    (Department of Electronic and Electrical Engineering, Faculty of Technology, Obafemi Awolowo University., 2022) AJAYI, Oluwasola Matthew
    This study examined the technological assessment of Liquefied Petroleum Gas retail industry in Osun state. The objectives are to identify the LPG nozzle dispensing technology among owners, the extent and level of adoption and critical technological issues in the LPG retail industry. These were with the view of ensuring policy and standard management practice on strategies for the running of successful LPG retail industry. The study was conducted in Ile-Ife, Ilesa, Ede and Osogbo which are located in Osun state, south western Nigeria. Data were collected using both primary and secondary sources. The primary source of data included structured questionnaire and interviews. The questionnaire was administered to the owners of 40 LPG retail industry purposively selected from each town, making the total of 160 respondents. The questionnaire was used to elicit information on the identification of nozzle dispensing technology and the extent and level of adoption of these technologies. Information was also obtained on the critical technology issues influencing these technologies. Secondary data which provided information on the various LPG retail industry operations globally in the past years and these were sourced from internet. The data generated from the study were analyzed using appropriate description and inferential statistic. The result of identification of nozzles dispensing technology showed on the frequency table, that high to low cylinder venting dispenser technology has the highest percentage of 57.30% which were the most popularly used within the studied area while one/more nozzle compressor dispenser has 29.3%, Locally fabricated compressor dispenser has 9.3% and single/double automatic dispenser has 4.0%. On the extent and level of adoption of these technologies showed that the result on the frequency table where only high percentage in each town was indicated; the industry that used more than one technology has 48.7% in Ede, the variation in the refiling duration of the technology was 75.0% often observed in Ile Ife. This was because of the difference measurements of Propane cylinders which were xvi to be used abroad are now being used in Nigeria. Health, Safety and Environmental training and maintenance of staff competence of 30.0% were observed in Osogbo, appropriate distance requirement of 100m x 100m of 37.5% and availability of safety equipment of 37.5% were also indicated in Osogbo respectively, operational technology above 10 years in Ile Ife has 32.5%, separation from the surrounding buildings in Ede has 87.5% and the occurrence of fire incident in Osogbo has 10.3%. On the critical technological issues; high to low cylinder venting dispenser has 73.8% which was the highest size of nozzle’s mouth, the system malfunction indicated 68.3% and the high risk of fire incident was 47.6%, air in the refiling hose has 38.9%, bad values has 43.6 % this was commonly observed in some areas and the locally fabricated dispenser showed 100% of no return mechanism in all studied area. The study concluded that the most LPG retail prefer single/double automatic nozzle dispensing technology, if safety procedures and right policies are enforced
