2.New Technology Description:

Five-ColumnThree-Effect Distillation Process

Our company designs and manufactures latestFive-ColumnThree-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 DistillationProcess

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;itsaves over 40% steam

Q:What is the material of construction used for the heat exchangers in an Ammonia Plant (high pressure and temperature conditions). Is there any useful websites that I can refer to??Thanks for your help,
Construction of heat exchangers, boilers, and surface condenser tubes is mainly limited to copper, steel, stainless steel, and cast iron with exceptions such as the use of titanium in ultra high pressure vessel applications. To assure a proper tube joint, the tube wall must be reduced by a predetermined percentage dependent upon the material the tube is constructed of.[1]. For example, Tubing Material: Copper Cupro Nickel 8 - 10% Steel, Carbon Steel Admiralty Brass 7 - 8% Stainless Steel Titanium 4 - 5% Pneumatic or hydraulic torque rolling devices with an expander (consisting of a mandrel, cage with rolls, case assembly with a thrust collar) are used to expand the end of the tube so it seals against the tube sheet of the vessel. It is important to note that the type of tool has to be with paired not only with material but also the inner and outer dimensions of the tube as well. Thickness of the tube sheet (what each individual tube is inserted into) has to be taken into consideration during tube removal or installation procedures.
Q:I'm thinking of switching to a tankless water heater to do away with my oil burner. I am wondering if I can use a seperate tankless to heat my house.
It may, indeed, be possible, but I'd have to think that a regular gas fired hot water boiler would be much more efficient. Hot water heat has to be circulated constantly and that would make an astronomical gas bill. The heater would run all the while water was flowing through it.
Q:what does the heat exchanger in a vw engine do?
If you are talking about an old air cooled VW, they heat up to give you heat in an old bug or van
Q:I am looking to get this done professionally, but I would be interested to get tips from anyone who has such a system or has set one up. If you send heated water to the oil burner and reduce the amount of work the burner has to do, will it still work? Is there a better way without tearing out my existing heating system?
The link I gave is to help you understand how it works. This is a do it yourself site but having a pro. do it would be a good idea unless you love this kind of thing. The solar system will have its own loop with antifreeze and a heat exchanger will allow it to add heat to your current boiler system. This will reduce the amount of energy that has to come from the oil. You are in a good position for this since you already have the hot water base board heat. ***** Sorry that link is not very good since it was just for hot water heaters.
Q:I have a liquid stream entering at 40 degrees and is to be heated to 500, where the liquid changes to gas. Would it make more sense to use a fired heater or a shell and tube heat exchanger?Many thanks in advance.
It really depends on what heat sources are available but with a 500 degree requirement, a fired heater could be a good solution unless you have access to very high pressure steam as an alternative. Most heat medium systems are limited to about 450 to 500 degrees and that would not be sufficient for your requirements.l
Q:The thermostat wires hooked to the unit is a five wire plug in type but someone changed the thermostat and it has places for many more wires. They removed the plug and connect to wires together. The cooling mode works just fine. Do I need to get a 5 wire thermostat? My heat pump is a Friedrich Vert-I-Pak model vha18k50rtd.
You will also need the wiring diagram of the thermostat (available on line from it's manufacturer). These instructions are simple and easy to verify that your thermostat is compatible, and wired correctly. You haven't stated who changed the thermostat, or why. You might want to begin by answering these questions.
Q:GOODMAN H A-18 YRS. OLD HAS CRACK IN HEATING EXCHANGE. CAN I REPLACE IT FOR LESS THAN $1,000 ?
If you can do it yourself, will be only the cost of the part: $75.00 to $100.00. If you call one of those money hungry Heating Contractors, it can be as much as that $1000.00. In fact an 18 years old furnace you will be better off replacing the whole thing with a new energy efficient unit. Good luck...!
Q:around the house?
I okorder / Hope this has been of some help. Regards, Trevor From Canada
Q:how works a heating pump?
A heat pump works just like a refrigerator. It moves heat from one sure to another, using the compression and expansion of gases to do the work. The heat pump operation is different from that of a refrigerator, in that it can move heat in two directions. Compressing a gas to a liquid makes it hot. Vaporizing a liquid cools it. To heat the house, the heat pump compresses gas, and a heat exchanger cools the resulting liquid. The liquid is pumped to the outside of the house, where it is expanded. Outside air heats the expanded gas, which is then returned to the house. To cool the house, the process is reversed.
Q:which cooling fluid is available for this processc?
As long as pressures are low, flat plate heat exchangers are cheapest to construct. If pressures are above 1 atm by much plate and tube is the next cheapest. Cooling fluids are either R-12 or its replacement (R-134a?) and ammonia (if food is involved) . Ammonia probably is cheapest and best refrigerant for industrial use. Other refrigerants at this temp are CO2 and propane
