Abstract

GAS HYDRATES ARE ICE-LIKE CRYSTALLINE STRUCTURES WHICH MAY FORM IN HIGH PRESSURES AND TEMPERATURES ABOVE WATER FREEZING POINT.HYDRATE FORMATION IN THE GAS TRANSMISSION PIPELINES MAY LEAD TO INTERRUPT IN GAS TRANSMISSION AND PIPELINE BLOCKAGE. SO THE HYDRATE FORMATION MUST BE INHIBITED AS THE BLOCKAGE REMOVAL IS COSTLY AND TIME CONSUMING OPERATION.CHEMICAL INHIBITORS ARE COMMONLY USED IN ORDER TO PREVENT THE HYDRATE FORMATION IN GAS PIPELINES. THESE INHIBITORS ARE DIVIDED INTO THERMODYNAMIC AND KINETIC INHIBITORS. THERMODYNAMIC HYDRATE INHIBITORS EFFECTS ON WATER CHEMICAL ACTIVITY AND CAUSES THE HYDRATES TO FORM AT HIGHER PRESSURE AND LOWER TEMPERATURES. KINETIC HYDRATE INHIBITORS WITH LOW CONCENTRATION PREVENTS THE NUCLEATION AND GROWTH OF CRYSTAL HYDRATE.IN THIS PAPER THE KINETIC OF HYDRATE FORMATION WITH KINETIC HYDRATE INHIBITORS AND WITHOUT THEM HAS BEEN DESCRIBED. THEN THE RATE PROFILE VERSUS TIME WHEN KINETIC HYDRATE INHIBITORS WERE INJECTED AND WEREN'T INJECTED HAS BEEN DRAWN BY USING OF EXPERIMENTAL DATA IN GAS PIPELINE AND THE MODEL OF KASHCHIEV.AT THE END THE INDUCTION TIME OF HYDRATE FORMATION WHEN KINETIC HYDRATE INHIBITORS WERE INJECTED AND WEREN'T INJECTED HAS BEEN CALCULATED BY USING THE MODEL OF KASHCHIEV AND FIROOZABADI.
