What is a slurry chemical engineering?

What is a slurry? Typically, the term slurry is used to refer to a mixture of a liquid and a solid or combination of solids. The liquid is often referred to as the carrier fluid and in most cases is water, although it can be anything from an acid solution (eg nitric acid) to a hydrocarbon (eg diesel).

What is a slurry phase reactor?

Slurry reactors are similar to fluidized-bed reactors in that a gas is passed through a reactor containing solid catalyst particles suspended in a fluid. In slurries, the catalyst is suspended in a liquid, whereas in fluidized beds, the suspending fluid is the reacting gas itself.

How does a slurry reactor work?

A slurry reactor contains the catalyst in a powdered or granular form. This reactor is typically used when one reactant is a gas and the other a liquid while the catalyst is a solid. The reactant gas is put through the liquid and dissolved. It then diffuses onto the catalyst surface.

Which of the is three-phase reactor?

Only trickle bed and slurry reactors are considered the most important, probably, among the class of three-phase reactors.

What is the purpose of slurry?

Slurry is created from cow manure and water and provides a fantastic, natural fertiliser that farmers can use to encourage the growth of grass and other crops. It is usually stored in a slurry tank or lagoon before it is applied to farmland as fertiliser.

What is slurry method?

The drilling fluid, also referred to as slurry or drilling slurry, is used to prevent caving of unstable ground formations and intrusion of groundwater into the drilled hole.

What is a slurry mixture?

Slurry refers to a liquid-solid fluid mixture with a specific gravity greater than 1. The liquid is usually water; however it could be any liquid. Due to this, vessels used to house or transport slurry are often prone to corrosion.

What is slurry phase bioremediation?

Slurry-phase bioremediation is an engineered process for treating contaminated soils or sludges.

What is meant by fixed bed reactor?

Fixed-bed reactors are the main type of catalytic reactors for large-scale chemical synthesis. The process is characterized by different gaseous chemical species reacting on the catalyst surface placed in a fixed position inside the reactor.

What is a 3 phase reactor used for?

Reactors can protect both motors and variable frequency drives (VFDs) from harmful current and voltage spikes. Reactors also help reduce power line distortion, known as harmonics, by adding impedance to the power system.

What is the function of a reactor?

The main job of a reactor is to house and control nuclear fission—a process where atoms split and release energy.

What is slurry technology?

Slurry technology solution allows refiners to mitigate low value fuel production. The heart of the process is a slurry reactor that hydrocracks heavy feed into lighter products in the presence of the slurry molybdenum based catalyst.

What chemicals are in slurry?

Slurry gas is a mixture of gases including methane, carbon dioxide, ammonia and hydrogen sulphide, all produced by bacteria during the decomposition of slurry. All these gases are unpleasant; some are also poisonous as well as being flammable.

What are the two different types of bioremediation?

In-situ bioremediation is two types; these are intrinsic and engineered bioremediation. Intrinsic bioremediation also known as natural reduction is an in-situ bioremediation technique, which involves passive remediation of polluted sites, without any external force (human intervention).

What is the difference between packed bed and fluidized bed?

Excellent mixing of reactants in the fluidised bed helps to minimise temperature variations and renders this system attractive for carrying out gas–solid reactions. The fluidised bed reactors show better conversion of reactants in comparison with packed beds when solid reactants are used in the form of small pellets.
