Chemical processes involve the transfer of reactants to a reaction zone, chemical reactions using unit processes, and separation of products from the reaction zone using unit operations. Unit operations are physical separation methods like distillation, absorption, and filtration. Key unit processes are chemical conversions like nitration, halogenation, oxidation, and polymerization that produce useful products. As an example, the document discusses the multi-step nitration process to produce trinitrotoluene (TNT) explosive from toluene.

Internship Report of Unicol Mirpurkhas (Ethanol Distillery)Talal Khan
This is a brief report of Ethanol Distillery situated in Mirpurkhas, Sindh, Pakistan.
It defines the Distillation Process, CO2 Liquification Process, Formation of Bio Gas from Molasses, Water Purification Plant, and Boiler working in Unicol Distillery.
This project is focused on existing technologies that could be applied to the processing of algae
biomass. Also cover the design of the process in which prototype of Distillation column, Heat
exchangers and Reactor will design. Project will also cover the socio-economic impacts
(Environmental considerations; Economic considerations and Energy considerations). For testing
our process model, the algal biodiesel will be produced on lab scale to understand the
consequences, requirements and difficulties.
This presentation details out all the process in an Oil Refinery. If you are looking to have a hawk eye view of all the oil refinery process, this presentation will set you on.
Simple explained.
Application of Levapor Carriers for the treatment of Contract Agro Chemicals manufacturer producing a wide Range of Pesticides and Herbicides. The effluent contained very high amount of active pesticides and herbicides with high salinity and TKN. A combination of Advanced Oxidation Process -- Anaerobic Treatment --- Levapor carriers based MBBR/IFAS Reactor provided stable nitrification of toxic effluent generating from Agro Chemicals Industry
