Depropanizer
The configuration of Depropanizer System is identical to Deethanizer System, having an overhead condenser (E-1107), overhead reflux drum (D-1103) and reboiler (E-1108). The required heat for the reboiler is given by hot oil and for the condenser the required heat is removed by Methanol. The part of the condensed liquid, which contains higher C3 concentration, is fed to the top tray of Depropanizer column as top reflux and the remaining liquid is sent to C3 Product Storage Tank (TK-1402A/B).
The Depropanizer column bottoms, which contains higher C4 concentration is sent to C4 Product Storage Tank (TK-1403A/B) after cooling down to storage temperature of 35°C in C4 Product Cooler (E-1110).
The control system is also same as that

The Demethanizer overhead vapor is passed through Demethanizer Overhead Condenser (E-1101) and partially condensed by heat exchange with feed LNG. Part of the condensed liquid is fed to the top tray of Demethanizer as top reflux and the balance sent to Lean LNG Surge Drum (D-1104) as Lean LNG product. The remaining Demethanizer overhead vapors are compressed by the lean LNG compressor and totally condensed in LNG Preheater (E-1109), as a result of exchanging heat with feed LNG coming from Demethanizer Overhead Condenser (E-1101). This Lean LNG is then sent to Lean LNG Surge Drum (D-1104) and is further dispatched together with the condensate from E-1101 to B.L. using Lean LNG Booster Pumps (P-1105 A,B,C,D) at the required pressure of 100 …show more content…
The number of tanks is two. Liquid butane is pumped to pipeline with the help of pump (P-1403 A/B).
Hot Oil System
Demethanizer, Deethanizer and Depropanizer column reboiler heat is provided by circulating hot oil through reboiler. Hot oil system consists of hot oil storage tank, hot oil expansion drum, hot oil circulation pumps and hot oil heater.
Hot oil is first circulated by Hot Oil Circulation Pumps (P-1301A/B) through Hot Oil Heater (H-1301) where temperature of hot oil rises to 135°C. Low-pressure (LP) fuel gas is used in burners of hot oil heater. The hot oil outlet temperature of H-1301 is controlled by adjusting heater burner firing. From hot oil heater the hot oil is passed through column reboilers, providing the required heat duty and then back to the suction of hot oil circulation pump, thus completing a closed loop. Part of the hot oil from circulation pump is used for C2 Product heating in C2 Product Heater (E-1401).
Any oil drain from hot oil system is first stored in Hot Oil Drain Drum (D-1302) from where it is sent back to Hot Oil Storage Tank (TK-1301) by Hot Oil Drain Pump
This paper has informed you on multiple parts and operations of 7.3 litre injectors. Listing their parts, both internal and external. How the entire system works as one, and how it makes the engine run. Without fuel of some sort the engine would not run. So with this research paper I hope you have learned something.
... If you could provide me with the paragraph, I would be happy to edit it for you. Phase Two of the pipeline is relatively short compared to the rest of the project, as it is only 291 miles long. The main purpose of Phase Two was to route oil from Steele City in Nebraska, through Kansas, and finally down to Cushing, Oklahoma. The construction of the second phase was completed in February 2011.
trapped it beneath the rock. Press/heat changed some of it to coal, oil, and natural gas;
Upon extraction, the crude oil is transferred to a refinery. This is normally done either by pipeline or supertanker ships that are up 1500 feet in ...
After the oil/gas mixture is drawn from the ground, it is then stored into a storage tank and allowed to rest for a while. Then the gas is piped off to a set of distillation columns to clean up the ethane. In order to activate the chemical reaction necessary to separate the ethane, a thermal cracking unit (a sort of long heated tube) i.e. a plug flow reactor is used. After a series of distillations, ethylene exits the tube.
When the hood is open, look in the engine; there should be a metal loop sticking out of a metal cylinder, and that's your dipstick. Pull the dipstick out and with a rag or paper towel, wipe off the end with the oil on it off, put the stick back in, all the way and then pull it out and look where the oil ends on the end of the dipstick. If the oil doesn't reach the inside markings indicated on the end of the stick, you should add one to one-and-a-half quarts of oil, checking the level to be sure you haven't made it too full. If your oil is very dark, thick or chunky, then it is time to change your oil, and it is best to do when the engine is hot.
A condenser and heat reflux was used to prevent reagents from escaping. Then the solid product was vacuum filtered. The product was recrystallized to purify it and the unknown
Surfaces which have been disinfected by this agent may release on irritant vapor for sometime after disinfection and this can be nullified by exposure to NH3 vapor after disinfection.
Possible effects and some examples are pain in stomach, heat stroke, asthma or other allergy symptoms. So this technology is really useful for keeping our homes clean and healthy. The dehumidifier has an incredible design which solves the main issue really well; most dehumidifiers have a fan compressor, reheater, compressing cooler coils, and a reservoir. And here are how these components are broken down into three individual steps to work together and solve the issue. Firstly, a fan from a dehumidifier collects and drags air (with large amounts of moisture) into the machine. Then, as the air is being brought through, it approaches a section of the dehumidifier called the cooled coils. These coils are designed to perform the process of condensation to drag moisture away from the air that is passing through. The moisture would remain on the coils and eventually drip into the dehumidifier reservoir. Finally, the air inside the machine would be reheated and exhausted back to the room.
A heat engine is a method that executes the transformation of thermal energy or the heat to mechanical energy. That mechanical energy can be used as a mechanical work. This work can be manifest by bringing a working material from a high heat condition to a lower heat condition, by that the heat engine will produce calorific power that creates higher temperature conditions of the working substance. After generating a higher temperature state to the working substance a work will be p...
Flash pyrolysis process takes place when heat is increased rapidly in the absence of oxygen and temperature is kept between 450°C- 650°C. within 30-1500 microsecond, condensable and incondensable gases leave the pyrolyzer. After cooling condensable vapors are collected as bio-oil fuel. With rapid increase in heat, liquid yield increases rapidly, results drop in char content. Such operation can maximize bio-oil up to 70%-75% of the pyrolysis product.
The steam engine is a peripheral ignition mechanism, wherein the operating fluids are disconnected from the ignition results. Non-combustion heat resources like nuclear and solar powers or geothermal power could be utilized. Water resorts to vapour in a reservoir and arrive at high pressures. When developed through turbines or pistons, automatic exertion is completed. The condensed-pressure condensation is then compressed, and reverse-pumped to a boiler. Several convenient steam engines remove low-pressure steams rather than compressing it for recycles.
In 2011 PepsiCo announced the launch of their Social Vending System. This system featured a full touch interactive screen. A consumer can select a beverage and enter the reciepent's name, mobile number, and personalized message and gift it with a video. PepsiCo uses technology to their advantage for global implementation.The company uses media sites in multiple was as advertisement and marketing tools.
... temperature of 112 0C also and a pressure 2.5 bar. Cooling water is used to condense the vapor exiting column. Remaining methane and hydrogen are separated in reflux drum where the vapor stream is combined with other gases streams. The overhead of first and second separator are combined to form fuel gas. The liquid stream exiting in the bottoms of the reflux drum is pumped at pressure of 3.3 bar for discharging pressure. The pump stream is separated in two streams. One stream is to feed to tray one of the column and the other one stream is cooled down to 38 0C in heat exchanger. Then, the cooled product stream is sent to storage.
Process da: This low temperature liquid then enters the evaporator where it absorbs heat from the space to be cooled namely the refrigerator and becomes vapour
