The Pour Point Process Analyser (PPA-4) measures the pour point of petroleum products, hydrocarbons, chemical products and components.
The Bartec Benke Pour Point Process Analyser operates online and fully automatic. The pour point is the temperature below which a liquid sample will not flow. Jet fuels, diesel fuels, and household fuel oils usually contain small amounts of dissolved waxes which, if they precipitate, could plug fuel filters and fuel pumps.
The Bartec Benke Pour Point Analyser is an on-stream Analyser designed for closed-loop process control. It accurates pour point determinations for diesel, lube and heating oil production.
This is the process of the Bartec Benke Pour Point Analyser. After thorough flushing the measuring cell is filled with the product. The product is cooled after a programmable settle down time. During cooling the measuring cell is tilted every 3 degrees celcius-step-decrease (other steps programmable). As soon as an IR-detector detects a movement on the surface of the product (sensitivity programmable), the measuring cell is moved back to vertical position.
If no movement is detected when the cell has been tilted to horizontal position, the measuring cell is kept in that position for 5 seconds. If also then no movement is detected, the temperature of the previous tilting is stored as the pour point temperature. Then the measuring cell is heated up, flushed and the next cycle starts.
