Pyrolysis Distillation Predictor

Predicts NAPTHA and DIESEL purity from distillation column operating conditions.

Inputs

Feature	Description
Distillate_To_Feed_Ratio	Ratio of distillate to feed flow
Feed_Stage	Feed stage number
top_stage_pressure_(bar)	Top stage pressure
Temp_of_Field_(C)	Field temperature
Feed_Flow_Rate_(Kg/hr)	Feed flow rate

Outputs

NAPTHA: predicted purity (0–1)
DIESEL: predicted purity (0–1)

Feasible Operating Zone

Both outputs ≥ 80% when Distillate_To_Feed_Ratio is between 0.20 and 0.44.

Usage

python

import joblib
import numpy as np
from huggingface_hub import hf_hub_download

model_path = hf_hub_download(
    repo_id="lastcode/pyrolysis-distillation-predictor",
    filename="pyrolysis_model.joblib"
)
model = joblib.load(model_path)

# [Distillate_To_Feed_Ratio, Feed_Stage, top_stage_pressure, Temp, Feed_Flow_Rate]
X = np.array([[0.35, 10, 2.5, 150, 1000]])
pred = model.predict(X)
print(f"NAPTHA: {pred[0][0]:.3f}")
print(f"DIESEL: {pred[0][1]:.3f}")
