On Site Power Generation for Process Industries

04/08/2013 12:36 PM

What according to you are general considerations for on-site power generation for process industries? What are the things you would consider most relevant for the project?

You go first. What do you think?

This sounds too mudh like a college project.

Some context might help.

This looks like a simple cost/benefits study.

On the surface - Find out what the application is, what they really want (just power or heat as well), the loads involved, location of project, real estate available, packaging constraints, cost of fuel, cost of labor, storage facilities, taxes, federal and environmental regulations in the area and who will operate and maintain facility. The other big question I suppose - how to finance the project : fixed costs, interest rate, inflation, insurance cost, taxes, depreciation costs. What questions would you ask?

Well really your question is an open question because you'll have to consider many aspect to choice the right machine. So any way I will try to recommend some of the more relevalt to be considered:

1- The process engineers shall select the critical load ( equipment, pump, compressor etc)

2- determine how reliable is the greed power supplier, how often the fail occur

3- System voltage level shall be systematic for all the load (if 240, 480)

4- Maximum time allowed by process to start-up the EDG and re-energize the power back without any damage

6- Schedule an start sequency of the equipment to avoid start peak current therefore voltage dip

7- Select the prime mover starting mode whether compressor air or battery system

and other that the rest of member sure can advise to you

Bye

Can you expand on some of the points here and how that would determine the means of power generation? Like for example, point # 4 - how does that determine what you can use? For example, will that say you can't use a diesel generator vs a gas turbine?

You want somebody to perform a feasibility study for you.

Hire a consultant for this exercise, as this is obviously either homework or a for-profit endeaver, so I wouldn't want to leave it up to unqualified strangers to evaluate.

Sorry I misunderstood your question I thunk you talking about EDG, forget my statemant.

Reference to on-site generator it require a complete project desing not proper for this forum

Bye

Check whether you can use wasted energy like steam,heat in cooling water,boiler stack(flue gas) in the factory. Also try running a hydro-generator by rainwater from roof,installing PV in roof,wind mill etc

Dear Mr.bicycledisciple,

You have to spell out a lot.

1. Whether the Power Generation by Boiler-steam-Turbine Route.? If so do you need Turbine Exhaust Steam, and what are the Head Load demand for Process and at What Parameters.?

For Example, Sugar Factory uses residue-known as BAGGASSE, (from cane crushing and extraction of juice, for producing Sugar) as fuel in the Boiler, generate Steam run Turbine and produce Power and use the Exhaust Steam at 1.5 to 2 bar 130 Deg.C for Heating and Boiling the juice, besides meeting out the Power Requirement.

2. If self Generation is proposed and Process steam Demand is not there, you have to condense the Steam for Power Generation, which may nt be viable.

3. You have not described the nature of Process.

The Selection of BOILER CAPACITY, STEAM PRESSURE and Temp. and the POWER DEMAND, TURBINE CAPACITY etc. HAS TO BE MATCHED UP CORRECTLY for ECONOMIC VIABILITY.
