    on quickly increase in recent year, consumption of finished oil increase al well, the va fuel dispenser por pollution and resource waste in forecourt become more important safety factor in considerable filing station, safety distance and vapor density in particular. At present, vapor separator device is installed and obtain content effect in most of large and middle cities reference to foreign improving measures. Its recovery principle is divided as two phases: first phase refers to closed discharge from tank vehicle; second phase refers to vapor recovery as refueling oil. Phase I vapor-recovery system The first phase system aims at to rebuild the delivery pipe and vapor recovery pipe between vehicle tank and tank. (Diagram 4-1) The volume of vapor will be increased as flowing into tank because of waves and shock. Therefore, the inlet pipe should be deeply stretched under oil level so as to reduce oil waves. As for a tank exceeding 945L of volume, inlet pipe is needed stretching into oil no higher 15cm than bottom of tank. Oil flows into tank from under level, vapor flow back into vehicle tank under pressure. In principle, the volume of oil and vapor is fuel dispenser corrective. In order to make as little as vapor volatize during delivery, the structure of traditional ventilating pipe should be improved, making system in sealed state under normal pressure range. Reclaimed vapor is dealt with through condensation, adsorption and burn after taking back. Its operation principle is similar to the vapor system of balanced nozzle. Diagram 4-1: Phase I Vapor Recovery System The pipeline installation is illustrating fuel dispenser in Diagram 4-2. The height of air pipe at least 4m. The length of back air is shorter than air pipe, diameter larger than that of air pipe. It is prohibited to appear overflow phenomenon as vehicle tank discharge, shut off switch of air pipe. The jointer between air back and discharge pipe should adopt speed jointer. Phase II vapor-recovery system Phase II refers to the progress in which vapor in vehicle tank is

    ittle-understood CFIUS reviews, so that politicians are now more comfortable with the c fuel dispenser ommittee s advice. Many foreign would-be buyers of American firms remain sceptical, however, attributing the recent muted reaction in Congress to the fact that the politicians are having more fun slamming the president for failing to control soaring fuel prices. Coming after Congressional concerns over the sale to overseas buyers of Global Crossing, a telecoms firm, and to the would-be purchase of Unocal, an oil company, by the China National Offshore Oil Company, many foreign firms have interpreted the blocking of the Dubai Ports deal as proof of American hostility to foreigners buying its companies. Phillip Swagel, of the conservative American Enterprise Institute, thinks that such gloom is overdone, however. Those three Congressional outbursts were each special cases, not a trend, he says. As long as foreign buyers work closely with Congress, and sell the deal effectively, future forays will get the go-ahead, he says—although he thinks Chinese buyers might do well to make any acquisitions in partnership with a British or Dutch firm, who fuel dispenser se presence might reassure Congress. “Hopefully, the latest Dubai deal will demonstrate that Congress isn t going to shoot down every foreign acquisition,?he says. Well, maybe. But wait till the next big firm from, say, Dubai or China comes a-calling with a fistful of dollars. © 2006 .
