Molecular sieve technology is widely used for the simultaneous removal of water and mercaptans from both gas and liquid feed streams. However, a better understanding of the design principles and the operation of molecular sieve units is needed. For economic reasons, it is important not to overdesign the molecular sieve unit. At the same time, it is essential to ensure that the unit does not become the bottleneck of the gas processing plant at the sieve’s end-of-run condition.
Details of the design and operation of molecular sieve units used for natural gas dehydration are discussed here. The application of expert know-how and practical recommendations can provide an effective way to maximize molecular sieve lifetime and performance. Part 1 focuses on the design principles and practices of molecular sieve units.View more
