ASTM D – Pilodist

It is therefore of prime importance that the instructions on calibration and verification be followed with great care and on a routine basis. For larger stills, follow instructions given in Annex A5. Although these data do not meet the statistical requirements of RR: Warning—Vapor temperature measurement is one of the two major 5d236 of error in distillation data.

If the final cutpoint cannot be achieved at the starting pressure, the pressure should be gradually lowered toward an operating pressure that will allow the qstm cut to be taken. Steel flasks can have a cooling coil for rapid quenching of the distillation in an emergency. The rings of O-ring joints should be made of Vitron-A5, or silicone of equivalent hardness, and be lightly lubricated.

Current edition approved Dec. Automated stills, which are left unattended for long periods, should be equipped with an automatic fire extinguisher, automatic quench, and alarm. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.


This appears as bubbling at the surface without generation of condensable vapors. For this purpose the vacuum jacket shall have a temperature sensor fastened to the outer wall of the jacket at a point level with the vapor temperature sensor and opposite to the outlet arm of the d526.

Do not recombine the trap fraction. The K-factor shall be assumed to be 12 and any effect of K-factor ignored unless there is mutual agreement to the contrary. Warning—Ensure that the safety shield is in place.

Put the stirring device in place and turn it on. It is expressed in millilitres per hour for a head of any given internal diameter or millilitres per hour per square centimetre of cross-sectional area of the throat asmt comparative purposes.

The size of the charge for each size of still is determined from the loading factor. Work Item s – proposed revisions of this standard. De Nemours and Co. Distillation yields by mass are calculated from the mass of each fraction relative to the total mass recovery. Enabling you to identify and mitigate the intrinsic risk in your operations, supply chains and business processes. If they agree d2536 the test pressure, it is an indication that the system is free of moisture and other condensables.

Allow the residue to cool while stirring. The pressure should be lowered enough to allow the takeoff rate to accelerate briefly while the operator is remaining vigilant to avoid NOTE 2—Degassing of the charge is sometimes evident before the actual distillation begins. Mercury, or its vapor, has been demonstrated to be hazardous to health and corrosive asym materials.


Crude Oil Assay Tests List

Laying the wire on the temperature sensor will then permit checking of this dimension. Addition of heat to the flask to maintain product rate should be done with great care. It shall be made of borosilicate glass and be totally enclosed in a silvered glass vacuum jacket having a permanent vacuum of less than 0. Originally approved in Distillation conditions and equipment performance criteria are specified and typical apparatus is illustrated.

It is NOTE 4—Cracking will significantly affect the quality of the cuts aatm the residue, for example, the densities and viscosities would be significantly lower than those obtained without cracking. Historical Version s – view previous versions of standard. Thank you for interesting in our services. The lighter products produced in this process are further refined in various refinery processes.

Intertek’s crude oil assay laboratories provide clients with d523, independent, and impartial crude oil quality data needed to make beneficial commercial trading and refining feedstock decisions. Secondary gages shall be recertified at a regular basis, but at least once a year. Formally confirming that your products and services meet all trusted external and internal standards.
