Success Stories

ITI-Energy a world leader in the field of creating energy from waste had a dilemma. That to create a gas suitable for use as fuel for combustion engines it first has to be cleaned. This is achieved by scrubbing the gas with water, but the oil, tars and particulates have just been transferred from one carrier to another. The normal way of oil and tar removal from water is by the use of chemicals which create a waste that is only suitable for land fill and the whole object of creating energy from waste is to avoid landfill and its pressures on the environment.

ITI-Energy contacted Comocri Ltd who like themselves was based at the Innovation Technology Centre near Sheffield. Comocri Ltd decided that the best approach to the problem was instead of trying to reinvent the wheel it would search for equipment that performed a similar function in another industry and could be modified to suit ITI’s needs. The basis of the solution was found close at hand. Comocri Ltd had a close relationship with a major industrial concern called MAHLE, a major player in the automotive and filtration sectors. MAHLE had just recently prior to ITI’s request completed the purchase of another German company called Norddeutsche Filter Vertriebs (NFV) GmbH who are world leaders in the design and construction of maritime bilge water cleaning systems. NFV were used to de-oiling of shipborn water down to limits as low as 5 parts per million to conform with the latest maritime legislation. Comocri Ltd decided to use NFV’s equipment as a basis for ITI’s requirement and a test unit was manufactured in Germany in a new modular form that would allow for other facets to be introduced to the system as each application merited.

The unit was trialled at ITI’s trial gasification unit based at Morecroft Engineers premises in Sudbury. The fuel used was pelletized RDF (Refuse Derived Fuel) and to put the performance in a nutshell “It Did Exactly What It Said On The Tin” The Hydrocarbon elements had been reduced from 46 mg/ltr to a staggering 0.4mmg/ltr the impact on the particulates and heavy metal content was of an equal performance. A full analysis of the inlet and outlet of the liquid is available by clicking on the link below. Although the discharge from the unit appeared to conform to all aspects of the Waste Incinerator Directive we would advocate the use of one of our other modules should heavy metals be present in Sulphate or Colloidal form. A full sized unit of 10m3 has been commissioned by ITI-Energy for installation at the Caithness Heat and Power wood burning gasification plant based at Wick Scotland.
