Large Essentia Smeltery

The Large Essentia Smeltery (LES) is an IV tier multiblock for smelting down items into essentia. The LES is a direct upgrade from the Advanced Alchemical Furnace because it runs at 100-200% speed, offers up to 64 parallels, supports multi-amp and laser energy hatches, and runs unlimited perfect overclocks. The speed scales with the amount of perditio centivis (CV) provided and the number of parallels scales with both the length of the machine and the tier of the essentia diffusion cells. However, the processing time of recipes is directly proportional to the output vis so parallels do not actually increase the throughput of the machine. The LES also requires both aqua and ignis CV to run, and optionally ordo CV to reduce the amount of pollution and flux gas released from the muffler hatches every second. In all, the LES can be very powerful but it is quite expensive to build/sustain and is generally not worth it over world acceleratoring the Advanced Alchemical Furnace.

The length of the LES ranges from 5-9 blocks long and together with the essentia diffusion cells determines the maximum number of parallels. All top center casings must be muffler hatches but the remaining buses/hatches may replace any magic casing anywhere on the structure. Multi-amp and laser energy hatches are supported for serious overclocking. Use the Multiblock Structure Hologram Projector to visualize/build the structure with subchannel "essentia_cell" to specify the tier of the essentia diffusion cells and the projector stack size to specify the length of the machine.

Unique to the LES is the essentia output hatch which buffers up to 256 total essentia and outputs to any connected essentia tubes or a warded jar directly below the hatch. The ME essentia output hatch is very similar except it has no buffer and outputs to essentia storage cells on an AE2 network. The latter is effectively required for very large or dense crafts.

Vis Relay

Use vis relays to extract centivis (CV) from nearby energized node(s) and transport it to the LES. Vis relays must be within 8 blocks of an energized node to connect and are limited to a single source connection but may have any number of output connections. The final output connection must be within four blocks of the LES to power it, as seen in the image above. If multiple nodes are connected, then their CV amounts are summed together.

Wallsharing

LES may wallshare each other sides to save on casings, warded glass, and buses/hatches. That does not include the muffler hatches because they must be able to output both pollution and flux gas. Only one LES is ever needed anyway due to its speed and perfect overclocks.

The LES is a direct upgrade from the Advanced Alchemical Furnace because it runs at 100-200% speed, offers up to 64 parallels, supports multi-amp and laser energy hatches, and has unlimited perfect overclocks. The speed scales with the amount of perditio CV provided and the number of parallels scales with both the length of the machine and the tier (${\displaystyle {\displaystyle {\text{T}}}}$) of the essentia diffusion cells, as seen in the following equations. The perditio CV is completely optional and caps out at 100 CV/t.

The base power consumption of the LES is 480 EU/t (HV) regardless of the current voltage of the energy hatch or the current tier of the essentia diffusion cells. The base duration of each recipe depends on both the total amount of output vis and the overall processing speed of the machine, as seen in the following equation. That means parallels do not actually increase the speed of the machine since their output vis are directly proportional to the length of the recipe--they are equivalent to batch mode in this scenario.

${\displaystyle {\displaystyle {\text{Base Duration (s)}}=\lceil {\text{Output Vis}}\times 32\times {\text{Duration Mult}}\rceil \times 0.05}}$

In addition to power and the items to be smelted into essentia, the LES requires a minimum amount of aqua and ignis CV to run. The amount scales with the maximum voltage tier of the energy hatch(es), as seen in the following equation and table. Using multiple energy hatches or increasing their amperage can perfect overclock the LES but does NOT increase the required aqua or ignis CV since their rates are based strictly on voltage. Therefore, always upgrade amperage before voltage to keep costs as low as possible.

${\displaystyle {\displaystyle {\text{Aqua CV/t}}={\text{Ignis CV/t}}=\lfloor {\text{Voltage Tier}}^{2}\times 1.15\rfloor }}$

The LES releases pollution and flux gas from its muffler hatches every second while active, but both can be reduced down to almost nothing by increasing the purity of the machine with ordo CV. The purity changes every five ticks regardless of the state of the machine and decreases by an additional -1% per tick while the machine is active. In other words, the purity generally increases while idle and decreases while active, but it depends on the exact amount of ordo CV, as seen in the following equations and table. Right-click the controller with a Portable Scanner or use an industrial information panel to view the current purity along with a few other stats like its processing speed and parallels.

Note that even above 120 CV/t the purity oscillates between 95-100% which leaves a small chance for pollution and flux gas to release; the LES has no perfectly stable state with zero emissions. One solution is surrounding the machine with Tainthistles from Botania to slurp up the flux gas as it is released and generate a bit of mana in the process, but the gas disappears harmlessly once it escapes the world anyway.

The total pollution per second is a simple linear equation that scales with the purity of the machine. Increasing the length of the LES or adding more muffler hatches does not increase the overall pollution because it is evenly divided between all the ones available.

${\displaystyle {\displaystyle {\text{gibbl/s}}=22\times (100-{\text{Purity}}\%)}}$

The flux gas is a little more complicated. On every running tick, there is first a 5% chance to even consider generating flux gas and if that passes then there is a ${\displaystyle {\displaystyle 100-{\text{Purity}}\%}}$ chance to actually generate the flux gas from a single muffler hatch at random. The flux gas slowly floats upwards and stacks on ceilings or other obstructions until it finally escapes the world. Again, flux gas is harmless if you do not touch it and let it disappear naturally.
