Sulfur content detection instrument for gutter oil and swill oil

The UV fluorescence sulfur analyzer produced by Jiangsu Haihuan Instrument Equipment Co., Ltd. mainly uses the UV fluorescence method to determine the sulfur content in gutter oil and swill oil, which improves the ability to resist impurity interference, avoids the complex operation of the titration cell by the electric method and the unstable factors caused by it, and greatly improves the sensitivity of the instrument. The key components of the system are imported, and the detector is designed to prevent light and air leakage, ensuring reliable performance of the entire machine. The implementation standard is based on SH/T 0689-2000 Determination of Total Sulfur Content in Light Hydrocarbons, Engine Fuels, and Other Oil Products (UV Fluorescence Method) ASTM D 5453-2006.

SH-2000SSulfur content detection instrument for gutter oil and swill oilThe working principle is that gutter oil and swill oil are introduced into a high-temperature cracking furnace and undergo oxidation cracking, where the sulfides are quantitatively converted into sulfur dioxide. The reaction gas is carried by the carrier gas and dehydrated by a membrane dryer before entering the reaction chamber. In the reaction chamber, sulfur dioxide is converted into an excited state of sulfur dioxide (SO2 *) after being irradiated with ultraviolet light of a specific wavelength. When SO2 * transitions to the ground state, photons are emitted and received by a photomultiplier tube. After amplification by an amplifier and data processing by a computer, it can be converted into an electrical signal proportional to the light intensity. Under certain conditions, the fluorescence intensity generated in the reaction is proportional to the amount of sulfur dioxide produced, and the amount of sulfur dioxide is proportional to the total sulfur content in the sample. Therefore, the total sulfur content in the sample can be determined by measuring the fluorescence intensity. Before analyzing the sample, use a standard sample that is close to the sample to create a calibration curve. Then, analyze the sample under the same conditions. The program automatically calculates the sulfur content of the sample based on the calibration curve of the standard sample.

The sulfur content detection instruments for gutter oil and swill oil can be equipped with liquid samplers, as well as solid samplers and gas samplers that can be supplemented. The operation is based on the Chinese operating interface of Windows (7, XP), making the operation more convenient and fast. At the same time, the instrument has a self diagnostic function and can perform various data processing simultaneously to calculate values.

Nowadays, the overflow of gutter oil and swill oil is an open secret, and we should do a good job in testing and improve the hardware strength of equipment. After all, we are human beings, and going out to eat or buy oil has become a normal part of our lives. Therefore, strict testing should be carried out for gutter oil and swill oil.

With the development of technology, we have endowed gutter oil and swill oil with more meaning for their survival. It can be used to make fuel and combustion aids, which will make our lives more convenient. Fatty acid series products are widely used in industry, and gutter oil and swill oil can be sold to chemical plants as important raw materials for producing fatty acids, which are then used to produce industrial fatty acid products. In this case, the detection of sulfur content is absolutely necessary.
