For transportation and storage, natural gas is cooled and compressed into LNG. Contaminants in natural gas which need to be removed prior to liquefaction include total sulfur and BTEX.
Increasingly strict reporting regulations and tariffs on the sulfur content of sales quality natural gas has boosted the need for analysers with a fast response time and multi-component measurement capabilities. In addition, natural gas process producers often need to comply with contractual pipeline agreements and are interested in corrosion prevention on their liquefaction equipment.
Benzene, toluene and xylenes (BTEX) in pre-liquefied natural gas readily freezes at the cold temperatures required in the liquefaction process. The liquefaction equipment can become blocked or coated by these solids which requires shut down for maintenance. As a preemptive measure, LNG producers remove BTEX from the natural gas before liquefaction. Validation of the BTEX concentration in pre-liquefied natural gas ensures efficient BTEX removal to protect downstream equipment.
Applied Analytics offers an automated and continuous measurement solution for monitoring total sulfur and BTEX in pre-liquefied natural gas. Our equipment is designed with a focus on high accuracy, low maintenance and a fast response time. The OMA-300 is a complete solution for monitoring H2S, COS, MeSH, and EtSH to sum to a total sulfur measurement and determining BTEX concentrations in pre-liquefied natural gas.
