Abstract: 

WITH THE DEVELOPMENT OF THE NATURAL GAS INDUSTRY IN THE 20TH CENTURY, THE PRODUCTION, PROCESSING AND DISTRIBUTION OF NATURAL GAS UNDER HIGH-PRESSURE CONDITIONS WERE NECESSARY. UNDER THESE CONDITIONS, IT WAS FOUND THAT THE PRODUCTION AND TRANSMISSION PIPELINES WERE BECOMING BLOCKED WITH WHAT LOOKED LIKE TO BE ICE. HAMMER SCHMIDT (1934) DETERMINED THAT HYDRATES WERE THE CAUSE OF PLUGGED NATURAL GAS PIPELINES. GAS HYDRATES AND DIFFICULTIES RELATED TO THEIR FORMATION IN PRODUCTION AND TRANSMISSION PIPELINES AND EQUIPMENTS, ARE THE MAJOR CONCERNS OF THE OIL AND GAS INDUSTRY. THE MAIN OBJECTIVE OF THIS STUDY WAS TO PRESENT A NOVEL APPROACH TO ACCESS MORE ACCURATE HYDRATE FORMATION RATE PREDICTING MODELS BASED ON THE COMBINATION OF FLOW LOOP EXPERIMENTAL DATA WITH FUZZY LOGIC AND ADAPTIVE NEURAL-FUZZY INFERENCE SYSTEM. THEREFORE, MORE THAN 467 DATA OF C1, C3, I-C4 AND CO2 HYDRATE FORMATION RATE WAS USED. IT WAS FOUND THAT SUCH MODELS CAN BE USED AS POWERFUL TOOLS, WITH TOTAL ERRORS LESS THAN 8% FOR THE DEVELOPED MODELS, IN PREDICTING HYDRATE FORMATION RATE IN THESE CASES.
