Low Vapor Pressure Liquids

This group of process liquids has a vapor pressure < 19 psia and will not generally vaporize under normal atmospheric conditions. Samples in this group are caught in bottles with a cap and septum sealing system used to capture venting and eliminate spilling of the sample during transport to the lab. The sample valve design provides for excellent flow control during filling, reducing the potential of operator or environmental exposure.

The SENSOR Basic Bottle Sampling System (BBSS), is a closed loop sampling system utilizing a unique flow-thru valve design that simplifies the sampling process by eliminating additional operations in order to grab a sample. The design allows for sample collection, venting and nitrogen purge within the interior of the sample valve. The valve design allows for virtually NO dead volume when used in conjunction with the SENSOR Needle Purge (SNP) option. 

For process pressures > 175 psig the SENSOR Fixed Volume Sampling System (FVBSS) is perfect for handling hazards that tend to compound with increased operating pressures. The sampling systems is designed to isolate the operator from the process pressure, while blowing the sample into the bottle at N2 purge pressure, usually set to 6 psig.

These closed loop sampling system types can be used to sample a wide variety of chemicals and petrochemicals where there is concern for personnel exposure and environmental impact. Sampling components can be fabricated from 316L SS, Hastelloy C276, Monel and other similar types of materials.

Typical SENSOR BBSS applications would include; amines, benzene, ethylene di-chloride (EDC), hydrochloric acid (HCl), sulfuric acid, hydrotreating, gas oils, naptha, sour water, caustic, residuum (Resid), asphaltenes, hot tar, condensate, vacuum tower bottoms, reformate and many other chemical compounds.
