Chemical

Thanks for your interest in Aartech’s offerings to the chemical industry. Whether you are a chemical industry professional, consultant, EPC contractor, project planner, system integrator or research / design / operation / maintenance / testing / commissioning engineer, we hope that you find our solutions of interest and look forward to hear from you.

The chemical industry has rapidly expanded to support the ever increasing demands of  array of chemicals in direct or indirect use in the economy. While the technologies for running such plants and their interconnected logistics have matured tremendously over the years, there continue to be several key concerns in its operations. There is a very high focus today on improved plant utilizations with heightened revenue consciousness, bottom-line efficiencies, productivity benchmarks and system improvement requirements.

PROCESS CONTINUITY

In a typical chemical plant installation, there are many operations of periodic as well as continuous nature with varying process time constants during which it may be a critical requirement for some of the electrical loads, such as pumps, motors, compressors, electrolysers, batch separators etc. to be supported with electrical power. Many plants have their own captive power for inhouse consumption, reliable power availability to critical processes, improved power quality as well as power export which may operate in grid connected or islanded configuration. Thus it is important to maintain the process continuity of all the critical auxiliaries in the plant in the event of a contingency. With an experience of over 100’s of installations and decades of service, Aartech’s BTS 2000 Fast Bus Transfer Systems provides proven advanced numerical microprocessor based fast bus transfer solutions of ensuring safe and reliable bus transfer operations with the best international benchmarks. These systems are employed in various configurations depending on the design, operational philosophy, economy and wish-list of the end user although a three breaker main-tie-main configuration is the most typical. While traditionally, these schemes have been applied to only the critical boards, they are increasingly being considered for other switchboards including LT switchboards as well to establish a more robust and redundant operation in plants.

Aartech is established and recognized in the field of bus transfer internationally, with several internationally published papers, approvals from major switchgear manufacturers, consultants, turnkey EPC contractors as established with performance certificates from our esteemed end users.

Aartech’s paper on Fast Bus Transfer Systems for Critical Process Continuity was presented at IEEE’s Industry Applications Society’s PCI – Petroleum and Chemical Industry Conference at New Delhi, India in 2004 and well received by industry peers.

CONTROL & AUTOMATION

Aartech’s Control & Relay Panels (CRP) SSD is organized to offer specialized custom built, integrated software engineered solutions involving aspects of protection, metering, communications and control for distributed automation, SCADA and remote telemetry based control and automation solutions.

RELIABLE ENGINE STARTING

Backup DG Sets are the last line of defense against a total AC failure. However, it is observed that they may not operate on demand due to problems in the batteries, maintenance issues etc. Similarly fire engines are considered a very critical fire safety protection in such installations.

Aartech’s KranKing Utlracapacitors can provide reliable engine starting solutions to ensure robust electrical support to the batteries at the time of engine cranking. A portable jump start system can also effectively provide for an arrangement to support the operations of multiple DG sets in a DG plant.

FAULT CURRENT LIMITING

Fault levels of the MV switchboards may get compromised during re-configurations / capacity additions or operational considerations such as closing of tie breakers and grid interconnections. Even having fault levels within breaker handling capabilities, there is a considered need to reduce the fault energy, for eg. in the event of a transformer fault where severe consequential damages have been known to happen.

Aartech’s fault current limiting solutions provided as a value added system integrator of M/s G&W USA offers internationally proven CLiP® Fault Current Limiter to customers all over Asia.

Aartech has successfully commissioned fault current limiting solutions in chemical plants undergoing expansions and upgradations in the Asia in 2011.

LOAD LIMITING

The control arrangements in the industry are naturally elaborate and extensive. Usually, circuit faults in the control wiring are handled by use of HRC fuses or MCBs. Both require manual intervention for restoration.

Aartech’s load limiter system solutions in the form of Load Checker can act as an automatic resettable control fuse and thus provide for minimum downtime and repair/replacement costs and efforts.

PROTECTION

A complete range of powerful yet economic, state-of-the-art microprocessor based protection solutions for a variety of standard feeder, transformer and motor protection as well as special customer defined schemes that require integration of features such as standard protection with special requirements such as islanding, bus transfer, load shedding, synchronization, SCADA interface and automation, developed through international collaboration are offered by Aartech’s Relay SSD.
