The chemical compatibility of materials used to construct analytical systems for sampling, transfer, and analysis of oil and gas must be carefully considered to maximize reliability. Specifically, virtually all natural gas samples contain sulfur compounds which need to be precisely quantified for quality purposes. In most applications, sulfur compounds like hydrogen sulfide (H2S) must be quantified at the parts-per-million (ppm) and sometimes even parts-per-billion (ppb) level.
However, the stainless steel components that typically make up a gas sampler are prone to absorbing sulfur compounds onto the surface. Though this problem may seem negligible in gas samples with a high percentage of sulfur concentrations, it is impossible to accurately quantify sulfur and other active compounds at trace levels without first treating the stainless steel flow path.Read More
Our cars wouldn’t run very well if we didn’t fill them with gasoline, change the motor oil, or conduct routine maintenance and repairs. In the same way, your facility’s sampling equipment needs regular preventative maintenance.Read More
The answer currently is 154. The leading brand of sample coolers – Sentry – supplies more than 6,000 per year to customers around the globe.Read More
Sentry sampling solutions for refineries are ready to meet any application, anywhere, even in extreme conditions. The following customer case studies show solutions for two applications, one in a high temperature and one in a sub-zero temperature environment.Read More
In the petrochemical industry, representative samples of liquid petroleum gas and other high vapor pressure gases and liquids are needed for process monitoring, quality control and regulatory compliance. However, in this industry, process fluids and gases are volatile or could be harmful to the operator and the environment, or they could be dangerously altered through a chemical reaction when exposed to the atmosphere – so exposure must be avoided. Because each sample collected may pose a physical or health hazard, and operators may take hundreds of samples per year, samples must be taken safely and correctly using the appropriate equipment and containers.
Metal corrosion is inevitable, and has the potential to cause catastrophic pipeline and assets failure, damaging the environment and communities, injuring field operators, and causing costly downtime and waste in productivity.Read More
A lot has changed since the 1970s – except the ban on U.S. crude oil exports. This relic from more than four decades ago was the result of global shortages that led the federal government to guard U.S. fuel supplies by blocking exports. The dynamic today has changed, with U.S. crude oil production near record-setting highs, due to the ability to access vast deposits domestically and the continued development of advanced drilling and hydraulic fracturing technologies.Read More
The cost of cleaning up the oil spill that fouled beaches last month on the California coast has reached $62 million so far, the pipeline company, Texas-based Plains All American Pipeline, said this month. Costs are running at $3 million a day, and there is no firm timetable for cleanup completion, according to the company. The company is responsible for paying all cleanup costs after a pipeline break near Santa Barbara forced the closure of two state beaches and prompted a fishing ban in the area.Read More
Industrial sampling is the act of capturing representative product from a process stream for the purpose of analysis. It is essential that during sampling the products are not contaminated by handling and are a current representation of the stream from which they are captured.Read More
Your water heater goes out in your home, and you have a purchasing decision to make: To save costs now, do you buy the cheaper water heater that may not provide as much hot water as your home needs, and that you will need to replace in a few years – or do you go with the higher quality model that your plumber recommends, which fully will meet the needs of your home and perform for up to 20 years? You decision will depend on a few factors, such as how much you can spend now and how long you plan to be in the home.Read More
