In some embodiments, a level not shown may be provided to verify that the flask 18 is parallel to the surface upon which the apparatus 10 rests.
Process to prepare a paraffin wax according to claim 6, the process at least comprising the following steps:. Moreover, current practices provide no standard means of ensuring that multiple operators are rotating the flask at the same speed.
Properties of fraction M can be found in Table 1. Typically, the Saybolt colour scale is used to quantify colour intensity for mildly coloured substances in liquid state. US USA1 en These are distilled into the individual carbon fractions or carbon fraction blends.
Add to Alert PDF. Typical hydrogenation conditions for hydrogenation of the above fractions are described in e. To prepare the wax-containing sample for testing, the method includes the steps ofheating a sample flask to a predetermined temperature in a heating unit;heating the wax-containing sample to the predetermined temperature in the heating unit;immersing a temperature sensor in the wax-containing sample;removing the sample flask from the heating unit;removing the temperature sensor from the wax-containing sample, while retaining in adherence thereto a droplet of the wax-containing sample;inserting the temperature sensor into the sample flask; and inserting the sample flask into a mounting clamp of an apparatus for determining the congealing point of a wax-containing sample.
A new separation process for polyolefin resins.
In some embodiments, the motor rotates the clamp at a speed of less than 50 RPM. Add to Alert PDF. In some embodiments, the battery is mounted within the housing Although the approach disclosed herein can be applied to a variety of sample test methods, the present description will primarily be directed to apparatus and methods for determining the congealing point of a d38 sample, such as a petroleum wax-containing sample.
As shown, laboratory thermometer 34 includes a stem portion 36 and a bulb For this objective waxes are molten for measurement. Alternatively, in some embodiments, the x938 of power is direct current.
In one aspect, disclosed herein is an apparatus for determining the congealing point of a wax-containing sample, such as a petroleum wax-containing sample, the sample placed within a sample flask, comprising: Such amended or new claims, whether they ashm directed to a different invention or directed to the same invention, whether different, broader, narrower, or equal in scope to the original claims, are also regarded as included within the subject matter of the inventions of the present disclosure.
Caution should be taken when handling dd938 and mercury containing products. Standards Subscriptions from ANSI provides a money-saving, multi-user solution for accessing standards. Need more than one copy? In some embodiments, the asrm may be mounted on the hinged cover 44 of the housing Fraction 20 is fed to a hydrogenation reactor 3 wherein fraction 20 is converted to a hydrogenated fraction Preferably, the Fischer-Tropsch derived paraffin wax comprises more than 85 wt.
Referring especially to FIG.
Further, the paraffin wax according to the present invention has a Saybolt colour according to ASTM D of at least 25 cm.
The semi-automatic apparatus eliminates the use of hands d9388 rotate the sample. Waxes are organic substances that tend to be solid at ambient temperature and become free-flowing at elevated temperatures. A paraffin wax according to any one of claims 1 to 3, having a Saybolt colour according to ASTM D of at least 30 cm. The separation is preferably performed by means of a distillation at atmospheric or slightly below atmospheric pressure conditions.
Mercury, or its vapor, may be hazardous to health and corrosive to materials.
The composition of montan wax varies geographically with production, but includes varying amounts of wax, resin and asphalt. The apparatus, methods and various embodiments disclosed herein are further illustrated by the following non-limiting Examples.
ASTM D – 04 Standard Test Method for Congealing Point of Petroleum Waxes, Including Petrolatum
Process for increasing the yield of lubricating base oil from a Fischer-Tropsch plant. For the purpose of this description, a single reference number will be assigned to a line as well as a stream carried in that line. The apparatus and methods described herein provide laboratory technicians and scientists with an ergonomic improvement over manual test methods by eliminating risk of repetitive stress injury RSI from constantly resetting the wrist to rotate the flask.
In some embodiments, temperature sensor 32 may be a laboratory thermometer In another aspect, disclosed herein is a semi-automated method for determining the congealing point of a wax-containing sample, such as a petroleum wax-containing sample.
This is a significant improvement over the manual method due to the elimination of potential c938 stress injury RSI. As the voice of the U. According to the present invention, a paraffin wax has a congealing point according to ASTM D of at least.
