Whey Protein By-Product Value Generation

By |2020-07-01T15:50:01+00:00April 13th, 2020|Architecture|

Background Whey is a by-product of the dairy industry with its main component being whey protein.  Benzoil’s GrainOut business unit specialises in the niche area of value added product creation.  GrainOut has identified alternate opportunities to reusing whey protein as a liquid animal feed in Australia. Whey is the liquid by-product remaining during cheese

Food By-Product Removal

KNAN, KNAF, ONAN, ONAF – what do they mean?  Here’s how to unlock the cooling class code for liquid filled transformers. The ANSI/IEE Standard C57.12.00 defines a 4 character code to describe the cooling attributes of the transformer.  The first letter refers to the main cooling medium (i.e. in contact with the windings).  Decode as

Oil For Any Transformer

Whether the insulating fluid be mineral oil, vegetable oil (esters) or synthetic, we can supply the product to match the need. Just as oils vary in design, transformers themselves are abundantly different – many with similar properties and some quite specialised and unique.  Here are some of the electrical transformers for which can supply dielectric

5 Reasons Why You Are Paying More For Transformer Oil

By |2020-04-20T13:40:14+00:00September 28th, 2018|Architecture|

Transformer oil pricing in the Australian market has been relatively stable for some years, but recently with oil prices more widely increasing so has pricing for transformer oil.  Factors that influence the price we pay for any oil product in Australia are the Australian currency, the barrel price for oil, market expectations, and supply and

Purity And Chemistry of Transformer Oil

By |2018-10-16T03:49:55+00:00August 28th, 2018|Architecture|

The quality or performance of electrical insulating oil is dictated by its chemical structure.  Chemical structure determines the consistency of its viscosity performance, it resistance to oxidation (longevity of performance) and its compatibility with other materials. In addition to chemistry, the purity (moisture content and impurities) of the oil also influences many of the oil

Naphthenic versus Paraffinic

By |2018-07-10T04:01:03+00:00July 9th, 2018|Architecture|

Naphthenic versus paraffinic oils – which is better? The answer is not so straightforward because the application will drive the choice of oil. In the case of transformers there is a lot more historical data and knowledge on naphthenics than on paraffinics, and naphthenic oil has traditionally been considered the gold standard. However paraffinic oil

Silicone Transformer Oil

Mineral oil is by far the most abundant transformer fluid in use in Australia.  There are however other options, which do have their place in specific transformer applications including chlorinated hydrocarbons (e.g. PCB which is banned), high molecular weight hydrocarbons, biofluids, esters, and silicone fluids. Silicone fluids or more correctly polydimethylsiloxane (PDMS) are a type

PCB Oil Disposal And Transformer Decontamination

Many proud electrical asset managers will proclaim that their fleet of transformers is PCB-free, yet although they have worked long and hard to achieve this outcome some PCB oil still resides in their system.  In our experience most electric utilities in Australia have methodically surveyed their transformer fleet (power transformers anyway) and maintain dedicated registers
