The chemical composition of any oil product is a mix of different elements. Here you have hydrocarbons, hydrogen, oxygen with nitrogen, and sulfur. It is clear that the presence of these and other elements is defined by the type of feedstock (petroleum oil), and the method of oil process.

To produce diesel fuel, good for fuel economy,  it is very important to ensure exactly that percentage ratio of components that gives the best possible operating qualities. The main problem is that in most cases there are not entirely useful or entirely harmful elements. Any substance, depending on volume, can alter its chemical effect on diesel fraction.

Let’s take sulfur, for example. Everything seems very clear here. During the combustion of diesel fuel, sulphur promotes sludge deposits, leading to malfunction of engine and fuel system. Environmentalists add that burning sulphur diesel fuel emits noxious gases into the atmosphere.

This state of affairs encouraged European community to solve this problem at the legislative level, strictly regulating sulfur content in their fuels. You probably heard about the brand of fuel “Euro” .

There is, however, another side of the coin. Complete removal of sulfur (for all its downsides) is also undesirable. The absence of this chemical worsens lubricating properties of diesel fuels which in some cases may be crucial. Therefore it is very important to keep a reasonable balance of the percentage of sulphur for practical use.

Cleaning diesel fuel from sulfur – is a difficult task. Depending on the type of oil it can contain many sulfur compounds when converted to elemental sulfur they range from 0.5% to 5%. Oil processing destroys volatile compounds, but they almost immediately react with other chemicals forming new substances. These, for example, may include hydrogen sulfide, which is removed together with other gaseous products by an alkaline wash of hydrocarbon fractions. Interestingly, under certain conditions (temperature, pressure, the presence of a catalyst, etc.) new compounds can again decompose to elemental sulfur.

Petroleum refining industry use so-called hydro-treatment to reduce sulfur content. It breaks down all sulfur compounds forming hydrogen sulfide, the removal technology of which, as of today, is sufficiently developed. There is also an alternative view, offering to remove absolutely all sulfur compounds from fuel, regardless of their chemical composition. Here, too, there are implications. Sulfur-containing compounds in their chemical nature are very diverse. Some contribute to corrosion, reduce the stability of fuel to oxidation and intensify the appearance of resins and various sediments. Other sulfur compounds on the contrary – are non corrosive and have an antioxidative effect. Summarizing the results, we note that new chemical compounds based on sulfur, are still not fully understood, which complicates desulfurization of diesel fuel.

Therefore, in production are often used oils with limited sulfur content or deeply cleaned oils. Sulfur compounds are destroyed by catalytic cracking, hydrogenation, hydrotreating and other methods.

The approaches mentioned above are used mainly in large refineries. So what should small farms or machine and tractor stations do? They too have a problem of desulfurization of diesel fuel. Every owner wants his motor vehicles work effectively as long as possible, and it is only possible when using high-quality diesel fuel. Buying bulky equipment that is used in refineries is very expensive and not economical. Delivering contaminated fuel to the factory for cleaning also does not seem to be an optimal way. Treatment facilities are not always located in close proximity to the farms. In this case, shipping costs exceed the potential benefits. And the small volume of fuels used by autonomous farms is not always suitable for the refinery. It is unprofitable to run a huge installation, which consumes a lot of power for processing a small batch of oil.

A vicious circle? Not really. GlobeCore developed and manufactures UVR installations. They not only reduce sulfur content, but also clarify and restore diesel and heating oil, gas condensate, transformers, industrial, turbine and other oils. Model UVR-450/6 is ideal for fuel economy and purification at small farms, motor companies as well as other economic entities with daily fuel consumption of up to 4000 gallons or oil up to 2000 gallons.

The main advantages of  GlobeCore equipment  are its universality, portability, minimal power consumption, as well as the ability to work in automatic and semi-automatic modes, which helps to minimize human factor in the process.

Owning a business is a way of being self-sufficient and independent, and allows a degree of confidence in tomorrow. However, not all try to start a business, the reasons numerous: lack of starting capital, the risks involve, lack of knowledge in the field and many more. First complications arise at the stage of finding a business idea. One can choose any area for the business, but not all industries will be profitable.

This article deals with one of the possibilities for staring a business. The reader can make a decision whether he or she possesses what it takes to implement the ideas in the articles into real life business.

Causes of diesel fuel contamination

Contaminated diesel fuel: how can it be of profit? There are two points to consider. First, diesel is a popular fuel, used by agricultural and construction machinery, truck fleets etc. Second, the fuel can often become contaminated. To protect themselves from oil product shortages and considering the seasonal nature of their operations (such as agricultural), diesel machinery owners tend to stockpile fuel. Not all fuel is used here and now. Most of the fuel is stored in tanks until needed. This is when the interesting part starts for one looking for a business idea.

In long term storage diesel fuel can become contaminated by dust and water. At certain conditions, microbial contamination is also possible. Using such product is not possible, since the engine and the components of the fuel system are quite sensitive to the various foreign substances. Failure of equipment requires costly repairs and causes downtime, which is always bad, especially so in seasonal businesses.

Hence the need to purify diesel fuel before use. The standard filtration methods most often deal with but a small degree of diesel contamination. If the oil product is heavily contaminated and contains a lot of water, special large equipment is required. Not all own such machinery. Outsourcing the service is also not always an option, since the cost of processing relatively small batches of diesel is rather high.

However, if the contaminated diesel fuel is purchased in large volumes and purified to good condition, profit is there to be made. Contaminated diesel costs significantly less than clean diesel, and this price difference is the way to earn money. The only thing left to consider is the technology process. What kind of equipment should be used?

The best solution is a purification system and a blending system. Getting rid of contaminants is not enough. The product must be made ready for operation by adding special components into the fuel.

Purification and clarification of diesel fuel

Used oil removal of particulate matter, water and other contaminants, reduction of wax and sulfur content, removal of hydrogen sulfide and unsaturated hydrocarbons is the perfect job for GlobeCore’s UVR unit. This unit uses filtration and adsorption to clarify the fuel and bring it back to market quality. After UVR processing, the oil products do not oxidize and darken.

GlobeCore’s equipment can easily be loaded onto a small truck, increasing mobility and providing on-site fuel purification services. It should be noted that the UVR units are multi-purpose and can be used with various oil products, such as heating fuel, mineral oil, gasoline, etc. Transitioning to a different product requires no additional setup, only the processing rate changes.

Adding components

As mentioned above, additive improve performance of diesel fuel. For instance, PPD additives improve pour point and filtration. While operating with large amounts of fuel, special blending systems should be used for injection of additives.

Usual blending methods, in wide use at present, separation of diesel fuel into separate components often occurs. To remove that problem, GlobeCore manufactures the USB type units. By using the injection mixing method and the hydrodynamic shock, the fuel remains stable to separation for at least 180 days.

Modern hydrodynamic continuous blending units have proven themselves in industrial applications to be reliable, precise and stable means of producing high quality motor fuel at optimal cost. The cost economy and increased profitability of the production process compared to the traditional methods of mixing component in tanks can accelerate the return on investment to up to 60% annually and make the project pay for itself within a year.

However, the technology of the process is not everything. Diesel fuel consumers in your area must be researched. This research achieves two goals at the same time: learning where to buy contaminated fuel and who to sell purified fuel with additives to.
