Phase-Controlled Thyristor Sub-Synchronous Damper Converter for a Liquefied Natural Gas Plant

Controlled Variables Selection for Liquefied Natural Gas Plant

The primary operational objective of liquefied natural gas (LNG) plants with low production capacity is to maximize LNG production. A robust control structure is required to meet economic objective while ensuring safety of the plant. The selection of appropriate controlled variables (CVs) is critical for design of the control structure. In this paper, general process understanding and the conce...

Liquefied Natural Gas for Trucks and Buses

Liquefied natural gas (LNG) is being developed as a heavy vehicle fuel. The reason for developing LNG is to reduce our dependency on imported oil by eliminating technical and costs barriers associated with its usage. The U.S. Department of Energy (DOE) has a program, currently in its third year, to develop and advance costeffective technologies for operating and refueling natural gas–fueled hea...

Liquefied Natural Gas Developments Specialreport

A multi-tube, spirally-wound, cryogenic heat exchanger, the main heat exchanger (MHE) is the principal piece of heat-transfer equipment in mixed-refrigerant liquefaction cycles for producing liquefied natural gas (LNG). An MHE unit operation model called the spirally-wound tube-bundle module was developed as an integral component of the dynamic simulation capabilities for a process modeling pac...

Feasibility Study of Liquefied Natural Gas Project for the "South-Pars" Gas Field of Iran

Dividing-Wall Column for Fractionation of Natural Gas Liquids in Floating Liquefied Natural Gas Plants

The development of floating liquefied natural gas (FLNG) plants has resulted in a focus on reducing the weight and size of the topside processing facilities for these units. The conventional fractionation of natural gas liquids (NGL) in LNG plants implies a direct sequence of three or more conventional distillation columns requiring different levels of refrigeration. The results of a feasibilit...
