Biocides & Deposit Control

Deposits and their associated problems in a mill include sticky spots on rolls, plugged fabrics and felts, thin spots and holes in the sheet, breaks, poor run ability and dirt in the final product. Recycled paper which is used for paper- making introduces unique problems of controlling latexes, plastics and stickies. Proses Su Teknolojileri range of micro-biocides, dispersants, boil out chemicals are formulated, to remove build-up of slime, pitch, scale, other debris from dirty machines and process circuits.

Defoamer & Antifoamers

There is an extremely diverse set of chemical formulations, which can be effective either to prevent foam (anti-foam) or to destroy it, once it is formed (defoamer). Most foam- fighting chemicals can serve either role. Proses Su Teknolojileri defoamers act as a dual effective agent for efficient foam control in paper manufacturing systems.

Sugar Industry

Sugar sweet by nature… for thousands of years sugar has been an important food ingredient that provides a balanced sweet taste, safety as a preservative and provides functional properties essential in a multitude of foods. Just as sugar plays a vital role in the growth and life cycle of plants, it is an important ingredient in our food supply.
While all fruits and vegetables produce sugar, the sugar cane and sugar beet plants contain the most accessible stores of sucrose. The sugar that results from sugar cane and sugar beet processing is the same sucrose that is found naturally in the original plants and in fruits and vegetables.
The raw sugar color is removed by physical separation of plant materials and by carbon filters, which absorb colored impurities. A byproduct of the cane and beet sugar refining process is molasses, which has a multitude of uses.

Refining & Processing Sugar

Proses Su Teknolojileri offers chemical solutions that result in better color, higher yields and improved efficiency in sugar and bioethanol production.

– Oil & Gas Industry

Water Chemical Treatment in Oil and Gas Refineries and Pipelines.
Oil and gas refineries handle large volumes of process water and wastewater to carry out daily operations. Process water is used for heat transfer needs, while wastewater is a byproduct of almost every large-scale industrial plant. By treating against scale and corrosion in process water and using bio-augmentation during secondary treatment to reduce wastewater contaminant levels, refineries can extend equipment service life, increase efficiency, and reduce wastewater discharge fees.
When a refinery is built or new equipment is installed, hydrostatic testing is used to check for leaks and pressure capabilities. This is critical for plant safety, not to mention proper equipment functioning. When hydrostatic test water is cycled through the new equipment and drained, it leaves behind a damp environment that encourages corrosion on piping and vessel interiors. If the corrosion propagates, it can lead to equipment contamination or even failure.
A practical and effective way to protect against corrosion during and after hydrostatic testing is by introducing a low dose (0.3-1.0% by volume) amine carboxylate corrosion inhibitor treatment into the hydro testing water. This treatment provides protection without use of nitrites, phosphates etc. and the treated water is relatively simple to dispose.
As the treated hydrostatic testing fluid runs through the vessel, corrosion inhibitors protect the metal surfaces directly in contact with the treated fluid (“contact” corrosion inhibitors), while vapor corrosion inhibitors (VCIs) vaporize out of the hydro testing fluid and adsorb on the metal surfaces in the headspace above the water (e.g., the top of the pipe).

This protective layer is an important factor in attaining full 360° corrosion protection for the hydro tested pipe. After the pipes or vessels have been hydrostatically tested and drained, the corrosion inhibitor formulation leaves behind a protective molecular film on the metal surfaces, protecting against corrosion that could develop from the moisture-ridden environment.
Another water treatment challenge for refineries is the problem of releasing wastewater with a high level of chemical contaminants such as hydrocarbons. Organic contaminants are measured as COD (chemical oxygen demand) and BOD (biological oxygen demand). These contaminants must be degraded either in a wastewater treatment plant located at the facility or pretreated and sent to the local publicly owned or third-party treatment facility for further treatment.
Refineries use biological treatment to remove organic compounds. They can improve efficiency and lower the level of COD/BOD in case of upset by adding microorganisms to the wastewater. These non-pathogenic microorganisms can be specially chosen to target specific contaminant types.

Selection is based on how good the microorganisms are at producing certain enzymes that allow them to digest contaminants as food. For petroleum refineries, this includes microorganisms that aggressively digest hydrocarbons and produce bio-surfactants to sequester contaminants into smaller droplets, making them more available for degradation.
Finally, bio-augmentation is highly effective and can quickly decrease COD/BOD levels, while also reducing bad odors. Microorganisms come packaged in water soluble pouches and are typically applied in a higher initial “shock” dose, followed by a smaller maintenance dose to keep the COD/BOD under control. The best bio-augmentation treatments include a full blend of microorganisms, nutrients, and extra enzymes to enhance performance.

Corrosion, scale, and contaminated wastewater are all standard problems that a refinery has to deal with. Addressing these problems on a regular basis can help maintain healthy systems, increase efficiency, and enhance cost savings in the long run.
