In order to adapt to the petroleum industry, the petrochemical industry faces issues such as adsorption, hysteresis, and distortion in analyzing sulfur-containing compounds. Specially launchedSilcoTekThe company's acquisition of the United StatestechnologySilcoNert®Thermochemical vapor deposition process (silicon passivation treatment) to meet user needs.IAs a companySolcoTekThe company's agent in China provides silicon steel pipes, silicon passivated pipeline joints, components, injection valves, switching valves, etc. required for chromatographic analysis systems that have been processed by this technology. It also accepts incoming materials and processing services for this technology.

The characteristics of this technology in analyzing sulfur-containing samples are:

lIncrease sulfur andH2SAccuracy of Sampling

lFaster analysis cycle

lInppbContent of sulfur andH₂SAccelerate sampling speed and improve efficiency

SilcoNert^®2000The coating eliminates active compounds such as hydrogen sulfide(H₂S)Surface adsorption of methyl mercaptan or other sulfur-containing compounds.

Accurately analyze petrochemical processes or underground processes that containppmorppbSulfur-containing compounds such asH2SThe properties of the contact surface with methyl mercaptan are crucial. If left untreated, many sulfides, such as hydrogen sulfide(H2S)Methyl mercaptan and ethyl mercaptan will be adsorbed on the metal surface in contact.

Using the classicsSilcoNert(R)The processing of sulfur-containing samples can ensure their accuracy

lDetecting high cost process fluctuations in a short period of time

lThe sample and all contact surfaces can prevent the influence caused by the catalyst

lComply with strict requirements of analytical procedures

lsatisfy1118Requirements for standard methods

lStandard determination applicable to ultra-low sulfur diesel and gasoline

When this technology is compared with sample columns used in refineries or underground sampling,SilcoNert 2000The sulfur detection capability of the processed sample column is significantly improved. The sample column exhibits excellent sulfur content/ H₂SInert and capable of reliably storing low levels of active sulfur compounds for a long time. By contrast,H₂SQuickly degrade in untreated columns and24hourInternally adsorbed.

SilcoNert 2000®is a kind of(American Technology#6,444,326)Silicon, chemical vapor deposition(CVD)Coatings specifically designed to improve the sulfur and chemical inertness of steel, stainless steel, alloys, glass, and ceramics.

SilcoNert^®2000Coatings can adapt to the most complex surfaces while maintaining high precision tolerances. This coating can achieve radius bending with the deformation of the pipeline surface, and will not interfere with threaded or compression joints;This makesSilcoNert2000Coatings have become an ideal choice for process sampling, oil and gas extraction, and downhole sampling.

During the transportation of samples: hydrogen sulfide(H₂S)Other sulfur compounds will adsorb onto the surface of the pipeline
