Introduction of Havayar Gas International Company
Havayar Gas International Company was established in 2019 with the aim of operating in the oil and gas industry. In 2020, the company participated in a flare gas auction and successfully acquired the flare gases of the Cheshmeh Khosh operational unit. Utilizing these gases, the company produces essential products such as natural gas, LPG, and pentane plus.
Flare gases, also known as flare stack gases, refer to excess gases that are obtained alongside oil extraction. These gases, especially in the past, were burned using flare stacks, causing significant environmental damage. Flare gases typically contain valuable components such as methane, ethane, and propane, and burning them equates to wasting precious natural resources. Havayar Gas International Company, leveraging modern technologies, utilizes these gases and, instead of burning them, transforms them into valuable products.
Analysis of LPG Gas Parameters by Havayar Gas International Company
Temperature and Pressure
This image indicates that the LPG gas analysis was conducted at a temperature of 33.4 degrees Celsius, where the liquefied gas has a pressure of 8 bar. These two parameters demonstrate that the equipment required for the storage, transfer, and transportation of this gas must be designed to withstand these conditions. In other words, the tanks must be capable of handling a pressure of 8 bar at a temperature of 33.4 degrees Celsius without any issues.
Mass Flow
Mass flow refers to the mass of a substance passing through a specific point per unit of time. Its unit is typically kilograms per hour (kg/h). Mass flow provides critical information about the amount of gas flow within a given system. This parameter is essential for the design and adjustment of equipment related to the transfer, storage, and utilization of gas. It helps accurately calculate the system’s capacity as well as the gas consumption or production rate.
Ethane (C2)
Ethane, as a highly volatile hydrocarbon, can create issues in the storage and transportation of LPG if present in amounts exceeding the standard limits. Due to its high vapor pressure, ethane may pose risks such as increased likelihood of leakage or unsafe conditions. Therefore, the ethane content in LPG should either be zero or, as observed in the LPG gas analysis of Havayar Gas International Company, maintained at a very low and controlled level.
However, the presence of very small amounts of ethane can also have certain advantages. Due to its high volatility and positive effect on vapor pressure, ethane can enhance the combustion process of LPG. This characteristic allows the fuel to burn faster and more efficiently, which can be particularly beneficial in applications requiring rapid and complete combustion.
Propane (C3) and Butane (C4)
Propane and butane are the two main components of liquefied petroleum gas (LPG). As observed in the analysis, the percentage of propane is approximately 45%, while the percentage of butane (the combined percentages of its two isomers, n-butane and isobutane) is about 53%. Given that the percentage of butane is higher than that of propane, the provided LPG is classified as “warm LPG,” which is suitable for warm and moderate climates.
Pentane (C5)
The presence of pentane in LPG analysis contributes, on the one hand, to increasing the heating value, thereby enhancing the usable energy. On the other hand, it can lower the vapor pressure, which may lead to issues in the combustion and burning process. The allowable amount of pentane varies depending on its application; in industrial needs, small amounts of pentane can be beneficial and improve process efficiency. However, for household and automotive use, due to the high sensitivity to vapor pressure and combustion quality, the pentane content should be zero or near zero to prevent functional problems.
