North Thailand, January 2019.
TECHLINK installed a new scrubber at the outlet of a hydrochloric acid synthsis column in a large sodium chlorate and chlorine dioxide plant.
This additional scrubber will bring the emissions of hydrogen chloride down from 150 ppm to below 10 ppm, in line with the Government’s regulations, and reduce the ambiant corrosion of the neighbouring assets of the plant.
North of Thailand, September 2018. As part of their effort to comply with the best environmental standards, a major Pulp & Paper company in North Thailand has missionned TECHLINK to expand their storage of hydrochloric acid from 200 m3 to 500 m3, allowing a reduction of the inventory of the more dangerous liquid chlorine.
The project started this month with the erection of two FRP tanks with a total capacity of 300 m3. A pumping station, an acid mixing system and two HCL vapour scrubbers will soon be added.
GuangDong, China, May 2018.
TECHLINK designed and produced near three hundred polypropylene control valves in a record time to meet the deadline of the contruction project of the World’s current largest plant of battery chemicals.
Battery chemicals are an essential commodity of the Renewable Energy era. The markets for electric cars and energy storage facilities are rapidly expanding, promoting large investments in this specialty.
This trend changed the scale of the requirement for accurate, corrosion resistant, control valves made of solid polymers.
Sumatera, Indonesia, December 2017. TECHLINK replaces two large heat exchangers for black liquor in one of the World’s largest Pulp & Paper Mill.
The black liquor concentrators were built some twenty years ago by a Spanish company. Over the years, some tubes leaked, other collapsed, resulting to an unacceptable drop in machinery performance. TECHLINK’s China branch remanufactured two new heaters of 45 tons each and organized the tricky logistic right up to the mill site.
Three years after the feasibility study was complete, Vientiane’s first fecal sludge treatment plant in Nahai (Xaysettha District) has officially launched. The FSTP This is the world’s first plant to use an innovative treatment process based on planted reed beds to separate the solid part of the sludge while enabling the elimination of pollution through an aerobic biological process. After some time, the accumulated layer of humus created on the surface of the beds is removed, dried and can be sold as a fertilizer. TECHLINK contributed by engineering submerged valves that could resist corrosion inside and outside on the long term.
Laos, December 12th 2017. Three years after the feasibility study was complete, Vientiane’s first fecal sludge beneficiation plant in Nahai (Xaysettha District) is operational.
Dahej, India, December 2015
Successful commisionning of TECHLINK non-metallic control valves at a fluorochmical plant in Gujarat.
The plant manufactures refrigerants and fluoroplatics. The control valves had to face the challenge of controlling the flow of concentrated hydrochloric acid through a two-hundred meter pipeline of small section. The valves, of the V-port ball type, and entirely made of PVDF, had to be designed to take the large head loss of the pipeline into account. Objective achieved !
October 2016. TECHLINK China branch supplies and automates thirty-five critical safety related valves for liquid chlorine, of the famous brand (France) to two potassium hydroxide plants in Jiangsu province, China.
This project was made possible by a close cooperation between the French supplier of chlorine valves, TECHLINK, and Chinese automation components suppliers.
Indonesia, October 2017. One of the largest paper pulp mills in the World has trusted TECHLINK for the replacement of two giant black liquor heaters of 50 tons each.
Black liquor is collected after wood chips are digested to produce paper pulp. The liquor is a thick liquid looking like crude oil, and which can indeed be used as fuel in a power plant. But it first needs to be concentrated and dehydrated which is done in large heaters. The existing heaters were ten years old and needed to be replaced. TECHLINK was requested to improve the design of the heaters to avoid the progresive loss of performance suffered by the existing devices.
Yeosu, Korea, February 2016. LG-Chemicals PVC unit reports eighteen months of continuous operation of the dirty service EDC intercooler without any cleaning.
The « Rectangular Channels » heat exchanger built by BARRIQUAND, France, was installed in October 2014 as part of an Energy Saving Program. It recovers the heat from the EDC distillation column. The extreme fouling conditions of the crude EDC was the challenge that the unique technology of BARRIQUAND perfectly met. The intercooler has not been cleaned for eighteen months, and still operates near full capacity. Previous technologies required cleaning every two months.
Changsu, Jiangsu, China, 13th & 14th November 2015
For the fourth year in a row, TECHLINK extends its assistance to chemical company Arkema to tighten the flange bolts of a highly sensitive piping system involved in the manufacturing of refrigerants.
The system contains dangerous HF chemicals and operates at high temperatures. Flanges leaks were experienced until TECHLINK introduced the hydraulic extension bolt tightening technique to the plant in 2012.
October 2016. TECHLINK organizes the reconditioning and re-lining of a twenty-five years old ion exchange resin bed column belonging to a chlorine plant in North Thailand.
The column has been entirely stripped and sand blasted. Damages due to corrosion are repaired and a fresh rubber lining is applied at a specialized facility in Gujarat, India. To preserve the purity of the brine, the rubber contains less than 300 ppm of calcium and magnesium.
Beijing, China, October 2015. The 4th China International Chlor Alkali conference was held in Beijing last October.
