Application

Oilfield Industry Application Guide

● HEC thickening agent can be used as thickner of the well workover fluid and cementing agent. Help to provide clarification of the low fixed content solution, thus greatly reducing the structural damage to the wells. The liquid thickening by Hydroxyethyl Cellulose can be easily decomposed by acids, enzymes or oxidants, greatly improving the ability to recover hydrocarbons.
● Fluid in the well, HEC is used as proppant carrier. These liquids can be easily cracked through the process.
● HEC configuration using drilling fluid, based on its low solids content, can effectively increase drilling stability. These properties can be used to inhibit the fluid medium to high hardness of the rock and heavy shale or shale drilling.
● Reinforcement in the cement operations, HEC can reduce the hydraulic friction, minimize the loss of rock and water loss.

Q:which equation illustrates the additive inverse? multiple choice?
Answer: C In mathematics, the additive inverse, or opposite, of a number x is the number that, when added to x, yields zero. The additive inverse of X is denoted −X. For example, the additive inverse of 7 is −7, because 7 + (−7) = 0, and the additive inverse of −0.3 is 0.3, because −0.3 + 0.3 = 0. In other words, the additive inverse of a number is the number's negative. For example, the additive inverse of 8 is −8, the additive inverse of 10002 is −10002 and the additive inverse of x² is −(x²). The additive inverse of a number is defined as its inverse element under the binary operation of addition. It can be calculated using multiplication by −1; that is, −n = −1 × n.

Q:Why do additives cause hyperactivity?
Additives for chemicals have different purposes. If you are studying effects of medicines, there are many class of additives. Most common are fillers - This compounds help in preparing dilution for tablating (or other forms of medicines) to help tableting exact dose. These are generally starch or salts. There are some additives being used to encapsulate the medicine. This help in delivering the medicine in the targeted zone. his compounds protect the medicine from being absorbed in region where it is not required - and in most cases it works on pH balance or presence of some specific ions. This compounds indirectly help in improving the efficiency of medicine. Some additives are made to increase the efficiency of the medicine. They are some times other medicine - combination preparations or some enzyme like compounds. It is known as synergistic effect. Increased efficiency - effect of medicines can be identified as hyper activity in body. Some additives are binders - that help tablating.
Q:Bean Additives use, how to add lobster sauce?
Essential production resources (a) production sites. Plant design is reasonable, there should be with the production of raw materials to adapt to the library, processing workshops, finished products, packaging workshop, the production of fermented soybean products enterprises should have the appropriate fermentation sites. Processing workshop must have a good ventilation, packaging workshop should be sealed with disinfection measures, production sites should be separated from the living area. (2) the necessary production equipment. (Such as cooking cans, etc.); 2. Pulping equipment (such as grouting machine, cooking pulp tank, etc.); 3. Cooking equipment (such as cooking cans, etc.); 4. Molding equipment (such as cutting machine, Presses, etc.); 5. Fermentation facilities (such as fermentation cages, drawers, etc.); 6. Drying facilities (such as dryers, etc.); 7. Packaging facilities (such as packaging machines, etc.). In addition to the above equipment, the production enterprises according to their different production processes, must have its corresponding production equipment and facilities. Such as sterilization, frying and other related equipment. Fermented bean milk production enterprises must produce equipment: 1,2,4,5,7. Tempeh, natto production enterprises must produce equipment: 1,3,5,7. Soy milk, lactone tofu and other production enterprises must produce equipment: 1,2,7. Tofu, dried tofu and other production enterprises must produce equipment: 1,2,4,7. Yuba production enterprises must produce equipment: 1,2,4,6,7. (Packaging enterprises must produce equipment: 7.) fried and other soy products production enterprises must produce equipment: 1,2,4,7. (Purchased bean sprouts essential production equipment for enterprises: 7)
