无水焦油是一种化工产品，它是在煤高温干馏过程中产生的一种复杂混合物，主要由多环芳香族化合物组成，包括环烷烃、烷烃及酚类等成分。
无水焦油是通过去除煤焦油中的水分后得到的，它是煤焦化企业的副产品，煤焦化装置采用干馏工艺将煤生产焦炭和半焦炭时获得。
无水焦油作为燃料使用：无水焦油具有较高的热值，可用作燃料或燃料添加剂。
在化工行业的应用：无水焦油是生产塑料、合成纤维、染料、橡胶、医药、耐高温材料等多种工业品的重要原料。
在建筑材料行业的应用：用于制造沥青混凝土、屋顶防水材料等。
在医药行业的应用：焦油可以用于制造某些化学制品和油漆，经过深度处理和精炼，还可以用于制造高质量的防水材料、隔热材料和环保塑料等。
无水焦油的制造过程主要包括焦油蒸馏和洗涤分解等步骤，通过这些步骤，可以从焦油中分离出多种化工产品。具体包括：
焦油蒸馏：将焦油中的不同组分通过蒸馏分离出来，得到不同沸点的馏分。
洗涤分解：用碱性溶液洗涤焦油，以去除其中的杂质和酚类化合物，提高焦油的质量。
Anhydrous tar is a chemical product, which is a complex mixture produced in the process of high-temperature dry distillation of coal, mainly composed of polycyclic aromatic compounds, including naphthenes, alkanes and phenols.
Anhydrous tar is obtained by removing the water in coal tar, which is a by-product of coal coking enterprises, and is obtained by the coal coking unit when the coal is produced from coke and semi-coke by a dry distillation process.
Anhydrous tar is used as a fuel: Anhydrous tar has a high calorific value and can be used as a fuel or fuel additive.
Application in chemical industry: anhydrous tar is an important raw material for the production of plastics, synthetic fibers, dyes, rubber, medicine, high-temperature resistant materials and other industrial products.
Application in the building materials industry: used in the manufacture of asphalt concrete, roof waterproofing materials, etc.
Applications in the pharmaceutical industry: Tar can be used in the manufacture of certain chemicals and paints, after advanced treatment and refining, it can also be used to make high-quality waterproofing materials, thermal insulation materials and environmentally friendly plastics.
The manufacturing process of anhydrous tar mainly includes steps such as tar distillation and washing decomposition, through which a variety of chemical products can be separated from tar. These include:
Tar distillation: The different components in the tar are separated by distillation to obtain fractions with different boiling points.
Washing and decomposition: Wash the tar with an alkaline solution to remove impurities and phenolic compounds in it and improve the quality of the tar.
The color is black and bright, and can be produced as per customer’s requirements. Daily output is 300 tons, with long-term stability.
