Book Description
Project Report from the year 2016 in the subject Chemistry - Other, , language: English, abstract: This is a part two of the Advance Process design project. Part one was a group project in which we carried out a feasibility study of Methanol to Olefin (MTO) plant. The plant is an extension of an existing Coal-chemical complex in China, which produces 1,000,000 tonnes of methanol from coal each year. In order to become more competitive in the market, we studied alternative routes of MTO process and designed the most efficient, least pollutant and safest plant. The aim of this individual project is to cover a detailed design of the C2 splitter distillation column which is the final step in the MTO process where ethylene and ethane are separated. As ethylene is one of the most popular petrochemical product and the demand for the product is continuously increasing each year. Therefore, to meet the customers demand the column was designed with 99.4% purity. For the initial design calculation, the operating pressure of the column was chosen as 24bar. The diameter of the column was calculated to be around 1.66m for the stripping section, which was suitable for the sieve plate design. Using the AlChE method, the plate overall efficiency was obtained as 73%, which was in the range of the distillation column efficiencies, by using the plate efficiency the actual number of stages was obtained, 53 stages, with an overall height of the column as 35m. At 24bar the condenser duty of the column was calculated to be 2.66MW and reboiler duty 2.43MW. The design optimisation shows that as the pressure of the column increases, the capital cost of the column also increases due to the increase in a number of actual stages and the reflux ratio, mean taller and thicker column wall, will be required to meet the right specification and to handle the high pressure of the column. But, with the increasing pressure, the energy cost of the column decreases, as less energy will be required to condense the overhead vapour. The capital cost of the column outweighs the energy cost of the column. Therefore, the column total cost increases with the increase in column pressure. The optimum pressure, for the C2 splitter column, was chosen as 10bar. The reason being, low reflux ratio and less number of stages will be required, meaning the less capital cost of the column.

Book Description
This text explains the concepts behind process design. It uses a case study approach, guiding readers through realistic design problems, and referring back to these cases at the end of each chapter. Throughout, the author uses shortcut techniques that allow engineers to obtain the whole focus for a design in a very short period (generally less than two days).

Book Description
This book, written and edited by leading authorities from academia and industrial groups, covers both preventive- and curative-zeolite-based technologies in the field of chemical processing.The opening chapter presents the state of the art in zeolite science. The two subsequent chapters summarize the chemistries involved in the processes and the constraints imposed on the catalyst/adsorbent. Three major areas are covered: oil refining, petrochemicals and fine chemicals. A chapter on the (curative) use of zeolites in pollution abatement completes this overview.In the area of oil refining, a general lecture sets the scene for present and future challenges. It is followed by in-depth case studies involving FCC, hydrocracking and light naphtha isomerization. Also, an entire chapter is devoted to the often-overlooked subject of base oils.In the area of petrochemicals, the processing of aromatics and olefins is described and special attention is paid to the synergy between catalysis and separation on molecular sieves.

Book Description
The chapters of this book are based upon lectures presented at the NATO Advanced Study Institute on Membrane Processes in Separation and Purification (March 21 - April 2, 1993, Curia, Portugal), organized as a successor and update to a similar Institute that took place 10 years ago (p.M.Bungay, H.K. Lonsdale, M.N. de Pinho (Eds.): Synthetic Membranes: Science, Engineering and Applications, NATO ASI Series, Reidel, Dordrecht, 1986). The decade between the two NATO Institutes witnesses the transition from individually researched membrane processes to an applied and established membrane separation technology, as is reflected by the contents of the corresponding proceeding volumes. By and large, the first volume presents itself as a textbook on membrane processes, still valid, while the present volume focuses on areas of separation need as amenable to membrane processing: Biotechnology and Environmental Technology. Accordingly, the contributions to this volume are grouped into "Membranes in Biotechnology" (11 papers), "Membranes in Environmental Technology" (6 papers), and "New Concepts" (4 papers). This is followed by one contribution each on "Energy Requirements" and "Education", i.e., membrane processes within an academic curriculum. The book thus amounts to a state of the art of applied membrane processing and may well augment the more fundamental approach of its predecessor.
