Pipe lean

Pipe lean The angle between the vertical and a typical stand of pipie with the setback. Racking platform A platform located at a distance above the working floor for laterally supporting the upper end of racked pipe. 

When MEA is used in the presence of COS and CS2, they react to form heat-stable salts. Therefore, MEA systems usually include a reclaimer, The reclaimer is a kettle-type reboiler operating on a small side stream of lean solution. The temperature in the reclaimer is maintained such that the water and MEA boil to the overhead and are piped back to the stripper. The heat-stable salts remain in the reclaimer until the reclaimer is full. Then the reclaimer is shut-in and dumped to a waste disposal. Thus, the impurities are removed but the MEA bonded to the salts is also lost.

With Sherlock Holmes and Sir Boss impatiently waiting. Dr. Watson casually leaned against the vat, slowly and carefully filled his pipe, and— with the keen sense of the dramatic—lit it. There our story ends. 

The most popular use of CSZ is as a gas sensor (2 sensor) for automotive exhaust, the structure of which is shown in Fig. 3.2. The sensor with the standard electrode (air) is inserted in exhaust pipes. The relation between the ratio of air to fuel (RAF) and the EMF is depicted in Fig. 3.3. The EMF shows a sharp drop at RAF = 15 (equivalent composition), left of which is called the rich burn region and right of which is called the lean burn region. Because the bad gases, such as CO and NO , , in exhausted gas are minimized at the point of equivalent composition, the value of RAF is controlled by the feedback of EMF. 

As Harry and Rod walked toward their high school, Harry seemed out of sorts. Want to smoke a bowl before class he asked. Rod smiled and nodded. The boys ducked into an alley next to a dry cleaner about a block from school. Harry pulled a wooden pipe out of his back pocket, and Rod shook his head, You are takin chances, man Anyone could of seen that in your pocket there Harry smirked and pulled a lighter out of his backpack. He packed the bowl with pot and handed the pipe to Rod. After a few hits, Rod exhaled loudly and leaned against the brick-faced building. 

In yet another analysis, Swain found plastic pipes to be about twice as permeable to hydrogen as to natural gas. Even so, the risks were still negligibly small from a safety standpoint. Swain also found that lean hydrogen flames are not visible in the presence of other light sources, but rich hydrogen flames are quite visible, and that the addition of small quantities of gaseous hydrocarbons increases the flame visibility of hydrogen substantially. ... 

Someone slows down and is hit by a faster-moving car from behind. The first crash produces a pile of stopped, wrecked cars. This pile then enlarges in the upstream direction jas more and more cars pile into the stopped wreckage.) The rate of propagation of the boundary between stopped and moving fluid (assuming rigid pipe walls) is the local speed of sound. That is not proved here, but may seem clearer after we have discussed the speed of sound in Chap. 8. From Chap. 8 we lean borrow the fact that for water the speed of sound is about c = 5000 ft/s j(1520 m/s), so that the stopped layer of water will reach the reservoir in r =L/c = (3000 m)/(1520 m/s), or about 2 s after the valve is closed.

A blue tinge in the lean amine indicates the presence of cyanides. The cyanides are coming from the FCCU wet gas. They should have been scrubbed out of the wet gas with an aqueous-phase polysulfide wash. These cyanides will promote corrosive failures in amine regenerator overhead system and hydrogen blistering or cracking in piping and vessels that contact the lean amine. 

The signal of the lambda probe in the exhaust pipe is fed into an electronic control circuit which keeps the actual lambda value close to 1, i.e. so that nearly complete combustion is achieved. The fuel-air composition under these conditions is a rich rather than a lean mixture. The exhaust gas then contains CO, NO and residues of hydrocarbons. These components are converted by means of the three-way catalytic converter into the less harmful gases N2, H2O and CO2. If the lambda value is higher or lower than the optimum, then the poisonous gases canot be converted properly. The optimum APR is ca. 14.7, i.e. 14.7kg of air are needed to burn 1kg of fuel.
