ENGINEERING METHOD
Steady-state and, where required, dynamic simulation; thermodynamic-method selection; assay characterization; column models; reaction or conversion basis; sensitivity and turndown cases.
ENGINEERING TEAM & DIGITAL TOOLCHAIN
Process Simulation & Heat–Material Balance
UNKA ENGINEERING uses process simulation to translate feed analysis and product targets into a consistent heat and material balance. The model establishes stream conditions, separation requirements, equipment duties and utility loads for the approved operating cases.
TYPICAL SOFTWARE / TOOL CLASS
Typical project-selected platforms may include Aspen HYSYS, Aspen Plus, CHEMCAD or PRO/II-class process simulators; specialist calculations and validated spreadsheets support defined duties.
CRITICAL INPUTS
Representative feed assay/composition, operating targets, product specifications, pressure profile, utilities and recycles.
ENGINEERING DELIVERABLES
Simulation basis, stream table, heat and material balance, utility balance, equipment duty list, PFD inputs, sensitivity cases and model archive.
VERIFICATION & QUALITY CONTROL
Property-method review, closure checks, independent balance verification, comparison with laboratory/licensor/vendor data and controlled model revision.
APPLICATIONS & PROJECT INTERFACE
CDU/VDU, fractionation, hydrotreating interfaces, solvent recovery, alcohol distillation, utility and revamp/debottleneck studies.
STANDARDS & TOOLCHAIN NOTE
Software is selected per project scope, client requirement, interoperability and licensed availability; naming a tool class does not imply that every project uses every product.
CONTRACTUAL CODE BASIS
