ASTM D4929

PILODIST PD 4929 S

The new PILODIST PD4929S is an automatic distillation apparatus for the sample preparation according to ASTM D4929.

This standard test method for the Determination of Organic Chloride Content in Crude Oil requires a crude oil distillation up to 204°C with a glass apparatus to achieve the naphtha cut for the chloride content analysis. Prior art is the sample preparation done by a complete manual distillation which time consuming and requires full attention to achieve a correct and precise cut point.  The new PD4929S performs this distillation in an automatic and precise computer controlled process with an apparatus strictly according to the ASTM standard method. A unique cooling system for the distillate receivers allows and easy, safe and quick receiver interchange and the direct storage of the sample in standardized GL45-bottles.

Beside the standard application for the 204°C naphtha cut the system contains an additional receiver with free programmable cut point. This allows integrating additional tests in the same procedure, like the common test method at individual temperatures for mercury content to prevent catalyst poisoning in refineries.

The repeatability and reproducibility of this instrument is outstanding due to the computer controlled process, a calibrated high-precision temperature sensor and an automatic barometric boiling point correction with integrated pressure sensor.

PILODIST 104 BD – 10L

 

The PD104BD is designed for critical and sensitive products and does not contain any metal parts in direct contact with the sample. The system consists of a double jacketed 10L glass vessel with mechanical stirrer drive, precise oil tempered by a dynamic process thermostat. The silvered Distillation column in DN25 made of borosilicate glass can be equipped with various packing materials, depending on the application. A column heating jacket with automatic temperature sequence control ensures adiabatic operation. The column reflux ratio can individually be adjusted using a time-controlled reflux divider.

The system provides the possibility to discharge via tempered lines a fraction into a single receiver or alternatively into a customized fraction collector providing 6 receivers with the possibility to take out a filled receiver during operation without disturbing the vacuum.

The plant is equipped with a high capacity vacuum system and automatic calculation of the AET (Atmospheric Equivalent Temperature) so that the desired product sections can be entered directly without conversion and the reflux divider automatically switches to total reflux when the preselected cut temperature is reached. This ensures a clean separation even when the system is unattended. Equipped with the processor-based distillation control unit DCD4001, all distillation parameters such as temperature, vacuum, reflux distribution and the fraction collector are controlled via the associated software using an IP65 touchscreen PC. Limit value monitoring and security mechanisms ensures a safe distillation.

Via an integrated WIFI connectivity PILODIST is able to provide remote online service whenever needed. The entire system is integrated into an aluminum frame with an optionally available transparent polycarbonate enclosure with front doors as well as a top nozzle for adaption to an onsite available exhaust system.

PETRODIST 100 CC fully automatic, ASTM D-2892 from 50L to 100L

k-Pilodist_15-07-2015_12335_100CC

Processor controlled crude oil distillation system for flask volumes of 50 L and 100 L for fully automatic operation exactly conforming to ASTM D-2892 (TBP), latest revision.

The system is computer controlled and designed for fully automatic operation throughout the different distillation runs at different pressure levels which includes:

  • debutanization
  • run at atmospheric pressure
  • run at vacuum 100 Torr
  • run at vacuum 10 Torr
  • run at vacuum 2 Torr

The system design is based on stainless steel flasks with a drain valve at the bottem for easy discharge of residues. Flask and flask heater are mounted on a movable trolley for easy removal oft he flask and possible exchange with other flask volumes.

The flask content is stirred by a powerful mechanical stirrer to ensure an effective mixing to ensure a smooth evaporation. The system can be equipped with interchangeable different flask volumes .

These different distillation runs are performed automatically without any intervention of the operator. The system automatically manages the changes of all involved operation pressure changes from atmospheric to the different vacuum conditions automatically with. The duration of the intermediate cooling procedure in between the different runs is minimized by an intensive cooling of the flask charge as well as introduction of N2 into the system.

The system measures online the volume of each fraction before each cut is being discharged into an automatic fraction collector with 20 receivers. The fraction collector is equipped with an inbuilt electronic balance to measure the weight of each fraction. By replacing filled receivers the system can handle up to 80 cuts for the distillation of one sample. The receiver change is performed according to pre-selected cut temperatures or when a receiver is filled up to continue the cut sampling in the next receiver (to avoid overfilling of the receiver).

After the distillation the operator needs to weigh the gas trap as well as the flask residue by the external balance (part of delivery), the weights are automatically taken by the system and as a result the final data evaluation and TBP-curves in weight-% and volume-% are printed out and can be stored.

The system can optionally be equipped with an online density measurement system.

The system requires for operation water, nitrogen, compressed air and electricity to be supplied by lab infrastructure.

PETRODIST 300 CC-HT

Fully-automatic high-temperature analysis system

New development from PILODIST for the distillation of high boiling and highly viscous products
with melting points up to 250°C (similar to ASTM D1160)

 



Fully-automatic distillation system with a process similar to ASTM D1160 with an extended temperature range for the determination of boiling ranges of crude oils and other hydrocarbons under atmospheric or vacuum conditions.

The system is equipped with a completely heated distillation line, to be tempered up to 250°C. It includes also a processor controlled high temperature heating chamber with an automatic optical fiber volume follower system to ensure that products with melting points of up to 250°C can be collected into the final receiver without any cristallization. As a result complete boiling curves from initial boiling point (IBP) up to the end boiling point (EBP) can be produced. The process can be realized in different pressure steps for the analysis of products with a wide boiling range.

The high temperature resistant stainless steel column (AISI 316Ti) enables head temperatures of up to 400°C under atmospheric conditions (depending on product). Temperatures of up to 650°C AET can be achieved under vacuum operation.

The heating is performed by an electrical high-temperature heating bath with quartz-glass isolation and a 500 ml stainless steel flask. By using a highly dynamic tempering system for the condenser circulation very fast cooling or heating rates can be achieved so that distillation and cleaning runs can follow in short sequences.
