CN1184486A - Method for preventing fouling & …
A method for preventing sheeting problems in a gas phase reactor in such multi-phase polymerization process, which comprises at least one loop reactor followed by a gas phase reactor, where the polymerization is continued in the presence of added monomers, and in which process a fouling preventive agent is used to prevent fouling or sheeting in the reactors.
Understanding and preventing heat exchanger …
Preventing and reducing fouling. In all cases, prevention is better than cure. Preventing or reducing fouling will be cheaper and more effective in maintaining heat exchanger performance than removal or cleaning. Some methods to reduce each type of fouling have already been discussed. Using corrugated tubes in heat exchanger construction, as HRS does, is beneficial in preventing both ...
A method of preventing fouling in the …
A method of preventing fouling in the reactor circulation in the polymerization of alpha-olefins in the presence of a catalyst to obtain a product in the form of particles by introducing into the reactor agent that prevents fouling of the emer alpha-olefin to Acrylonitrile and polyamine, representing the product of the polymerization of aliphatic primary mono - or diamine with epichlorohydrin ...
US Patent for Method for preventing fouling of a …
A method for preventing fouling of a demister is disclosed. A process fluid is provided into a vessel. A gas is provided to a gas inlet of the vessel. The gas comprises a component that desublimates, crystallizes, solidifies, reacts, or a combination thereof, in the process fluid, forming a first solid. The gas is passed through the process fluid, the component of the gas forming the first ...
Methods of preventing protein fouling and …
WO 2004/104271 PCT/NZ2004/000098 Methods of preventing protein fouling and compositions therefor FIELD The present invention relates to novel methods and compositions for preventing protein 5 fouling on surfaces particularly, but not exclusively, stainless steel surfaces.

New fouling prevention method using a plasma …
New plasma-based method is introduced to prevent mineral fouling in produced water. • Plasma arc discharge removed bicarbonate ions in produced water. • CaCO 3 fouling was prevented in heat transfer surface with zero bicarbonate ions. • Excessively high Ca 2 + ions in water did not cause CaCO 3 fouling …
What Is Membrane Fouling and How Can You …
Preventing membrane fouling is best accomplished by good planning and design. There are many variables that play a role in proper system function for a membrane filtration system, each of which should be considered when replacing a membrane or installing a new system. These include:
Fouling - Wikipedia
Fouling is the accumulation of unwanted material on solid surfaces to the detriment of function. ... The most fundamental and usually preferred method of controlling fouling is to prevent the ingress of the fouling species into the cooling water circuit. In steam power stations and other major industrial installations of water technology, macro fouling is avoided by way of pre-filtration and ...
US Patent for Methods for reducing surface …
Methods for preventing or reducing fouling of equipment having a metal surface that contacts a reaction byproduct in a fuel production system are provided. The method may include treating the metal surface in the fuel production system by contacting a fouling inhibitor with the metal surface. The fouling inhibitor includes a bicyclic organic compound with an aromatic ring and a heterocyclic ...
Advances in Marine Antifouling Coatings and …
However, the environmental impact of antifouling biocides is of increasing concern and the search is ongoing for non-toxic methods to prevent biofouling. In addition to silicone fouling-release coatings and surface modification (considered elsewhere in this volume), fluorinated polymer coatings, smart polymers, hydrophilic surfaces, fibre coatings, scrubbable and inert coatings and non ...

01.08.2000 · A method for preventing sheeting problems in a gas phase reactor in such multi-phase polymerization process, which comprises at least one loop reactor followed by a gas phase reactor, where the polymerization is continued in the presence of added monomers, and in which process a fouling preventive agent is used to prevent fouling or sheeting in the reactors.
Method of preventing corrosion and fouling by …
On May 28, 1974, a United States Patent Application, Serial No. 473,691, was filed on a new process for preventing corrosion in steel substrates subjected to marine environments, and for preventing bio‐fouling so common in those situations. The patent application also applies to other substrates which have only the bio‐fouling problem but may not be subject to corrosion, such as fibreglass ...
METHOD AND DEVICE FOR PREVENTING …
The invention relates to a method and device for preventing fouling by shellfish in technical apparatus fed with seawater or fresh water, such as cooling equipment of power plants or the stone industry. According to the invention, the surface water to be taken in, destined for the industrial apparatus, is guided along a suitable substrate, onto which substrate shellfish grow, so that in the ...
