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...

New High Efficiency R-134a Compressor
Over the last thirty years, few changes have taken place in reciprocating refrigeration and freezer hermetic· compressors. Of course there have been design improvements and many new applications, but the basics have stayed the same. DOE requirements have brought new energy standards for 1993 and, with most of that work behind them, manufacturers of white goods are concentrating on alternate ref...
متن کاملLiquefied 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...
