Refinery Implements Best Practices in Crude Oil Sampling

Posted by John Powalisz on 1/4/17 10:30 AM

Within the oil and gas industry, hydrocarbon liquids such as crude oil, condensates, and oil and water mixtures must be sampled to yield representative samples for analysis. The resulting data is used for quality control, to determine product properties and composition, and for fiscal calculations, allocations and loss control.

In addition to complying with custody transfer standards such as API 8.2 and ASTM D 4177, the advantages of representative sampling include:

  •  Higher return on investment
  •  Better loss control
  •  Lower operating costs

How low-emission sampling panels protect Chinese pandas

Posted by John Powalisz on 2/16/16 10:00 AM

With its numerous mountain ranges and valleys, and the Yangtze River running through it, the Sichuan region of southwest China is the country’s fifth largest province in terms of land. It is an important region that needs to be protected because of its agriculture, wildlife and historical significance to the country. Referred to as “The Land of Abundance,” the province contains many of China’s natural wonders, wildlife preserves, archaeological sites, ancient engineering achievements, museums and historical buildings – all tourist attractions. It also is China's leading agricultural producer of rice, wheat, sugarcane and other crops, and the western plateau and mountainous regions are important environmental and forest regions, rich in bamboo, white wax and ingredients for traditional Chinese medicine.
