent (activated carbon) or H2S adsorbent
  • Pneumatic ball valve
  • Manometer
  • Electric heater
  • Electric contact thermometer

FAQ 03

Drying unit

The drying unit consists of two parallel tower bodies with drying agents inside. The two-tower structure automatically switches between operation and regeneration periodically, with one tower operating while the other is regenerating. The dryer removes moisture from the CO2 gas (using molecular sieves or activated alumina), and the CO2 after deep drying has a pressure dew point of -60℃. 

The molecular sieve is heated by an electric heater during regeneration, and the CO2 enters the activated carbon after blowing out of the dryer. The regeneration gas is regenerated using the non-condensable gas from the CO2 condenser. The dryer and adsorber use electric heating for automatic operation.

The drying unit includes: 

  • Two drying towers with uniform gas distribution 
  • Pneumatic ball valve
  • Manometer
  • Electric heating device
  • Flow regulator
  • Gas filter 
  • Molecular sieve or activated alumina packing

FAQ 06

CO2 Evaporative Condenser

CO2 evaporative condenser is a shell-and-tube heat exchanger. 

The shell-and-tube heat exchanger contains CO2 gas, and the tube-and-tube heat exchanger contains R507A refrigerant, which is supplied by the refrigeration unit. The R507A refrigerant, compressed by the refrigeration unit, expands through an expansion valve into the tube section of the CO2 evaporative condenser, where it absorbs heat and evaporates. 

The inclined evaporative condenser is equipped with an automatic CO2 discharge system with a timer, which effectively discharges non-condensable gases such as O2 and N2, ensuring complete purification. 

CO2 absorbs cold energy in the shell-and-tube section and liquefies. The liquefied CO2 enters the liquefied CO2 storage tank. 

The main components include:

  • CO2 evaporative condenser
  • Pressure and temperature gauge
  • Fittings
  • Expansion valve
  • Shut-off valve

Analysis of raw or unpurified gas

For the correct design of the equipment and the purification process, the first step is the analysis of the raw gas. We perform an extensive list of analyses of the raw CO2 gas to prevent any "surprises" after the launch of our projects. We carry out the analysis in our German laboratory according to this list of parameters.

About ecology

Carbon dioxide recovery (recovery) is a modern and environmentally responsible approach to reducing atmospheric emissions. Significant amounts of CO₂ are generated during the production of food, beverages, biogas, or fertilizers. Without proper disposal, it enters the environment and increases the greenhouse effect.

Thanks to recovery technology, this gas is not emitted but reused in industrial and food processes. This allows:

- to significantly reduce greenhouse gas emissions;

- to reduce the company's carbon footprint and meet high standards;

- to conserve natural resources by reusing already produced CO₂;

- to make production more environmentally responsible and sustainable.

CO₂ recovery is not only an economic benefit, but a tangible contribution to the fight against climate change and preserving clean air for future generations. It is a technology that benefits businesses today and the environment tomorrow.

The Tiz-Karbogaz CO₂ plant implements innovative recovery solutions, helping businesses reduce their carbon footprint and transition to more environmentally friendly production.

FOR BIOETHANOL, BIOGAS PLANTS AND BREWERIES

CO2 recovery is a key process in combating climate change, capturing carbon dioxide emissions from industrial sources before they reach the atmosphere. This CO2 is compressed and either reused in various applications or safely stored, thereby reducing greenhouse gas emissions. 

TIZ-Karbogaz provides assistance in implementing comprehensive CO2 recovery solutions for biogas plants, bioethanol plants or breweries, for anyone interested in reducing CO2 emissions and additionally seeking to increase their profitability.
