Defining a base component for a kinetic reaction in PRO/II

Basically the BASE component has three functions:

(1) The basis for the specification of reaction conversion.
(2) Report conversion in the output report. Only the conversion of BASE component will be calculated and reported in output, in addition to the regular information-- feed, change, and product rates.
(3) User added kinetics

From Peak Oil: How Much Recoverable Oil Do We Have?

"Oil’s availability is of course of immediate concern to every driver, especially at a time when gasoline prices are high once again. The much greater concern, however, is whether we are reaching a limit where oil can no longer be recovered at prices consumers are willing to pay.

If something like that turns out to be true—a scenario that generally goes by the name of “peak oil”—then long-term economic growth may be constrained across the industrial world. At the same time, to look at the brighter side of the picture, long-term carbon emissions may be lower than previously projected."

Read the full article here.

Two points that I found interesting: 

  1. "The Age of Unconventional Oil and Gas" I agree with this point - we are at a point where recovering and processing unconventional oil & gas will be important if want to continue to use oil as a fuel. 
  2. "In effect, they suggest, [oil] prices have reached a level where consumers seek alternatives or conserve, rather than pay more; if oil prices go significantly higher, then the effect is to plunge the industrial world into recession, lowering demand." I am not sure what the price of gas is where you are, but it is still lower than it was last year for me, so I think that the price can increase a little, but I think we are close to that price point.

Looking Ahead: The Commercialization of Algal Biofuel

Today's blog post on Biofuel is the second in a series of post by Alevinia Wang, an intern at Invensys. Alevinia studied biofuels at Washington State University.

Looking Ahead: The Commercialization of Algal Biofuel 

The ubiquitous single celled aquatic plants known as microalgae thrive in both freshwater and marine ecosystems system and are very efficient at converting sunlight into energy through the photosynthetic process. Their efficient use of sunlight and ability to reproduce rapidly allows them to monopolize the majority of aquatic resources in their local environment. These so called ‘’algal blooms’’ can jeopardize the eco-balance in aquatic systems but it is this rapid increase in biomass that has researchers excited to utilize microalgae in biofuel production. An additional benefit of this innovative energy source is that the algae naturally consume CO2 as part of photosynthesis thus diminishing the negative impact on the environment.

Simulation Design of Bioethanol Production

Global production of biofuels is increasing in response to worldwide demand. Simulation software aids not only in the design of environmentally friendly and safe processes, but also helps reduce capital and operating costs. Simulation software provides the functionality and flexibility required to model high fidelity biofuel processes with integrated correlations and reaction models. Process simulation software can be used to improve heat recovery processes, reconcile data, and verify operating conditions. Simulation software contributes to efficient and safe process design. Use of simulation software for the design of biofuels processes is good not only for the environment, but also for the bottom line.

Biofuel: A Renewable Solution for Future Energy Demand by Alevinia Wang

Today's blog post on Biofuel is the first in a series of post by Alevinia Wang, an intern at Invensys. Alevinia studied biofuels at Washington State University.

Biofuel: A Renewable Solution for Future Energy Demand 

The world’s current energy needs are being met primarily with ‘’fossil-fuels’’ which are non-renewable and the use of which creates the majority of the worlds pollution.  Advancements in technology and political regulations have helped curb the environmental impacts of fossil fuel use but it is impossible to escape the eventuality of
simply running out.  As the famed economist Herbert Stein once said, ‘’If something cannot go on forever, it will stop’’.

The solution to this inevitability is Biofuel.  Biofuel is derived from living organisms (biomass) whereas fossil fuel consists of decomposed relics of ancient biomass.  Both Biofuel and Fossil Fuel are energy dense as a result of carbon fixation, however, the obvious difference between the two is the required time of formation (see Figure 1).  Fossil fuel requires many millions of years to form thus making fossil fuel feedstocks (coal, crude oil, and natural gas) non-renewable for all practical purposes.  Biofuel on the other hand is considered renewable because its ‘’cradle to grave’’ energy life cycle can be achieved in months, and is reproduced via photosynthesis and industrial bio-engineering processes.  Furthermore, the photosynthesis required to produce Biofuel effectively recycles the CO2 that is produced during its end use (its conversion to energy).

Thus a significant net reduction of CO2 emissions is anticipated when compared to traditional fuel sources.  A carbon neutral cycle can be achieved by balancing the CO2 emission rate and biofuel production capacity.  The implementation and promotion of biofuel will relieve the economic and environmental stressors caused by fossil fuel depletion, reduce dependency on foreign crude oil importation, and will improve the sustainability of society. 

As biomass is also a primary resource for food production, the question arises: Must we replace a portion our food supply for energy production? The answer is no, not necessarily. The biomass sources can vary widely. Biofuel can be obtained from non-edible organic matter (such as wood chips, microalgae and grasses) and even animal waste.

Despite the wide variety and abundance of biomass resources and the reduction in carbon footprint, biofuel has faced a series of challenges. The greatest issue is the photosynthetic efficiency of plants themselves. Only 47% of the sunlight can be absorbed and utilized by green plants while green light, UV, and IR irradiation is by-passed. In addition, photosynthesis works most effectively in low light-intensity, it reaches its saturated status at about 20% of averaged sunlight intensity. The improvement of photosynthetic efficiency relies on the understanding of the fundamental mechanism of photosynthesis and process coupling in biomass cultivation.

We can conclude that Biofuel is a potential viable option that can ease our thirst for fossil fuel. In order for that to happen, however, the photosynthetic efficiency of the biomass needs to be improved through scientific and industrial efforts. Biofuel production is also the art of thermochemical process by subunit cooperation. Simulation of these processes can help researchers optimize each stage and achieve state-of-the-art levels of efficiency
