What Are Petrochemical Products: Introduction + Uses

Petrochemical products include a wide range of chemicals such as methane, methanol, ethylene, propylene, benzene, toluene, butadiene, and many others. And each serves as a raw material in various industries and is an essential part of modern life. But what exactly are petroleum-derived products? They are substances that are produced through the process of converting crude oil or natural gas into basic chemical products. Then, they are eventually transformed into goods such as plastics, synthetic fibres, paints, detergents, and fertilisers. In this article from the Iran ETrade blog, a specialised source for petroleum product announcements, we will define petrochemicals and explore their types and applications.

An Introduction to the Petrochemical Industry

Petrochemicals originate from crude oil, natural gas, or gas liquids. Therefore, they are one of the main pillars of Iran’s economy, serving numerous industrial and household applications. Various types of bitumen, solvents, petroleum coke, cosmetics and personal care products, olefins, Teflon, and chemical fertilisers are made of the petroleum-derived products.

The petrochemical industry, as one of the most important branches of the chemical sector, produces organic and inorganic compounds using oil and gas feedstocks. Therefore, the petrochemical products industry links energy resources with processing industries and plays a key role in driving economic growth.

Classifying Petrochemical Industries

Petrochemical industries are divided into five main sections: upstream units, basic units, intermediate units, final units, and downstream units, each playing a different role in the production process.

• Upstream Units: In these units, the linear hydrocarbons in oil and gas separate from other hydrocarbons and are then sent to the basic petrochemical units for further use.
• Basic Units: These units in chemical complexes convert raw materials into base chemicals such as ethylene and propylene and then send them to the intermediate units.
• Intermediate Units. In these units, workers prepare the feedstock needed for the final units.
• Final Units: These units are at the end of the production chain, where the final petroleum-derived products are manufactured.
• Downstream Units: These include processes that transform final products into consumer goods such as plastics, synthetic fibres, and more.

Feedstocks for Petrochemical Products

The main feedstocks for petrochemical industries include light and heavy naphtha, natural gas, liquefied gas, ethane, propane, and butane. Although, depending on the type of feedstock and the technology used, different products are produced.

Types of Petrochemical Products

Petrochemical products fall into three main categories based on their production stages. Therefore, we will explain basic, intermediate, and final petroleum-derived products in this section.

1. Basic Products

Basic petroleum-derived products are produced from naphtha, natural gas, or gas liquids. Olefins are one group of basic petrochemicals and include ethylene, propylene, and butadiene. The second group consists of aromatics, which are also basic petrochemicals and include substances such as benzene, toluene, and xylenes.

2. Intermediate Products

As their name suggests, intermediate products such as polyethylene , polystyrene, and vinyl chloride monomer are produced from basic products and are used in the manufacturing of final petroleum-derived products.

3. Final Products

Chemical fertilisers, detergents and personal care products, synthetic fibres such as nylon, industrial solvents, and rubber are some of the final petrochemical products that have uses in industries and our daily lives.

The Most Important Petrochemical Products

Butane, benzene, propylene, toluene, resins, medical plastics, automotive parts, food preservatives, and carpets and rugs are some of the petrochemicals.

Among hundreds of petrochemical products, some compounds have great importance due to their wide applications and significant role in the production chain. Below, we introduce the most important petrochemicals:

1. Methane
