Closed Loop Sampling Systems

Safe-Reliable Sampling Made Easy for All Applications         Application Photo Library

SENSOR closed loop Sampling Systems are specially designed and manufactured for the chemical hydrocarbon processing industry to mitigate potential hazards that exist with extracting representative grab samples. They are designed and constructed to meet the industry requirements for environmental and emissions standards. Manufactured in Houston, the heart of the industrial Gulf Coast in Texas, Sampling Systems are required to manage quality, yield and other important aspects of chemical and hydrocarbon processes.

These grab sample stations are used to retrieve safe, representative samples by utilizing special sample valve technology and by capturing the vent to protect operators from hazardous or lethal compounds present in refining and chemical processes. Closed loop Sampling Systems are designed and built for specific applications including; naptha, heavy gas oil, resid, hydrotreaters, desalters, H2S detector tube, vacuum tower bottoms, refinery gas, hydrogen, propane, butane, pentane, ethylene, EDC, VCM, HCL, H2SO4, NaOH, HF, phosgene, organic acids, HCN, ethylene oxide, propylene oxide, olefins, styrene monomer, ethylbenzene, organic akyls, amines. Grab sampling is performed by utilizing a fast loop to eliminate dead volume and produce a representative sample of the production process. Closed loop Grab Sampling Stations are designed to provide zero emissions, zero dead volume and sample integrity, without negatively impacting the environment or operations personnel.

SENSOR Sampling Systems complies to PED 2014/68/EU on all systems with requirements conforming to this directive. As part of PED Article 4.3, it calls out anything below requirements of volume and pressure be built using Sound Engineering Practice (SEP) to ensure safe use and as such markings “Without prejudice to other applicable Union harmonization legislation providing for its affixing, such equipment or assemblies shall not bear the CE marking when referred to in Article 18.” Therefore, when SEP is used, the device will not hold a CE marking. In most cases due to the lower volumes and pressures required in sampling systems, SEP will be the prevailing requirement. In other instances where process conditions drive past the SEP mode of operation, all requirements of PED will be administered while working with the Notified Body. For removable components for transportation of collected sample such as collection cylinders, TPED compliant components can be supplied when required.
