Greg Martin Pavilion Technologies Austin, TX 78758 [email protected] Mark Gerules Pavilion Technologies Austin, TX 78758 [email protected] Model Predictive Control (MPC), a control algorithm which uses an optimizer to solve for the optimal control moves over a future time horizon based upon a model of the process, has become a standard control technique in the process industries over the past two ...

Laccase belongs to a small group of enzymes called the blue multicopper oxidases, having the potential ability of oxidation. It belongs to enzymes, which have innate properties of reactive radical production, but its utilization in many fields has been ignored because of its unavailability in the commercial field. There are diverse sources of laccase producing organisms like bacteria, fungi and...

BACKGROUND Work-related skin disease is common but few cases are documented in statutory reports or disability systems. Voluntary reporting by specialist physicians provides more complete information. AIMS To summarize incidence rates of work-related skin diseases reported by consultant dermatologists and occupational physicians, with emphasis on contact and allergic dermatitis by occupation ...

Since the late 1980s, federal legislation has required industries to publicly report their annual emissions of toxic compounds. Industry reports show the largest contributor to toxic emission levels in Texas is the massive concentration of petrochemical industries along the Gulf Coast. It is interesting to note that although Texas produces over 50% of the nation's synthetic chemicals, it discha...

Chemically synthesized 4-hydroxybenzoate (4HBA) is widely used in the chemical and electrical industries as a material for producing polymers such as those of the liquid crystal type. Its alkyl esters, called parabens, have been the most widely used preservatives by the food and cosmetic industries. We report here for the first time a microorganism, a marine bacterium, which biosynthesizes thes...

The importance of automation in the process industries has increased dramatically in recent years. In the highly industrialized countries, process automation serves to enhance product quality, master the whole range of products, improve process safety and plant availability, efficiently utilize resources and lower emissions. In the rapidly developing countries, mass production is the main motiv...

The classical electrostatic image principle for a perfectly conducting object consisting of two orthogonally intersecting spheres is revisited through vector analysis. A method for finding the image of a given charge distribution by splitting it in three virtual singlesphere problems is described. Also, a simple relation between the image charges of a given point charge is found. The method is ...

As an engineering technology, industrial cleaning plays increasingly important role in production; The development of the industry not only provides effective technical services for whole society, but also has become symbol today’s social civilization. With industrialization process country and needs production life, application field is becoming more extensive. emerging dry ice characteristics...

Process plants such as petrochemical units have been continuously trying to improve Health, Safety, Environment and Ergonomics (HSEE) programs. This study proposes an adaptive network-based fuzzy inference system (ANFIS) for assessment of HSEE programs in a petrochemical plant. The proposed neuro-fuzzy approach is applied to a set of operators in the petrochemical unit to show its applicability...

Grape seed is a waste product from the wine and juice industries. However, vegetable oil can be extracted it, which renewable chemical with huge potential application after modifications, such as epoxidation maleinization processes. This paper therefore deals use of grape oil, to produce its epoxidized maleinized derivatives. Both derivatives were synthesized in order improve conversion (99.4%)...
