One of the biggest problem in processing natural gas is the often occurring blockage in the pipelines caused due to uncontrolled gas hydrate formation in the pipelines. Several millions of dollars are being spent at the process site to dehydrate the blockage safely by using chemical inhibitors. We aim to establish database, which addresses the physical conditions that promotes natural gas to form gas hydrates in the pipelines. Moreover, we aim to design and test novel hydrate inhibitors that are suitable for Qatari natural gas and its processing facilities. From these perspectives we are aiming to provide more effective and sustainable reservoir utilization and processing of Qatari natural gas. In this work, we present the initial finding of a big project, which deals with the natural gas hydrate formation characteristics of Qatari type gas in both experimental (PVTx) and computational (molecular simulations) methods. We present the commissioning of the new fully automated gas hydrate autoclave and measurements of hydrate equilibrium curves including growth/dissociation conditions for multi-component systems for several gas mixtures with and without the presence of well known kinetic and thermodynamic hydrate inhibitors.
