Descaling Principle of Oil Field Scale Inhibitor

Descaling Principle of Oil Field Scale Inhibitor In the middle and late stage of oilfield exploitation, the amount of water injection increased. The water content of crude oil increased, and the water quality became increasingly complex. This makes the quality of crude oil worse and worse, and the composition of scale changes from single to complex. Crude oil processing conditions have also become worse. Hazards of Fouling in Oilfield Equipment and Pipelines In addition to CaCO3, CaSO4, SrSO4, and BaSO4 scales, there are also FeS, MgCO3, MgSO4, Mg(OH)2, Ca3(PO4)2, SiO2 and the like. The scaling problem [...]

Selection and Use of Biocides in Water Treatment Chemicals

Selection and Use of Biocides in Water Treatment Chemicals Water treatment chemicals are one of the most widely used and special products in the water industry, pollution control, and water reuse treatment projects. Water treatment chemicals include flocculants, scale inhibitors, corrosion inhibitors, and biocides. Water treatment chemicals are used to remove suspended solids and toxic substances from water and to control fouling. Also used to reduce corrosion of water contact materials. At the same time, water treatment chemicals also have good performance in deodorization, bleaching, softening, stable water quality and desalination. The performance of the water [...]

Oil and Gas Water Treatment Analysis 2018

Oil and Gas Water Treatment Analysis 2018 Relying on the formation of natural pressure oil production is called "primary oil recovery." As the formation pressure drops, it is necessary to use the water injection pressure method to produce oil called “secondary oil recovery”. According to calculations, primary oil recovery can only reach 20%-30% recovery, and secondary oil recovery can only reach one-third of formation reserves. In order to extract the remaining reserves, physical, chemical and biological methods are needed to enhance the recovery factor, called EOR, or “third oil recovery”. Most of the developed oil fields have entered [...]

HEDP Chemical Water Treatment in 2018

HEDP Chemical Water Treatment in 2018 Industrial water treatment includes every process that aims to treat wastewater produced by industries around the world. Nowadays, Water treatment systems vary a lot. They can range from a relatively simple process to a complicated one that serves a wide range of applications. The main purpose of an industrial water treatment system is to treat water in a way. So that it more suitable for a specific use. That use could be consumption, manufacturing or just disposal. Some of the most well-known industrial water treatment methods include the following: wastewater treatment system, [...]

Phosphonate Testing and Reporting

Phosphonate Testing and Reporting There are two fundamental approaches to testing for phosphonates in cooling water, each based on the reaction between a metal and a complexing agent (phosphate or phosphonate). Both reactions are accompanied by the development of a distinguishable color, measurable either by a comparator, colorimeter, photospectrometer or by titration. The "Total Phosphate" method is based on the amount of orthophosphate produced by the degradation or phosphonates. The oxidation can be accomplished photochemically or by heat in the presence of appropriate chemicals. The "Phosphonate" direct reading method is based on titration with an appropriate metal (usually [...]

Chemical Water Treatment for 6 Types of Water in Power Plants

Chemical Water Treatment for 6 Types of Water in Power Plants Since some thermal equipment in a power plant may be exposed to some substances in the water. Those substances produce harmful components and cause corrosion of the equipment. For this reason, the safe operation of the power plant has a direct relationship with the chemical water treatment system. Impurities in the water can damage equipment. The water in the power plant must be treated before it can be used. The treatment program is the chemical water treatment system in the power plant. I. Development and Current Status [...]

Microflora Analysis of 24 Microorganisms in Water Treatment (part 2)

Microflora Analysis of 24 Microorganisms and Their Guiding Significance in Water Treatment (part 2) Microorganisms play an important role in wastewater treatment indicators during the commissioning, operation and process adjustment of biochemical systems in wastewater treatment plants. By microscopically checking the microbial status in the activated sludge, the water treatment enterprise can obtain the relevant trait information of the activated sludge, which plays a guiding role in the production. The previous article "Microflora Analysis of 24 Microorganisms and Their Guiding Significance in Water Treatment (part 1)" mentioned the first 12 species of 24 microorganisms used as indicators. In [...]

Microflora Analysis of 24 Microorganisms in Water Treatment (part 1)

Microflora Analysis of 24 Microorganisms and Their Guiding Significance in Water Treatment (part 1) Microorganisms play an important role in the sewage treatment plant biochemical system debugging, later stable operation and process adjustment. They are good sewage treatment indicators. By microscopically examining the microbiological status of activated sludge, relevant trait information of the activated sludge can be obtained, which will play a certain role in guiding the production. IRO has organized and sorted out the characteristics of 24 kinds of microorganisms, living environment and the impact on sewage treatment. This is part 1 (12 kinds of microorganisms). [...]

What Is the Performance of HEDP 60 in Industrial Production?

What Is the Performance of HEDP 60 in Industrial Production? HEDP 60 refers to the proportion of active HEDP components in solution reaching 60%. Why is the HEDP 60 liquid so popular? This is because cost performance of HEDP 60% is satisfactory. HEDP 60 has been developed as a corrosion inhibitor for many years. The United States, China, Germany, and other countries have conducted in-depth studies. Organic phosphine compounds that can be used as corrosion inhibitors mainly include organic acids and their salt derivatives. Among them, organic phosphonates are very popular as a corrosion and scale inhibitor. Organic [...]

The Performance of Organic Phosphonate HEDP in Water Treatment

The Performance of Organic Phosphonate HEDP in Water Treatment Chemical water treatment is a chemical technique that uses chemicals to eliminate and prevent scaling, reduce corrosion, kill bacteria and algae, and purify water. In the water treatment industry, chemicals are generally used to perform these tasks. Using flocculants to remove mechanical impurities in raw water.  Using scale inhibitors to prevent scaling. Using fungicides to stop the growth of harmful microorganisms. Cleaning agent removes rust residue, old scale, and oil stains. There are three main types of water treatment chemicals: flocculants, biocides, and scale inhibitors. The flocculants are to [...]
