Supporting New Energy Techniques

Posted November 27, 2006 10:00 AM

Although the price of gas at the pump has decreased drastically in recent weeks, the impact of high gas prices can still be felt in most chemical companies. Industry trends demonstrate that most organic chemical operations require numerous chemical reactions that often begin with crude oil or natural gas. Even with decreases in overall energy costs, chemical companies are still feeling the financial pinch as a result of these costs. While some companies view energy costs as a natural part of doing business, some are taking the initiative to develop new energy techniques that can save money. What is your organization doing to mitigate high energy costs?

Supporting New Energy Techniques

What is your organization doing to mitigate high energy costs? I have been trying to to explain the concept of Energy Control. I would like to inform a world that is still teaching and using old Technology something different is available involving condensates. The first patented ECC was purchased and has operated sucessfully for over 4 months doing what it was designed to do with no issues recorded. I would like to Explain how this new technology operates with Energy Efficiency as compared to 95 year old Steam Trapping technology that was not designed for effieiency and is still being taught to today in our educational systems. We are willing to work with any company wanting to do a trial on the ECC to prove the Energy Savings and other benifits using this new Condensate Control System.
AUTOMATED CONDENSATE CONTROLLERS

The Concept of Steam Traps,
Steam Traps traditionally have been considered as a "trap" for steam only.
It means that the steam trap had the competence of removing the liquid
condensate as soon as it is accumulated upstream of the trap.
This restricted point of view has firmly been fixed in our mind as a
consequence of the slow evolution of steam traps.
In fact, during decades the Steam Trap has been considered as an on - off
valve unable to control energy, but differentiates between water and steam
(float and inverted bucket traps). The arrival of thermodynamic steam traps
did not change that thinking, but it contributed to waste energy reinforcing the
old idea of "trapping".

Although the Condensate Control Valve (thermostatic steam trap) was
developed to improve and replace the old steam trap idea, most people
associated the on-off operation principal (trap concept) to the thermostatic
steam trap.
Presently, manufacturers and users defend their position according to their
interests; experience or any other reason, without analyzing technically the
consequences of using any of the concepts.
The Modern concept of Energy Control Valves,
Now days the concept of steam trap additionally involves the idea of
controlling the energy discharged through the valve, as well.
Then we should say steam traps when we talk about mechanical or
thermodynamic steam traps reserving a new name, condensate controllers
condensate drain valve systems for example, when we talk about modern
condensate control systems.

Trapping versus Controlling Condensate Energy,
Concepts are easier understood when we analyze global problems (the tree
does allow seeing the forest).

Consider the simplified steam installation. The steam producer (boiler) is
connected to the energy users through the steam distribution lines (high
energy level) and the condensate return system (low energy level).

Trapping steam means creating a physical barrier between the steam zone and
the condensate region (the old "trap concept). The trap discharges
condensate at saturated temperature (maximal remaining energy) producing
flash steam in the return collector. That way, backpressure increases
downstream of the trap and thermal water hammer often occurs. Excess of
remaining energy is lost along the return system or discharged to the
atmosphere at the condensate receiver tank.

Controlling Condensate energy means not only establishing a boundary between
two zones at very different levels of energy, but controlling the transition
between both zones (the condensate "control" valve concept) discharge of
condensate is controlled automatically, Which means that remaining energy is
efficiently to low level temperatures reducing flash steam and water hammer.
Remaining energy often reduces steam consumption by as much as 15% and at
the same time portions of air contamination is reduced, as well.

The trap concept is necessary only in a few applications while controlled
discharge of condensate can be applied on the majority of situations. It
should be clarified that most typical "trapping" examples must be considered
as "controlling" applications.

When Trapping and Controlling Condensate Energy,

Conventionally "trapping" was suggested when we need be sure that no
condensate is upstream of the trap and "controlling" is used when we need to
save energy.

Condensate return systems at large installations (oil refineries,
petrochemical plants, and Pulp and Paper facilities, etc) are very sensitive
to persistent problems caused by back pressure and water hammer. It is
strongly recommended to use the "controlling" condensate energy concept to
prevent these occupancies.

The condensate energy controller's evolution (automated condensate
controllers) makes it difficult to find applications where they cannot be
successfully applied.

Checking "Traps" or "Condensate Energy Controllers"

No matter what type of steam trap is being used it is necessary to establish
a periodically testing program to determine the working condition to ensure
that they are not leaking steam (failed open) or water logged (failed
closed).

To check "Condensate Energy Controllers" we need only to check the pressure
into the controller and the pressure out of the controller.

Hi

Does any one know what happened to the 'magic' powder that could dissolve plastic bags?

Some years back while working for a plastics manufacturer, the owner came back from a plastics show in Germany with this new product. While on the morning tea break he filled a glass with water, then put in a 'pinch' of this powder, put in to the glass a bit of the plastic for making our bags.

With in a few minuets the plastic had completely dissolved, this was before bio-degradable plastics. The plan was to put it into the supermarket bags, as at the time trying to recover the plastic was expensive.

It failed to get approval by the big supermarket chain (SFW) the reported reason that 'the shoppers would not use them for fear of the bags melting in the rain while carrying them the car". What it seems they could not get passed that there was a time lag on how wet it got to it dissolving; this could be extended to the time required by how much powder was put into the plastic mix.

It would seem to be the answer to the plastic bag problem we have now, a bag that costs a fraction of a cent to make, is charged 10cent or there about's as a 'levy,' a good profit move, or did they buy the patent to this powder?

Well, there isn't a single tungsten filament bulb to be seen. Every light source is a high-lumens-per-watt emitter.

Next!
