Choosing the right drilling foam

Drilling is an important process in various industries such as oil and gas, tunneling, and dam construction. Using optimal chemicals in this process can have a great impact on improving drilling performance, reducing costs, and increasing productivity. One of these materials is drilling foam or soil amendment foam, which is used as a lubricant and stabilizer in drilling deep wells, semi-deep wells, oil wells, tunneling, dam construction, and other construction projects.

The inhibition rate of industrial mitreh solution against corrosion of carbon steel and stainless steel in DM environment

The aim of this study was to determine the effectiveness of industrial mitreh solution in reducing the corrosion rate of commonly used metals exposed to industrial water environments. The results showed that using mitreh solution significantly reduces the corrosion of metals made of plain carbon steel and stainless steel in DM water.

Efficiency of cold mitreh solution in removing scale from open circuit cooling systems

The purpose of this study was to investigate the effectiveness of Mitreh MDA0102 scale remover solution in industrial water environments according to NACE standards in two environments: calcium carbonate and calcium sulfate, and to compare it with acid washing. According to this study, this solution is a non-corrosive solution, unlike the solutions used in acid washing, which greatly increase corrosion. Also, the results of couponing indicated that the presence of Mitreh vector sediment solution will prevent further corrosion by forming a thin layer on the heat transfer surface.

Introduction and application of antiscalants

Antiscalants are chemical compounds designed to prevent scale formation in water systems. By preventing scale formation on surfaces, these compounds can increase operational efficiency and reduce maintenance costs in industrial water treatment, oil and gas extraction, and desalination processes.

Reasons for cracks in shell/tube exchangers and how to prevent them

Analysis of the causes of cracks in the existing shell/tube exchanger and providing solutions to prevent similar incidents. The shell/tube exchanger is used to regulate the air temperature for drying granules in silos. Due to a leak in this exchanger after 5 years of operation, the tubes were separated from the shell and the tubesheet and tube areas were subjected to non-destructive inspections. It was found that many cracks had formed in the connection between the tubes and the tubesheet on the hot air inlet side, but no defects or discontinuities were observed on the air outlet side.

The effect of lithium bromide on corrosion of metals

The concentration of LiBr in solution can significantly affect the rate and severity of corrosion in metals. The concentration of lithium bromide can increase the corrosion rate, affect the pH of the solution, the formation of corrosion products, the solubility of oxygen, the effects of temperature, and also cause specific metal reactions.

The anti-fouling and corrosion effect of mitreh in heating and cooling systems

One of the main factors of scale in building installations is the presence of calcium carbonate in water, because the solubility of this compound in water is very low and if the conditions are right, it will precipitate quickly. One of the parts that provides these conditions is the surfaces in contact with water in heat exchangers in domestic gas-fired boilers (heat packages).

Caustic corrosion

Localized corrosion caused by the concentration of caustic or alkaline salts, which usually occurs under conditions of high evaporation or heat transfer. Caustic salt or caustic soda is one of the most widely used ionic compounds and is used in various industries including water treatment, cardboard and paper production, oil and refinery industries, aluminum production industries, food industries, alcohol production and glass.

The necessity of using anti-scalants

Almost all problems associated with the use of water for cooling purposes can be attributed to one or more impurities such as hardness salts (such as calcium and magnesium, which deposit as scale in pipes and especially on heating surfaces), silica, iron, microbiological species, oil, and dissolved gases. The scaling and corrosion problems caused by the use of naturally hard water in cooling towers during recirculation pose major economic and technical problems, including reduced system efficiency and increased frequency of chemical cleaning.

Filtration

Filtration is a method of reducing the amount of suspended particles in a liquid by using porous layers. These particles include mud, plankton, paint, organic matter, and other suspended matter. The first filters used were sand and gravel beds, which were called sand filters.

Oil-soluble corrosion inhibitor for the protection of oil transfer and storage equipment

Corrosion is a natural phenomenon that occurs as a result of the electrochemical reaction of metal with the surrounding environment. In the oil and gas industry, corrosion is one of the major problems that accounts for a huge amount of money annually. Part of these amounts are related to the corrosion of pipes or oil transmission lines. Effective ways to prevent corrosion of oil transmission and storage equipment are divided into two categories: physical and chemical solutions.
