Marine Fuel Management

Marine fuel costs represent a major portion (60–70%) of a ship’s operating cost. With increasing oil prices and conservation efforts, careful fuel management and increased engine efficiency have become vital for environmental and financial reasons. Fuel flow measurement with Coriolis technology provides the foundation for increased fuel efficiency and accurate accounting of fuel purchases. Even a medium-sized 30,000 DWT vessel can consume 20 tons of fuel oil per day, which at today’s prices is greater than USD6,000 per day.  This white paper describes how Micro Motion Coriolis meters can decrease the cost and waste associated with the fuel supply chain, from on-shore blending and barge loading to ship bunkering and fuel efficiency optimization.

Diversified Technologies for Fixed Gas Detection

(White Paper by General Monitors): In order to mitigate the potential spread of hazardous events, General Monitors is recommending the use of technology diversification. The term “diversification” is commonly used in the fire, gas, and safety industry to describe the principle behind protection layers; whereby safety layers that don’t share common failures are designed to reduce the probability and severity of hazardous events2.

An effective approach for technology diversity is to use the human sensory model. Like a person who is able to assess danger through his senses, fire and gas systems that rely on a combination of ultrasonic, optical, and conventional detection can provide a better picture of overall plant safety.

Improving Profits in Natural Gas Measurement by Using Coriolis Check Meters

Coriolis flow measurement technology is roughly 25 years old. However, until the early 1990s, the technology was generally viewed as “not working” on gas  applications.

Micro Motion introduced Coriolis meter designs in the early 1990s that solved the technical hurdles of gas measurement, but there was still a widespread belief that Coriolis meters were unfit for gas applications.To help combat these perceptions about Coriolis meters, Micro Motion conducted a wide range of tests at Southwest Research Institute (SwRI) in Texas, Colorado, Engineering Experimental Station (CEESI) in Colorado, Pigsar/Ruhrgas in Germany, and Gasunie in the Netherlands to prove Coriolis' suitability for gas measurement. The tests demonstrated not only that Coriolis meters perform extremely well in gas applications, but that Coriolis meters can be calibrated on water and that calibration is transferable to gas applications.

Integrating Gas Chromatographs with Control and Device Management

(Emerson Experts Blogs) Gas Chromatographs (GCs) are used in many process-manufacturing processes. Some GC applications include fuel & flare gas analysis, cracking furnace BTU firing rates, gas ratios, and a whole lot more.

I share this for those not already well steeped in the knowledge of GCs as background for an article by Emerson’s Jonas Berge and Michael Gaura in Gas Today Australia. The article, GC made easy: integrating process gas chromatographs, describes how digital communications technologies and standards such as Foundation fieldbus (FF) and Electronic Device Description Language (EDDL) have made the information collected by GCs more readily accessible to improve the process and easier to maintain to provide continued accuracy over time.
