Dealing with rejection: selecting the best nitrogen removal for your LNG plant

New natural gas liquefaction projects require efficient, low CAPEX nitrogen removal options. This article will describe the steps to select the best nitrogen removal option for an LNG plant.

New natural gas liquefaction projects require efficient, low CAPEX nitrogen removal options. Several practical options for nitrogen removal from LNG are described in this paper and each arrangement offers unique benefits. There is no single solution that can be applied universally as each project will have different requirements. Key project variables such as feed gas composition and the selected refrigerant compressor driver impact the suitability of each nitrogen rejection solution. It is critical to understand the benefits of different equipment arrangements to develop a robust and reliable project selection.
