Rails

When process tanks, road tankers, or rail tank cars are filled, material in the vapor space is forced out of the tank and lost to atmosphere.

Sales gas would be piped directly into the national gas distribution network (assuming one exists) and NGL products such as propane and butane can be stored locally in pressurised tanks. NGL products are often distributed by road or rail directly from the gathering station, although if ethane is recovered it is normally delivered by pipeline. 

The effectiveness of the approach is demonstrated on two rqjresentative NDT techniques intapretation of data acquired with an ultrasonic rail inspection system and interpretation of eddy-current data from heat exchangers in (petro-)chemical industry. The results show that it is possible to provide a high level of automation in combination with efficient operator support for highly variable NDT measurements where up to now use of automated interpretation was only limited. 

Homogeneity of data. Homogeneous data will be uniform in structure and composition, usually possible to describe with a fixed number of parameters. Homogeneous data is encountered in simple NDT inspection, e.g. quality control in production. Inhomogeneous data will contain various combinations of indications from construction elements, defects and noise sources. An example of inhomogenous data are ultrasonic B-scan images as described in [Hopgood, 1993] or as encountered in the ultrasonic rail-inspection system described later in this paper. 

A mechanics-free airborne sound location system is used in order to record the probe movement and the rotation direction of the probe relative to the weld. Two airborne sound transmitters are arranged on the probe holder and two receivers are fixed on a 50 cm long rail equipped with two magnetic pads The exact probe position and rotation direction is continuously determined by system. 

The procedure approved by Gosstandart may have status of state standard, for example, GOST Non-destructive Testing. Ultrasonic Testing of rails , where types of devices, probes, procedure of the instrument adjustment are specified. Such kind of procedure may be used on site.

The United States wet millers buy ca 15% of the com used in the U.S. (worldwide, wet millers consume about 10% of the com used). There are two dozen com wet mills in the United States ranging in capacity from 600—10,000 metric tons/day. SheHed com is shipped to wet millers by tmck, rail, or barge. 

Acrylonitrile is transported by rail car, barge, and pipeline. Department of Transportation (DOT) regulations require labeling acrylonitrile as a flammable Hquid and poison. Transport is regulated under DOT 49 CFR 172.101. Bill of lading description is Acrylonitrile, Flammable Liquid, Poison B, UN 1093 RQ. ... 

ICIFM-21SP Monopolar Electrolyzers. Id s EM-21 SP monopolar electrolyzer incorporates stamped electrodes that are 2 mm thick and of a relatively small (0.2 m ) size (50). The electrolyte compartments are created by molded gaskets between two of the electrode plates the electrode spacing is finite and is estabHshed by gasket thickness. The electrode frames are supported from rails and are compressed between one fixed and one floating end plate by tie rods. Inlet and outlet streams are handled by internal manifolds. A crosscut view of the electrolyzer is shown in Eigure 21. As of 1989, ICI had Hcensed 20 plants having an annual capacity of 468,250 t of NaOH. 

Anhydrous ammonia is moved worldwide ia specially designed vessels, barges, rail cars, and tmcks. AH modes are covered by rigid safety restrictions (8). Ships and barges usuaHy employ refrigeration or semirefrigeration to maintain the Hquid, while rail cars and tmcks normally depend only on pressure... 

Historically, internal scrapers or paddles were used in some designs, and loose rails were used in others to break up any caking material which formed. The nature of these designs mechanically limited the furnaces to relatively small sizes producing about 3000 t/yr. High maintenance costs were also involved. 

Off-gases (top gas) leave the top of the furnace through uptake pipes, reverse direction ia the downcomer, and enter the dust catcher, ia which condensed water and dust are separated from the gases. The wet dust is emptied iato a rail car for transport to a siater plant for recycle or to a landfill.

Transportation. For short distances from the mine, transportation (qv) is by tmck or conveyor belt. Rail transportation is generally used for greater distances. Slurry pipelines (qv) ate being considered as an alternative. Rail transport over hundreds of kilometers results in loss of surface material in uncovered cats and a tendency to overheat in bottom-dumping tail cats owing to air infiltration around the cracks (31). Proper sealing and covets permit shipping over hundreds of kilometers. 

Thermal drying has been studied in conjunction with a rail shipment of ca 1200 km from North Dakota to Illinois. Oil was appHed at 6-8 L/t to suppress dust loss, and cracks around the doors in the base of the cat were sealed to prevent ignition. Stable shipment and stockpiling were then possible (31). Thermal drying may be carried out to further reduce the moisture content as requited for briquetting or for mote efficient pulverizing and combustion. 

ButyUithium is available in hydrocarbon media, eg, hexane, heptane, cyclohexane, and toluene in several concentrations, eg, 15, 25, and 90 wt %. It is shipped commercially in 10-, 19-, 106-, 216-, and 454-L cylinders and 1900-L (500-gal) tanks and in bulk in 19,000-L (5,000-gal) tank tmcks and 30,300-L (8,000-gal) rail tank cars. For shipment purposes, / -butyUithium is described as a pyrophoric fuel and is classified as a flammable Hquid. As such, full precautions should be taken according to handling instmctions (100). 

Molten maleic anhydride is shipped in tank rail cars, tank tmcks, and isotanks (for overseas shipments). Tank rail cars are typically constmcted of lined carbon steel and are insulated and equipped with steam coHs. Tank rail cars containing as much as 80 m (20,000 gal) are used. Tank tmcks are typically constmcted of stainless steel [12597-68-1/, insulated, and equipped with steam coHs. Tank tmcks containing up to 17 m (4500 gal) are used. Isotanks are typically constmcted of stainless steel and are insulated and equipped with steam coHs. Isotanks containing up to 17 m are used. 

Mica is shipped by tmck (20.4 t max) or railroad (27.2 t max). Bulk tmckloads and rail shipments, such as palletizing, bagging, and shrink- or stretch-wrappiag, are made to avoid extra costs. Mica is usually palletized and shrink- or stretch-wrapped for shipment. 

Dry soHds, such as as-rnined ore, emshed ore, and dried concentrates, are transported using tmeks, rail cars, ore passes, conveyor belts (see Conveying), or slurry pipelines (qv) as dictated by the logistics, distances involved, and capacity. Within the mill, conveyor belts are more common, but for fine particles, tailings, and coal, slurry transportation is more typical. 

Large quantities of pelletized HDPE are shipped by rail in hopper cars with a capacity of 80—100 t. Smaller orders are distributed in cormgated cardboard boxes (1.0 X 1.2 x 0.9 m) with a capacity of 450—500 kg of resin. 

MultiwaU. shipping sacks are suitable for transport in aU kinds of carriers from tmcks to seafaring vessels. Particular care must be taken to prevent the storage of objects with sharp projections adjacent to the bags in case of doubt, it is advisable to line the enclosure with kraft paper of a basis weight >23 kg. Additional rules for the transportation of multiwaU sacks are contained in appHcable tariff specifications and should be consulted for rail, tmck, and ocean-going shipments. 

Storage and shipment are preferably molten. Insulated and heated tanks are used, as are insulated rail tank cars and tank tmcks. In the United States, rail tank cars can hold about 84 t, and tmcks about 20 t. The molten form can be handled and pumped in bulk form, and as a result is priced lower than the sohd. Sohd phthahc anhydride is available as flake in 1-t and 0.5-t super sacks, and 22.7-kg multiwall bags.
