Process
Plants
EN Engineering
has an experienced background in the design, procurement and
construction management of various types of natural gas process
facilities. The majority of these facilities have been installed
at storage fields to meet gas quality specifications.
ENE has designed gas
separation, dehydration and gas cooling systems for the removal of liquid
hydrocarbons and water. A wide variety of systems have been designed for the
removal of liquids from gas inlet streams, including centrifugal, coalescing,
filter and three phase separators and slug catchers. The design of atmospheric
tank storage systems have ranged from small to medium in size. Dehydration
facilities installed for past projects have included mole sieve, glycol and
solid desiccant types. Gas cooling has been installed in conjunction with
compression facilities.
ENE’s experience also
includes gas treating facilities for the removal of CO2 and H2S alone with all
necessary supporting control systems for the purification plants.

Corrosion Control 
The team of
NACE-certified corrosion professionals at EN Engineering has been
designing, upgrading and maintaining the corrosion control
requirements of transmission, distribution and storage facilities
for many large pipeline and distribution companies for more than
50 years. ENE has recognized experts in all aspects of cathodic
protection. We can provide this experience and expertise to you
on your distribution system.
ENE’s certified
professionals can provide corrosion testing, research, materials
evaluation and qualification, consulting and failure analysis.
Our expertise is geared toward companies in oil and gas,
petrochemical and public utility operations.
REGULATORY
COMPLIANCE TESTING
Recent
security-related incidents have raised safety concerns specific to
gas pipelines. Given this situation, there is and will continue
to be increased scrutiny by government agencies regarding security
issues for pipelines. ENE will help you comply with these
regulations at each step of the operations process. We will
provide you with up-to-date knowledge of pipeline integrity
analysis, and will design the appropriate program for you to meet
governmental regulations and standards. 5
