what is thps biocide?

2021-01-13

1、THPS biocide is an environmentally friendly water treatment biocide made from a 75% solution of tetrahydroxymethyl phosphonium sulfate (THPS).

 

It can inhibit sulfate-reducing bacteria (SRB) and most aerobic bacteria, including water injection equipment, well water treatment facilities, water storage tanks, circulating water treatment systems, and pipelines to form biofilms and other auxiliary systems for oil recovery technology, production, etc. THPS biocide can also effectively control microbial growth in oil and gas well dredging and stimulation fluids.

 

THPS is characterized by its low solid point and good stability. 75% solution of THPS is readily soluble in water and can be stored for long periods of time. vcycletech was recognized by the U.S. Environmental Protection Agency as zero toxicity in 1995 and received the U.S. Green Chemistry Award for its high efficiency, low toxicity, and low residue properties.

2.Insecticide biocidal mechanism of action.

 

Water immersion.

THPS fungicide should be added to the water flooding system and mixed uniformly at one point. Step 1:Add 93-350ppm of THPS to an apparently contaminated system. When adding to a flowing system, snail dose at a flow rate of 2 to 6 hours. Repeat as needed until control is achieved—step 2. Once control is achieved, add 14-98ppm of THPS fungicide weekly or as needed to maintain control. As for continuous treatment, THPS can be added continuously at levels of 14-67 ppm.

 

Oil and gas production and transmission systems and piping.

A 75% solution of THPS should be added to the pipeline where it is well mixed. An amount of biocide should be added at the time of application to ensure maximum distribution of the product through the pipe's inner surface and eventually out the other end of the pipe. The criteria for successful treatment is a reduction in bacteria count and/or corrosion rate. The addition procedure is the same as for the water immersion method. As for continuous treatment, THPS can be dosed continuously at the 14-100 ppm-level.

 

Drilling Mud, Completion Fluids, and Workover Fluids.

THPS biocide should be added to these fluids where they are well mixed. Depending on the severity of contamination, 33-1400 ppm will be added to the newly prepared fluids.

 

Gas Storage Well Systems.

Individual injection wells should be treated with THPS75 at the same dose and in the same procedure as described for water flooding. Repeat injections as needed to maintain control. Individual water drop wells should be treated with a sufficient quantity of product, diluted by the water in the water drop well, to produce a 33.3-133.3 ppm concentration. Repeat injections as needed to maintain control. Some oilfield drilling service companies in the U.S. and Canada are beginning to use xanthan gum, THPS biocide, and Curdlan gum for irrigation treatments.

 

3How to Choose A THPS Manufacturer

 

Tetrahydroxymethyl Processing Sulfate (THPS) is mainly used as a fungicide. The main advantage of THPS fungicide is that it decomposes rapidly into a completely harmless substance after use and is widely used in water treatment, oil field, paper making, and other industries. Therefore, it is widely used in water treatment, oil field, paper making, and other industries.

 

THPS chemicals can also be used as a permanent flame retardant for cotton and polyester/cotton fabrics.

 

THPS biocides need to be stored in a cool, ventilated warehouse. It must be kept away from fire and heat. And keep the container sealed.

 

THPS should be stored separately from oxidizers, acids, and food chemicals.

 

The purity of THPS chemicals varies from manufacturer to manufacturer, and the price of THPS varies. Therefore, it is essential to choose a reliable THPS manufacturer.

 

The competition in the chemical industry is not only between companies. It is a competition between supply chains. Growth in volume and efficiency throughout the supply chain can drive the entire industry. Current data shows that raw material problems cause more than 60% of a company's final product quality problems. Therefore, it is crucial to improve product quality. This problem cannot be solved by internal business operations alone.

 

Focus on the supply chain. Managing material quality from the raw material supplier to the THPS manufacturer is critical. Most THPS chemical companies encounter several difficulties. Insufficient supplier information, troublesome supplier management, and lack of effective monitoring. More important is the lack of feedback mechanisms to suppliers.

 

A terrible trading relationship emerges between manufacturers and suppliers. Lack of good communication has become an obstacle to the upstream and downstream partnership.

 

THPS suppliers may not be THPS manufacturers. This largely depends on whether the supplier produces the THPS product. The manufacturer is the producer of the product. It can also be a supplier. The world's leading chemical companies have been doing this. Examples include BASF, Dow, DuPont, Huntsman, etc.

 

High-quality THPS requires qualified production of raw materials, mature processes, perfect production equipment, and strict quality inspection. Only with these conditions can we become a trustworthy THPS producer.

 

Due to the diversity of raw materials and the complexity of the production process. The quality of produced THPS is always different. The quality of the product varies from product to product. This leads to differences in the price of THPS on the market.

 

Among other things, chemical reactions and reactors are at the heart of THPS production. The role of the physical processes is to prepare the appropriate reaction conditions for the chemical reactions. For example, separating and purifying the reactants to obtain the final product.

 

IRO fungicide products include conventional fungicides such as aldehydes, halogens, environmental fungicides, hydantoin, and isoxazolines.
