Movement of air in industrial plants: weight mass and volume…

Sometimes it is necessary to determine airflow at different plant elevations before the cause of a problem can be determined. The following situation is an example of a problem that was solved by ascertaining airflow: The metal going through a press in a large press plant was turning a light brown and the customer would not approve the color change. The plant engineering department was notified of the problem. An engineer looked at the operation and without conducting any tests or studies concluded the problem was caused by the air that was being delivered in an area by a makeup-air unit. He thought that the air coming from the makeup-air unit was contaminated by the discharge from nearby boiler smoke stacks at the powerhouse. n his recommendation the air-supply unit was shut off. However the metal continued to change color.
Project house offers solution to skills shortage
Creamer Media's Mining Weekly – Feb 1, 2008
The construction verification and commissioning of the plant will be covered under a separate services agreement. The engineering and pro- curement of the plant have started with commissioning of the first of the two sulphuric acid plants scheduled for September 2009 with the second plant to follow about three months later. The full production of sulphuric acid will be used in the pressure-leach circuit processing nickel laterite from the mine site. In addition Du Rand says that Bateman has completed about 50% of the $59-million (about R401-million) platinum-group metals (PGM) concentrator for Blue Ridge Platinum. Bateman conducted the prefeasibility study and the full feasibility study for the plant which is targeting 125 000 oz of PGM a year. The contract includes the engineering design the procurement and management of all construction activities and the commissioning of the concentrator to a level at which the concentrator can receive ore… In addition Du Rand says that Bateman has completed about 50% of the $59-million (about R401-million) platinum-group metals (PGM) concentrator for Blue Ridge Platinum.

The contract includes the engineering design the procurement and management of all construction activities and the commissioning of the concentrator to a level at which the concentrator can receive ore. The plant which is scheduled for production in the fourth quarter of 2008 will treat upper-group-2-type material from underground which will make use of a flow sheet using a milling and flotation arrangement designed by Blue Ridge Platinum and Bateman. This design is typical for this type of ore. Bateman is also in the process of completing the $4076-million (about R27-billion) Lumwana copper project a joint venture between Bateman and Australian engineering and project management company Ausenco.
Thermal plant ‘would secure power supply’
New Zealand Herald – Feb 1, 2008
The New Zealand Energy Strategy and the Climate Change Bill flagged a decade-long moratorium on new thermal base-load power stations. However yesterday Genesis Energy spokesman Richard Gordon confirmed the company’s wish to take the proposal a big step further. Previously the company had wanted a base-load station which like its new EP3 gas turbine plant at Huntly ran continuously. But it had now redesigned operating and engineering plans to make it a cycling plant – one that ran only when extra capacity was required. Last August the Rodney District Council made a rare request to the Environment Minister to “call in” the application as a matter of national interest. It was concerned at estimates for carbon dioxide emissions from the station of 0.

Mendonca who leads the engineering tools team for Embraer’s first entries into the light and very light executive jet markets was instrumental in increasing the company’s use of manufacturing simulations and 3D-based process planning in early product development phases. Use of ‘manufacturing simulations since the early design phases’ he says ‘achiev[ed] significant reduction of assembly errors and expensive rework. This is then delivered automatically to a manufacturing execution system [MES] to manage actual production. PLM backbone solutions provide the integration and management of these tools and processes’ explained Ken Amann director of research at CIMdata Inc. a consulting firm specializing in PLM solutions.

(EDITRIAL FEATURE) The utility director at McCook NE reports the end of a 15-year-old nitrate contamination problem that increased in scope over the years to also include uranium and arsenic through the installation of a multi-contaminant-removal ion exchange treatment plant for the city’s drinking water. The new plant serving a 6. 8 mgd facility started up in early 2006 and provided simultaneous removal of all three contaminants. A 1998 Administrative rder from the Nebraska Department of Health & Human Services was lifted eight months after the treatment plant startup. “The long term upheaval is hopefully all behind us now” said Jesse Dutcher McCook utility director. “When a local regulator tells you that something needs to be fixed you don’t want to wait until it becomes a federal problem.

Background: The north coast area of outstanding natural beauty contains some of Northern Ireland’s premier bathing beaches. New infrastructure was required to improve the treatment of wastewater and bring effluent discharges into the sea up to EU water standards. Who is behind it? Northern Ireland Water and consultancy Scott Wilson which provided engineering architectural and landscape design services. Project aims: To modernise sewage and wastewater treatment facilities in an environmentally sensitive area and improve water cleanliness. Skills involved: Conservation partnership working landscape design and engineering.
