LABSA Industry Calculator & Calculation Book
LABSA Industry Calculator
Parametric calculation book for preliminary planning of LABSA 90% / acid-slurry plants
1. Design Inputs
TPD = metric tonnes of finished LABSA product per operating day.
Raw-material basis
Editable design assumption. The report gives 670–690 kg per tonne of 89 ± 1% acid slurry.
Editable design assumption. The report's mass-balance basis gives 1.500 MT acid per 1.470 MT LABSA.
Editable. Reported mass balance corresponds to 250 kg water / 1.470 MT LABSA.
Editable. Reported annual figures imply a different ratio; keep this assumption explicit.
Utilities
Initial value derived from the report's 18 KLD / 72 TPD ratio.
Initial value = 100 kVA / 72 TPD from the report. Replace with an actual load study.
Report: 82 kVA DG against 100 kVA stated electrical requirement.
Storage assumptions

Utility values are preliminary planning calculations. Final electrical, water, cooling, ventilation, instrumentation and process-safety loads require an engineering design basis.

8. Report-Derived Reference Notes
Your sample report: the reported reference project is 72 TPD LABSA, with 21,600 MT/year stated at 300 operating days/year. It also reports 1,300 MT/month LAB, 2,000 MT/month 98% sulphuric acid, 12 KLD process water and 18 KLD total water.
Important: the source contains inconsistencies. Examples include different land areas, highway identifiers, reaction times, terminology for the acid by-product, and 100 HP versus 100 kVA. This calculator deliberately does not silently “fix” those values. Instead, the user enters the design basis.

10. Engineering Boundary
This calculator is intended for pre-feasibility, comparison and educational planning. It is not a process design package. It does not calculate reactor dimensions, sulphonation kinetics, heat-transfer area, pressure drop, acid-resistant materials of construction, HAZOP/LOPA, relief devices, emissions compliance, detailed electrical distribution, fire protection, civil design, or statutory approvals.

## Source handling
The sample report was used as the initial reference basis, but conflicting source values were not silently merged. Key assumptions are exposed as inputs so an engineer/user can choose the verified design basis.
The default 72 TPD reference is from the supplied report. The report also states 300 operating days/year and 21,600 MT/year. The calculator therefore starts at 72 × 300 = 21,600 MT/year.
## Important technical limitation
This is a pre-feasibility calculation tool, not a detailed LABSA process-design package. It does not calculate sulphonation kinetics, reactor dimensions, heat-exchanger area, pressure drop, materials of construction, relief systems, HAZOP/LOPA, fire protection, emissions compliance, detailed electrical design, civil works or regulatory approvals.
Before commercial/engineering use, replace every editable assumption with values from a verified process design basis and applicable standards.
