FAQ
| Q: | Does Union Engineering's plant produce food grade CO2? |
| A: | Yes, Union Engineering's plants are designed to meet the most stringent quality requirement and will fulfil or surpass requirements set forth in e.g. EIGA or ISBT. |
|
|
|
| Q: | Does Union Engineering plants have CE-marking? |
| A: | Yes, plants supplied to the European Union are all CE-marked. |
|
|
|
| Q: | What types of compressors are used in the CO2 plants for the industrial gases industry? |
| A: | On plants with capacities up to 2000 kg/hr we typically use oil-free reciprocating compressors. For capacities above 2000 kg/hr we typically use oil lubricated screw compressors. |
|
|
|
| Q: | Will the use of oil lubricated compressors create a risk of oil contamination of the final product? |
| A: | Union Engineering's CO2 plants are designed with a highly efficient oil separation system that removes oil to less than the required levels for food grade quality. |
|
|
|
| Q: | Which design standards are used for the design of pressure vessels? |
| A: | Union Engineering will generally supply the plants according to either the European pressure directive PED or American standard ASME. Other standards are available on request. |
|
|
|
| Q: | What type of refrigerant is used on the plants? |
| A: | The most typically used refrigerant on CO2 plants are ammonia. Other refrigerants are available on request. |
|
|
|
| Q: | Can I recover CO2 from landfills? |
| A: | Yes, technically this application is possible. However, as landfill gas contains a broad range of critical impurities that are expensive to remove, production of food grade CO2 from this source will in most cases not be competitive. |
|
|
|
| Q: | Does Union Engineering supply plants for critical extraction? |
| A: | No. |
|
|
|
| Q: | Does Union Engineering supply plants for production of other industrial gases? |
| A: | No, Union Engineering is specialized in CO2 only. |
