This document provides an introduction to drying processes. It discusses how drying is the final removal of water in manufacturing and explains why drying is important, such as reducing transportation costs and providing stable material properties. The general principles of drying involve exposing a material to air until an equilibrium moisture content is reached. There are different forms of moisture and rates of drying must remove both surface and internal moisture. Common drying methods include natural air drying, supercritical drying with superheated steam, and freeze drying. Drying has many industrial applications in industries like food, pharmaceuticals, paper, and chemicals.

A multiple-effect evaporator, as defined in chemical engineering, is an apparatus for efficiently using the heat from steam to evaporate water.[1] In a multiple-effect evaporator, water is boiled in a sequence of vessels, each held at a lower pressure than the last. Because the boiling temperature of water decreases as pressure decreases, the vapor boiled off in one vessel can be used to heat the next, and only the first vessel (at the highest pressure) requires an external source of heat. While in theory, evaporators may be built with an arbitrarily large number of stages, evaporators with more than four stages are rarely practical except in systems where the liquor is the desired product such as in chemical recovery systems where up to seven effects are used.
The multiple-effect evaporator was invented by an African-American inventor and engineer Norbert Rillieux. Although he may have designed the apparatus during the 1820s and constructed a prototype in 1834, he did not build the first industrially practical evaporator until 1845. Originally designed for concentrating sugar in sugar cane juice, it has since become widely used in all industrial applications where large volumes of water must be evaporated, such as salt production and water desalination.
Multiple effect evaporation commonly uses sensible heat in the condensate to preheat liquor to be flashed. In practice the design liquid flow paths can be somewhat complicated in order to extract the most recoverable heat and to obtain the highest evaporation rates from the equipment.
Multiple-effect evaporation plants in sugar beet factories have up to eight effects. Six effect evaporators are common in the recovery of black liquor in the kraft process for making wood pulp.

well this was the presentation on cooling towers that i created for my own presentation. i thought to post it here if it could help any one. just let me know once if it helps any one
A cooling tower is a heat rejection device which extracts waste heat to the atmosphere through the cooling of a water stream to a lower temperature.
A cooling tower is a heat rejection device which extracts waste heat to the atmosphere through the cooling of a water stream to a lower temperature. Cooling towers may either use the evaporation of water to remove process heat and cool the working fluid to near the wet-bulb air temperature or, in the case of closed circuit dry cooling towers, rely solely on air to cool the working fluid to near the dry-bulb air temperature.
Common applications include cooling the circulating water used in oil refineries, petrochemical and other chemical plants, thermal power stations and HVAC systems for cooling buildings. The classification is based on the type of air induction into the tower: the main types of cooling towers are natural draft and induced draft cooling towers.
Cooling towers vary in size from small roof-top units to very large hyperboloid structures (as in the adjacent image) that can be up to 200 metres (660 ft) tall and 100 metres (330 ft) in diameter, or rectangular structures that can be over 40 metres (130 ft) tall and 80 metres (260 ft) long. The hyperboloid cooling towers are often associated with nuclear power plants,[1] although they are also used to some extent in some large chemical and other industrial plants. Although these large towers are very prominent, the vast majority of cooling towers are much smaller, including many units installed on or near buildings to discharge heat from air conditioning.
Boilers are most important part of Chemical Industry. 99 % boilers used in Pakistan Chemical Industries are water tube boilers because of their high efficiency and safety. So we should have clear understanding about the boilers.
Our people are central to us here at Eni โ and their safety, their development and their future are at the heart of everything we do. The creation of a work environment free from discrimination that offers everyone the same opportunities based on the same criteria of merit is a fundamental part of our culture.

