Natural Gasoline. Natural gasoline is produced from wet natural gas or from casing-head gas by compression or by absorption under pressure. Adsorption on carbon is another method of producing natural gasoline, but is little used in this country. Natural gasolines commonly are composed of C4 to Cs hydrocarbons. 

Casing head gas derived from an oil well by extraction at the surface. Note Some natural gas contains substantial amounts of helium, nitrogen, and carbon dioxide. 

Inasmuch as oxidized petroleum is more difficult to ignite, it had been decided not to try to inject air into the ignition well (No. 833). Instead, 18 m of crude oil was forced into the formation in order to saturate the bottomhole zone. According to calculations, this quantity of crude oil should have been sufficient to saturate the bed across its full thickness within a radius of 1.1 m from the well. The electrical heater was then lowered to the well bottom, whereupon injection of casing head gas, used as heat carrier, commenced. A control system was installed to measure periodically both the temperature and the consumption of the casinghead gas being injected. 

In the last section, the conical bottom with a cooling jacket, there are shaft support 5 and rotating perforated distribution grate 6, which at the same tume plays the role of support in case the gas supply abruptly ceases. The radiated heat is withdrawn by a heat exchanger, which circulates through jacket 2. The conical lower part of this reactor is filled with head 8, which prevents contact mass from entering the gas supply line.

Formation water was obtained from producing wells as close to the wellhead as possible, either from the first separator or from the well-head itself. Only the most prolific water-producing wells in each field were sampled. In the case of gas weUs, considering gas production, and temperature and pressure changes during production, less than 5% of the water produced is calculated to be distillate. 

Gas streams for the experimental reactor contained nitrogen, hydrogen, carbon monoxide, sulfur dioxide, and in some cases oxygen, from cylinders, which were blended to synthesize a mixture of reformed natural gas and a sulfur dioxide-bearing gas stream of the desired composition. The composition of this head gas stream was continuously monitored by an on-line process chromatograph. The mixed gas stream was saturated with water vapor at a controlled temperature and pressure to provide a water vapor content consistent with that in actual plant operation. 

N(IV) Nitration of Pyrene. Kinetic runs were conducted with both N(IV) and pyrene as limiting reactants in each case, the runs were conducted in both a standard 10-mm UV cell with a small headspace (—3.2 mL of liquid volume and — 0.5 mL of headspace) and in our vacuum UV cell with a headspace of about 50 mL. In the vacuum UV cell, the head gas was 1 atm of argon. As discussed in the following paragraphs, the order of addition was important, and in the work described here, aliquots of pyrene stock solutions were added to prepared N(IV) solutions. The results from the two different... 

The rate of gas induction is decided by the type of impeller used, the design of the stator, the speed of the impeller, and the static head above the gas ports. Analogous to the venturi loop reactor (Sections 8.6 and 8.7), the rate of gas induction cannot be varied independent of the aforementioned design and operating features. However, in the present case of gas-inducing impeller, in the event that the induced... 

Generally, in the case of gas flow through a catalyst bed, the energy-loss term on the right of Eq. (6.21) is predominant when compared to the geodetic term dx and to the velocity-head term dG. The last term on the right of Eqs. (6.26) and (6.27) is negligible. In each case, consistent measurement units must of course be used. 

The fluid dehvery in an air-spray system can be pressure or suction fed. In a pressure-fed system, the fluid is brought to the atomizer under positive pressure generated with an external pump, a gas pressure over the coating material in a tank, or an elevation head. In a suction system, the annular flow of air around the fluid tip generates sufficient vacuum to aspirate the coating material from a container through a fluid tube and into the air stream. In this case, the paint supply is normally located in a small cup attached to the spray device to keep the elevation differential and frictional pressure drop in the fluid-supply tube small. 

Volume 1 explains that pumps ean be classified as either positive-displacement or kinetie. The same is true for compressors. In a positive displacement compressor the gas is transported from low pressure to high pressure in a device that reduces its volume and thus inereases its pressure. The most common type of positive displacement eompressors are reeiprocating and rotary (serew or vane) just as was the ease for pumps. Kinetic compressors impart a veloeity head to the gas, which is then converted to a pressure head in accordance with Bernoulli s Law as the gas is slowed down to the velocity in the discharge line. Just as was the case with pumps, centrifugal compressors are the only form of kinetic compressor commonly used.
