New approach makes faster and efficient work of oil spills

by DESMI A/S  (Sep. 29, 2014)

A comprehensive new study of oil’s behaviour in various sea conditions has resulted in significant advances in oil spill recovery using boom-style systems. Put into practice in DESMI ‘s Speed-Sweep Oil Spill Response (OSR) solution, the new approach speeds up oil recovery, increases encounter rates, covers a wider area in a shorter ...

Horizontal mixers for secondary combustibles case study

by AVA - Huep GmbH u. Co. KG  (Apr. 14, 2014)

The manufacture of secondary combustibles from household waste, industrial waste and special waste in accordance with statutory requirements is to be a huge challenge for system suppliers in the coming years. Currently, at times, extremely differing substances are treated in such a way that they can be loaded into conventional furnaces. The most ...

Effect of the number and length of zonal isolations on pressure behaviour of horizontal wells

by Inderscience Publishers  (Feb. 21, 2014)

Horizontal wells with multiple zonal isolations have become a common completion technique in the oil and gas industry. Sand problems, damaged zones, and water or gas coning are the main reasons for using isolators to sustain or improve oil and gas recovery. However, they have certain effects on pressure behaviour of horizontal wells. This paper ...

Storm Debris Recovery & Processing

by BioCycle Magazine  (Aug. 22, 2014)

Mobile wood grinding fleet, qualification as a preapproved cleanup contractor and reliable outlets for processed debris are keys to success. The weeklong winter storm that hit the south and East Coast last February was a record-setting event. The state of South Carolina lost 11 percent of its timber, with North Carolina and some East Coast ...

ANSI N13.1-2011 Stack Sampling Considerations

by HI-Q Environmental Products Company  (Sep. 20, 2014)

Background Nuclear facilities are required to follow industry standards for sampling stack effluents. Exposure of the general public to released radionuclides must be monitored as specified in US governmental regulations. The United States Environmental Protection Agency (USEPA) and the United States Nuclear Regulatory Commission (USNRC) have the ...

Start-up of first 100 kw system in Shanghai with 3-sun PV Mirror modules

by JX Crystals  (Aug. 28, 2014)

ABSTRACT Thanks to funding from the Shanghai City government, Shanghai Import Export Trading Company, and Shanghai Flower Port, we have designed and fabricated in pilot production the first 3-sun 180 W (STC) mirror panels. Three of these panels were first tested in the US showing calibrated PTC ratings of 150 W. Then 24 panels were installed on ...

Treatment of municipal wastewater using horizontal flow constructed wetlands in Egypt

by IWA Publishing  (Jan. 16, 2014)

The aim of this study was to evaluate the performance of two pilot horizontal flow constructed wetlands (HFCWs) with and without vegetation. Three types of plants namely Canna, Phragmites australis and Cyprus papyrus were used. The surface area of each plant was 654 m2. The flow rate was 20 m3 d−1 and the organic ...

Determination of horizontal in-situ stresses and natural fracture properties from wellbore deformation

by Inderscience Publishers  (Dec. 2, 2013)

Accurate and low-cost information on in-situ stresses and fracture properties is critical in reducing well costs and increasing well recoveries. In this paper, a hybrid model based on the displacement back analysis is proposed for determining the in-situ stress magnitudes and fracture properties at the wellbore scale using wellbore displacements. ...

Design, construction and performance of a horizontal subsurface flow wetland system in Australia

by IWA Publishing  (Nov. 13, 2013)

Malabugilmah is a remote Aboriginal community located in Clarence Valley, Northern NSW, Australia. In 2006, seven horizontal subsurface flow wetland clusters consisting of 3 m × 2 m wetland cells in series were designed and constructed to treat septic tank effluent to a secondary level (Total Suspended Solids (TSS) < 30 mg/L and ...
