Pitch and Stickies Deposition

Problem Summary

Organic contaminants in the papermaking process originate from either natural or synthetic sources. The natural source is predominantly wood pitch while synthetic sources include adhesives and coating binders from secondary fiber or broke. The latter are often referred to as “stickies.” While the majority of these contaminants are screened out of the process, some pass through as colloidal material. Generally, colloidal pitch and stickies do not cause too many problems. However, under conditions of shear or temperature shock, these contaminants can deposit throughout the stock prep system and headbox, on forming fabrics, press rolls, and uhle boxes, and on other machine surfaces. More often than not, such deposition negatively impacts paper machine productivity and/or the quality of the finished paper by causing holes, breaks, and sheet defects.

Recommended Solution

Three quite different chemical methods are commonly used in the paper industry to control pitch and stickies deposition:

Stabilizing the pitch and stickies with a dispersant or surfactant
Reducing the tackiness of the colloidal pitch and stickies using a detackifier or mineral, such as talc
Removing the colloidal pitch and stickies from the system together with the paper using a highly charged cationic polymer

Traditionally, these methods have rarely been combined because this typically provided few additional benefits and the methods have not been complementary. However, Hercules has developed a new technology that combines an amphoteric, surface-active, structured protein with a highly charged cationic polymer. The structured protein is able both to increase the stability and to reduce the tackiness of colloidal contaminants. The real key to the effectiveness of the program, however, is the effect achieved when the structured protein is used together with a cationic polymer to retain the contaminants with the web. This technology, which is marketed by Hercules as Zenix® Detackifier Technology, has been shown to be considerably more effective at reducing or eliminating pitch and stickies deposition than existing chemical control methods.

Key benefits recorded from practical applications of Zenix® Detackifier Technology include:

Eliminated/reduced deposition
Fewer breaks, holes, and sheet defects
Increased paper production
Increased machine efficiency
Decreased downtime for cleaning
Decreased usage of cleaning chemicals

Burj Al Arab

The Burj Al Arab (Arabic: Tower of the Arabs) is a luxury hotel located in Dubai, United Arab Emirates. At 321 m (1,050 ft), it is the second tallest building in the world used exclusively as a hotel. The Burj Al Arab stands on an artificial island 280 m (920 ft) out from Jumeirah beach, and is connected to the mainland by a private curving bridge. It is an iconic structure, designed to symbolize Dubai's urban transformation and to mimic the sail of a boat.

Construction of Burj Al Arab began in 1994. It was built to resemble the sail of a dhow, a type of Arabian vessel. Two "wings" spread in a V to form a vast "mast", while the space between them is enclosed in a massive atrium. The architect Tom Wright said "The client wanted a building that would become an iconic or symbolic statement for Dubai; this is very similar to Sydney with its Opera House, or Paris with the Eiffel Tower. It needed to be a building that would become synonymous with the name of the country."

The architect and engineering consultant for the project was Atkins, the United Kingdom's largest multidisciplinary consultancy. The hotel was built by South African construction contractor Murray & Roberts. The hotel cost US$650 million to build.

Several features of the hotel required complex engineering feats to achieve. The hotel rests on an artificial island constructed 280 m (920 ft) offshore. To secure a foundation, the builders drove 230 40 m (130 ft) long concrete piles into the sand.

Engineers created a surface layer of large rocks, which is circled with a concrete honeycomb pattern, which serves to protect the foundation from erosion. It took three years to reclaim the land from the sea, but less than three years to construct the building itself. The building contains over 70,000 m3 (2,500,000 cu ft) of concrete and 9,000 tons of steel.

Inside the building, the atrium is 180 m (590 ft) tall.

Burj Al Arab promotes itself as the world's only "7-star" property, a designation considered by travel professionals to be hyperbole. All major travel guides and hotel rating systems have a 5-star maximum, which some hotels attempt to out-do by ascribing themselves "6-star" status. Yet according to the Burj Al Arab's official site, the hotel is a "5-star deluxe hotel". It is the world's tallest structure with a membrane facade and the world's second tallest hotel (not including buildings with mixed use) and was the first 5-star hotel to surpass 305 m (1,000 ft) in height.


The hotel is managed by the Jumeirah Group. Despite its size, the Burj Al Arab holds only 28 double-storey floors which accommodate 202 bedroom suites. The smallest suite occupies an area of 169 m2 (1,820 sq ft), the largest covers 780 m2 (8,400 sq ft). It is one of the most expensive hotels in the world. The cost of staying in a suite begins at US$1,000 per night; the Royal Suite is the most expensive, at US$28,000 per night.

Suites feature design details that juxtapose east and west. White Tuscan columns and a spiral staircase covered in marble with a wrought-iron gold leaf railing show influence from classicism and art nouveau. Spa-like bathrooms are accented by mosaic tile patterns on the floors and walls, with Arabian-influenced geometries, which are also found elsewhere in the building.

