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.

The source document reports both 100 HP and 100 kVA in different sections. This calculator uses 100 kVA as the preliminary electrical basis; final connected load requires an electrical load study.

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.
