“…Different rate-based models have been developed for TCM in the Master Thesis works of Larsen (2014), Desvignes (2015) and Saetre (2016). The gCCS program has been used for dynamic simulations at TCM (Bui et al, 2020).…”

The main purpose of this work has been to fit simulated models to performance data from Test Centre Mongstad (TCM), and evaluate whether fitted parameters for one scenario (a set of experimental data at specified conditions) give reasonable predictions at other conditions. Five scenarios from the amine based CO2 absorption process at TCM have been simulated in a rate-based model in Aspen Plus and an equilibrium based model in Aspen HYSYS and Aspen Plus. It was evaluated whether a fitted interfacial area (for the ratebased model) or an EM-profile (Murphree efficiency on each of 24 stages for the equilibrium based model) gave a good prediction of CO2 removal rate and temperature profile for other conditions. An indication of the predictive performance of the rate-based model is that the interfacial area fitted to the different scenarios had to be varied between 0.29 and 1.0 to obtain the experimental CO2 removal efficiency. Using a specific EM-profile was able to predict both the CO2 removal and the temperature profile for all the scenarios reasonably well. An EM-factor multiplying all the EM values in an EM-profile from another scenario was fitted to values between 0.60 and 1.02 for all the scenarios.

“…The results in Montañés et al [34] showed that following a perturbation, the system took approximately 1 hour to reach steady-state. Bui et al [37] reported three flexible operating scenarios at the TCM capture facility, accompanied with dynamic modelling. The study found the stabilisation time (to allow complete solvent circulation and homogenous solvent compositions) is a minimum of three hours.…”

“…Also, the demonstration scale plant took as long as 114 minutes to transition to new operating conditions following a change in one or more of the main process parameters. This is known as the transition time, and is difficult to incorporate into process models, and Bui et al [37] concludes further improvements in the dynamic response of PCC models is required.…”

“…The CO2 capture rate is the percentage of CO2 removed from the flue gas. Bui et al [37] highlights two potential ways to calculate the reboiler duty, where the energy supplied to the reboiler is divided by either the CO2 product flow post-stripping or the difference between the flue gas inlet and clean gas outlet CO2 flowrates. The energy supplied to the reboiler is the difference between the enthalpy of the inlet utility steam, and saturation enthalpy of the outlet condensed steam [53].…”

“…The flue gas flowrate is 33.80 kg/s or 104,530 Sm 3 /h, similar in scale to the TCM capture plant which can process 60,000 Sm 3 /h of flue gas. The TCM plant absorber packing height is 24m with a column cross sectional area of 3.55x2m, the stripping column is smaller with a packing height of 8m and a diameter of 1.33m [37]. The demonstration facility also incorperates a solvent crossover heatexchanger with an area of 308m 2 [63].…”

A modified electrolyte non‐random two‐liquid model with analytical expression for excess enthalpy: Application to theMEA‐H₂O‐CO₂system

Accurate thermodynamic properties of electrolyte systems are critical for the design and operation of many chemical processes. A comprehensive description of the thermodynamic framework for multielectrolyte mixed solvent systems is presented, where the parameter structure of the symmetric electrolyte‐non‐random two liquid (e‐NRTL) model is reformulated and a thermodynamically consistent and analytically derived formulation for the excess enthalpy is developed from the e‐NRTL model. The refined parameter structure of the e‐NRTL model avoids numerical singularities of the analytical formulation for the excess enthalpy in the absence of ionic species and extends the derived excess enthalpy formulation to non‐electrolyte systems. The thermodynamic framework is demonstrated for the MEA‐H2O‐CO2 case study using experimental data on thermodynamic quantities for the binary MEA‐H2O system and the ternary MEA‐H2O‐CO2 system. The model is implemented in Pyomo and will be available for release in the Institute for the Design of Advanced Energy Systems (IDAES) computational platform.