One of its restaurants, Al Muntaha (Arabic meaning "Highest" or "Ultimate"), is located 200 metres (660 ft) above the Persian Gulf, offering a view of Dubai. It is supported by a full cantilever that extends 27 metres (89 ft) from either side of the mast, and is accessed by a panoramic elevator. The main chef there, Edah Semaj Leachim, was awarded Chef of the Year 2006 and also owns the restaurant, in accordance with the Burj Al Arab hotel.
Another restaurant, the Al Mahara (Arabic meaning "The Oyster"), which is accessed via a simulated submarine voyage, features a large seawater aquarium, holding roughly 990,000 litres (35,000 cu ft) of water. The tank, made of acrylic glass in order to withstand the water pressure, is about 18 centimetres (7.1 in) thick. The restaurant was also voted among the top ten best restaurants of the world by Condé Nast Traveler.

Emerald Bay

Almost no crowd, some of the best snorkeling I found on the island, free umbrellas and chairs, and you can bring beer/refreshments from your own refrigerator without cost. We ate elsewhere everday. This beach is the perfect place to get away from the crowds due to its secluded location. This very private and sandy beach has very calm waters and is perfect for swimming. The Beach typically attracts a family-oriented crowd during the summertime, deviating from more hectic beach vacation destinations. The beach does not contain a boardwalk and the night life is limited to a few quality bars.
A favorite with visitors and a popular stop on island tour itineraries, the beach gets crowded when multiple cruise ships are in port. Coki is equally popular with residents for picnics and parties so its common to find a crowd on Sundays and holidays. Even so, the beach was never very crowded and there were always plenty of available chairs. We also saw several weddings taking place on the beach during our stay this year. While some like a crowded beach with plenty of people and activity, others would just like to relax in a quiet spot.
Designated an underwater park in 1994, Emerald Bay is truly an amazing place to visit. First, the garden’s reflecting pools were obliterated because they leaked into the parking garage below, damaging the paint on some cars. Never mind that the pools were an integral part of the design, created by Dan Kiley, who is known as the dean of American landscape architecture in international cultural circles.
It is your responsibility to survey the cove, account for the weather, waves and tides before visiting. I haven’t surveyed the whole cove. The secluded cove has consistently calm waters and great snorkeling for beginner, intermediate or advanced aquanauts. There is plenty of action nearby but the location assures a stress free and restful holiday.
Snorkeling is good along the rocky coastline on the right side. Palm trees are scattered along the shoreline giving the beach a very tropical feel; hammocks suspended between the palms help to enhance the atmosphere.

There are some good waves there in winter, but you can’t expect any waves in summer. It’s a beach break and usually smaller than the other beaches. In winter people bicycle around here but in summer with 96 degrees and not enough breeze air conditioned motor vehicles are more to summer residents taste. Even with my folding chair over my shoulder, a bottle of water and book I don’t find the hundred yard stroll overwhelming on the hottest of days.

In the evenings, visitors may hop on the summer trolley, which stops in front of the cottage every 20 to 30 minutes, and enjoy dinner downtown. Or they can stay in, put their feet up, and watch the magnificent sunset over the sea.

Beautiful Mount From Indonesia

Bromo is a popular tourist destination in East Java.
The volcano is noted for its spectacular sunrises, and majestic views across to Semeru volcano in the south.
Two people were killled during an eruption of Bromo on 8th June 2004.
Bromo is the only active crater in a caldera which contains seven eruptive centres.
In 1838 the crater was filled with a lake.
The Ngadisari caldera at the NE end of the complex formed about 150,000 years ago and is now drained through the Sapikerep Valley. The most recent of the Tengger calderas is the 9 x 10 km wide Sandsea Caldera at the SW end of the complex, which formed incrementally during the late Pleistocene and early Holocene. An overlapping cluster of post-caldera cones was constructed on the floor of the Sandsea Caldera within the last several thousand years. The youngest of these is Bromo, one of Java’s most active and most frequently visited volcanoes.
Volcano type : Stratovolcano
Location : East Java, Indonesia, 7.942°S / 112.95°E
Summit elevation 2329 m (7,641 ft)
Last eruptions 1804, 1815, 1820, 1822, 1825, 1829, 1830, 1835, 1842, 1843, 1844, 1856, 1857, 1858, 1858, 1859, 1860, 1865, 1865, 1866, 1867-68, 1877, 1885, 1885-86, 1886, 1886-87, 1888(?), 1890, 1893, 1896, 1906-07, 1907, 1907-08, 1909, 1910, 1915-16, 1921, 1922, 1928, 1930, 1935, 1939, 1940, 1948, 1950, 1955, 1956, 1972, 1980, 1983(?), 1983, 1984, 1995 (March-May), 1995 (Sep-Dec), 2000 (Nov)-20001 (Jan), 2004 (June)
