A LNG plant with MRC cycle would not work under the designed condition all the time. It is significant to know the performance of a fixed MRC plant working at changed working condition. The problem involves the problem of plant simulation, which is somewhat similar to but actually different with the process simulation which is used in the design of a LNG plant. A model of MRC plant simulation w...

the levonorgestrel-releasing intrauterine system We write to report a recent European survey of factors that motivate women to use or reject the levonorgestrel-releasing intrauterine system (LNG-IUS). The survey comprised focus group sessions to identify barriers that prevent women using the LNG-IUS and individual interviews with current users to identify their reasons for having chosen the LNG...

The international liquefied natural gas (LNG) trade is expanding rapidly. Projects are being proposed worldwide to meet the industry forecasted growth rate of 12 percent by the end of the decade. LNG train designs in the coming years appear to fall within three classes, having nominal capacities of approximately 3.5, 5.0, and 8.0 million tons per annum (MTPA). These designs may coexist in the c...

IUD) is thought to act immediately by inhibiting sperm and ovum viability or preventing implantation.2 The LNG-IUS has a different contraceptive mechanism of action that relies on hormonal effects on the endometrium, cervical mucus and uterotubal transport, and thus has a delayed onset.2,3 This is the rationale for advising additional contraception for 7 days if a LNG-IUS is inserted after Day ...

OBJECTIVE The purpose of this study was to investigate if the levonorgestrel-impregnated intrauterine device (LNG-IUS, Mirena(®) ) is safe and effective as therapy for low-risk and medium-risk endometrial hyperplasia compared with oral medroxyprogesterone (MPA). DESIGN A multicentre randomised trial. SETTING Norway. POPULATION In all, 170 women aged 30-70 years with low- or medium-risk en...

Compressor performance for liquefied natural gas (LNG) main refrigeration units is very important due to the direct link between compressor efficiency and LNG production for a fixed amount of power. Dresser-Rand recently designed a series of new stages for the LNG market that provided improved efficiency and a wider range of operation. Industry practice is to rig test new stages prior to applic...

Since the 2004 guidance report by Sandia National Laboratories [1], the use of computational fluid dynamics (CFD) models to simulate LNG vapor dispersion scenarios has been growing steadily, with applications to LNG spills on land as well as on water. Before a CFD model may be applied to predict the vapor dispersion hazard distances for a hypothetical LNG spill scenario, it is necessary for the...
