Introduction to Tabriz Petrochemical Company
Tabriz Petrochemical Company is the largest company in the northwest of the country, operating in the production of polymer and non-polymer products. Some of its most important products include polyethylene, polypropylene, and pentane. Tabriz Petrochemical consists of various production units, one of which is the pentane production unit, with light naphtha as its feedstock. According to the Tabriz Petrochemical website, the pentane produced by this company is mainly used as a blowing agent for polystyrene production. In this article, we will analyze the pentane produced by Tabriz Petrochemical Company.
Analysis of Pentane Parameters from Tabriz Petrochemical Company
C5
As observed in the pentane analysis report of Tabriz Petrochemical Company, the provided pentane has a high purity of over 99%, with normal pentane accounting for 74% and isopentane making up 25%. The high purity indicates that more complex purification processes have been applied to this product, meaning that impurities and other compounds (such as hexane, heptane, or other hydrocarbons) have been minimized as much as possible. Therefore, the pentane from Tabriz Petrochemical Company can be used in applications requiring high purity.
Benzene
Pentane is typically extracted from crude oil or gas condensates through distillation or separation processes. Even after these processes, some impurities, such as benzene, may still be present in the gas analysis. However, as observed in the analysis, its concentration is a maximum of 5 ppm, which is very low and indicates the high quality of the product. Benzene, due to its high toxicity, is harmful to both the environment and human health. Additionally, if the product is intended to be used as a solvent or blowing agent in foams, the presence of benzene can degrade the quality of the final product. Therefore, the benzene content must be kept to a minimum.
Sulfur
The sulfur content in pentane can arise from various sources, with two main causes being the natural sulfur compounds in the raw materials and insufficient purification processes. However, the total sulfur content in the analysis of pentane from Tabriz Petrochemical Company can be a maximum of 50 ppm, as excess sulfur can negatively impact the physical and chemical properties of the final product. Pentane from Tabriz Petrochemical is primarily used as a blowing agent in polystyrene foams, so the purity of pentane is crucial, and its sulfur content should not exceed the permissible limit.
