Product Introduction
Benzene is an aromatic hydrocarbon compound with the chemical formula C₆H₆. It is a core basic raw material in the petrochemical industry, derived from crude oil catalytic reforming, cracking and other processes. It has unique aromaticity and chemical activity, and is widely used in aromatic synthesis, medicine, pesticides, dyes and other fields. This article briefly introduces its types and characteristics, basic principles and system composition, core equipment and technologies, and operation processes, with Chinese-English comparison throughout.
Types and Characteristics of Equipment
Type
Benzene is classified by source, purity and substituent type, each with distinct characteristics and clear core commonalities, as follows: Petroleum Benzene: Derived from crude oil catalytic reforming and ethylene cracking by-products, with high purity (≥99.9%) and large output, it is the mainstream industrial type, used for large-scale aromatic synthesis. Coking Benzene: Derived from coal coking by-products, with low purity (95%-98%) and many impurities, it needs to be refined before use, mostly used in low-end chemical fields. High-Purity Benzene: Purity ≥99.95%, extremely low impurity content, used in high-end fields such as pharmaceutical intermediates and electronic chemicals. Industrial Benzene: Purity 99.5%-99.9%, meeting the needs of ordinary chemical production, used in dyes, pesticides, solvents, etc.
Features
At room temperature, it is a colorless transparent liquid with a special aromatic odor, insoluble in water but soluble in organic solvents such as ethanol and ether; flammable and volatile, toxic (long-term contact is harmful to human health); chemically stable, easy to undergo substitution reactions, difficult to undergo addition reactions.

Basic Principles and System Composition
Basic Working Principle
Production Principle: The mainstream is crude oil catalytic reforming method, using naphtha as raw material, generating benzene through dehydrogenation and cyclization reactions under the action of catalysts; the secondary is ethylene cracking by-product recovery method, separating and purifying benzene from cracked gasoline. Application Principle: Using its aromaticity and chemical activity, it is used as a raw material for synthesizing aromatics such as toluene and xylene, or as a solvent to dissolve organic substances, and can prepare various chemical products through substitution reactions.
Overall System Composition
Composed of four units: production, storage, transportation and application, working together to ensure stable production, safe storage and transportation, and efficient application. Production Unit: Including raw material pretreatment, catalytic reforming device, rectification separation device; Storage Unit: Special sealed storage tanks for separate storage; Transportation Unit: Explosion-proof and corrosion-resistant pumps, special pipelines to prevent leakage; Application Unit: Reaction kettles, blending devices, with supporting tail gas treatment.
Basic Principles and System Composition
Follow the standardized process of "Raw Material Pretreatment → Production and Processing → Storage → Transportation → Application → Safe Disposal", as follows: Raw Material Pretreatment: Dehydrate and remove impurities from naphtha (or cracked gasoline), send to production device after passing inspection. Production and Processing: After catalytic reforming (or separation and purification) and rectification, qualified benzene products are obtained, which are sent to the storage unit after passing inspection. Storage Operation: Store in a special corrosion-resistant sealed storage tank, control temperature, do a good job in explosion-proof, anti-static and anti-toxic measures, and store separately. Transportation Operation: Transport with explosion-proof and corrosion-resistant pumps and special pipelines, control flow and pressure, and strictly prevent leakage. Application Operation: Put into reaction or blending according to process requirements, turn on ventilation and tail gas treatment devices, and do a good job in protection during operation. Safe Disposal: Recover residual/waste benzene, standardize treatment of leaks, and do a good job in equipment maintenance and site ventilation.
