Design and fabrication of a portable integrated system for the management and treatment of oil-based drilling fluid waste by combining mechanical processes (separation, dewatering, and filter pressing) with bioremediation using a modified vermicomposting reactor, configured as a mobile operational unit deployable at drilling rig sites, with the aim of achieving >90% hydrocarbon reduction, minimizing waste volume, and recovering water.
Variability in waste composition (solids content, TPH, viscosity, salts, and inhibitory additives); design of an integrated hybrid process coordinating mechanical and biological treatment stages; maintenance of optimal conditions in the vermicomposting reactor (moisture, temperature, aerobic conditions, feed ratio, and earthworm and microbial activity); selection of species resistant to petroleum compounds and salinity; design of tanks and pumps for non-Newtonian fluids containing suspended solids; prevention of filter press clogging; integration of equipment within a mobile unit under space and weight constraints; and continuous monitoring of TPH, COD, pH, moisture, and solids content.
Baseline studies to characterize waste properties and identify key process parameters; conceptual process design covering pretreatment, bioremediation, dewatering, and final separation stages; development of a modified vermicomposting bioreactor; design of buffer tanks with and without mixers; selection of suitable pumps; design of the dewatering and filter press units; layout design of the mobile operational unit; design of electrical, control, and instrumentation systems; and establishment of laboratory infrastructure for performance monitoring.
A portable operational pilot system comprising receiving, homogenization, vermicomposting bioreactor, dewatering, and filter press sections; indigenous technical know-how for bioreactor design and the integrated treatment process; operation and maintenance procedures; performance evaluation based on pollutant reduction, bed stability, dewatering efficiency, and waste volume reduction; and final technical documentation, including engineering drawings, test reports, laboratory results, and an industrial scale-up feasibility assessment.

Design and development of magnetoactive nanoceramic coatings to inhibit the nucleation and growth of coke deposits in process equipment used in bitumen-producing refineries. Through surface engineering, these coatings prevent the initial adhesion of coke, thereby enhancing equipment efficiency and extending its service life.

Design and manufacture of an industrial turbo-compressor to supply combustion chamber air and plant compressed air by utilizing the heat generated from the combustion of excess gas. The key innovation is the elimination of the power turbine rotor and the splitting of the hot gas flow upstream of the gas-generator turbine inlet, which reduces costs while increasing aerodynamic loading.
