The source report's nominal 72 TPD capacity and 300 operating days/year give 21,600 MT/year LABSA.

Reconciled Mass Balance

Source batch basis: 1.000 MT LAB + 1.500 MT 98% H₂SO₄ + 0.250 MT water = 2.750 MT total input.

Calculation Basis & Reconciliation Notes

These notes make the calculator transparent rather than hiding unresolved source-document differences.

Primary mass-balance basis:
1.000 MT LAB + 1.500 MT 98% H₂SO₄ + 0.250 MT water = 1.470 MT LABSA + 1.280 MT diluted H₂SO₄.
ParameterCalculator basisSource-document treatment
LABSA capacity 72 TPD Source-reported nominal capacity
Annual operation 300 days/year Used to reproduce 21,600 MT/year
LAB consumption 680.27 kg/MT LABSA Derived from 1.000 / 1.470 source mass balance
98% H₂SO₄ 1,020.41 kg/MT LABSA Derived from 1.500 / 1.470 source mass balance
Added process water 170.07 kg/MT LABSA Derived from 0.250 / 1.470 source mass balance
Diluted acid by-product 870.75 kg/MT LABSA Derived from 1.280 / 1.470 source mass balance
LAB monthly figure ~1,224.5 MT/month equivalent Derived from annual mass-balance requirement; source also reports 1,300 MT/month, which should be reconciled with procurement records
H₂SO₄ monthly figure ~1,836.8 MT/month equivalent Derived from annual mass-balance requirement; source also reports 2,000 MT/month, which should be reconciled with procurement records
Electricity 100 kVA Used because the source contains both 100 HP and 100 kVA
Land 2,695.09 m² itemized total Gross-area discrepancy with 9,254 m² requires survey/title verification
Important: This calculator is a planning/pre-feasibility tool. It does not replace detailed process design, equipment sizing, HAZOP, material compatibility review, environmental approval, electrical load study, laboratory validation, or statutory engineering certification.

Engineering Notes

Process terminology

The calculator uses Linear Alkyl Benzene Sulphonic Acid (LABSA) as the product name. The source document contains variant/incorrect terminology in some places; the standard product name is used here for consistency.

By-product terminology

The source uses both “spent acid” and “diluted sulphuric acid 75–80%”. This calculator labels the stream Diluted H₂SO₄ / spent-acid stream so that the original report terminology is not hidden.

Process-time discrepancies

The source contains different reaction/separation time statements. Those values are not used as hidden assumptions in this calculator. Final residence time and separator sizing should come from process/vendor design.

Environmental and regulatory use

Environmental statements such as “Zero Effluent Discharge” and source-reported emission figures should be treated as preliminary claims requiring verification against the final site water balance, equipment selection, monitoring requirements and applicable approvals.

How to use

  1. Enter your target LABSA TPD.
  2. Enter operating days/year.
  3. Adjust the mass-balance coefficients only when you have an approved engineering basis.
  4. Click Calculate.
  5. Review daily, monthly and annual requirements.
  6. Use Print / Save PDF to create a printable calculation sheet.

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.

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.
LABSA Industry Calculator • Based initially on the supplied LABSA 90% pre-feasibility report • All design assumptions should be independently verified.

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.
