Water injection systems temperature

A patented water injection system has been devised for extinguishing oil and gas well fires in case of a blowout. The "Blowout Suppression System" (BOSS) consist of finely atomized water injected to the fluid stream of a gas and oil mixture before it exits a release point. The added water lowers the flame temperature and flame velocities thereby reducing the flame stability. In the case where the flame cannot be completely dissipated, the fire intensity is noticeably deceased, preserving structural integrity and allowing manual intervention activities. A precaution in the use of such a device is that, if a gas release fire is suppressed but the flow is not immediately isolated, a gas cloud may develop and exploded that would be more destructive that the pre-existing fire condition. 

You may need to use bigger jets in your carburetor or an add-on water injection system to increase the amount of water to the cylinders for better performance. And a couple winds of copper tubing around the exhaust pipe from the fuel (water) pump would raise the water temperature for better vaporization too. 

Downstream of the ATR, the reformate was cooled in HX-A, further cooled and enriched with water by the water-injection system WI-1 and then entered the high temperature water-gas shift reactor (HTWGS). About 750 W of energy were removed from the reactor by internal heat-exchange. This made isothermal operation at 390 °C possible. 

When the ejector system consists of one or more ejectors and intercondensers in series, the volume as pounds per hour of mixture to each succeeding stage must be evaluated at conditions existing at its suction. Thus, the second stage unit after a first stage barometric intercondenser, handles all of the non-condensables of the system plus the released air from the water injected into the intercondenser, plus any condensable vapors not condensed in the condenser at its temperature and pressure. Normally the condensable material tvill be removed at this point. If the intercondenser is a surface unit, there wall not be any air released to the system from the cooling w ater. 

There is much concern about the emissions which result when fuel sulfur combusts (i.e., sulfur oxides). These gaseous products further react to form environmental pollutants such as sulfuric acid and metal sulfates. Active sulfur and certain sulfur compounds can corrode injection systems and contribute to combustion chamber deposits. Under low-temperature operating conditions, moisture can condense within the engine. Sulfur compounds can then combine with water to form corrosive acidic compounds. 

A more flexible arrangement is to use a single circuit with pressurized water and steam injection into this circulation (Figure 9.7). Such a system can achieve temperatures up to 200 °C with 16 bar of steam. When cooling is required, the steam injection is shut off and cold water injected into the circuit. An expansion vessel separates steam from water and maintains a constant water level in the... 

Accurate self-consistent thermochemical data for the copper chlorides up to 200°C are required, in order to improve solubility calculations and electrochemical modelling capabilities for Aspen Plus and OLI software. Experimental work has been initiated at the University of Guelph, Canada and UOIT to determine a comprehensive thermochemical database, for solubility limits of OMIT, and aqueous cupric chloride versus chloride concentration and temperature using UV-VIS spectroscopy (Suppiah, 2008). The chloride ion is obtained by adding LiCl OMIT. The conditions of tests are primarily 25-200°C, up to 20 bars. Specialised equipment for this task is needed to reach elevated temperatures and pressures, because cupric chloride is chemically aggressive, and because changes in the solution concentrations must be made precisely. A titanium test cell has been custom made, including a UV-VIS spectrometer with sapphire windows, HPLC pumps and an automated injection system. The data acquired will be combined with past literature data for the cuprous chloride system to develop a self-consistent database for the copper (I) and copper (II) chloride-water systems. 

DTFS, and CMHF. Bench scale and DTFS tests were performed on all three fuels, while the CMHF tests were performed only on the CSD and PFD SRC fuels. The low melting temperatures of the SRC resulted in pluggage of both DTFS and CMHF fuel injection systems. Special water cooled fuel injectors were fabricated to alleviate this problem. 

The mixture requires a certain water content in order to fall on the curves shown in figures 5.1 and 5.2. If the water content is reduced below this level, then the hydrate temperature, at a given pressure, is reduced. Reducing the water content is a common method for combating hydrate formation in acid gas injection systems. 

Using small quantities of additives, such as cerium oxide, incorporated in the fuel or injected into the exhaust ahead of the particulate trap. The additive, when collected on the filter with the particulate, allows the particulate to bum at normal exhaust temperatures to form carbon dioxide and water. This system is insensitive to sulphur and can be used with current European diesel fuel containing 500 PPM of sulphur.

Determination of pyrogallol. Pyrogallol was assayed by HRP catalyzed imidazole chemiluminescence coupled to the micro-flow injection system at room temperature. Pyrogallol specimens (50 pL) were injected using an autosampler (AS-950, JASCO, Tokyo, Japan) every five min into a stream of water (100 uL/min) using a HPLC pump (PU-980, JASCO), and the other mobile phase (imidazole 100 mmol/L in the Tricine buffer 50 mmol/L, pH 9.3) was delivered at 100 pL/min. The light emitted from the reactor tube was detected with a... 

In pipe systems on the platform, the most severe corrosion attacks have been found between the wellhead and the first-stage separator, where water is precipitated, and where pressure, temperature as well as flow velocity are highest [8.29]. To a great extent, the attacks are localized in and at welds, in pipe joints, bends, and at places with reduced pipe diameter. (In many cases the attacks at welds could have been avoided by proper selection of welding consumables.) When the water content exceeds a critical level, the attacks become more severe. This is probably the reason for increased corrosion when the producing wells get older (the content of water increases with time due to water injection).
