Abstract: Implementations described and claimed herein provide systems and methods for processing liquefied natural gas (LNG). In one implementation, a dry feed gas is received. The dry feed gas is chilled with clean vapor from a heavies removal column to form a chilled feed gas. The chilled feed gas is partially condensed into a vapor phase and a liquid phase. The liquid phase retains freezing components. The freezing components are extracted using a reflux stream in the heavies removal column. The freezing components are removed as a condensate. The vapor phase is compressed into a clean feed gas. The clean feed gas is free of the freezing components for downstream liquefaction.

Abstract: The present disclosure discloses an organic silicon nano-precursor medium transmission inhibitor and its preparation method and use. The organic silicon nano-precursor medium transmission inhibitor is composed of an organic silicon and its derivatives, a catalyst, a dispersant, a stabilizer, a surfactant, and water. The organic silicon nano-precursor medium transmission inhibitor in-situ generates nanoparticles during a hydration process. The nanoparticles not only have a hydrophobic function, but also can effectively fill the pores of the concrete, which effectively solves a problem in which a hydrophobic material in a state of full water cannot reduce the diffusion of an erosive medium. The problems such as uneven dispersion and poor stability of nanoparticles added can be effectively solved by in-situ generating the nanoparticles, thereby effectively improving the ion corrosion resistance performance of the concrete.

Abstract: Systems and methods for processing liquefied natural gas (LNG) can include an LNG production system with a methane refrigeration cycle downstream from an ethylene refrigeration cycle. The methane refrigeration cycle can be a closed loop methane refrigeration cycle that maintains a methane refrigerant separate from a natural gas feed, (e.g., compared to an open loop methane refrigeration cycle that extracts the methane refrigerant from the natural gas feed and recombines the methane refrigerant with the natural gas feed). The natural gas feed can be a medium or high nitrogen gas feed having a nitrogen content greater than 1.0% molarity.
