Reactor fouling

WebSlurry loop reactors have been extensively used in chemical industry, for example, ethylene copolymerization. A classical engineering problem is the timely removal of reaction heat which would otherwise cause particle swelling and aggregation, and thus reactor fouling, operation instability, or even blockage, imposing a high safety risk in production. Lack of … WebThe fouling characteristics of a coker gas oil (CGO) containing measurable amounts of olefins and conjugated olefins were investigated using a bench-scale hot liquid process simulator and a batch autoclave reactor at different temperatures. At low surface temperatures (∼200 °C), the fouling propensity of CGO is very low, and at surface …

WebFouling can create a large secondary time constant that can is particularly detrimental in the near-integrating and true integrating response of vessel temperature. For runaway reactors, the secondary time constant can cause dangerous unsafe operation from a narrowing of the window of allowable reactor temperature controller gains. WebWhat we claim is:1. A method of treating process gases, coming from a gasification reactor, prior to entry of said gases into a system of waste heat utilization, said method occurring in a single pressure container and including the successive steps of:first cooling down said process gases to a temperature of at least 800.degree.

WebFouling of a reactor zone is partially overcome by a periodic increase of the reactor pressure by means of the operation of a control valve located near the reactor exit. The periodic operation of the valve results in an increase of the velocity of the reaction mixture that tears away the polymeric deposits. WebReactor bed fouling can impact throughput, process efficiency and energy costs. As run lengths progress, organic solids and iron sulfide eventually build up on the top of the reactor bed and cause plugging. Plugging causes pressure drops across the reactor bed, limiting …

Fouling is the accumulation of unwanted material on solid surfaces. The fouling materials can consist of either living organisms (biofouling) or a non-living substance (inorganic or organic). Fouling is usually distinguished from other surface-growth phenomena in that it occurs on a surface of a component, system, or plant performing a defined and useful function and that the fouling … WebFouling monitoring. Fouling monitoring and control is crucial to ensure high membrane permeability and, therefore, process performance with minimum operation costs associated with energy requirements and membrane lifetime.
