Pulp, paper and board

The pulp and paper industry comprises companies that use wood as raw material and produce pulp , paper , paperboard and other cellulose-based products. The pulp is fed to a paper machine where it is formed as a paper web and the water is removed from it by pressing and drying. Pressing the sheet removes the water by force. Once the water is forced from the sheet, a special kind of felt, which is not to be confused with the traditional one, is used to collect the water. Whereas, when making paper by hand, a blotter sheet is used instead. Drying involves using air or heat to remove water from the paper sheets.

ANDRITZ PULP & PAPER

This four volume set covers the entire spectrum of pulp and paper chemistry and technology from starting material to processes and products including market demands. This work is essential for all students of wood science and a useful reference for those working in the pulp and paper industry or on the chemistry of renewable resources. Volume 2 focuses on creating an understanding of the chemical and technical processes involved in the production of pulp. The work treats wood handling, i. EN English Deutsch.

The new design includes the latest bagless technology, which is well-proven in over 65 installations to date. The upgraded PrimeFilter D has been well-received already — 15 units have been started up and more orders are being received from leading papermakers. To avoid unplanned plant shutdowns, it is important to know at an early stage when vital components need to be replaced or maintained. Condition monitoring enables operators to work proactively and keep shutdown time to a minimum. The mill has recently undergone a number of improvements including the implementation of a smart bleaching system from ANDRITZ that is making a real difference when it comes to chemical consumption. He joined ANDRITZ about 13 years ago as a design engineer for tissue and paper machines providing a product development focus early on. Your technology and service partner for the production of pulp, paper, tissue, and board — and in the generation of power from renewable resources.


Results Both issues have been addressed by targeting pulp and paper industry processes for application in bioethanol production.


Technological Transformation in the Global Pulp and Paper Industry 1800–2018

Papermaking is thought to have originated in China in about A. Although mechanization increased over the intervening years, batch production methods and agricultural fibre sources remained in use until the s. Continuous papermaking machines were patented at the turn of that century. Methods for pulping wood, a more abundant fibre source than rags and grasses, were developed between and , and included mechanical abrasion as well as the soda, sulphite, and sulphate kraft chemical methods.

It deals with the relationships between technology transfer, technology leadership, raw material dependence, and product variety on a global scale. The study itemises the main drivers in technology transfer that affected this process, including the availability of technology, knowledge, investments and raw materials on the one hand, and demand characteristics on the other hand, within regional, national and transnational organisational frameworks. The volume is intended as a basic introduction to the history of papermaking technology, and it is aimed at students and teachers as course material and as a handbook for professionals working in either industry, research centres or universities.

Comparative Perspectives

 Ужас, правда. Беккер кивнул. - Ты же сказала, что не колешься. Девушка засмеялась: - Это же чудо-маркер. Я чуть кожу не содрала, пытаясь его стереть. Да и краска вонючая. Беккер посмотрел внимательнее.

Тут все без обмана. Он стоит десять раз по двадцать миллионов. - Увы, - сказал Нуматака, которому уже наскучило играть, - мы оба знаем, что Танкадо этого так не оставит. Подумайте о юридических последствиях. Звонивший выдержал зловещую паузу. - А что, если мистер Танкадо перестанет быть фактором, который следует принимать во внимание. Нуматака чуть не расхохотался, но в голосе звонившего слышалась подозрительная решимость.

Он еще раз сжал его руку, но тут наконец подбежала медсестра. Она вцепилась Беккеру в плечо, заставив его подняться - как раз в тот момент, когда губы старика шевельнулись. Единственное сорвавшееся с них слово фактически не было произнесено. Оно напоминало беззвучный выдох-далекое чувственное воспоминание. - Капля Росы… Крик медсестры гнал его прочь. Капля Росы.

Директор старался в такие дела не вмешиваться, и это делало его уязвимым, а Мидж постоянно нервничала по этому поводу.

Первая попытка закончилась неудачей. Нахмурившись, Беккер набрал второй номер. И на другом конце сразу же сняли трубку.
