Sep 26, 2018 – Ti-Cons signs a Heads of Agreement with TNG Limited, Australia

Ti-Cons Weiland und Partner signed with Australian company TNG Limited (see a Binding Heads of Agreement for the supply of a know-how package for a TiO2 pigment plant.

The raw material for the TiO2 pigment plant is produced by the TIVAN® process, developed and owned by TNG, which produces, next to TiO2, high-purity vanadium pentoxide (V2O5). The TiVAN® process is described here:

Ti-Cons intends to provide a commercial contract for the above-mentioned technology package including engineering, construction/procurement support, training and commissioning.

Apr 27, 2018 – Ti-Cons made presentation at 2018 TiO2 conference of Jinzhou

Jan 26, 2018 – Interview of Managing Partner Christian Weiland by Industrial Minerals

During the 2017 Annual Meeting of China TiO2 Industry in Chongqing on November 18-20, 2017, Christian Weiland, the managing partner of Ti-Cons, was interviewed by Mr. Albert Li from Industrial Minerals.

Photos of the conference can be viewed here.

The interview can be read here and down here:

1. What does Ti-Cons do?

We are consultants and technology provider for the production of TiO2 pigment using both the sulphate and the chloride route including the necessary post treatment. We deliver the necessary engineering for construction, train the staff of the customer, do the start-up and provide after sales support.

2. Why did you come to China to attend this TiO2 meeting in Chongqing?

Ti-Cons has successfully implemented the chloride process (CP) with two Chinese leading companies already, which are Yunnan Xinli and Lomon Billions in the past few years. We attended this meeting to meet TiO2 producers which are interested in our technological expertise.

3. What do you think of the Chinese TiO2 industry?

Right now, the Chinese government is not only encouraging CP technology which is more efficient, costs less energy and produces less wastes compared to traditional sulphate TiO2 technology, but also is conducting severe environmental protection inspection throughout the year and it will get stricter.

In addition, CP technology has always been dominated by competitors outside China, and the Chinese producers are working hard for breakthrough but the status is not satisfactory right now. Now there are only four producers in China using CP technology but their output is very small compared to the sulphate route.

4. What is the position for Ti-Cons in China?

We think now is a good time for Ti-Cons to strengthen our position in China as we are the only successful TiO2technology provider, at least for CP, and more TiO2 companies are in talks with us, either needing consulting services or willing to establish a future cooperation.

5. What are the changes in recent years in the TiO2 industry?

We can really see that environmental inspection had a great impact in the TiO2 industry in China. In the past, when talking to a producer, we were asked “what is the fee for the technology, is it expensive, we don’t have enough fund, etc” and environmental aspects came afterwards. But now, people will ask us first “how effective can your technology deal with wastes and by-products?”. Now they care more about environmental issues than investment, but of course this is related to the good profits they made since 2016 when TiO2 price kept rising. Let me note that our technology is state of the art regarding the environment too.

Sep 26, 2017 – Partner Dr. Matthias Jendro deceased

We, the partners of Ti-Cons, have a sad news to share. Dr. Jendro lost his fight against cancer and passed away on August 22, 2017.

Dr. Lailach and Dr. Jendro founded Ti-Cons in 2005 with the vision to offer the knowhow for the production of TiO2-pigment in China and to implement the first high-end CP plant in the PRC. The first projects were knowhow transfers in the area of SP and were very useful for him to understand the country and the local industry. In 2007, Dr. Jendro, C.J. Weiland and Dr. Fan could sign the first contract for the new CP plant, including PT, of Yunnan Xinli. The contract included the delivery of the detail engineering for CP, the basic engineering for PT, training, start-up and after sales support for a 60.000 tpy plant in Lufeng, Yunnan. In 2012, the second contract for the CP plant, including PT as well, was signed with Henan Billions (HB) for their 100.000 tpy plant in Jiaozuo. The scope of the delivery was similar to Xinli. In 2013, the plant of Xinli was successfully started up by Dr. Jendro and his partners. In 2015, the start-up of the plant of HB was completed by Dr. Jendro and his partners and the line is producing since then appreciable amount of product with, for China, unreached quality.

Ti-Cons will honor his memory by dedicating ourselves to continue the work of the “pioneer of CP technology in China”.

In a process, initiated by Dr. Jendro in 2016, Ti-Cons will strengthen their organization and their technology even more to meet the increasing demand of the world market.

May 25, 2017 – Ti-Cons made presentation at a TiO2 conference in Jinzhou

Ti-Cons took part on April 20-22, 2017 at the „2017 International Titanium Industry Green Manufacturing and Material Conference“.

Ti-Cons was made a presentation with the title “Implementation of German CP Technology in China”.

Mar 06, 2016 – Cooperation with ENFI

Ti-Cons is pleased to announce the signature of a cooperation agreement with China ENFI Engineering Company, Beijing.

ENFI and Ti-Cons have successfully worked together for several years now. ENFI was part of both of our chloride projects and extended their expertise and responsibility in CP over the years. The cooperation which both sides committed to now was the next step to do.

The two parties will cooperate all over the world and exclusively for the Chinese market.

The field of cooperation includes the chloride process (CP) and the related post-treatment (PT) process. The cooperation can also include the sulphate process (SP).

The two parties will develop a common marketing and combine their products and services to satisfy the requirements of the market.

ENFI and Ti-Cons are sole project partners to each other for cooperation in China regarding the implementation of Ti-Cons’s CP technology for new lines. Project cooperation of new lines includes technology package, engineering, equipment supply, construction, training and commissioning.
