We are honored to introduce a new type of oil online analysis system to you. The basic design concept of this system is to enable users to improve comprehensive economic benefits while solving maintenance problems of the online system. This new generation of online analysis system utilizes patented artistic design and unique technology for precise monitoring of phase changes. The same monitoring method is also applied to Phase's laboratory analyzer. There is no deviation between the online analysis results and the laboratory analysis results.

In the fiercely competitive petroleum product market, increasing the production of aviation fuel and diesel can directly enhance your market competitiveness as well as reducing production costs. PHASE's online analyzer can increase profits by reducing product waste, reducing on-site equipment usage time, and lowering water consumption. At the same time, it can strengthen the control of the process, increase process output, and provide accurate measurement methods for your quality control laboratory.

• Optimize your refining process through fast, reliable, and real-time product flow detection

• Maximizing the output of high-value products and reducing losses

• Strengthen quality control by linking with the main testing methods

• Benefit from robust design with continuous and uninterrupted measurements

Widely used

The success of Phase Technology's refining process analysis system lies in its sample control system Aquanot. Each Aquanot is controlled by a program, and the operator can choose parameters such as the flow rate of the filtered sample, the frequency of sample calibration, and the cycle of automatic cleaning. Aquanot can filter samples containing ultrafine particles and a moisture content of 35% or higher. It can effectively separate impurity particles, free water, and bound water in the sample, and provide sufficient sample volume for most online analysis systems for gasoline/naphtha and distillate fractions. Aquanot's explosion-proof design makes it also suitable for installation in hazardous areas.

Durable and effective

The main problem with most refining process analysis systems is the lack of suitable sample control systems. The success of Phase Technology and Aquanot lies in their patented anti blocking device, which utilizes the energy of compressed samples to flow backwards through the filtration membrane, allowing the membrane to operate clean and fault free for several months without maintenance. At the same time, the filter membrane also uses special pore geometry design to facilitate the backwash operation of the sample. Optimize the size and flow rate of the pores to ensure that the filtered sample can continuously flow towards the analysis device.

Apply mature technology to critical systems

Each Phase Technology online analysis system is equipped with patented sample control systems and sample recovery systems to measure the freezing point of aviation fuel and the pour point, pour point, and cloud point of distillate. You only need to provide basic equipment, signal cables, and sample streams. This system is designed to be used in harsh and dangerous environments. Similar to Phase Technology's laboratory analysis equipment accredited by ASTM, the online analysis system utilizes state-of-the-art electronic technology to directly measure freezing point, pour point, pour point, and cloud point. No need for valuation readings, no need for calibration, and no use of external refrigeration equipment. The proven accuracy of this technology provides effective guidance for fine-tuning process conditions and optimizing mixing compositions.

Operating principle

The most basic principle is to continuously detect the changes in the sample at a set temperature. A small amount of sample (0.15mL) was injected into a sealed container with chromium as the reflective surface. The visible light beam was directed towards the sample at a specific angle, and when no crystals were produced, the incident light was reflected onto the black surface of the test container. The base of the light sensor is vertically placed on the surface of the sample, and it can detect the faint light reflected from the wax crystal surface at any position of the entire sample.

The sample is cooled by a patented electronic cooler, which can provide precise cooling. The cooling and heating rates strictly comply with ASTM methods. Using a temperature sensor as a feedback device, the built-in microcomputer accurately controls the sample temperature and detects the time of crystal appearance and disappearance. At the end of the test, the wax must be removed from the sample before it is automatically cleaned. The test results are converted into 4-20mA signals and displayed in digital form.

Maintenance and technical support

All systems are designed with minimal maintenance in mind, including three subsystems: sample control system, analysis system, and sample recovery system. Each system can be replaced independently or repaired with simple tools. The design of the entire system has been fully proven to be reliable. Every time a fault is resolved, the system can be controlled by technicians from a remote refinery through a modem. From design to installation, Phase strives to provide the most comprehensive services for the refining industry.
