Sitelab's TD-500D analyzer is used on offshore oil platforms to test TPH in produced sand. The sand is contaminated by crude oil and must be treated prior to overboard discharge in order to meet regulatory limits.
Naturally occurring organics in raw water are typically removed with chemicals. Total Organic Carbon (TOC) analyzers in the water treatment system can alert technicians when generic organic material is present but cannot differentiate between natural organics, such as algae or decomposed plant matter, and hydrocarbons. Using UV fluorescence technology, a properly configured TD-4100XD can alert operators to upsets caused by hydrocarbons such as gasoline, diesel, fuel oil, and crude oil.
Total petroleum hydrocarbons (TPH) is a term used to describe a large family of several hundred chemical compounds that originally come from crude oil; the main and most specific part of these compounds are non-polar and slightly polar hydrocarbons of the aliphatic, aromatic and alicyclic structure. These compounds are harmful to humans and animals if absorbed through the skin, ingested, and inhaled thus claiming the analytical control of THP content in water as a global issue.
Quantification of TPH in water is...
Most chemical products as we know today are composed of a few hundreds of basic chemicals, extracted mostly from crude oil and natural gas. Operators of chemical and petrochemical processes understand the importance of process optimization, and understand the impact of instrumentation and analyzer systems.
