Oil Fundamentals: Crude Oil Grades And Refining Process

To start with, I would like to present credit to Liying Zhao (Options Engineer at HyperVolatility) for helping me to conceptualize this article and to gather the required info to develop it. There might be different articles describing the bodily facet of the crude oil market so this is simply “the first gear of a more complex apparatus

Methanol Recovery ColumnThe present evaluation isn’t a quantitative analysis on the oil market and its goal is to listing the most important elements to consider before investing or trading the black gold. Consequently, the main focus will primarily be on the petroleum physical market and on how the oil trade works. The HyperVolatility group spends a great deal of time analyzing and trading commodity markets, therefore, crude oil positions have at all times had a substantial weight in our portfolio. Also, the nice attention in the direction of commodity markets generated by the credit crunch and the persistently high quantity on crude oil futures and options are a few of the reasons that satisfied us to put collectively a general guideline for those who choose to enterprise into energy markets and specifically fossil fuels.

First of all, it’s worth mentioning that there are virtually 250 several types of crude oils in the world but the ones which are talked about probably the most are primarily 2: the American West Texas Intermediate and the European Brent Blend (which is now the global benchmark).It isn’t unusual to hear financial journalists speaking about different crude oils like the Nigerian Bonny, the Arab Gentle (Saudi) or the Dubai (UAE); nonetheless, the spotlight is nearly solely on WTI and Brent. The explanation these markets, significantly the Brent, have so much media protection is due to their significance when pricing other crude oils worldwide. Once more, the Brent is the nowadays global benchmark (although the WTI used to have this position) so every oil producer or purchaser will have to know its price; the query is why?

Why all other crude oils must be priced in line with Brent value fluctuations?

The reply to this query is API gravity, sulphur content and export.

As we previously mentioned there are many types of crude oils in the world but the chemical composition of every crude grade differs barely. Crude oil is a fossil fuel and it’s fabricated from hydrocarbons (molecules of hydrogen and carbon atoms) but what makes the real difference, in phrases of economic value, is the weight of the hydrocarbons. The rule is simple: the lighter, the higher. In order to find out how heavy or light petroleum liquids are the American Petroleum Institute launched a standardized scale referred to as API gravity. The API gravity system is a standardized means to compare and rank the “lightness or heavinessof diverse crude oils. The system is very simple: the API gravity coefficient measures how heavy or light petroleum liquids are with respect to water. Crude oils with an API gravity greater than 10 are thought of to be gentle (so that they float on water) while oils with API lower than 10 are categorised as heavy (in order that they sink when mixed with water). Crude oils with excessive API values (10 and better) are lighter and produce larger amount of marketable product, therefore, they are extra commercially fascinating. This concept could be higher understood by looking at the following chart (supply: The Worldwide Crude Oil Market Report):

The graph displays the distribution of various crude oils based on API gravity (X axis) and sulphur content (Y axis). It is straightforward to notice that WTI and Brent are each located in the precise – hand aspect of the chart and they are very close to the X axis. The reason these oils are situated in this space is because their API gravity could be very high (which implies they are light varieties of oil) and their sulphur content material is decrease than 0.5% which implies they’re candy (the word “sweetin technical jargon means that there’s a low stage of impurity).

Let’s summarize what has been said up to now:

1) API gravity measures the lightness / heaviness of crude oils

2) API higher than 10 means that the crude oil is mild and more worthwhile in terms of commercial worth

three) API decrease than 10 means that the crude oil is heavy and produces a minor quantity of business product after refining

four) Sulphur content material measures the diploma of pureness of crude oil, the extent of impurity that every crude oil kind comprises

5) Sulphur content material greater than 0.5% indicates a high degree of impurity (bitter crude oil) that must be eliminated

6) Sulphur content decrease than zero.5% implies a low level of impurity (candy crude oil). This situation is most popular because less work is required and the refining course of is faster

7) All the crude oils ranked at the bottom of the correct hand facet of the chart are thought-about to be probably the most engaging beneath a commercial perspective

The aforementioned bullet factors explain fairly nicely why the Brent is among the finest crude oils in the world however why is it higher than the WTI?

