PCO2 Series Purifiers

Parker Domnick Hunter PCO2

Carbon dioxide pollution can occur both due to the initial presence of mixture in the process of receipt and as a result of their appearance during transportation and storage. Carbon dioxide, which is used in the food industry, must necessarily be cleaned. In the countries of the European Union, the generally accepted documents for determining the carbon dioxide quality standards are:

• CO2 Quality Guidelines, developed by the International Society of Beer-free Technologies (ISBT),
• “G-6.2 commodity specification for carbon dioxide” (G-6.2 commodity specification for carbon dioxide), developed by the Association of Compressed Gases (CGA),
• Carbon dioxide - sources, certification, quality standards and validation methods (Carbon Dioxide Sources, Certification, Quality Standards and Verification) is a document of the European Association for Industrial Gas Use (EIGA).

 To determine the adequacy of carbon dioxide for use in the food industry, the limit standards of content of certain groups of substances and individual chemical compounds that have the most negative impact on the taste and aromatic quality of products as well as their appearance are adopted. The table below shows certain ISBT limit-admissible concentrations of these substances in the food carbon dioxide (Jerello: ISBT CO2 quality and analytical procedure, 2001).

In response to the growing demand for food carbon dioxide quality, Parker Domnick Hunter has developed a line of carbon dioxide cleaners PCO2 series. Working as a thin adsorption system of gas-like mixture, PCO2 cleaners allow to bring unwanted carbon dioxide compounds to the highest quality standards.

What is the industrial air cleaning machine?

 PCO2 series carbon dioxide cleansers are five-step carbon dioxide cleansing systems consisting of:  
- a fine inlet filter that removes non-volatile contaminants with particle sizes from 0.01 μm (shown as item 1 in the diagram above),  
- three-step adsorption system of flying houses with carefully selected adsorbents, inserted in variable cartridges for the convenience of replacement (on scheme - 2, 3 and 4),

- and the output filter that removes possible adsorbent powder (on scheme - 5)

Three layers of the adsorbent preferably remove unwanted houses from the gas flow. The below table shows the distribution of the load from removing certain houses between the layers and the adsorbent properties of each of the layers in relation to the specific houses:

The table will distribute the removal of the houses in the industrial air cleanser.
