FAQs

What is Eco2pure™?
Eco2pure™ is a unique dry wash formulation of adsorbent technologies specifically designed for the removal of post-reaction contaminants and production residues resulting from the biodiesel production process ie transesterification

What makes Eco2pure™ so unique?
Eco2pure™ is a natural and sustainable biodiesel purification media, which boasts one of the lowest purification costs per litre/gallon on the market today. Eco2pure™ is proven to assist in the attainment of EN/ASTM quality standards.

Are the Eco2pure™ Treatment Towers available loose?
Eco2pure™ Treatment Towers are available loose for producers to configure as they like or as part of an Eco2pure™ System.

What is an Eco2pure™ System?
Pumps, control panels, safety features are all configured to achieve maximum media life, production throughput and fuel quality.

Is water washing still required?
No, Eco2Pure™ can also completely replace traditional, outdated water washing methods  

Is any filtration required?
There is no filtration required in the wash stage, however as with all purification methods, final polishing is recommended.

How often does media need changing?
Each kg of Eco2pure™ is capable of purifying 300-600 litres of biodiesel, making it one of the most cost effective methods of purifying biodiesel. This is assuming the necessary good practices are adhered to upstream. The life of the Eco2pure™ media depends on:
- the quality of the incoming biodiesel
- the flow rate
- the size of the media bed

Is this an expensive system to operate?
No, Eco2pure™ is one of the lowest cost methods of purifying biodiesel.

How do I determine when the media is exhausted?
There are several ways to detect when the media is exhausted and can no longer adsorb impurities into the media. The most effective method in terms of accuracy and cost, however, is pH indication which offers adequate warning to the producer that the media bed is spent.

Can you offer any Tower housing design recommendations?
The tower design should be configured to facilitate the loading and unloading of the media into the tower, as well as to ensure tight media bedding. Flow rates need to be controlled to ensure maximum contact time with the media, and the internal sealing arrangement needs to be specified correctly in order to prevent downstream migration of the media.

What flow rates are required?
Flow rates depend on the size of the media bed. Whereas Eco2Pure™ can accept a higher flow rate that competitor dry wash purification systems, it is important that sufficient contact time is allowed for the Eco2pure™ media to perform its function.

A general guideline for the correct flow is:
2kg bed: 3 l/min
10 kg bed: 5 l/min
50 kg bed: 9 l/min

What tower size do I need?
The size of the tower and the capacity of the Eco2pure™ media bed is determined by the desired production capacity of your facility. The tower size will not effect media consumption or operating cost. The larger the tower, the less frequently the media bed will need replacing.

How can I increase the flow?
Should you wish to increase production levels, additional towers would be required and can be connected in a parallel flow arrangement.

Do I need to pump the biodiesel through the media or is gravity feed an option?
For smaller production volumes, gravity feed can be used, but this may not be an a viable option for the commercial producer. By pumping the biodiesel through the media at a set flow rate, your process time can be better controlled.

How do I remove the spent media from the tower?
This process is best performed using compressed air to remove the spent media bed

How much Eco2pure™ should I load in the tower?
Depending on the media holding capacity of the tower, the media should be loaded and compacted as tightly as possible within the tower. By loading the media all the way to the top of the tower, the media bed size and life are maximized. Retaining plates are advised to secure the media bed into place.

Does the Eco2Pure™ media swell/expand within the tower?
No, once the media is placed into the bed it does not swell, which allows for maximum space utilization of the towers.

How does the loading/bedding procedure work?
The Eco2Pure™ media is loaded into the top of the tower and compacted within. It is important that the bed is loaded as full as possible to ensure no movement during operation.

What temperature do I operate at?
Eco2pure™ will offer excellent results at ambient temperatures, as well as higher temperatures of 90°C. 40°C, however is the optimum running temperature.

Do I need to remove the methanol before use?
Effective phase removal will enhance the media performance and extend media life.

What are the packaging options?
Eco2Pure™ is packaged in airtight, sealed 15kg bags. This is intended for easy handling and storage.

Are the any storage issues?
Eco2pure™ should be stored in a cool, dry location.

How do I disposal of the spent Eco2pure™?
Eco2pure™ is non-hazardous and has a wide range of uses for the spent media.

Is there any way of optimizing the performance of Eco2pure™?
Yes. Eco2pure™ media may spend prematurely if the free methanol is still present, it is recommended that methanol removal is carried out prior to Eco2purification.

In what sizes are Eco2pure™ treatment systems available?
Standard versions of Eco2pure™ towers are available in 2 kg, 10 kg and 50 kg. Larger housings are available on request

What quality systems can be incorporated into Eco2pure™?
Eco2pure™ is compatible with particle counting technology which makes Eco2purification interactive via your PC or Laptop. Particle counts generate ISO4406 contamination codes which are taken in real time and logged using Microsoft Excel. It is also recommended to use zero-cost, in house quality checks such as simulating a mini wet wash and using pH testing to determine the purification process is complete to a satisfactory level of assurance. These are in-house quality control procedures that should be used in addition to laboratory analysis
