System for remote transmission of spectral information through communication optical fibers for real-time on-line hydrocarbons process analysis by near infra red spectroscopy

A system for remote real-time spectral analysis of a hydrocarbon comprising:

• (a) a light source for generating light radiation;
• (b) an optical probe head being at on-line contact with an analyzed hydrocarbon sample, wherein said optical probe head includes a sample cell for accommodating said analyzed hydrocarbon sample, said cell includes a top and a bottom, a hydrocarbon inlet, a top hydrocarbon outlet located at said top and a bottom hydrocarbon outlet located at said bottom, said bottom hydrocarbon outlet is narrower than said top hydrocarbon outlet and serves for removal of pollutants accumulating at said bottom, such that pollutants are at least partially removed from said top of said cell and such that said passing of said radiation through said hydrocarbon sample is through a pollutants reduced zone;
• (c) at least one transmitting optical fiber for inputting said light radiation into said optical probe head, such that said radiation passes at least once through said hydrocarbon sample and a spectrum of said hydrocarbon sample is generated;
• (d) a detector for analyzing said spectrum, said detector and said light source being part of an analyzer;
• and
• (e) at least one receiving optical fiber for receiving said radiation after said passing of said radiation through said sample and inputting said radiation into said detector.
