WVO Filter VS WVO Centrifuge

First what are these two types of filtering systems?

WVO (waste vegetable oil) centrifuge:

A centrifuge is a piece of equipment, generally driven by a motor that puts WVO in rotation around a fixed axis, applying a force perpendicular to the axis. The oil entrifuge works using the sedimentation principle, where the centripetal acceleration is used to evenly distribute substances (WVO) of greater and lesser density. Traditional centrifuges use an electric motor to spin a bowl at high RPM and create a force like gravity but up to 3000 times the force of gravity. This speeds up partical and water separation enormously. Separation levels that might take months using only gravity take less than a minute in a centrifuge. And most industrial centrifuges are continuous so dirty WVO can be fed in and clean/dry WVO fuel exits. accumulatMost centrifuges must be stopped to remove the contaminants but some systems are available that allow automated cleaning without stopping the centrifuge.

WVO (waste vegetable oil) Filter:

A gravity or pressure filtration system, the WVO is simply poured into a filter bag placed over a container into which the WVO is collected. These filter bags come in different microns or levels of filtering ability to fit your needs.

Which is better well it all comes down to how much WVO you want to process, how much time you have to spend processing how much money do you want to spend and how hard do you want to work.

With WVO Filter system Oil will run through a 100 micron filter bag at 2-5 gallons per minute however, if the oil is dirty or just creamy the flow rate will deteriorate rapidly. Pre-heating the oil helps as does larger/longer filter bags.  My advice is to only use filter bags after settling. This means time waiting for the oil to settle. Cartridge WVO filters, tee strainers ECT, should be used only with heated oil or heating of the filter.Waxy particles in cool oil quickly clog cartridge filters and no amount of pressure will resolve this issue. Any mechanical cartridge filter will require an amount of pressure to work, finding an appropriate pump, plumbing and pressure relief system can be difficult and large spills are possible.

ith WVO Centrifuge Forced Settling can clean WVO to sub micron levels as well as removing heavier liquid contaminants such as water.f you are looking at having to deal with hundreds of gallons or more a centrifuge is your only solution. A WVO centrifuge is required to remove solid and liquid contaminants from the WVO regardless of size. Centrifuges have proven to be quite efficient in the cleaning of waste vegetable oil and reducing the free fatty acids in the pre-processing of Biodiesel. They also have proven to remove glycerin during the processing. Contaminant particles as small as 1/10^th of 1 micron are removed, all without the use of a disposable costly filter element. There is no better way to make quality biodiesel quickly. What takes many hours for gravity to separate down; a centrifuge can separate instantly in seconds.

 

The Benefits of Conversion from Diesel to Biofuel (WVO)

ue to unstable oil price situation in the world market, many countries have been looking for alternative energy to substitute petroleum. Researches on the use of waste vegetable oils (WVO) as fuel substitutes in diesel engines have been done in many countries with much success.
Biofuel is diesel fuel that is made by reacting waste vegetable oil (WVO) with other common chemicals. Biofuel may be used in any diesel automotive engine in its pure form or blended with petroleum-based diesel.
Biodiesel is nontoxic and biodegradable, that it can help reduce dependence on foreign oil and cut down on greenhouse gas emissions. It’s an oxygenated fuel, so it burns more completely than other fossil-based products. Filling your car with biodiesel cuts down on emissions of unburned hydrocarbons, carbon monoxide, sulfur and the nastiest of all diesel byproducts–particulate matter.
Cars built since 1994 that are already equipped with diesel engines can run even 100 percent biodiesel with little or no modification. Some work will be needed to run on pure vegetable oil, but you may be able to do it yourself.
The energy content of a given amount of waste vegetable oil is only a little less than that of diesel fuel, and is more than for gasoline. Therefore, power and fuel economy on WVO is almost the same as on diesel. Under most conditions, there is little or no perceptible difference to the driver between driving on diesel and driving on WVO.
WVO system reliability has improved greatly in a short period of time. The growing base of WVO users have contributed their knowledge to that gained in production and sale of systems.
Biodiesel is a natural fuel system lubricant. Independent studies by Stanadyne Automotive Corp. and Southwest Research Institute show biodiesel improves the wear or scarring of metal parts within the fuel system.
The flash point (the point at which fuel ignites) for biodiesel (B100) is a minimum of 300 degrees versus about 125 degrees Fahrenheit for regular petroleum diesel #2.
Biodiesel is also non-toxic and biodegradable. These factors make biodiesel one of the safest fuels to use, handle and store.

Waste Vegetable Oil or (WVO)

There is a lot of information about vegetable oil and how it is made, its use from the time it is processed to the time it is considered as a waste product. Usually the point it becomes a waste product is when it leaves the fryer. But is that the end of its serviceable life some say no there is an increasing interest to use this waste oil as fuel, biodiesel and biofuel.

How is waste vegetable oil or (WVO) made into fuel? First all this needs to be done at room temperature (70 degrees F) you need sodium hydroxide (lye), methanol (Heet), and vegetable oil. Adding these three ingredients together in correct quantities and mix them until they are completely blended. At this point, you let the mixture settle and it will separate into layers where the bottom layer will be the glycerin and the top layer the biodiesel.

