Gulf Coast Area

Reduced heavy infestations by >70% in upper Gulf Coast area of Texas... 

In the U.S., the primary methanol production location is in the Gulf Coast area. Methanol is also produced in Canada, South America, Europe, and the Middle East. Methanol production and price is not controlled by any single country or consortium of countries. Any country with remote natural gas reserves is a candidate for methanol production since production of methanol usually represents the most cost-effective means of developing those reserves. 

The occurrence of sulfur in the form of simple and complex sulfides of the heavy metals has already been discussed. Of greater consequence, however, are the vast underground deposits of nearly pure elemental sulfur found in the Gulf Coast areas of Louisiana and Texas. Less extensive and less pure deposits of elemental sulfur are also found in a number of other countries, principally Sicily, Spain, Chile, Mexico, and Japan. 

Table III shows the effect of shifting furnace operation from propane fresh feed to ethane. Data are from Schutt and Zdonik (54). The reduction of propylene yield from ethane to negligible levels in favor of increased ethylene production cannot be done if a plant has propylene commitments. Because propylene requirements cannot be satisfied with ethane feed, Ericsson (14) has concluded that propane will continue to be the preferred feedstock to make ethylene. Actually, 85% of the U.S. ethylene plants are located in the Gulf Coast area so that they can obtain and operate on economical ethane and propane feeds. The need for propane pyrolysis has resulted in a renewal of experimental interest in this area, and in-depth studies have been made by Crynes and Albright (17) and by Buekens and Froment (7).

Fuel. The best plan is to locate near large coal fields if coal is the primary fuel or to tie up by long contracts sufficient gas and/or oil to ensure the continuity of operations over a long term. The Gulf Coast area has been built up in the past 15 years largely because of plentiful and cheap gas. When gas is the basic raw material, as in ammonia synthesis, synthetic gasoline, it is the controlling economic factor as it supplies the raw materials, heat, and power. 

For in-plant personnel, and especially for offsite persons, the map or the plot plan is an effective way to describe the size and the location of the site. It also helps locate where the emergency has developed. When the risk management program (RMP) was being developed by the companies of the Gulf Coast area, computer-based maps were extensively used to display the areas in and around the plants. 

In many companies, investment site factors, F,sp, are used to multiply the total permanent investment, Cppi, to account for different costs in different localities, based on the availability of labor, the efficiency of the workforce, local rules and customs, union status, and other items. Typical factors in recent use by one of the major chemical companies are provided in Table 16.13, where a plant in the U.S. Gulf Coast area is given a base factor of 1.0. The factors range from 0.85 in India to 1.25 in the U.S. West Coast area. The corrected total permanent investment is computed as ... 

The Jurassic Smackover formation does not outcrop and is only encountered in subsurface penetrations located in the U.S. Gulf Coast area. 

Some bacteria, although naturally occurring, are known to cause diseases in humans, especially those with compromised immunity. For example, in the United States Gulf Coast areas. Vibrio vulnificus causes illness or even death in immunocompromised individuals who consume bacteria-contaminated shellfish [75,127,146]. In coastal waters of New England in the United States, V. parahaemolyticus, another naturally occurring bacterium, has been implicated in leg gangrene and endotoxin shock in humans [118]. 

Dowell did introduce a mixture of 12% HCl-3% HF, called mud acid, in 1939. The purpose of this mud add was to remove drilling-mud filter cake from the wellbore. However, use was limited to wellbore treatment only. Successful treatments were pumped in the Gulf Coast area. ...
