- class BatchBioreactor(ID='', ins=None, outs=(), thermo=None, **kwargs)#
Abstract Bioreactor class. Conversion is based on reaction time, tau. Cleaning and unloading time,`tau_0`, fraction of working volume, V_wf, and number of reactors, N_reactors, are attributes that can be changed. The cost of a reactor is based on the NREL batch fermentation tank cost assuming volumetric scaling with a 6/10th exponent .
Must set outlet stream flows.
Stream], optional) – Inlet fluids to be mixed into the reactor.
Stream], optional) –
tau (float) – Reaction time [hr].
N (int, optional) – Number of batch reactors
V (float, optional) – Target volume of reactors [m^3].
T=305.15 (float) – Operating temperature of reactor [K].
P=101325 (float) – Operating pressure of reactor [Pa].
Nmin=2 (int) – Minimum number of fermentors.
Nmax=36 (int) – Maximum number of fermentors.
Either N or V must be given.
- autoselect_N = False#
[bool] If True, number of reactors (N) is chosen as to minimize installation cost in every simulation. Otherwise, N remains constant.
- tau_0 = 3#
[float] Cleaning and unloading time (hr).
- V_wf = 0.9#
[float] Fraction of filled tank to total tank volume.
- property effluent#
outs when the number of outlets is 1.
- property N#
[int] Number of reactor.
- property V#
[float] Reactor volume.

class-attribute Name denoting the type of Unit class. Defaults to the class name of the first child class
All heat utilities associated to unit. Cooling and heating requirements are stored here (including auxiliary requirements).
Electric utility associated to unit (including auxiliary requirements).
All bare-module factors for each purchase cost. Defaults to values in the class attribute
All design requirements excluding utility requirements and detailed auxiliary unit requirements.
All baseline purchase costs without accounting for design, pressure, and material factors.
Itemized purchase costs (including auxiliary units) accounting for design, pressure, and material factors (i.e.,
F_M). Items here are automatically updated at the end of unit simulation.
All installed costs accounting for bare module, design, pressure, and material factors. Items here are automatically updated at the end of unit simulation.
Lifetime of equipment. Defaults to values in the class attribute
_default_equipment_lifetime. Use an integer to specify the lifetime for all items in the unit purchase costs. Use a dictionary to specify the lifetime of each purchase cost item.
Whether to run mass and energy balance after calling specification functions
Name-number pairs of baseline purchase costs and auxiliary unit operations in parallel. Use ‘self’ to refer to the main unit. Capital and heat and power utilities in parallel will become proportional to this value.
