INVENTORY MEASUREMENT MODEL FOR LIQUEFIED PETROLEUM GAS OF PETROCHEMICAL COMPANIES IN THAILAND.

Abstract

This research is qualitative research. The purpose of this research is to study the work pattern for setting up operational procedures and developing a method for measuring petroleum gas levels of a petrochemical company in Thailand. It is research in the field of actual operations with the population with special reference to workers in gas warehouses in all 5 regions in the country. Interview forms validated by qualified experts and calculation forms were used as tools for data collection. The research results showed that: the measurement of the gas level started from measuring the depth of the gas water; measuring the temperature of gas water; measuring the temperature of the gas vapor; and measuring the gas pressure and gas molar mass. After that a calculation was done to find the true volume from the developed calculation model. Table constants in Table 54 was compared to find the Density at 15°C and Table Tank table to find the total gas volume, after which it was then calculated in the developed calculation which made the gas volume increase by 20% than the previous model.
