Fill time diesel

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. 

The station should be capable of near automatic, autonomous operation, and require a minimum of local support. Work envisioned at a manual station is to change samples daily, prepare the sample for analysis (like pressing a filter into a disk) and then put it on the detector and push a button. This can be done in less than an hour each time. In areas where line power is unreliable and of bad quality a diesel generator to provide power would, however, probably require more hours for service, fuel filling and maintenance. Full automatic stations have also been designed. 

In the coking step, the feed is heated to approximately 475 to 520°C in an oven with a very low residence time and is discharged into the bottom of a large vessel called, a coke drum for extensive but controlled cracking. The coke drum is not heated. That means that the feed is heated only in the oven. The cracked volatile product rises to the top of the drum and is drawn off. It is then charged to the product fractionator for separation into naphtha, diesel oils, and heavy gas oils for further processing in the catalytic cracking unit. The heavier product remains and, because of the retained heat, cracks ultimately to coke. Once the coke drum is filled with solid coke, it is removed and replaced by another coke drum.

Event A 4 million gallon oil storage tank owned by Ashland Oil Company, Inc., split apart and collapsed at an oil storage facility near the Monongahela River. The tank split while being filled to capacity for the first time after it had been dismantled and moved from an Ohio location and reassembled at the Floreffe facility. The split released diesel oil over the tank s containment dikes, across a parking lot on an adjacent property, and into an uncapped storm drain that emptied directly into the river. ... 

Sensitisation by precipitation at grain boundaries will not necessarily lead to corrosion. This depends on the environment, as shown by experience, even with heat exchangers operating in seawater at temperatures well above 65 °C. Certain diesel tank trucks have been used for over 20 years, filled each day at 65 °C and then operating for 8-10 h this amounts to a cumulated holding time at 65-70 °C for more than 50 000 h.
