Today, we want to talk about the Phillips recovered furnace carbon black manufacturing process.

The manufacturing process of carbon black by Phillips Carbon Black Limited involves selecting high-quality raw materials, processing them into feedstock, subjecting the feedstock to controlled combustion in a furnace, separating the carbon black particles from the gas stream, pelletizing the particles, and conducting rigorous quality control checks. This process ensures the production of carbon black with consistent quality and properties, which are essential for its use in various industrial applications. PCBL's commitment to maintaining high manufacturing standards has established it as a trusted provider of carbon black in the market.

The manufacturing process of recovered carbon black involves the collection and preparation of end-of-life tires or rubber products, shredding and grinding the material, pyrolysis to break down the rubber and extract the carbon black, gas separation to capture valuable gases, carbon black recovery through purification techniques, and rigorous quality control measures. This process enables the recycling of waste rubber and the production of sustainable carbon black, contributing to the circular economy and reducing the environmental footprint associated with tire disposal. The use of recovered carbon black in various applications provides an environmentally friendly alternative to traditional carbon black production methods. The furnace carbon black manufacturing process involves the selection and processing of high-quality hydrocarbon feedstock, controlled combustion in a furnace to produce carbon black particles, quenching to solidify the particles, filtration, and separation to separate carbon black from the gas stream, pelletizing the carbon black aggregates, and implementing strict quality control measures. This process enables the production of carbon black with consistent properties, making it suitable for a wide range of applications in rubber, plastics, inks, and other industries. The efficiency and versatility of the furnace carbon black manufacturing process have established it as a key method for producing carbon black on a large scale.

Phillips carbon black manufacturing process

The first part of the article is about Phillips's carbon black manufacturing process.

Philips Carbon Black Limited (PCBL) is a leading manufacturer of carbon black, a crucial raw material used in the production of various rubber and plastic products. The manufacturing process of carbon black involves several key steps, from raw material selection to the final product. Here is a concise overview of the process:

Raw Material Selection: PCBL selects high-quality petroleum residue or coal tar as the primary raw material for carbon black production. These materials undergo rigorous testing to ensure their suitability for the manufacturing process.

Feedstock Processing: The selected raw materials are processed in feedstock units to remove impurities and convert them into a liquid state. The feedstock is then transported to the carbon black production units.

Carbon Black Production: PCBL employs the furnace process for carbon black production. In this process, the feedstock is injected into a furnace where it undergoes controlled combustion at high temperatures, typically around 2000 degrees Celsius. This combustion process results in the formation of carbon black particles.

Particle Separation: After the combustion process, the mixture of gases and carbon black particles is rapidly cooled, causing the carbon black to condense into solid particles. The solid particles are then separated from the gas stream using advanced filtration techniques.

Pelletizing and Packaging: The separated carbon black particles are subjected to pelletizing, where they are agglomerated into small pellets for easy handling and transportation. The pellets are then packaged and stored in appropriate containers to maintain their quality.

Quality Control: Throughout the manufacturing process, PCBL maintains stringent quality control measures. Samples are taken at various stages and tested for parameters such as particle size, structure, and surface area to ensure consistent quality and meet customer requirements.

Recovered carbon black manufacturing process

The manufacturing process of recovered carbon black (rCB) involves the recycling of end-of-life tires or rubber products to extract valuable carbon black. This sustainable process helps reduce waste and minimize environmental impact. Here is an overview of the rCB manufacturing process:

Collection and Preparation: End-of-life tires or rubber products are collected from various sources, such as tire recycling centers or waste management facilities. These materials undergo a thorough inspection and are sorted based on their composition and quality.

Shredding and Grinding: The collected tires or rubber products are shredded into smaller pieces to increase their surface area. The shredded material is then further processed through grinding equipment to reduce it into fine particles. This step facilitates the subsequent extraction of carbon black.

Pyrolysis: The ground rubber particles are subjected to pyrolysis, a thermal decomposition process conducted in the absence of oxygen. The rubber particles are heated at high temperatures, typically between 450 to 600 degrees Celsius, in a specialized reactor. This process causes the rubber to break down into its constituent components, including carbon black.

Gas Separation: During pyrolysis, gases and volatile compounds are released along with the carbon black. These gases are carefully separated and captured for further processing or energy recovery, depending on their composition and market demand.

Carbon Black Recovery: The remaining solid residue from pyrolysis contains the recovered carbon black. This residue is further processed to remove any remaining impurities and contaminants. Techniques such as magnetic separation, air classification, and filtration are employed to ensure the purity of the recovered carbon black.

Quality Control: Throughout the manufacturing process, quality control checks are conducted to ensure that the recovered carbon black meets the desired specifications. Parameters such as particle size, structure, and surface area are analyzed to verify the quality and consistency of the rCB.

Furnace carbon black manufacturing process

The furnace carbon black manufacturing process involves the combustion of hydrocarbon feedstock in a controlled environment to produce high-quality carbon black. This process is widely used in the industry due to its efficiency and versatility. Here is an overview of the furnace carbon black manufacturing process:

Feedstock Selection: High-quality hydrocarbon feedstock, such as natural gas, oil, or coal, is selected for the production of furnace carbon black. The choice of feedstock depends on factors like availability, cost, and desired properties of the carbon black.

Feedstock Processing: The selected feedstock undergoes processing to remove impurities and convert it into a suitable form for combustion. The processing steps may include purification, refining, and fractionation to ensure the feedstock's quality and consistency.

Combustion: The processed feedstock is injected into a furnace or reactor at high temperatures ranging from 1,300 to 1,800 degrees Celsius. The combustion process occurs in a controlled environment with limited oxygen supply, known as a reducing atmosphere. This controlled combustion leads to the formation of fine carbon particles.

Quenching: After the combustion process, the gas stream containing the carbon particles is rapidly cooled using water or another quenching medium. The sudden cooling causes the carbon particles to solidify and form aggregates.

Filtration and Separation: The solid carbon aggregates are separated from the gas stream using advanced filtration systems. Filters capture the carbon particles, while the remaining gases are directed to pollution control systems for further treatment.

Pelletizing and Packaging: The separated carbon black aggregates are processed into pellets through pelletizing equipment. The pellets are then dried, cooled, and packaged according to customer requirements.

Quality Control: Rigorous quality control measures are implemented throughout the manufacturing process to ensure the final product meets the desired specifications. Carbon black samples are regularly tested for parameters like particle size, structure, surface area, and impurity content.
