Introduction to Khark Petrochemical Company
Kharg Petrochemical Company is one of the leading companies in Iran’s petrochemical industry, established in 1967 with the collaboration of foreign companies. The primary purpose of establishing this complex was to prevent the wastage of sour gases resulting from crude oil extraction. These gases, which were previously flared and wasted, are now processed at Kharg Petrochemical Complex into valuable products, playing a significant role in the country’s economic development.
Kharg Petrochemical is one of the largest methanol producers in the country and also produces butane, propane, sulfur, and naphtha. In this article, we will analyze the LPG gas produced by Kharg Petrochemical.
Parameter Analysis
Specific Gravity
The ratio of the density of LPG gas to the density of air is represented by the symbol SG. To evaluate this ratio, the density of LPG gas and air must be measured under the same temperature and pressure conditions. If this ratio is higher than one, it means that the liquefied gas is heavier and accumulates at the bottom, posing a greater risk. However, if this ratio is less than one, the liquefied gas has a lower density and, in case of leakage, moves upward. Therefore, the SG ratio should be less than one so that the provided LPG gas has greater safety.
Copper Corrosion
Copper corrosion refers to the degradation of copper. To determine the extent of corrosion, a polished copper strip is exposed to LPG for a specified period. After this period, the copper strip is examined for signs of corrosion. This test provides valuable information about the presence of impurities, particularly sulfur compounds and other corrosive substances in LPG. It is crucial because corrosive compounds can damage equipment and impose significant costs.
Vapour Pressure
Another important parameter in the analysis of LPG from Kharg Petrochemical is its vapour pressure. To determine the vapour pressure level, the measurement is conducted at a specific temperature, which in this analysis has been set at 100°F. The higher the vapour pressure of LPG at a given temperature, the more hazardous it is, necessitating the use of tanks and containers capable of withstanding such pressure.
Total Sulphur
This parameter represents the total sulphur content, measured in ppm. A high sulphur content indicates lower LPG quality, which can lead to serious issues in fuel transmission systems and equipment, as sulphur is a known corrosive substance that increases the risk of corrosion. Additionally, when sulphur burns, it produces sulphur dioxide gas, which contributes to acid rain formation.
Non-Volatile Residue
This parameter determines the amount of non-volatile compounds. Non-volatile compounds refer to substances with high boiling points that do not convert into gas under normal temperature and pressure conditions. A high level of non-volatile compounds indicates lower LPG quality. The accumulation of these compounds can lead to blockages in equipment such as regulators. Therefore, controlling and reducing the amount of non-volatile compounds in LPG is essential to maintaining quality, safety, and optimal equipment performance.
