Emerson Process Management announced recently the release of significant updates to  DL8000 Preset Controller, the launch of Roxar RMS 2012, the latest version of its reservoir modelling software, and the release of the latest solution for combustion flue gas analysis, the Rosemount Analytical Model 6888 in situ oxygen analyser.

New features on the DL8000 simplify and enhance its capability to perform the blending, measurement, control, and monitoring needed to provide highly productive and rapid operations for the most common loading configurations.

The DL8000 now features an expanded set of configuration commands that can be entered directly from the keypad. Operators can easily change Meter Factor, K Factor, perform a meter prove and read and change other process parameters.

The DL8000 now provides support for ethanol volume correction based on either the OIML-R22 (1973) or ABNT NBR 5992 standards. Configuring a unit for ethanol product measurement is simple, requiring only the selection of ethanol fluid type, the selection of the preferred standard volume correction and a user-entered mass percentage of ethanol for the ethanol/water mixture.

The product features a straight forward, fill-in-the-blanks approach to configuration and covers a wide variety of liquids including crude oil, refined products, special application products, lubricating oils and light hydrocarbons. It is packaged in a Class 1 Division 1 explosion-proof enclosure or a Class 1 Division 2 enclosure and carries approvals from the NTEP (National Test and Evaluation Programme) under the US National Council on Weights and Measures, and CSA/UL approval.

Roxar RMS 2012

The launch of Roxar RMS 2012 sees the continued expansion of Roxar RMS into the geophysics domain through a completely integrated reservoir modelling workflow which includes seismic interpretation, reservoir simulation, reservoir behaviour predictions, and uncertainty management.

“With average global oil and gas recovery rates at just 22 per cent, the smallest percentage improvements can have a huge impact on both future oil and gas production and the bottom line,” said Kjetil Fagervik, managing director of Emerson’s Roxar Software Solutions. “Accurate predictive reservoir models which can realistically represent the underlying seismic data and offer a seamless route from seismic to simulation are absolutely central to efforts to improve oil and gas recovery today. These are the underlying goals behind Roxar RMS 2012.”

The Rosemount analytical model 6888

The key new features of RMS 2012 include seismic inversion, seismic attributes, and field planning.

• RMS Seismic Inversion allows geoscientists to use seismic data to create a rock property model quickly and accurately through increased automation.

• RMS Seismic Attributes is a powerful new visualisation toolkit which enables modellers to extract maximum value from their seismic data through the creation of attributes that more clearly define reservoir structure and guide the user through the facies modelling process.

Key features include new importing tools for SEG-Y data sets and the fast and accurate visualisation of seismic data sets of any size through interactive opacity control and colour manipulation capabilities. The colour coded attributes are particularly useful for interpreting rock properties, structural features and hydrocarbon accumulations and can be used for guiding facies distributions and aiding the identification of faults and discontinuities. In this way, operators can derive more from their seismic data and better quantify rock and fluid properties in the reservoir.

• The RMS Field Planning functionality enables modellers to quickly and accurately create multiple, optimal well plans for their fields. Key features of RMS Field Planning include increased flexibility in importing and exporting multiple targets in Comma Separated Values (CSV) format files; a Target Generator which enables modellers to create multiple copies of a target input with horizontal or vertical distance; the automatic generation of planned trajectories through a new Well Assignment Table; and three new data objects which can be visualised or interactively edited in 2D or 3D.

Rosemount Model

The Rosemount Analytical Model 6888 in situ oxygen analyser provides accurate measurement of the oxygen remaining in the flue gases coming from combustion processes such as boilers, incinerators, kilns, process heaters, and industrial heating furnaces. By maintaining the ideal level of oxygen in the flue gases, optimal efficiency is achieved and the lowest levels of NOX, CO and CO2 are produced.

The in situ design of the Model 6888 places a zirconium oxide sensing element at the end of a probe which can be inserted directly into a flue gas stream. Probe lengths are available from 18 inches to 12 feet, and a slip mounting option provides the ability to mount a long probe at any insertion depth. Signal conditioning electronics reside in the head of each probe, eliminating the need for expensive signal cable.

The Xi electronics offer unique optional features never before possible in an oxygen analyser.

• Calibration Recommended Diagnostic – Since the calibration frequency of an oxygen analyser is highly application-dependent, the Xi electronics of the Model 6888 provide an on-line diagnostic that determines when calibration should be conducted.

• Continued Operation Thro- ugh Process Upsets – If process upsets cause flue gas  temperatures to exceed the normal sensing cell heater temperature (736 degrees C, 1,357 degrees F), the heater is turned off, the process is permitted to heat the sensing cell, and the electronics calculate the oxygen content of the flue gases on the fly. If process upsets cause a reducing condition (flue gas oxygen levels decline to zero), a stoichiometer feature provides an indication of the level of oxygen deficiency during this event.

• Plugged Diffuser Diagnostic – In applications where there is a heavy particulate loading in the flue gas stream, this feature notes the “return to process” time after calibration gas is turned off. As the time extends, the diagnostic will indicate the need for a diffuser replacement.

“As the needs and compliance demands for flue gas analysis become greater, we are making our Rosemount Analytical instruments more and more accurate and easy-to-use to meet our customers’ requirements. The model 6888 promises real savings in time and resources for users, as well as a way to achieve compliance with government regulations,” stated Dave Anderson, marketing director, Emerson Process Management, Rosemount Analytical.
