Design of chemical and physical process plants

Corn Kraft Paper Corporation produces an export quality product that is made of corn husk. A company that is environmentally sustainable for a brighter, safer, and, healthier future. A company that doesn't focuses only for the economic growth but has ethical responsibility socially and environmentally. The company produces kraft paper as a primary packaging material for different industrial application. He company produces different cuts of product depending on the orders specification. A quality product that is scientifically proven to be more tougher and durable compared to other ordinary kraft paper company, most specially that it is sustainable. The company is located at Lingayen, Pangasinan Philippines, an agricultural province where the main raw material which is the corn husk can be found. The company produces kraft paper for local and international use.

Aptitud es la capacidad para hacer algo. Algunas aptitudes son innatas, mientras que otras se desarrollan con el tiempo y la experiencia. No es lo mismo que actitud, ya que ésta última consiste en estar dispuesto a hacer algo, y por tanto depende del estado de ánimo. Un ingeniero químico desarrolla las siguientes aptitudes a lo largo de su carrera: a. Dimensionamiento de equipos  Operaciones unitarias  Fenómenos de transporte (transferencia de masa, calor y momentum)  Ingeniería de la reacción b. Diseño de plantas  Diagramas  Lectura de planos  Distribución en planta  Normas, procedimientos c. Diseño de procesos  Balances de masa y energía  Simulación  Optimización  Control de proceso d. Diseño de productos, que conjuntamente con el diseño de productos, corresponde al área de investigación  Estadística  Diseño experimental

A guide to pressure vessel designer. The lecture was delivered as a part of safety week celebration at "Essar"  Surat for the  students of Chemical Engineering and  Project equipment design people  who are looking for the  over all view of design parameters available in this field.

This is the bullet version of notes made personally by me. This version is unedited if you intended to leave your own notes besides the ones I have made . Check out the edited version for explanation on my notes which I referred from the Turton book.

This paper covers the research carried out by the authors on the conversion of post-consumer polyethylene terephthalate (PET) into a thermosetting polyester resin. Glycolysis and hydrolysisglycolysis were chemical recycling techniques used in the depolymerisation of PET wastes to reprocess able monomers and oligomers. The experiment was performed on PET sourced from soft drink bottles. The flakes were glycolysed using Diethylene glycol and Polyethylene terephthalate of various w/w ratios at various temperatures and reaction times, with potassium acetate (1% w/w of the total raw materials) as catalyst. For hydrolysis-glycolysis method, Diethylene glycol/ water/ polyethylene terephthalate w/w ratio at various operating temperatures and residence times were used. The w/w ratios were carefully chosen to know the trend of the yield increment at specific operating conditions. Also, water was used as hydrolysis medium in the case of hydrolysis-glycolysis to avert equipment corrosion and pollution, and is very cheap. The products obtained were purified using methanol and sun dried. From physical and chemical properties analyzed (density, refractive index, viscosity, melting point, freezing point, boiling point, acidity number, hydroxyl number and molecular weight) and a Fourier transform infrared test conducted, it was found that the glycolysed products consisted mainly of the monomers “Bis (hydroxyethylene) terephthalate (BHET)”, and oligomers because of the excess Diethylene glycol used that resulted in two hydroxyl end-groups, that is, mixtures of oligoesters diols were formed. It can be used to re-synthesis ethylene terephthalate or co-polymers. Recycling of PET does not only serve as a partial solution to the solid-waste problem, but serve as a source of raw material to some industries and also contribute to the conservation of raw petrochemical products and energy which is of high importance due to high cost of energy in the World of today.

The Process Design discipline is greatly advanced by having better property data, sophisticated computer programs and a growing base of experience. But a high quality process design job can be only obtained effectively if the designer is given a clear, well-defined starting point.
It is therefore very important that both the operating company and the consultant work together so that al plant changes and modifications are designed and implemented in a way that retains safety integrity and meets the project specifications and expectations.
