Industrial Process Steam (IndustrialProcessSteam)

Class: IndustrialProcessSteam | Module: energysim.models.loads | Validation benchmarks | Units

Overview

Industrial process steam demand header for refineries and chemical plants.

Quasi-static: demand = setpoint (>= 0), deficit = max(0, demand - supply), thermal demand = demand x enthalpy. No header pressure dynamics.

Parameters

Parameter	Type	Default	Unit	Description
name	str	'SteamHeader'	-	Unique component name identifier
nominal_demand_t_hr	float	100.0	t/h	Nominal process steam demand
enthalpy_kj_kg	float	2800.0	kJ/kg	-
step_size	float	1.0	s	-

Inputs

Variable	Unit	Description
steam_supply_t_hr	t/h	-
demand_setpoint_t_hr	t/h	-

Outputs

Variable	Unit	Description
steam_demand_t_hr	t/h	Process steam demand
steam_deficit_t_hr	t/h	Unmet steam demand
Q_demand_MW_th	MW	Thermal power equivalent of the steam demand

Validity and notes

Validity: quasi-static demand header; no pressure, temperature or condensate-return dynamics; constant specific enthalpy.

Usage example

from energysim import world
from energysim.models import IndustrialProcessSteam

sim = world(start_time=0, stop_time=3600, t_macro=900)
sim.add_model('industrialprocesssteam', model=IndustrialProcessSteam(), outputs=['steam_demand_t_hr', 'steam_deficit_t_hr', 'Q_demand_MW_th'], step_size=60)
res = sim.simulate()
print(res['industrialprocesssteam'].tail(2))
