Abstract: Embodiments provide a method for preventing shutdowns in LNG facilities by removing heavy hydrocarbons from the inlet gas supply. According to an embodiment, there is provided an LNG facility treating pipeline quality natural gas that is contaminated with lubrication oil and low concentrations of heavy hydrocarbons. Due to contamination, the behavior of the pipeline quality natural gas is not properly predicted by thermodynamic modeling. In an embodiment, heavy hydrocarbons are removed by a drain system in a heat exchanger. In an embodiment, heavy hydrocarbons are removed by a treatment bed.

Abstract: A computerized method for online trading of options is disclosed. The method includes the steps of providing an interface screen that shows market data and market data analysis useful to conduct a transaction and allows a user to input various transaction parameters, wherein the market data and market data analysis shown on the interface screen are continuously updated; dynamically receiving selected transaction parameters for an option from the user; calculating an option premium for the option based on the selected transaction parameters and the continuously updated market data; providing the dynamically calculated option premium to the user; receiving an on-line offer for purchasing the option from the user; and presenting the received offer to a seller of the option for acceptance or rejection.
