    Gas blending (natural gas / LNG for CCGT)

    davefitz, Have you got a reference to the Siemens Westinghouse paper please (I've tried the siemens website, but there are no tech papers listed after 2004). Thank you.

    Gas blending (natural gas / LNG for CCGT)

    Thanks RMW. The LNG has some higher h/c's. The main concern is that it is higher CV than the gas it will be displacing (therefore higher Wobbe Index) - to compensate for the higher CV, using the existing burners, the revaporised LNG needs to be preheated {to a much higher temperature than the...

    Gas blending (natural gas / LNG for CCGT)

    CCGT fired by natural gas. Natural gas will be supplemented, at some future date, with LNG (natural gas and LNG will be blended and fired after 'correction' of the blended gas properties). Does anyone know of any CCGT power station that has moved from natural gas to natural gas/LNG blend (or...

    Cut and fill cost estimating

    Hello, I'm a Process Engineer. Am looking at a potential process plant project on a Mediterrean Island. The proposed site is hilly & in a Seismic zone. Cut and fill of volcanic sedimentary rock is required (minimal soil). Have had a civils study to estimate cost of preparatory works - I want...

    Glycol dehydration plant salt problem

    Thanks MGlycol. The data you tabulate for NaCl agrees with the charts that I have from an article in oil and gas journal. Do you have a reference for your values.

    Glycol dehydration plant salt problem

    mb44 - am talking to vendors. Thanks jay165. One problem is that NaCl has inverse solubility with temperature (CaCl2 other way round). NaCl comes out in lean TEG during the hot part of the regen. CaCl2 comes out at cooler temps. Some references state that you can operate at 1% salt in TEG...

    Glycol dehydration plant salt problem

    Salt carryover is causing problems in a triethylene glycol (TEG) dehydration plant. I have graphs for NaCl and for CaCl2 solubility in TEG from the oil and gas journal. Does anyone know of any data for mixes of salts in TEG (or for that matter MEG), or of any general sources of data relating...