The process above was with clean oil but what about the oils and grease from fryers grills etc. what to do when you have old oil that isn’t very clean ? Well at the start of the process you need to filter the oil there are many ways to do this Bag filters are the easiest, cheapest and slowest processing tool that you have other than strait settling to process WVO . Oil will run through the 100 micron filter bag at 2-5 gallons per minute however, if the oil is dirty or just creamy and the flow rate will deteriorate rapidly. Pre-heating the oil helps as does larger/longer filter bags . You can use filter bags after settling, but the best advise is to use the centrifuge to get more precision process.

Cartridge WVO filters, tee strainers ECT, should be used only with heated oil or heating of the filter.  Waxy precipitates in cool oil quickly clog cartridge filters and no amount of pressure will resolve this issue.  Reserve cartridge filters for final polishing/filtering at transfer into the vehicle or very low volume/emergency use.   Any mechanical cartridge filter will require an amount of pressure to work, finding an appropriate pump, plumbing and pressure relief system can be difficult and large spills are possible.

Another way is to use what I call “Forced Settling” WVO centrifuges can clean WVO to sub micron levels as well as removing heavier liquid contaminants such as water.  If you are looking at having to deal with hundreds of gallons or more, a centrifuge is your only solution.

You probably don’t stop to think about it, but all fuels have a shelf life that depends on their chemical composition and storage conditions. The chemical stability of biodiesel depends on the oil from which it was derived. Biodiesel from oils that naturally contain the antioxidant tocopherol or vitamin E (e.g., rapeseed oil) remain usable longer than biodiesel from other types of vegetable oils. Stability is noticeably diminished after 10 days and the fuel may be unusable after 2 months. Temperature also affects fuel stability in that excessive temperatures may denature the fuel.

 

Running a Diesel Car on a Used Cooking Oil

It is known throughout that diesel engines were originally designed to run on vegetable oil and to the mechanical and technical person, the diesel engine was invented by Rudolf Diesel. He was the one who came up with the idea of combusting engine using a vegetable oil. In the modern times, not all engines are equipped to use vegetable oil as fuel without some additional processing or conversions.

To be able for any ordinary diesel engine to accept vegetable oil, WVO centrifuges and filters were created to help in the conversion process. To convert the vegetable oil into a biofuel, one has to simply heat the vegetable oil in the tank or fuel lines before it is injected directly to the engine. An extra tank is needed for this process, a heater system for heating it and a filter to avoid clogging. Filtration can take weeks, but there is another way to maximize the filtration process, and that is by the use of WVO centrifuges.

A common way to do it is to start your engine using the petroleum-based diesel fuel for a certain time until the vegetable heats up. Getting the right temperature will automatically get the engine to switch to the vegetable oil as fuel. Once the car is switched off, the engine will switch back to the standard diesel to clear the fuel lines of vegetable oil preparing for the next time it is going to be used.

Climate is an obstacle to using vegetable oil, so it is best to heat the vegetable oil properly as it may harden. The key to this is to have the vegetable oil in liquefied form to flow smoothly in the fuel lines.

Of course there are other ways of running your car using vegetable oil. Best to have your engine converted into a vegetable oil ready. It may cost some money, but the cost of conversion is far outweighed by what you can save using vegetable oil.

So where can you get vegetable oil? Easy, you can get them from your own kitchen or in restaurants and food manufacturers. All you need is a good filtration equipment and voila! You are ready to go!

The Power Generated from Waste Vegetable Oil

We all know that Waste Vegetable Oil can be converted to Biodiesel. To get the total understanding of what a biodiesel is, this refers to a non-petroleum-based diesel fuel that consist of short chain alkyl esters (methyl or ethyl) through the process of transesterification of the vegetable oil or animal fat which can either be used alone or blended together with conventional petrodiesel in unmodified diesel engines.

Biodiesel is distinguished from the straight vegetable oil (SVO) used as fuels in some converted diesel engines.

How biodiesel was discovered and where… goes back to 1937 in Belgium. It was discovered by G. Chavanne of the University of Brussels when they were performing the procedure for the transformation of vegetable oil for their uses as fuels.

There are many uses for biodiesel. It can either be used in its pure form or can be blended with petroleum diesel as what we have stated above, at any concentration in most modern diesel engines. Biodiesel has different solvent properties than petrodiesel and will degrade natural rubber gaskets and hoses in vehicles (mostly the ones manufactured before 1992). One thing about biodiesel is that it has been known to break down deposits of residue in the fuel lines where petrodiesel has been used.

Biodiesel is distributed globally. Their sources are everywhere – you can get them in your own homes, local markets, restaurants and in food manufacturers. Waste Vegetable oil is the way to go for a healthy and clean living; as well as being cost-effective it really is the best alternative fuel.

There are a lot of resources there concerning WVO. Be part of raising awareness to the uses of waste vegetable oil.
