Development of High Performance Gas Treatment Processes and Equipment for Offshore Processing and Transportation of Natural gas
Compressed natural gas (CNG) has attractive features over liquefied natural gas (LNG) due to its easy and inexpensive transportation and delivery to the consumers. CNG is widely used to fuel transit buses, trucks, cars, and ocean going ships. Pipeline quality gas is usually used to bring the gas into compressed state. In pipeline quality gas, the contaminants including water and acid gases are removed and the gas dew point is readjusted in order to avoid hydrocarbon condensation during transportation. The evolving marine CNG technology mainly involves the transportation of gas from remote offshore production facilities, where the gas is not sufficiently treated and therefore, may contain varied amounts of acid gases, water and condensable hydrocarbons, which may pose operational problems in safe compression, loading, transportation, and unloading of natural gas. Major challenges associated with the existing technologies include the prediction of the retrograde condensation of rich associated gases during unloading operations and inhibition procedures, increasing the gas storage capacities and development of gas treatment equipment and processes. In order to achieve the targets, the project comprises the following phases: a) knowledge of industry needs, b) delivery of technical, analytical and scientific R & D services, c) dynamic simulation of different CNG storage potentials and d) developing gas treating/conditioning facilities.
