Portable / Field Testing On-Site Oil In Water Measurements using Portable IR Analysers
Oil in water discharges are highly regulated and each region of the world has their specific regulations. For the offshore oil industry, regulating bodies such as the NPDES (National Pollutant Discharge Elimination System) in the US have strict part per million (ppm) limits that are coupled with costly fines for non- compliance. On-shore industrial wastewater producers also have limits imposed either by the wastewater treatment facilities or by government regulations such as the US Clean Water Act (CWA) or the EUs Integrated Pollution Prevention and Control (IPPC). Excessive amounts of oil in the wastewater discharge can lead to fines and/or pollution from sanitary sewer overflows (SSOs).
Portable infrared analysers, such as the InfraCal TOG/TPH Analysers fromWilks Enterprise (USA), provide on-site oil in water measurement capability in a matter of minutes, eliminating the wait for off-site laboratory results. They help provide the assurance that oil in water levels are in compliance with discharge permits and give treatment operators needed information on how their system is performing.
The rugged InfraCal TOG/TPH Analysers have been specifically designed for easy, on-site measurement of oil and grease concentration levels in water in under 15 minutes and are built for years of dependable operation. They are based on field-proven infrared technology and enable non-technical users to obtain accurate measurements with a few simple steps. Measurement data correlates with EPA Methods 1664, 413.2, 418.1 and ASTM Methods D7066 and D3921. Currently, there are nearly 3,000 InfraCal Analysers in worldwide operation – many of which are on oil and gas drilling platforms. Their performance and reliability have made them the industry standard for determining oil and grease concentration levels in water – both for on-shore and off-shore use.
Reader Reply Card No. 81 Rapid Changes in Biogas Analysis
Biogas analysis requirements are changing. Designed for future proofing in gas analysers helps users keep up. It means they can quickly and easily upgrade their newly purchased products with new features anywhere in the world, anytime with online downloads available from Geotech (UK).
Positive global customer feedback on the new Geotech range of biogas and landfill gas analysers launched in early 2012 prompts the second set of new developments. This Geotech rapid response on the GA5000 landfill gas analyser and the BIOGAS 5000 especially suits users in countries with changing operational and legislative conditions.
Commenting Geotech sales manager, Simon Sheridan, said, “At Geotech we are dedicated to listening to our users and our distributors in every country and responding with speed to supply gas analysis with the capability they specifically need. That is very evident from these new enhancements. Our continued developments, packaged up as a single download, ensure we are meeting the needs of widely varying applications.”
Landfill gas analyser users can now optionally analyse up to six gases with the GA5000. Analysis of methane (CH4), carbon dioxide (CO2) and oxygen (O2) is standard and the choice of options includes carbon monoxide (CO), hydrogen sulphide (H2S) and hydrogen (H2).
The new faster operational sequence offers greater efficiency and productivity through monitoring more wells and achieving more readings each day. Users can choose to have users prompts on or off and or a very quick ‘simple gas’ reading option.
Users can now have up thirty sample-point IDs on the display screen in easy-to-read grid view, up from five IDs before. That helps with increased speed for users while maintaining precision and accuracy in operation.
Specially developed for research/pilot plant studies, universities and research institutes, data logging enables continuous timed monitoring of mixed-gas output. Geotech has now added this to its 5000 range of portable landfill gas and biogas analysers and already offers this on its CO2 gas analysers for incubator verification and the nitrous oxide (N2O) medical gas analyser range.
Reader Reply Card No. 82 Standard-Compliant Measurement of Electric and Magnetic Fields
Narda Safety Test Solutions (Germany) presents two new meters for equipment that operates using industrial frequencies. The devices make standard-compliant measurements of electric and magnetic field strength to determine the degree of exposure to electromagnetic radiation and demonstrate adherence to human safety regulations.
The Narda Industrial Field Meters NIM-511 and NIM-513 are complete hand-held measuring systems consisting of a basic unit and a measuring probe equipped with electric and magnetic field sensors. They provide an inexpensive solution for the task of checking the compliance of industrial plant with regulations and limit values for electromagnetic radiation.
The NIM-511 sensors cover a frequency range from 300 kHz to 100 MHz and are balanced during calibration at the 13.56 MHz ISM frequency often used in semiconductor manufacturing, for example.
The NIM-513 sensors cover the range 10 MHz to 42 MHz and are balanced during calibration at the 27.12 MHz ISM frequency – the frequency most often used for heat welding equipment and induction ovens.
True to task, the NIM devices are compact, weigh just 600 grams, and are easy to use. Since the probes measure the electric and magnetic fields at the same time, there is no need to switch probes, saving a lot of time when making measurements. Automatic measurement range selection, auto-zeroing, clear operating mode display, and a digital result readout make for reliable results and practically eliminate mistakes in measurement.
