Honeywell optimises pipeline operations in China
September 2015
System Integration & Control Systems Design
Honeywell Process Solutions has announced that its technology will help improve operations for China’s long-distance Guangxi liquefied natural gas (LNG) high-pressure pipeline.
A key strategic project of Sinopec and Guangxi Zhuang Autonomous Region, the Guangxi LNG pipeline will play a critical role in optimising China’s energy structure and meeting the demand for natural gas in Guangxi. The project will use HPS gas measurement equipment and software to measure the flow and pressure in the pipeline.
“We are able to draw upon our experience in long-distance, natural gas high-pressure pipelines to provide expertise to this essential clean energy project,” said Aldous Wong, HPS vice president, China. “Pipelines have challenges that are very different from processing plants, since you have to manage an operation that is hundreds or sometimes thousands of miles long. Measurements such as flow and pressure must be accurate and immediately accessible to keep the pipeline operating at maximum efficiency.”
The pipeline should be completed later this year, and will have a capacity of 8 billion cubic metres of LNG per year, and a total length of more than 200 kilometres. This pipeline will be part of a network that transports natural gas and LNG from as far away as Kazakhstan to China. HPS technology is already being used on all three of the 1800 kilometre central Asia to China pipelines, as well as the 9000 kilometre west to east pipeline.
The integrated gas measurement technologies provided by Honeywell includes computer software and sensors that measure flow, temperature, pressure and other indicators that are critical to maintain optimum performance throughout the pipeline. These include:
• Ultrasonic flowmeters, which measure natural gas for custody transfer applications, which require high reliability, excellent metering certainty and repeatability.
• Flow computers, which can perform parallel calculations of compressibility according to all established methods, including GERG 88 S, AGA 8 and AGA NX 19.
• SmartLine temperature and pressure transmitters, which deliver value across the entire plant lifecycle. These transmitters reduce initial purchasing costs, provide flexibility for post start-up modifications, and reduce maintenance and inventory costs while providing high accuracy and stability.
