Use of Diaphragm pumps in Sampling systems
INTRODUCTION Sample system design can take many forms, influenced by factors including cost, size, maintenance, source conditions, and analyzer requirements – to mention a few. The following discussion takes into account the operating characteristics of a diaphragm pump, and choices that will improve system performance, reduce measurement errors, and lower pump maintenance. Illustrated below ...

Sampling of Pumps and Pump Systems
Manufacturers of pumps and assemblies are usually faced with the challenge of accurately measuring complex components with internal contours, such as flow channels inside impellers or pump housings with their complex geometries. Sophisticated geometry is an important aspect in determining the level of pump efficiency that can be achieved. This is essential for our customers, as it determines the ...

Gas Monitoring for Ventilation Control and Energy Management
The growing demand for underground and enclosed parking and maintenance garages (resulting from limitations on land availability) has increased the awareness and need for proper ventilation and control systems. In addition, increased health and safety programs have only added to the concerns of toxic and combustible gases in confined or enclosed spaces. Historically, ventilation and make-up air ...

Case study - chroma S Sulfur compounds analysis (H2S and CS2, 0/300ppm) for emission application in a paper mill
Paper mills use large quantities of sulfur substances in particular in the process of cellulose burning (Kraft cooking). CS2 and H2S emissions are a real problem for the environment (toxicity, odors...). Nowadays, emissions are submitted to regulations (Directive n° 2001/81/EC of European Parliament and Council October 23, 2001) and factories must respect these rules by installing filter or ...

A new no-purge, non-displacement groundwater sampler
What Is It? The HydraSleeve sampler is designed to collect representative water samples from monitoring wells without purging. The disposable sampler collects a discreet sample from only the 'fresh formation' water in the screened interval of the well. It is fast, inexpensive, simple to use, generates no purge water and collects a sample suitable for all analytical parameters. Why It Works The ...

Scanning success - Case Study
Scanning Success: A multiparameter analyzer helps a Kentucky treatment plant step up to the plate and meet a new phosphorus limit in its permit In 2001, the Lexington Fayette Urban County Government West Hickman Creek Wastewater Treatment Plant in Nicholasville, Ky., was starting Phase II of its third upgrade since 1972, when the state imposed a phosphorus limit. Total phosphorus hovered around ...

Performance Testing of Conventional and Innovative Downhole Samplers and Pumps for VOC`s in a Laboratory Monitoring Well
Untitled Document ABSTRACT Concentrations of groundwater contaminants in samples that differ from concentrations in the aquifer can lead to incorrect conclusions about the extent and severity of contamination and the effectiveness of remedial measures. Sample collection and storage techniques affect measured concentrations in samples, particularly of organic compounds that ...

Gas detector communication technology for offshore oil and gas platforms
In few applications is safety as important as on offshore oil and gas platforms. Explosive hazards from hydrocarbon gases and vapours are an ever-present risk, whilst toxic hydrogen sulphide gas and depleted oxygen environments can pose significant risks to personnel. Gas detectors are therefore essential to provide dependable early warning of gas hazards. Gas detectors are permanently installed ...
