We will present progress on work to add cloud condensate control variable to a 4D-VAR analysis system at ECMWF. First, in 4D-VAR the linear physics scheme needs prognostic cloud variables to be able to use additional cloud information from observations, and in the current phase of our development the additional prognostic variable is cloud condensate (cloud liquid water and ice). Second, it is ...

Condensate of black liquor vapors is known to cause corrosion in pulp mill equipment like digesters, flash tanks, storage tanks, evaporator domes, and other equipment handling black liquor condensate. This type of corrosion typically occurs in parts of equipment where the black liquor vapors can condense on a metal surface. Generally organic acids and other wood extractives in the condensate ar...

During plant operation, corrosion products from feedwater, drain and condensate system accumulate on the secondary side of steam generator in form scaled deposits around tubes sludge piles top tubesheet. These increase potential for corrosion, affect fluid flow reduce heat transfer efficiency generator. Using data obtained during periodical eddy current examination tubing, information deposit l...

With the increase in thermal power capacity, ultra supercritical units have become the mainstream of power industry. At the same time, with the improvement of the steam parameters and the lengthening of shafting, the production of steam flow excited vibration is frequent in the ultra supercritical units, which may seriously affect the reliability of the unit. This paper has taken steam flow exc...

The economic feasibility of resource recovery projects depends largely on the amount of revenue that can be obtained from the recovered energy products. The revenue that can be obtained from steam is dependent on the type of steam market available. The type of steam market in turn affects the design of the resource recovery facility and its capital cost. This paper discusses how the proposed st...

Background: The shortage of skilled workers choosing STEM (Science, Technology, Engineering, and Math) careers in the USA and worldwide has fueled a movement towards STEAM, in which the “A” addresses the arts and humanities. STEAM education has been proposed as a way to offer relevant problems to solve while drawing on creative and collaborative skills to increase interest and engagement in the...

A composition stream from reservoir to the market has been obtained as a result of upstream, midstream and downstream retrograde gas-condensate models integration. Applications are composition, Peng-Robinson EOS has been chosen as a fluid package. Different production scenarios were observed to define development strategy for rich gas condensate production. VGD and C/V gas drive mechanisms have...

The Extreme Measurement Communications Center at Oak Ridge National Laboratory (ORNL) explores the deployment of a wireless sensor system with a real-time measurement-based energy efficiency optimization framework in the ORNL campus. With particular focus on the 12-mile long steam distribution network in our campus, we propose an integrated system-level approach to optimize the energy delivery ...

the genus boswellia is one of the 17 genera belonging to burseraceae family. in this study resin of boswellia carteri birdwoodcollected or purchased from tehram herbal market as a food and non-food for chemical analysis. the essential oils of the resins of boswellia carteri birdwoodobtained by different methods of distillation (water distillation, steam distillation and hydro-steam distillation...

A Bose-Einstein condensate can be well described by an order parameter called condensate wavefunction. If Bose-Einstein condensation occurs in a superposed single particle state, the condensate wavefunction is correspondingly superposed. Likewise, if two coupled distinguishable or non-overlapping Bose systems condense in an entangled single particle pair state, the condensate wavefunction is co...
