Fill time station

There are two ways of refueling compressed natural gas (CNG) time-fill or fast-fill. For a time-fill compressor, it is necessai y to develop a pressure only slightly greater than the vehicle storage pressure—the gas flows from greater pressure to less pressure. Time-fill compressor stations can require a couple of hours to refuel, which is a major inconvenience for most motorists. However, it is the best choice for many fleets that can he refueled overnight with one fill-post for each vehicle to be refueled. 

The foaming of diesel fuel has drawn a certain attention in the last decade. Antifoams are usually one component of a package of diesel additive, which is used to adjust and improve the properties of the distillate from the refinery [44]. Antifoams prevent foam formation of the treated diesel fuel during pumping at refineries and service stations at treat rates between 5 and 15 ppm. They help to shorten substantially the filling time of fuel tanks and avoid splashing over. 

Current research on fuel cells is directed toward the replacement of the internal combustion engine. To do this, hydrogen must be stored in the vehicle and replenished from time to time at filling stations. Three kilograms of hydrogen should be enough to drive a small car 500 km (300 miles) between fill-ups. 

Fig. 2 Time-series of annual mean water temperature in the San Reservoir (Spain) and air temperature in the Ter River watershed. The series start in 1964, after the first filling of the reservoir. Annual means are based on monthly measures of the volume weighted mean temperature. Only years with at least 10 temperature profiles were included in the figure. The air temperatures are annual means for the whole Ter River watershed, calculated from data collected in several meteorological stations in the basin, and weighted according to their area of influence...

Multiple arm machines rotate molds into the different stations of the process. A three-arm machine would, for example, have one mold filling while another is heating in the oven and the third cooling in preparation of demolding. This is very efficient but requires that each stage takes the same time to accomplish. When there are three different parts, the largest part or the one with the thickest walls defines the speed for the entire process. 

The major effort for the Pine Bluff Arsenal development work was concentrated on the filling system with other work stations receiving as much attention as time and funding allowed. The facility is listed as WP Line No. 3, Building 34-110, at Pine Bluff Arsenal. A partial listing of major material and equipment requirements and components for the facility is as follows ... 

The larger, heavier fuel tank that is used has a limited range of about 100 miles. Refilling takes two to three times longer than refilling from a gasoline pump. Some slow fill stations can take several hours and the limited availability of filling stations can be a problem. 

Various combinations of applications, including different choices of photovoltaic panels and electrolysers were tested. The cumulative operating times logged for the various plant subsystems differed considerably according to the test programs run, ranging from 6000 h for the alkaline low-pressure electrolyser, to 2000 h for the membrane electrolyser, 5200 h for the catalytic heater, 3900 h for the PAFC fuel cell plant and 900 h for the LH2 filling station.

On a rotary press the filling of the die and the following compression process is done at the same time at different stations. The compression is carried out in the simplest case with two rolls touching the upper and lower punches and compressing the powder mixture. In contrast to the eccentric press, the upper and lower punches exert pressure on the tablet mixture from both sides at the same time.