No manufactured product plays a more significant role in every area of human activity than
paper and paper products. Its importance in everyday life is obvious from its use in
recording, storage and dissemination of information. Virtually all writing and printing is
done on paper. It is the most widely used wrapping and packaging material, and is
important for structural applications. The uses and applications for pulp and paper
products are virtually limitless. Apart from the products and services that it provides, the
paper and pulp industry is one of the major manufacturing industries in the world
providing employment for vast number of people and contribute to national economy.
The paper making process is essentially a very large dewatering operation where a diluted
solution of pulp suspension with less than 0.5% fibre solid is used. The major sections of a
paper machine consist of: forming section, press section and dryer section. In the forming
section, the fibres present in the diluted pulp and water slurry form paper web through
drainage by gravity and applied suction below the forming fabric. In the press section
additional water in removed by mechanical pressure applied through the nips of a series of
presses or rotating rolls and the wet web is consolidated in this section. Most of the
remaining water is evaporated and inter-fibre binding developed as the paper contacts a
series of steam heated cylinder in the dryer section. Water removal from the wet web to the
final moisture level between 6% and 7% is a critical step of papermaking. Majority of the
functional properties of paper are developed in this section.
In spite of its key role in papermaking, large equipment size, and large capital and operating
costs, drying is arguably the least understood papermaking operation. Books on
papermaking technology generally devote fewer pages to drying than other papermaking
operations such as forming, pressing or calendaring. A similar situation is found in
papermaking courses, in which drying occupies a shorter time than the proportion of space
it takes in a paper machine. Furthermore, a large portion of that time is devoted to the
description of the equipment by its suppliers rather than to its operation by the
papermakers.

www.seribangash.com
A Memorandum of Association (MOA) is a legal document that outlines the fundamental principles and objectives upon which a company operates. It serves as the company's charter or constitution and defines the scope of its activities. Here's a detailed note on the MOA:
Contents of Memorandum of Association:
Name Clause: This clause states the name of the company, which should end with words like "Limited" or "Ltd." for a public limited company and "Private Limited" or "Pvt. Ltd." for a private limited company.
https://seribangash.com/article-of-association-is-legal-doc-of-company/
Registered Office Clause: It specifies the location where the company's registered office is situated. This office is where all official communications and notices are sent.
Objective Clause: This clause delineates the main objectives for which the company is formed. It's important to define these objectives clearly, as the company cannot undertake activities beyond those mentioned in this clause.
www.seribangash.com
Liability Clause: It outlines the extent of liability of the company's members. In the case of companies limited by shares, the liability of members is limited to the amount unpaid on their shares. For companies limited by guarantee, members' liability is limited to the amount they undertake to contribute if the company is wound up.
https://seribangash.com/promotors-is-person-conceived-formation-company/
Capital Clause: This clause specifies the authorized capital of the company, i.e., the maximum amount of share capital the company is authorized to issue. It also mentions the division of this capital into shares and their respective nominal value.
Association Clause: It simply states that the subscribers wish to form a company and agree to become members of it, in accordance with the terms of the MOA.
Importance of Memorandum of Association:
Legal Requirement: The MOA is a legal requirement for the formation of a company. It must be filed with the Registrar of Companies during the incorporation process.
Constitutional Document: It serves as the company's constitutional document, defining its scope, powers, and limitations.
Protection of Members: It protects the interests of the company's members by clearly defining the objectives and limiting their liability.
External Communication: It provides clarity to external parties, such as investors, creditors, and regulatory authorities, regarding the company's objectives and powers.
https://seribangash.com/difference-public-and-private-company-law/
Binding Authority: The company and its members are bound by the provisions of the MOA. Any action taken beyond its scope may be considered ultra vires (beyond the powers) of the company and therefore void.
Amendment of MOA:
While the MOA lays down the company's fundamental principles, it is not entirely immutable. It can be amended, but only under specific circumstances and in compliance with legal procedures. Amendments typically require shareholder

given temperature and humidity the
material will either lose or gain water
until an equilibrium condition is
established.
7. Forms of moisture
Bound moisture
โข This is Water content retained in such
a way that it exert a vapour pressure
than that if free water at same
Free Moisture
โข This is water which is in excess
