What is the difference between condensate and light hydrocarbons, and what can they be used for?

1. Differences. 1. The characteristics are different.

Condensate: 1) Exists in the gas phase in the ground and is liquid when it returns to the surface.

2) The condensate on the ground is liquid oil, but in the formation it is a gas, which is called condensate. Condensate is a mixture of petroleum dissolved in natural gas at high temperature and pressure. Condensate gas reservoirs are located in rocks thousands of meters deep underground. The main products developed are condensate and natural gas.

Light hydrocarbons: gaseous fuels delivered to users through the pipeline network, in which the light hydrocarbon content from liquid to gas is not less than 13% (v%). The mixing ratio can also be adjusted according to the requirements of the gas parameters of the user's gas appliances.

2. The composition is different.

The main component of condensate is a mixture of C5 to C11+ hydrocarbons, and contains a small amount of hydrocarbons greater than C8 and impurities such as sulfur dioxide, thiophenes, mercaptans, thioethers and polysulfides, and its fraction is mostly 20 200.

Light hydrocarbons: pentane (carbon 5), hexane (carbon 6), heptane (carbon 7), propylene, butene, pentene, etc. Among them, propane (i.e., carbon 3, subdivision and ethane), butane (carbon 4, subdivision also isobutane, n-butane).

Second, the use. Condensate: mainly used for natural gas;

Light hydrocarbons: Diesel fuel that replaces secondary energy and natural gas and liquefied gas with higher utilization value can change and optimize China's energy structure, which not only has high economic and environmental benefits, but also has more far-reaching energy strategic significance.

The differences between condensate and light hydrocarbons are as follows:

1) Gas condensate refers to the liquid phase component condensed from the natural gas in the condensate field, also known as natural gasoline.

The main component of condensate is a mixture of C5 C8 hydrocarbons, and contains a small amount of hydrocarbons greater than C8 and impurities such as sulfur dioxide, thiophenes, mercaptans, thioethers and polysulfides, its fraction is more than 20 200, the specific gravity is less than, and the content of its heavy hydrocarbon and non-hydrocarbon components is lower than **, and the volatility is good.

Condensate can be used directly as fuel and is a high-quality raw material for the refining industry, usually with a naphtha yield of 60% 80%, diesel oil at 20% and 40%, and an API degree of more than 50.

Condensate can be divided into three types: paraffin-based, intermediate-based, and naphthenic.

2) Light hydrocarbons refer to the lighter part of a series of substances formed by mixing carbon and hydrogen in different proportions.

The main component of natural gas is C1, containing a small amount of C2, and the main components of liquefied petroleum gas are C3 and C4, which are gaseous at room temperature and pressure, called gaseous light hydrocarbons.

The hydrocarbon of C5-C16 is liquid at room temperature and pressure, so we call it liquid light hydrocarbon. The lightest parts of liquid light hydrocarbons are C5 and C6, and saturated C5 and C6 are the best raw materials for bubbling gas.

Condensate uses.

1) Used as a raw material for oil refining: condensate is blended with heavier ** to produce naphtha, which can provide raw materials for chemical plants. It can also be blended with intermediate base ** and victory oil and cabinda** to produce raw materials suitable for aromatic reforming, or blended with paraffin-based ** such as Nile oil to produce crackers suitable for ethylene.

2) Used as ethylene raw material: condensate as ethylene cracking raw material has the advantages of low cost and high yield. If the whole fraction condensate is not suitable for the cracking raw material, a certain light fraction can be cut as the cracking raw material, and the remaining component is a good diesel fraction.

3) Used as aromatization: After aromatization, condensate can produce chemical raw materials such as benzene, toluene, and xylene.

4) In addition, the condensate can also be converted into syngas or hydrogen by steam reforming. The condensate can also be processed to make light liquid fuels.

Uses of light hydrocarbons.

Light hydrocarbons can be made into combustion gas for heating, which is the main raw material of light hydrocarbon gas, commonly known as mixed air light hydrocarbon gas.

At present, the clean fuels we use are still natural gas, liquefied petroleum gas and diesel. Natural gas and liquefied petroleum gas are very valuable chemical raw materials, and the added value after deep processing is very high, because there is no good alternative energy, it can only be burned as ordinary fuel. In today's increasingly tight world with energy **, burning it as an ordinary fuel is a waste of limited resources.

After the mixed light hydrocarbons are successfully applied to the gas field, they can replace the diesel fuel of the secondary energy and the natural gas and liquefied gas with higher utilization value, which can change and optimize the energy structure of China, which not only has high economic and environmental benefits, but also has more far-reaching energy strategic significance.

Produced from different mines, condensate is a relatively recombinant component of oil droplets in a natural gas field, a small oil droplet in a gas. The oilfield light hydrocarbon is the lightest component in the world, and the lighter component in the oilfield needs to be transported by pressure tank.

To put it bluntly, it is mainly composed of carbon5 to carbon7. The specific density depends on the ratio of C5, C6, and C7, and the approximate density is.
