Leak detection in semiconductor fab gas processes

Problem Statement Often times in semiconductor fabs moisture levels are monitored to ensure that products aren’t damaged by excess moisture in the process. If there are above normal levels of moisture, pinpointing the source of that moisture can be difficult. The moisture could be evolving from impurities in gas tanks or leaks in the sampling lines. One way to avoid downtime ...

Early Ethylene Glycol Leak Detection in Power Plant Steam Condensate Is Essential

Fossil fuel and nuclear power plants use heat exchangers to condense process steam back into liquid form. A heat exchanger works by transferring heat from one medium (steam) to another medium (air, water, or ethylene glycol). Many newer, closed cooling water system, power plants use ethylene glycol use ethylene glycol (C2 H6 O2 ) as a heat transfer fluid because of its high-heat transfer ...

Mancomunidad de la Comarca de Pamplona (MCP) Identifies 4 Leaks Using Inline Leak Detection

Around the world, leaking water pipelines represent a major resource and financial loss for utilities. It is estimated that in some places, Non-Revenue Water exceeds 50 percent. In terms of financial losses, the World Bank estimates that NRW costs utilities worldwide about US$14 billion annually. By reducing these losses by half in areas with the highest NRW, it is estimated that US$2.9 billion ...

Carbon Dioxide (CO2) Leak in Soda Machines

Carbon dioxide, also known as CO2, is a very well known gas type but not everyone knows how deadly it is. Most people know it as a gas that humans exhale but commercially, it is manufactured and shipped as a liquefied compressed gas or is used as dry ice in its solid form. A common use of CO2 gas is in soda fountain machines to carbonate soft drinks by pressurizing the CO2 ...

Evaluating Leaks in a Soil Gas Sampling Train

ABSTRACT The current advisory for active soil gas investigations in California requires leak tests to be conducted at eveiy soil gas probe while taking a sample. A leak may allow ambient ak into the sample train thus diluting the soil gas and underestimating the results. Also, the leak check compound itself may have impurities thereby contaminating the sample. The advisoiy suggests leak ...
