We also undertake process engineering jobs which focuses on the design, operation, control, and optimization of chemical, physical, and biological processes. Process engineering encompasses a vast range of industries, such as chemical, petrochemical, agriculture, mineral processing, advanced material, food, textile, pharmaceutical, and biotechnological industries.
Process engineering involves translating the needs of the customer into production facilities that convert "raw materials" into value-added components prior to construction, the design work of process engineering begins with a "block diagram" showing raw materials and the transformations/unit operations desired. The design work then progresses to a Process flow diagram (PFD) where material flow paths, storage equipment (such as tanks and silos), transformations/Unit Operations (such as distillation columns, receiver/head tanks, mixing, separations, pumping, etc.) and flowrates are specified, as well as a list of all pipes and conveyors and their contents, material properties such as density, viscosity, particle size distribution, flow rates, pressures, temperatures, and materials of construction for the piping and unit operations. The process flow diagram is then used to develop a Piping and instrumentation diagram (P&ID) which includes pipe and conveyor sizing information to address the desired flowrates, process controls (such as tank level indications, material flow meters, weighing devices, motor speed controls, temperature and pressure indicators/ controllers, etc.). The P&ID is then used as a basis of design for developing the "system operation guide" or "functional design specification" which outlines the operation of the process. From the "P&ID", a proposed layout of the process can be shown from an overhead view and a side view, and other engineering disciplines are involved such as civil engineers for site work , foundation design, concrete slab design work, structural steel to support the equipment, etc. All previous work is directed toward defining the scope of the project, then developing a cost estimate to get the design installed, and a schedule to communicate the timing needs for engineering, procurement, fabrication, installation, commissioning, startup, and ongoing production of the process. Depending on the needed accuracy of the cost estimate and schedule that is required, several iterations of designs are generally provided to customers or stakeholders who feedback their requirements and the process engineer incorporates these additional instructions and wants into the overall design and additional cost estimates and Schedules are developed for funding approval. Following funding approval, the project is executed via project management.
Solvent recovery systems for removing solvent's from" water steam, caustic recovery plants for recovery of caustic in textile industry and concentration of caustic in various other industries at the best operating cost and with the best technology. We also undertake various technological jobs for engineering, design, manufacture and supply.
