Design of one Operation Unit - Essay Example The technology currently accounts for more than 20% of air separations. In cryogenic distillation applied in this design, air is liquefied, and then fractionally distilled, separating the air into its constituents primarily nitrogen, oxygen and argon. This is a complex process that is the most common and efficient method of large scale oxygen production. It is also the most efficient method of storing oxygen. Liquid oxygen storage is six to eight times more efficient than high pressure cylinders. The complexities and cool down requirements highly favour continuously operating production plants; this is not usually the mode of operation for field medical facilities. Liquid oxygen can be stored, but there is a loss rate that is dependent on the size of the container, the amount of liquid oxygen in the container, and the ambient temperature. Liquid oxygen cannot be stored for long term use. It is a simple matter to safely fill high pressure oxygen cylinders using liquid oxygen. Cryogeni c air separation is currently the most efficient and cost-effective technology for producing large quantities of oxygen, nitrogen, and argon as gaseous or liquid products. An air separation unit using a conventional, multi-column cryogenic distillation process produces oxygen from compressed air at high recoveries and purities. Cryogenic technology can also produce high-purity nitrogen as a useful by product stream at relatively low incremental cost. In addition, liquid argon, liquid oxygen, and liquid nitrogen can be added to the product slate for stored product backup or byproduct sales at low incremental capital and power costs. Capacity and product specification The designed system comprises of 3 columns with a length of 1 meter each. Its ID is 3cm. The system is equipped with an automated control system for regulation of each cycle’s time to monitor and record rate of flow, system pressure, and temperatures of the columns. The designed system can be applied to an extensi ve range of absorbents and pressures in facilitating the adsorption process. The targeted optimal rate of flow of oxygen to be produce by the system is 80 lit/min. design specifications are illustrated in the tables below, Capacity table: Theoretical Model Fix layer and dynamic regime adsorption is often characterized by continuous fluid flow phase going via an adsorbent layer within a time variable process (Nexant Inc., 2010). This is theoretically represented in the diagram below: At the process start, free adsorbent layer volume is considered as filled up with a given component A which cannot be absorbed and further, the solid is â€Å"clean†, and does not have any absorbing component B. Other assumptions made are that the gas is ideal; the absorbent layer has constant temperature, the section has constant speed, and that there is an insignificant pressure drop in the layer. This process is represented in a mathematical model which incorporates multiple equations referring to adsorbed component in volume element of height, fluid phase, and solid and the balance equation. These equations are illustrated hereafter, Product stands for mass transfer coefficient per absorbent layer’s unit volume. The first two equations can be simplified using a modified time variable as follows, The equations can be solved simoultaneously with knowledge of limit conditions: At the start, adsorbed component concentration is zero at any point in the adsorption

Report - Competing through Marketing Assignment

Report - Competing through Marketing - Assignment Example Marketing planning is a strategic process used by organizations to predict the future environment of the business for the sole aim of strategizing on the appropriate strategy for maximizing the full potential of the existing and future market. In organizations, market planning helps in allocation of resources, identification of the strengths and weaknesses and provides advance warning. Overall, marketing in organizations revolves around expanding the market, increasing the organization’s profit, exhausting resources, and targeting the right market (Lecture 1 & 2). Trends in banking and financial services Globalization According to Cummins and Venard (2007), different supranational agencies which include the World Bank and World Trade Organization have been major contributors in promoting globalization to the entire world, with a specific impact been focused to Asia. A good example in respect to this is in 2001 when the Chinese government was signatory of the WTO; there were cr ucial commitments made by the government in terms of liberalizing insurance industry. A new stage was hence created for the development of the insurance sector and opening of the market was enhanced instead of the previous restricted market (Padmalatha, 2011). Moreover, globalization ensures the ease of financial firms accessing the market beyond the borders of their country of origin. Globalization also ensures future penetration of foreign firms to a foreign market (Cummins and Venard, 2007, p.19). Private insurance In the past, majority of countries relied on government programs and insurance companies but of late, the trend has changed as they are relying on private insurance companies that have become dominant in the economy. Moreover, government insurance companies have diminished in time due to wave of privatization (Cummins and Venard, 2007, p.19). New technology Financial firms have witnessed advancement in new technology over the past few years. This has increased and enha nced marketing of new products in a rapid manner as compared to the past. New technology has brought with it an introduction to new sophisticated products. In insurance industry, for instance, there is an introduction of universal life insurance, which can be termed as a change facilitated by development in communication and computer technologies (Cummins and Venard, 2007, p.19). Differences between building societies and banks Building societies are mutual societies, which mean that, they are owned by members. These members either have taken a mortgage with the society or have invested with them. On the other hand, banks may not possess shareholders who earn dividends from profits earned; instead, the profit earned in banks is normally ploughed back into the firm. Basically, the difference between the two is based on their nature of lending (Boleat, 1985, p.4). In terms of raising money, building societies normally offer mortgage loans when purchasing a house. In this case, the hou se acts as the security against the received loan. In addition to this, building societies can transact loans, which are unsecured. These loans mainly
