Detecting Benzene in Refinery Atmospheres

Benzene remains an important industrial chemical but is well known as extremely hazardous and recognized as a carcinogen. Detecting benzene in the refinery is important as legislations across the globe have been put in place to ensure exposure of benzene at plants where it is produced is minimized. Modern PID instruments offer the means to monitor benzene concentrations down to 10ppb or better.

Benzene is a natural constituent of crude oil. Assuring the safety of personnel working on oil refineries generally in the extraction of benzene, in particular, depends on keeping exposure within tightly specified limits. European law requires that benzene exposure at refineries be reduced as far as is practically possible, with levels no higher than 1ppm averaged over a time-weighted average (TWA) eight hour day, or 5ppm for 15 minutes as a short term exposure limit (STEL). This proves how vital detecting benzene in the refinery is! Production facilities must monitor pipework, seals, and valves, and measure emissions from process equipment. Similar regulations exist in the USA and in fact in most jurisdictions.

One of the aromatic hydrocarbons, benzene is extremely hazardous. The immediate effects of high exposure include headache, dizziness, nausea, and tiredness, while long term exposure to excessive levels is a direct cause of leukemia. As well as being a known carcinogen, benzene is also associated with various blood disorders (such as anemia) and pre-cancers of the blood. It also attacks the liver, kidneys, lungs, heart, and brain, and can cause DNA strand breaks and chromosomal damage. But benzene is also an industrially important chemical, being an intermediate in the manufacture of various plastics, nylon, resins, and various pharmaceuticals. As such it is separated from other hydrocarbons as part of the petrochemical refining process in many plants and extracted as raw benzene. Monitoring of benzene is best performed with PID using a three-stage process. The first stage is to monitor concentrations of total aromatic compounds (TACs) using a selective 10.0 eV lamp, with no pre-filtering for benzene. If this TAC value is within the 1ppm limit, then benzene concentrations must therefore be within the 1ppm limit. If the TAC level is higher than the 1ppm limit, then stage two is to filter out the hydrocarbons that would interfere with the detection of benzene and then test again. If the level of benzene is below 1ppm, then again all is well. If it is higher, then the final step is to perform a 15-minute STEL test.

The Tiger Select from Ion Science is a revolutionary hand-held gas detector with two-mode operation for the rapid detection of benzene and total aromatic compounds. The most sensitive such device available, the Tiger Select is capable of providing both 15-minute STELs and 8 hour TWAs for TACs using its proprietary high output 10.0eV lamp.

With the Tiger Select, a reading is shown for TACs immediately on start-up. Should aromatics be detected, a benzene pre-filter tube can be easily attached for rapid stage-two and stage- three detection and selective measurement of benzene down to concentrations of parts per billion. In addition, the unique MiniPID sensor incorporates both Anti-contamination and Fence Electrode technology for extended operation in difficult working conditions.

History shows us that legal concentration limits for exposure to hazardous chemicals only ever trends downwards.
