Further, the cap includes a panel that has a flat surface bounded by a perimeter that is interconnected to the periphery by an intermediate section. As a result, the cone-shaped member, intermediate section and panel form a fluid chamber. Fluid is positioned in the chamber for movement between a first location where the spray nozzle is submerged and a second location where the fluid is held at a distance from the spray nozzle for removal of the cap from the spray nozzle. | 06-11-2009 |
20100037920 | Method of cleaning and degassing a storage vessel - A sealed storage vessel containing volatile organic vapor over a bottom sludge layer is cleaned by (a) determining the level of free oil in the vessel and then using (b) either a two-stage or one-stage treatment regime, adding a cleaning agent thereto. If the free oil is greater than 2 volume percent the two-stage regime is used where an oil release agent is initially mixed with the sludge to separate the oil from solids in the sludge. The separated oil floats on the surface of water and is removed without substantially exposing the vessel's interior to the atmosphere, leaving within the vessel a mixture of water, solids, and trace amounts of hydrocarbons. Next, a predetermined amount of an emulsifying agent is added to substantially emulsify the trace hydrocarbons, so the level of volatile organic compounds remaining in the interior of the vessel is no greater than 5,000 ppmv, measured as methane, at least one hour after adding the emulsifying agent. If the free oil is less than 2 volume percent, the one-stage treatment regime is employed by only adding the emulsifying agent to achieve this same level of volatile organic compounds. | 02-18-2010 |

The output airflow is diverted from the compressor away from the engine to a disposal or to a means of separating a cleaning fluid from air. After starting the engine and while the engine is running, the cleaning fluid is injected for a sufficient time to clean the compressor. | 06-10-2010 |
20110209730 | Chemical Cleaning Method and System with Steam Injection - Disclosed are methods and apparatus for cleaning heat exchangers and similar vessels by introducing chemical cleaning solutions and/or solvents while maintaining a target temperature range by direct steam injection into the cleaning solution.
