Automatic determination of the coagulating point of coagulants
Pour point depressant refers to the chemical that can reduce the freezing point of lubricating oil, which is generally polymer organic compound. Many varieties of pour point depressant are the same as those of oil and gas. Lubricating oil in common varieties are alkyl naphthalene, poly methacrylate, poly A - olefin and so on. Among them, polya-olefin (code T803) is a new type of light color point depressant developed in 1970. The olefin was decomposed with soft wax as raw material, and after proper refining, the polymerization was carried out in the presence of Ziegler-Natta catalyst. The molecular weight was adjusted by H2, and the catalyst was removed by esterification and water washing.
Freezing point (freezing point) refers to the oil under the specified conditions, cooling to the liquid level does not move the high temperature, expressed in ℃. The same number of carbon atoms:
(1) n-alkanes & GT; Aromatics with long side chains & GT; Naphthene & gt; Isomeric alkane.
(2) Diesel water content exceeds the standard, the freezing point will be significantly increased.
Determination of freezing point according to GB/T 510-1983 (1991) "Determination of freezing point of petroleum products". Suitable for determining the freezing point of dark petroleum products and lubricating oil. SH113E1 automatic freezing point tester is based on the national standard national standard GB/T510 "petroleum products freezing point determination method", the use of modern advanced technology, set of mechanical, optical, electronic and computer technology in one, can automatically complete the testing of petroleum products freezing point, this instrument uses photoelectric detection technology, glass tube automatic tilting method, The imported compressor refrigeration system ensures the required refrigeration depth.
