Improve the safety and efficiency of natural gas sweetening units

After natural gas is extracted from onshore and offshore sites, it must be transported and processed. Raw natural gas is processed for purification, separation and liquefaction. Gas is sweetened in an amine unit and then dried in a dehydration unit before it can be transported via pipeline, liquified for transport or used as feedstock in refineries or petrochemical plants. This article focuses on processing facilities and, in particular, how measurement technologies can be used to enhance real-time control and monitoring of amine units, leading to gains in throughput and stipulated gas quality while improving safety and increasing efficiency. Before measurement details are discussed, a revi
