摘要:
Natural gas liquefaction system employing a turboexpander to convert excess pressure within a predominantly methane stream into work useable in another location within the liquefaction system. Primarily, the turboexpander is used to compress a refrigerant used in at least one of the refrigeration cycles within the liquefaction system.
摘要:
A process and apparatus for the liquefaction of natural gas including an improved heavy hydrocarbon removal column with overhead condensing and refluxing. Particularly, a methane-rich stream exiting a propane refrigerant cycle is delivered to a heavies removal column, and the heavies depleted vapor from the column is at least partially condensed and the liquid portion provided as reflux to the heavies removal column.
摘要:
Natural gas liquefaction system employing an enhanced nitrogen removal system capable of removing nitrogen from a relatively warm natural gas stream.
摘要:
Natural gas liquefaction system employing an open methane cycle wherein the liquefied natural gas is flashed immediately upstream of the liquefied natural gas storage tank and boil off vapors from the tank are returned to the open methane cycle.
摘要:
Process for efficiently operating a natural gas liquefaction system with integrated heavies removal/natural gas liquids recovery to produce liquefied natural gas (LNG) and/or natural gas liquids (NGL) products.
摘要:
Methods and systems are provided for treating hydrogen sulfide rich sour gas through a series of fractionation columns. The processes disclosed herein and the variations thereof provide optimized processes for the removal of hydrogen sulfide from sour gas through the introduction of innovative azeotrope breakers, novel configurations of process equipment, and optimized operating conditions. Advantages of certain embodiments of the present invention include reduced equipment requirements, improved process efficiencies, reduced operating costs, and reduced capital costs. Other advantages include better process suitability to certain environmental conditions such as the arctic cold when compared to conventional amine treatment processes.
