Instrumentation Solutions for Quench Tower and Settler Level Measurement

The ethylene production process begins with unprocessed material, or feedstock. Feedstock enters the plant and goes through the ethylene furnaces, in a process known as pyrolysis. Once it is cracked into a variety of hydrocarbons and hydrogen, it immediately begins to recombine into larger molecules. To prevent these reactions and stop the recombination, the cracked vapor goes through a quench tower to cool using oil or water. The largest hydrocarbons are carried with the water into the quench settler or the quench water separation drum (QWSD). As feedstock is increased, more cooling fluids are required.

Level Measurement Solutions for Chemical Condensers

Condensation is the heat transfer process that changes a gas or vapor to a liquid. It is employed in the reflux process to improve the efficiency of distillation. Condensation can also be employed for producing saturated liquid products, for sub-cooling, or to serve an environmental or vapor recovery function. Condensation is carried out in a variety of configurations. By properly monitoring chemical condensers, plants can ensure that distillation and other processes run as efficiently as possible.

Level Solutions for Chemical Industry Reboilers

Reboilers, or vaporizers, are heat exchangers that provide heat to the bottom of a distillation tower. They boil the bottom liquid to generate vapors which are returned to the tower to drive the distillation separation process.

Redundant Level Measurement for Chemical Overfill Prevention

In the chemical industry, level instrumentation is required to measure continuous liquid levels in flammable tanks and to prevent potential overfill. Chemical plants stringently enforce environment, health, and safety (EH&S or HS&E) management practices with the expectation that their suppliers have a similar culture.
