Thermodynamics
This type of steam is best utilized for power generation; it expands to perform useful work
What is superheated steam?
This Mosaic site has the highest power generation per ton of sulfuric acid ("KilowattHr per Ton")
What is South Pierce
This is the major component of the turbine generator attached to the turbine wheel sections and an electromagnet. It spins.
The rotor / spindle / shaft
New Wales can send power to this beneficiation plant
What is Four Corners
Unfortunately, this water management strategy consumes a lot of steam.
What is the RO; also, what is UIC (Underground Injection)
This process equipment ensures that steam feeding the evaporators does not exceed 10 degrees of superheat
What is a desuperheater
The sulfuric acid production process is highly exothermic. Name 3 places in the sulfuric acid plant where heat is generated.
The furnace/burner, the converter, the absorption towers (Drying, final, IP, HRS), and heat of dilution (pump tank). Auxiliary boiler...
This term describes steam removed from the turbine at an intermediate stage, so that it can be utilized for heating.
What is extraction
This heavy mining equipment consumes roughly 3 MW
What is a dragline
Acid dilution will cause these phos acid plant units to consume more low pressure steam.
What are the evaporators
This is Mosaic's preferred unit of measure when dealing with specific quantities of purchased or sold electricity.
Megawatt-HOURS
This sulfuric acid plant upgrade replaces the IPA tower and IP acid cooler with a 2-stage absorption tower and a medium-pressure boiler circuit.
What is HRS (Heat Recovery System)
Loss of vacuum in this unit will decrease overall power generation.
What is the (surface) condenser
The motors of these units in the rock grinding area disengage automatically when in Standby mode (no feed).
What are the ball mills
When the evaporators are in need of more low-pressure steam, the TG chief or controller will open this valve.
What is V2
In a 100% efficient turbine, steam will expand at constant ___ ?
Entropy
This asset recovers some process heat, usually from the sulfuric acid pump tank, and transfers it to boiler feed water.
What is a preheater / trim cooler
This section of the generator is where electrical power is produced. Water, air or hydrogen is circulated to cool the copper windings.
What is the stator
This term describes what happens when a Mosaic plant is in "island mode" and there is not enough electricity for everyone.
What is load shedding
This Mosaic fertilizer product requires more steam than its micros siblings (bonus points - second-highest is...)
GMAP (second highest is S9)
Steam passing through a letdown valve is a _____ process.
Isenthalpic
Increasing this setpoint will result in higher steam generation. It will also allow the sulfuric acid plant's Main Blower Turbine to consume less high-pressure steam.
What is furnace gas strength (%SO2)
No pressure drop occurs across this type of turbine blade. Steam passes through a nozzle and strikes the blade, causing rotation.
What is an impulse turbine blade
These pumps are typically the most power-hungry at the concentrates facilities
What are gypsum slurry and pond water pumps
When the price of natural gas is high, it is good to use this steam-consuming asset located in the dry products plants.
What is the preheater
