Data Reconciliation and Validation

RAGE is a general purpose data reconciliation and validation software developed in collaboration with EIL R&D center. "RAGE" can handle a wide range of process units such as mixers, separators, splitters, heat exchangers, two-phase separators, tanks, etc. that are extensively used in chemical and mineral processing plants. It has been widely tested on industrial processes and is currently in use at EIL R&D center, BPCL and HPCL.

PC Based Hazard Analysis (HAZOP and DOW Index)

HAZOP and DOW index are routinely used worldwide to assess process hazards and operability of plants. This package can be used for such an analysis. Another software for probit equations, pool fire, fire ball, explosion, gas dispersion is under development.

Simulation of Distillation and Absorption Columns

The simulator is based on the Naphtali-Sandhohm method. It exploits the sparsity of the inner blocks of the Jacobian matrix. The elements of the Jacobian matrix are evaluated using analytical methods. The non-ideal behavior of the systems are accounted for by using the Wilson or UNIQUE equations of state. The multi-component efficiencies required for rigorous simulation are estimated using the Stefan-Maxwell approach to mass transfer. Entrainment is also taken into account.

Recovery Of Water And Inorganic Chemicals From Kraft Black Liquor

A process has been developed to recover and recycle water alongwith inorganic chemicals from kraft black liquor (pulp and paper industry effluent) without destroying organics (conventional process evaporates water and destroys organics and thus creates pollution). The developed process is based on membrane technology and is ready for commercialization.

Adsorbtative Separation System For Gaseous and Liquid Mixtures

Adsorbers are used for the separation of gaseous and liquid mixtures. Due to difficulties in handling of solids, these are run as batch or as simulated moving bed adsorbers. With aid of moving port system, true continuous, counter current mode of operation in a fixed bed has been achieved. It can be used for separation of bulk gas and liquid mixtures.Further R&D work is in progress which will eventually lead to commercialization.
