Avoid heat input into the gas vessel with a diaphragm metering pump

Products Fig Prolimix

Before biomethane can be supplied to private and industrial customers, its calorific value must first be adapted to the natural gas network. The Prolimix mixer system from Scharr Tec GmbH & Co. KG can inject propane through several nozzles in liquid form and without energy-intensive evaporation.

Scharr Tec developed a concept that has now been successfully implemented in the industry for several years. Ecoflow diaphragm metering pumps from LEWA GmbH are mounted as a remote solution. These custom-made products from the Leonberg pump experts make it possible to avoid the problem of heat input, despite the increase in pressure caused by a driving head installed in the manhole shaft.

At the same time, the pump is precisely matched to the required flowrate, so that there is neither backflow into the tank nor any power loss. Since the pump is designed for 40-bar operating pressure, biomethane conditioning can also be carried out for long-distance networks.

Portable dewpoint analyzer for natural gas quality

Products Fig Mitchell

Michell Instruments’ CDP301 hydrocarbon and water dewpoint tester is a fully portable, manual-visual dewpoint instrument that uses the chilled mirror technique for accurate measurements of both hydrocarbon and water dewpoint. It is ATEX, IECEx and cQPSus compliant for use in a Zone 1 or 2 Hazardous Area and Class I, Division 1 Hazardous Locations, allowing it to be positioned close to the process sample test point. Since it is fully self-contained, there is no need to use a separate coolant gas.

The CDP301 includes a full-color interface that shows a magnified view of the mirror surface. Red-spectrum laser light illuminates fine water droplets and ice crystals when targeting water dewpoint. Broader-spectrum white light enables the iridescent film synonymous with hydrocarbon condensate to be detected with a high sensitivity of up to 5 mg/Nm3.

The temperature, pressure and dewpoint can be recorded at the push of a button. The video footage and/or still images, along with corresponding data, for multiple measurement cycles is logged for later review either on the instrument’s display or on a PC. The dewpoint tester also meets ASTM D1142 and ISO6327 requirements. GP

FEATURED COLUMNS

Editorial Comment
-Adrienne Blume
The IEA’s “Global Gas Security Review2020” report, released in October, projects that global gas demand will fall by 3%, or 120 Bm3, in 2020—the largest drop on record.
Industry Focus: COVID-19 stokes competition for Europe’s LNG market
-Eugene Gerden
The level of competition in the global LNG market is rising as major producers look to increase their shares in a market severely weakened by the COVID-19 pandemic.
Regional Focus: Mega-project in the FSU: Ongoing development of the Shah Deniz gas field
-Gordon Feller
Multiple billions of dollars have been invested to develop the Shah Deniz gas field.
Safety and Sustainability: A new standard of safety for onshore passive fire protection
-Richard Holliday
The onshore energy and petrochemicals sector is defined by the strength of its safety culture, but it has only recently begun moving toward adoption of the highest fire protection standards.


GasPro 2.0: A Webcast Symposium

View On-Demand

Following the successful GasPro Webcast Symposium in October 2019, the third GasPro Webcast Symposium will take place on October 21, 2020.

The 2019 webcast drew attendees from around the world, with more than 80% of the audience working in company management or engineering divisions.

The 2020 web event will gather experts in the fields of LNG, gas processing and process safety to share market, operations and engineering technology and trends with our audience.

Attendees of the 2020 webcast will learn about market solutions and technology deployments in a number of areas: LNG delivery infrastructure, small-scale desulfurization for NGL, H2S removal for gas treating, process safety for safety instrumented systems, small-scale LNG project design, and advances in freeze component removal for LNG.