The reply is straightforward: the European Brent is exported while the West Texas Intermediate remains throughout the US. Consequently, the WTI has a “minor impacton international markets (in actuality, a part of the Alaskan oil output is exported to Japan and South Korea however the amount is so small to be irrelevant when it comes to worldwide impact).

There are different chemical and physical features that must be talked about when talking about crude oil and one of those is actually viscosity. Viscosity is the “abilityof a specific crude oil or refined product to movement.

Why is this issue important?

The degree of viscosity is essential to determine how crude oil shall be saved or transported which means that the price of carry might be primarily influenced by this variable. Crude oils might be categorized based on their viscosity coefficient:

1) Paraffinic crude oils have low viscosity but they’re Petroleum Refining easily flammable. Most of the engines lubricating oils are manufactured from paraffinic crude oil. Paraffinic oils have a high API gravity and due to this fact tend to be light sorts of crude oil

2) Naphthenic (or Asphaltic) crude oils have a high viscosity coefficient however they aren’t simply flammable. This is the case of bitumen. Naphthenic oils have low API gravity and due to this fact are usually heavy sorts of crude oil

This classification could be very useful as a result of it helps us understand a bit better how the refining process works. Let’s combine all the data together:

– Gentle and sweet crude oils (Brent, WTI, Bonny) have high API gravity, low sulphur content, low viscosity, excessive flammability and therefore are paraffinic oils. Mild and candy crude oils, as soon as refined, have a tendency to provide excessive quantity of gasoline

– Heavy and sour oils (Venezuelan BCF, Russian Urals crude, etc) have low API gravity, excessive sulphur content, excessive viscosity, low flammability and subsequently are naphthenic oils. Heavy and sour crude oils, once refined, tend for use as bitumen feedstock

The refining process goals to separate petroleum liquids in different chemical components which will be subsequently treated and combined with solvents to generate new oil derivatives.

How does the process work?

The crude oil is basically pumped into a furnace and right here the uncooked petroleum releases gases and liquids that are subsequently channeled in a tower to begin the fractional distillation process. The purpose of directing the oil on this tower is to separate or fractionate different chemical components utilizing heat. Particularly, each chemical element could have a particular boiling point and by increasing the temperature each constituent will start vaporizing as soon as its personal boiling level will likely be reached. This process is gradual so the crude oil will fractionate into totally different gases at different temperatures but additionally it is continuous, which implies that new uncooked petroleum liquid will likely be injected into the distillation tower at regular intervals to exchange the fluid that has been already fractioned. The refining process often produces a standardized set of oil derivatives resembling gasoline, jet fuel, diesel fuel and asphalt. However, other merchandise (methane, propane, kerosene, etc) are sometimes distillated. Oil derivatives have a wide range of functions; right here we checklist a few of them:

1) Methane also is aware of as pure gasoline, can be utilized for heating

2) Ethane is normally employed as a feedstock for different production processes (just like the one followed to provide plastic)

three) Propane can be used for both cooking and heating

4) Gasoline is primarily used as gasoline for vehicles

5) Naphtha is one other feedstock and it is usually reused in the petrochemical business

6) Kerosene (referred to as paraffin in UK, Ireland, South Asia and South Africa) is predominantly employed to produce Jet gasoline oil

7) Gasoline oils are used to distillate diesel engine fuels or for house heating

eight) Gas oils are reused to power refineries or energy stations. Alternatively, they are often utilized as a gas for ships but on this case they’re referred to as bunker gasoline or bunker gasoline oil

Now, this info is certainly essential to anyone who is seriously thinking to speculate or commerce oil markets. Oil fundamentals are sometimes neglected however a sound understanding of the dynamics underlying the fossil gasoline business is essential to fully comprehend market movements. As we anticipated in the beginning of this text, this is only the first part of a broader mission.
