Other addition reactions of aldehydes oeeur. Water, for example, adds to the earbonyl of trichloroacetaldehyde to form chloral hydrate, a strong hypnotic and sedative known as knock-out drops or (when mixed with alcohol) a Mickey Finn. Complete the reaction by drawing the structural formula of chloral hydrate ... 

Trays knocked out and in bottom of tower. Poor stripping. Low pressure drop that was 2/3 of expected. Six of 18 trays were knocked out. Scan proved problem. Operational problem. 

The maximum simultaneous load in each header must be calculated separately and the pressure drop must also be computed for the entire length of the pipe including the combined length from the knock-out drum to the stack. 

Example The maximum flare load of a system is 1,000,000 Ibs/hr of vapor. The pressure at the base of the flare stack is 2 psig, the average molecular weight of the vapor is 50, at a temperature of 200°F at the combined header to the flare stack. The distance from the drum to the stack is 500 ft. The line consists of two 90° welding elbows and an orifice for a flow controller. The total pressure drop at the knock-out drum is 0.5 psi. Determine the pressure at the inlet of the knock-out drum. 

Knock-out drums, used when the hquid content of the incoming stream is low, is a special case of a gas-hquid separator. The drum is placed before a compressor inlet to prevent hquid drops fi om entering and damaging the compressor. In this case, allowing a sufficient residence time for the hquid is not a consideration. 

Toyota practiced 100% JIT supply system with a sole source brake supplier. A major fire in February 1997 destroyed the brake plant and disrupted the production in 20 Toyota assembly plants worldwide costing 1.8 billion in lost sales. A 17-day strike in March 1996 at the Delphi brake plant in Dayton, Ohio shut down 26 GM s North American assembly plants and it cost nearly 1 billion to the company s first quarter earnings (Fitzgerald, 1996). The earthquake that struck Taiwan on September 21, 1999 knocked out the production of memory chips, circuit boards, and other components. It impacted 50% of the world s supplies to major computer manufacturers and their earnings dropped by 5%. Investors reacted more negatively to "Pull-type" supply chains (Dell, Gateway) as opposed to Push-t5qje" supply chains (IBM and Compaq). 

Gravity separators Separation of gas from liquid by allowing sufficient time for (a) droplets of liquid to fall out of gas, and (b) bubbles of gas to rise through liquid Gas-oil separators (CS4). Knock-out vessels in front of compressors the fuel gas for gas turbines must be free of liquid droplets and these drop out in Knock-out vessels which are described later... 

On the other hand, when the demand is constant, the market price increases with a drop in supply. If an extraordinary event, such as a hurricane, were to knock out some oil supply in the Gulf of Mexico, then oil prices would increase rapidly. (In fact, even the anticipation of a shortage would cause the price of oil to rise). With a higher price of oil, there is even more motivation for the oil producers to repair and restore lost oil supply. 

There are two main assumptions for the establishment of the model all the particles moving in suspension above the strand are at the velocity of the air all the particles moving in the strand are at the velocity of air in the strand. There is a steady-state particle exchange between the suspension flow and the strand. The suspended particles impinging the strand will slow down to the strand velocity and be expelled from the suspension. Other particles will be knocked out from the strand and accelerated by the air to the same velocity of the air in the suspension. Based on Fig. 4, the force, mass and momentum balances are set up accordingly. The pressure drop is subdivided initially into additional pressure drop and singlephase air pressure drop ...
