The residence time in a digester varies with the amount and type of feed material, and with the configuration of the digestion system. In a typical two-stage mesophilic digestion, residence time varies between 15 and 40 days,  while for a single-stage thermophilic digestion, residence times is normally faster and takes around 14 days.

Residence time distribution: In ideal reactors, we assume certain types of flows. In reality, the flows will be different from those assumed patterns. To some extent, the non-ideality in the flow can be quantified using a function called residence time distribution or RTD. This can be used to predict the conversion in the non-ideal reactors.
• Residence Time is one of the most important requirements at an air monitoring station • Determine the ID sizes, length, and flows • Maintain the residence time below 20 seconds to restrict reactivity in the probe line . Contact Information: Laura Niles . Air Pollution Specialist .
affects the residence time in the mill and the power drawn. When the load becomes critically high, the feed needs to be cut in order to "grind the mill out". This dramatic change in mass flow and particle size is passed to the downstream processes, causing recovery to be compromised. MillStar''s Segregated Ore Feed Controller is designed to:
· Referring to FIGS. 1 through 4, a first embodiment of a conical/gyratory crusher provided with residence time control of the material to be crushed in the crushing cavity between the crusher bowl liner and the mantle will be described. A crusher 10 is assembled on a base member 12 having a central hub 14 surrounded by an annular shell 16.
Residence Time. This is a good opportunity to discuss the notion of a residence time for a reservoir. The residence time is effectively the average length of time that an entity, in this case a water molecule, will remain in a reservoir. It is really only meaningful for a …
· Residence time distributions of rock particles in different VSI crusher configurations. An inspection of the distributions shown in Fig. 12 demonstrates that the median residence time of rock particles inside the rotor is very short, estimated at about 0.06 s …
The residence time of a droplet in the dryer is only a few seconds (5–30 s). Since the material is at wet-bulb temperature for much of this time, high gas temperatures of 1,508 to 2,008C may be used, even with thermolabile materials. Get Price
material and product stockpiles to a maximum height of 45 ft. To show compliance with the time limitations listed in this standard permit, subsection (J) requires all RCs to be equipped with a run time meter. Subsection (K) requires production records to be kept at the plant site in accordance with 30 TAC § 116.615(8), General Conditions.
· The residence time of materials in the dryer should be generally greater than 22 min. Under the same condition, the longer the dryer barrel, the longer the material residence time and the higher the heat energy utilization ratio. Fote dryer Therefore, lengthening the dryer barrel is very beneficial to make full use of thermal energy.
· These screens remove any oversized material and redirect these "rejects" to a secondary impact crusher. The rejects are then re-crushed and recycled back into the process. Recycle pumps are used to recirculate the screened slurry back into the pumpbox. This was found to improve oil sands digestion and increase the residence time of the slurry.
Residence time of substance Although the residence time (or lifetime) is often easier to directly estimate than the half-life, the latter can be easier to interpret. It turns out that for first order processes, the half-life is roughly 70% of the lifetime as shown by the equations below. Half-life: k k ln 2 0.693 1/ 2 t = = Residence time: k 1
the residence time, τ. Conceptually, it is the time that certain amount of molecules have remained within a unit volume. For a flow rate Q into a fixed volume reactor V, it is known that the mean residence time ideal is given by: τ= V Q (5) Strictly, the mean residence time for a real flow is given by the following expression:
the average residence time of the bubbles but rather the residence time of each bubble (i.e., the residence time distribution). The total reaction rate was found by summing over all the bubbles in the reactor. For this sum, the distribution of residence times of the bubbles leaving the reactor was required. An under-standing of residence-time ...

· Residence time distribution. Residence time distribution (RTD) should not be confused with residence time. The latter can be determined by noting the time it takes a color marker to show at the exit of the preconditioner. RTD, the average time material stays in the preconditioner, has a characteristic bell-shaped curve.
The use of the dense phase, fluidized bed eliminates axial mixing, increases coarse particle residence time and improves the flotation rate through enhanced bubble-particle interactions. As a result, the rate of recovery is high for both fully-liberated and semiliberated particles. HydroFloat Separators Improve Coarse Particle Recovery through:
Long residence times are typical of the flotation plants because of the high value of the recovered material. A residence time greater than 60 minutes in the main stream of flotation is not uncommon . The main purpose of this work was to investigate the possibility of PGM recovery by reducing the secondary cleaner tails grade to below 2g/t. A
