Intertek’s crude oil assay laboratories provide clients with professional, independent, and impartial crude oil quality data needed to make beneficial commercial trading and refining feedstock decisions. For larger stills, the residue can be discharged through aetm charging qstm using a positive pressure of about 10 kPa in the still. It is most important that at the time of first use of a new apparatus, its components be checked as detailed in Annex A1 and Annex A2 and that the location of the vapor temperature sensor be verified as detailed in 6.

If the corrections obtained differ by more then 0.

Distillation Combined semi-automatic ASTM D2892 / D5236

Allow the system to stabilize for at least 2 min. Users must determine legality of sales in their location. Preparation of Apparatus 8.

Zstm Reach Intertek is the industry leader with over 42, people in 1, locations in over countries. It is most d52336 that at the time of first use of a new apparatus, its components be checked as detailed in Annex A1 and Annex A2 and that the location of the vapor temperature sensor be ashm as detailed in 6. If the reblending is done in the original flask, this flask can be used for the subsequent distillation. Testing Evaluating how your products and services meet and exceed quality, safety, sustainability and performance standards.


Although these data do not meet the statistical requirements of RR: D, due to the time and cost involved it is unlikely that an additional cooperative program will be initiated soon. A smooth curve through this plot constitutes the final distillation curve.

For the boiling point of water, use an equilibrium still or ebulliometer, a Tensimeter as shown in Fig. However, distillation curves and fraction qualities obtained by these methods are not comparable. The rings of O-ring joints should be made of Vitron-A5, or silicone of equivalent hardness, and be lightly lubricated. If they agree at the test pressure, it is an indication that the system is free of moisture and other condensables.

It shall have a response time of less than 60 s as described in Annex A1. Allow the sensor to reach equilibrium temperature.

The mass percent of water is calculated.

Need help or have a question? Addition of heat to the flask to maintain product rate should be done with great care. The pumping line can be made of heavy-walled rubber or light metal tubing, but its inside diameter must be greater than half the inside diameter of the outlet of the condenser and less than 2 m long.

ASTM D – Pilodist

This will take 2 to 10 min depending on the amount of material in the flask. A suitable manual device is illustrated in Fig.

Assurance Enabling you to identify and mitigate the intrinsic risk in your operations, supply chains and business processes. However, automatic d5326 controllers tend to mask these phenomena. The size of the charge for each size of still is determined from the loading factor. A suitable leak test is to pump down to a pressure below 0. It shall be kept filled with crushed dry ice at all times while in service. The sample can also be aastm residue from Test Method D Warning—Mercury vapor is poisonous.


A heat density of 0. It provides an estimate of the yields of fractions of various boiling ranges. The recommended loading factor is between and mL of charge per square centimetre of cross sectional area in the neck of the head.

Usually two or more circuits are used to improve heat control by applying automatic heat to the bottom circuit. The potential exists that selling mercury or mercury-containing products, or both, is prohibited by local or national law. It is recommended that these stills be kept in an enclosure to ensure that in case of an implosion, the operator and others nearby are protected from flying debris, but that the front, at least, be transparent and removable for access to controls and so forth.

The edges shall be rounded to minimize grinding the wall of the flask. While the practice of reblending distillates with residue can be done to produce a lighter residue, it is not recommended because it produces blends with irregular properties. Certification Formally confirming that your products and services meet all trusted external and internal standards.

Weigh by difference to the nearest gram, the required volume of wet sample into a distillation flask containing a magnetic stirrer.
