2.New Technology Description:
Five-ColumnThree-Effect Distillation Process
Our company designs and manufactures latest Five-Column Three-Effect Distillation equipment.This new process is promoted on the basisof traditional five-column differential-pressure column and mainly used forsuper-fine alcohol production.
The key of this process is the heatingmethods,the steam heats one column directly andtransfers theheat to other 4 columnsto achieve three-effect thermal couplingand energy-saving effects.
In terms of electricityefficiency, it can save 50% electricity and avoid the repairing ofcirculating pumps and also extend the working life of there-boilers.

Double-Mash-Column Three-Effect Distillation Process
This process applies to the production ofgeneral-grade alcohol& fuel ethanol, and it was awarded Chinese nationalpatent, it is the onlysuccessfulapplicationof doublemash column & three-effect in the world,whichproduces general-grade alcohol.
This process is composed by mash column,rectification column and composite column. The composite column functions asmash column and rectification column.
The key of this process is the heatingmethods: the steam heats one column directly andtransfers the heat to other 2 columns to achieve three-effect thermal couplingand energy-saving effects.
The advantage of this process is energy-saving;it saves over 40% steam

- Q: What is the difference between a Pressure Vessel and a Heat Exchanger?
- Well!!! Both are not so close to be differentiated.. A pressure vessel is a closed container designed to hold gases or liquids at a pressure different from the ambient pressure. The Pressure may vary from 1.1 bar (a) to 5000 bar (a) [in some cases!!]. A common design is a cylinder with hemispherical end caps called heads. Pressure vessels are used in a variety of applications like road vehicle airbrake reservoir and storage vessels for liquified gases such as ammonia, chlorine, propane, butane and LPG. On the other hand,... A Heat Exchanger is a device built for efficient heat transfer from one medium to another, whether the media are separated by a solid wall so that they never mix, or the media are in direct contact. One common example of a heat exchanger is the radiator in a car, in which the heat source, being a hot engine-cooling fluid, water, transfers heat to air flowing through the radiator [i.e. the heat transfer medium]. They are widely used in refrigeration, air conditioning, power plants,etc.
- Q: Trane unit Electric
- That's a good brand. Probably the reason is the duct work has to heat up also and it will take a few minutes for it to become as warm as the air coming through it.
- Q: We want to heat the high pressure hydrogen gas up to 150 degree centigrade in a heat exchanger by using available thermic fluid of sytherm oil T-55
- Charles Law states: That the volume of a fixed mass of gas held at a constant pressure varies directly with the absolute temperature. If you increase temperature you'll increase pressure.......
- Q: The sump is about 1000 gal the flow through the heat exchanger is about 4 gpm
- What is the heat exchanger inlet/outlet temp, flow of coolant and type.
- Q: I have quotes for replacement of A/C and Furnace, prices include tax and installation. All motors have variable speedFurnace:Rheem-Prestige Series 90, model RGFD 92%. with lifetime heat exchanger unit replacement warranty, 10 years on labor and parts, 90,000 BTU: $4200Lennox-G61V 94.3%, 90,000 BTU, lifetime warranty of heat exchanger, 10 year parts, 2 year labor: $3850Carrier-Infinity 96.6%, 100,000 BTU, lifetime warranty of heat exchanger, 5 year parts and labor: $4000A/C (3 tons)Amana-ASX14, 14 seer, 10 year part labor warranty, lifetime unit replacement on compressor: $3450Lennox-Elite Series XC14, 14 seer. 5 year part, 2 year labor and 10 year compressor warranty: $3150Carrier-comfort series, 14 seer. 5 year part and labor warranty, 10 year compressor warranty: $3500Which ones are the best choices of A/Cs and furnaces with the price and warranty that they offer. Thank you for your advices!!
- i am a 30 year vet in this feild. go with the rheem best warrenty best performance and energy eff it will last you 20 years.
- Q: can someoen explain to me the effect or the meaning of U in heat exchangers? im using a cocurrent and countercurrent flow device. and i cant figure out whether the U is supposed to be different depending on the flow of the device. im assuming U is like a resistance, so the greater the value of U the more resistance, and the less heat transfer that occursthanks
- the standard formula for thermal transfer using U(thermal coefficient) is Q=Au ( T1 - T2) Q is the absorption of heat in btu T1 is the temp differential internal T2 is the temp differential external A is the area of the material as an example lets do a problem Q= 200in sq (.19) (22degrees)=836 Q=200 in sq (.30) (22degrees)=1320 as you can see from the ex's that the higher the thermal transfer the greater the btu absorption. Respectfully the reverse or rather the loss of btu is the same. If you have a piece that is in operation measure the temp differential use a selected surface area and you can estimate the U value or you can look in the ASHREA manuals for a really long list. Since you mentioned it the relationship of U-value to the resistance is a relative matter the higher the number the greater the transfer,inversely 1/U = the R value which by practical example is more like the resistance to transfer....Well I hope I got in there somwhere with some help...Have a good one from the E
- Q: do solar panels work with light particles or heat waves?
- there are different types of solar panels: the type made up of electrical solar cells converts LIGHT energy to electric energy the type made of a heat exchanger converts infra-red light energy (heat waves) from the sun into a heated fluid that then is used to heat buildings.
- Q: My furance runs, but the Firebox is damaged with Rust. Furance company told me to get a new one. The furnace runs but I am not using it. Can the box be replaced? and Who would do such a repair if it's possible. Unit is from 95, and has an energy star label on it. Unit is only used for Heat, not hot water.
- If this is a forced air furnace; I'll tell you a secret .....Furnace heat exchanger is probably still under warranty. Problem is that its a major job to replace because most of the time the furnace has to be pulled, completely disassembled, and then put back in place. The contractor is going to make his money either way and its going to be most of the cost of a new one anyway when you take all things into consideration. You will spend all that money and still have a 12 year old piece of equipment that has no warranty on any parts other than the heat exchanger. When you consider that a call to repair any other part is going to be several hundred by the time its done, sometimes its just good economics to replace it when you can buy a standard furnace that has a 10 year warranty on everything and just be done with the problem.
- Q: Are there any differences is performance letting the hot fluid flow thru the inner pipe and the cold fluid thru the annulus and vice versa??
- they're an economic determination for small exchangers that would desire to easily require some accepted tubes. they're additionally a sturdy determination for smaller intense tension applications. the alternative is often one in keeping with economics. there is not any rule that determines the determination technique.
- Q: If any body knows about a solar panel which can perform both the operation in a single panel i.e heating up the water as well as charging the batteries for electricity in a single panel. Please describe me about that and let me know where to look for it.
- Every once in a while, someone tries to do this, but the general problem is that you want the panel as cool as possible for electricity, and as hot as possible for water. Thus, I don't know of any commercial products that do what you ask. If you want hot water and electricity, the standard thing is to install two different kinds of panels, with preference to the location of the electric panels, as they are more sensitive to shading.
