Gas & Liquefied Gas Sampling Systems

Gas sampling systems with sample cylinders

Spot Sample Stations for Gas and Liquefied Gas.

Mechatest design standard and custom made gas or liquefied gas spot sampling systems that can take spot samples of gasses, liquefied gas or flashing fluids under process conditions in sample cylinders.

The systems with sample cylinders enable operators to obtain samples of gasses with high process pressures, liquefied, hazardous or toxic gasses.

  • Sample volumes cylinders 150, 300, 500, 1000 and 2250 ml (other on request)
  • Max. Process Pressure 124 barg (1800 psig), 345 barg (5000 psig) or 689 barg (10000 psig)
  • Safe (sampling) Process Temperature 60°C (140°F), high temperature with sample cooler
  • Complete sampling systems available in 316 stainless steel, Monel, Inconel, Incoloy, Hastelloy, Duplex (other on request)
  • Cylinders conform European “Transportable Pressure Equipment Directive 99/36/EC” (TPED) or “Shipping Container Specifications” DOT from the U.S.
  • One-handle operation by multiple valves guarantees simple operation and easy sample taking without complicated sampling procedures
  • Purge options available
  • Sampling systems with NACE MR0175 or NACE MR0103 standards for sour gas (H2S) applications.

Gas or liquefied gas sample panels/stations, standard designs and custom made conform client specifications. Sampling systems for Gas or Liquefied Gas Applications, for high pressure, low and high temperature, corrosive, arduous and sour service, strong toxicity, strong volatile and dangerous liquid gas mixture or gas which is bane to the environment.

  • Closed Loop and Emission Free Sampling
  • Safer for the operator and environment, prevent pollution
  • Safer for the sample and safe sample
  • Easy in operation and Low maintenance
  • Spring Return Handles available for Swagelok, Fitok and Hoke ball-valves.
  • Options: Spring return handle on sample valve, panel-mounted and protection cabinets with heater, floor-stands, special elastomers on request, all kind of process connections, sample coolers

VOC Detection in sample cabinet

Oil installations, petrochemical plants and refineries are industrial sites that manage several raw materials (crude oil, natural gas, chemical intermediates, etc.), thus having great impact on the environment. Industrial processes may generate VOC emissions to the atmosphere, so prevention and control is becoming a very important issue in the petroleum industry.

Mechatest deliver VOC detection systems to include in our sampling system cabinets, read more about the possibilities of VOC monitoring detection systems.

Mobile (portable) gas sampler with vacuum pump Mechatest Sampling Solutions

If there is no posiblility (for any reason) to place fixed mounted sampling points, the mobile (transportable) sampling solution is the better choice for you!

This is a custom made and money safe solution, we design for every application a portable sampling system for gas or liquid sampling.

Mobile (transportable) sampling solutions carry with easy a several sample cylinders to the different sample tap points in your plant area.

  • For applications with over-pressure or vacuum, high or low temperature, liquids or gas
  • Optional with vacuum pump for low pressure (vacuum) sample applications
  • Explosion proof
