Improved low flow measurement with Vortex flowmeters

• Improved signal processing leads to optimum turndown: Starts measur ing 16% lower in Reynolds than any other vortex flowmeter in the market. Versions with integrated two-line size reduction measure 76% lower • Most linear vortex body with flat ac curacy down to Reynolds no 10,000 • PremiumCal guarantees excel lent measuring accuracy +/- 0.65% (liquids) / +/- 0.9% (gas) enabling highest availability of your LNG plant at low flow rates

Vortex flowmeters have become the workhorse in LNG plants for both liquid and gas applications. Vortex flowme ter from Endress+Hauser is an excellent choice because of its robustness against temperature shock and vibration, and its multivariable (P+T) options. Most vortex flowmeters lose signal at low flows and measure inaccurately below a Reynolds number of 20,000. We help to overcome these challenges and more.

Gas sweetening processes remove acid gases (H 2 S and CO 2 ) from sour gas to meet specifications. Measuring H 2 S and CO 2 concentrations in sour gas at the inlet and sweet gas at the outlet of amine treatments units is important for control and optimization of the treatment process, to ensure the quality and prevent potential dam age to plant equipment. TDLAS analyzers have been proven to be highly effective in these critical measurements. • Exceptionally fast response to H 2 S and CO 2 con centration changes, an important performance characteristic for control of amine treatment units • Patented Differential Spectroscopy technique measures H 2 S at low ppm levels • Low maintenance and operational costs, as no cylinders of carrier and combustion gases, or lead acetate tape are required to perform measurements • Non-contact laser measurement avoids fouling and corrosion for reliable long-term operation of your LNG plant On-line monitoring of H 2 S and CO 2 in gas sweetening

Composition measurement of liquefied natural gas (LNG)

Accurate measurement of the composition of liquefied natural gas is necessary for calculating the energy content (BTU value and Wobbe index) and monetary value of the fuel during production and at downstream custody transfer points. In baseload LNG plants composition measurement of liquefaction rundown to storage tanks facilitates process control to avoid off-spec product. Composition measure ment is essential to transactions in LNG import / export terminals, marine bunkering, and truck loading operations. The Kaiser Raman analyzer measures LNG composi tion directly in the cryogenic liquid, in real-time, without the need to vaporize a sample for analysis. Eliminating the vaporization step required for gas chromatography reduces analysis time from minutes to seconds, and sig nificantly improves measurement accuracy. • Pilot™ cryogenic probe enables direct measurement in the LNG stream without sample extraction and need for vaporization • Raman Analyzer Field Calibration Tool verifies trans mission intensity and calibration as described in GIIGNL custody transfer handbook
