LANXESS, a leading specialty chemicals company, announced the construction of a new butyl rubber plant in February 2008, located on Jurong Island, Singapore. Sitting on a 200,000 square metre plot of land, the new facility will process 100,000 tons per annum and LANXESS has allocated a total Eur 400 million for this investment.
The plant will serve the rising demand for tires that is being driven by the trend towards greater mobility, in particular among the growing middle-class in countries such as China and India. In addition, the distinct properties of butyl rubber make it an important product of choice for the pharmaceutical industry, particularly in Asia.
LANXESS leased the plot from the JTC Corporation, an authorised agent of the Singapore Ministry for Trade and Industry. Around 1,500 workers have been employed on the construction site at peak times, and in January 2012 the company celebrated four million man hours without lost time injury at the plant. Some 200 highly-skilled jobs will be created when the new facility is operational in Q3, 2013.
The neighboring Shell petrochemical refinery has been contracted to supply the feedstock for the key raw material, isobutene.
The new facility will manufacture halobutyl rubber and conventional butyl rubber. Both butyl and halobutyl rubber are impermeable to air, other gases and liquids.
The main applications for conventional butyl rubber are hoses and tires, but it is also one of the base materials for making chewing gum.
Halobutyl rubber is mainly used for the inner liners of tubeless tires. One special application is the manufacture of caps for pharmaceutical products that have to be reliably protected against moisture.
The company carried out a complete evaluation of the existing process to manufacture butyl for the new Singapore facility and a radical redesign was implemented. The process, which draws on LANXESS’ long history of rubber expertise, will be best in class, the company says, with state-of-the-art power management and monitoring systems installed.
LANXESS’s key objectives for the butyl plant were to be more energy and resource efficient, and also more environmentally friendly. The project team recognised at the outset that the plant’s lighting solution would play an important role in achieving these objectives.
The challenge was to find suitable light fixtures that were certified for use in hazardous environments, would deliver reliable lighting in normal and emergency mode operation, and would meet the requirements for reduced energy consumption and reduced maintenance.
In addition, the lighting had to meet the Singapore Standard SS 531, which recommends lux levels for different areas within a facility, and the Green Mark requirements in SS 530 which define the power consumption per square metre that must be achieved in order to be considered energy efficient.
During the detailed engineering phase, Johannes Goertz, the LANXESS PCT Project Manager, also highlighted their special requirements for emergency lighting. Dialight was able to modify the design of the LED lighting fixtures with built in battery backup to meet company requirements.
Goetz told HazardEx there were two main hazardous environment considerations. Firstly, that the lighting fixtures should have good protection against lightning, and to be suitable for Zone 1,2 in process areas. Secondly, the installation should have IP65/IP55 protection against dust and water ingress
The original design for the facility featured a mix of fluorescent T8s and metal halide fixtures, but in 2010, LANXESS gave Dialight the opportunity to propose a new lighting design featuring its LED lighting technology and the benefits immediately became apparent.
Dialight provided the lighting design to convert the conventional lighting for indoors and outdoors areas to LED products for both non-hazardous and hazardous application, where LANXESS was able to save a significant amount of energy while complying with the SS 531 and SS 530 specifications. The decision to use LED lighting throughout the five major production areas of the facility was made simple with the 5-year performance warranty from Dialight which would result in eliminating the burden of maintenance.

By converting to LED lighting, LANXESS saw its energy consumption and carbon emissions reduced by 55%. The low operating temperature of the LED fixtures was also a health and safety benefit, as it removed the risk of burn injury common with metal halides for anyone who might come into contact with the fixture.
In Singapore, the Dialight LED benefit of built-in surge protection is also an important advantage during the rainy season from October to December. The region is prone to lightning strikes which can cause surges, resulting in the burnout of unprotected fluorescent ballasts and the consequential expense of maintenance.
The latest state-of-the-art LED lighting fixtures from Dialight were used, both ATEX and IECEx-certified for use in the relevant hazardous areas.
LANXESS is a leading speciality chemicals company with sales of EUR 8.8 billion in 2011 and currently around 17,100 employees in 31 countries. The company is currently represented at 49 production sites worldwide. The core business of LANXESS is the development, manufacturing and marketing of plastics, rubber, intermediates and specialty chemicals.
