Honeywells OneWireless solutions, improves process plant bottomlines

With a large processing plant that is spread across a wide
area, Reliance Industries was experiencing challenges with
obtaining reliable tank level and temperature readings at its
olefins plant in Gujarat, India. As the largest private sector
company in India, Reliance recognized the business
potential of moving to a wireless monitoring system. The
issue stemmed from tapping transmitter signals of tank
levels and temperatures from some of the farthest crude
spheres in the petrochemical complex. The existing wired
application was remotely located and required continuous
troubleshooting and maintenance.

Reliance implemented Honeywell’s OneWireless™ solutions
at the Gujarat refinery to gain control of data, streamline
tasks and improve overall efficiency.Some of the benefits from
implementing OneWireless include Improved employee safety
by eliminating manual level monitoring. Avoid prohibitive
wiring costs and reduced installation, operational and
maintenance costs.Increased reliability and data accuracy,
helping to meet and maintain regulatory compliance.
Improved production efficiency through more accurate
data. Improved quality of data to enable better decision
making. Reduced maintenance requirements compared to wired
transmitter alternative.

Bettis gas/hydraulic actuators automate pipeline valves

Valve Automation is recognized worldwide for the reliability of its actuators under the most demanding conditions. The gas/hydraulic products epitomize the quality and performance required for controlling high pressure natural gas pipelines in remote locations and under severe climatic conditions.Bettis gas/hydraulic actuators are used to automate valves located on gas transmission pipelines, often travelling hundreds of miles through remote areas, where there are no low pressure instrument air or high pressure hydraulic supply lines available.The gas/hydraulic actuators operate using pressurized gas from the pipeline as its power source, requiring reliability and safety features built into the valve operator system. Since the line gas is a potential hazard, Bettis actuators use a clean, nonexplosive hydraulic fluid as an oil barrier rather than direct line gas.

Some of the salient features include High torques and thrusts. Rotary quarter-turn models have torques upto 6,000,000 lb. in (678,000 Nm)and linear models with thrusts up to 650,000 lbs(2,891,200 N). They are most adaptable for all types of gas compositions including sour(NACE)and wet gas. Standard operating temperature is -50°F to 150°F (-46°C to + 66°C)and Standard operating pressure is upto 1,440 PSIG.
