Oil/Gas Unit
(CO & H2 Production)
Oil/Gas Unit Summary
This unit produces carbon monoxide (which is a feedstock for the DMF
production process) by the partial oxidation of natural gas in oxygen using
Texaco gasification technology. Natural gas is supplied by pipeline from Transco
(via Terra), and oxygen is supplied by pipeline from BOC. The Oil Gas Plant is
located in the north-eastern corner of the site. By-products of this reaction are
hydrogen and carbon dioxide. Carbon dioxide is removed with potassium
carbonate solution (Benfield CO2 removal process) and vented, while the
hydrogen is either flared-off or sent by pipeline to Terra for use as a fuel in its
ammonia plant. Further separation is performed with membranes to achieve a
70/30 mix of CO/H2. Arsenic trioxide (a corrosion inhibitor) is used within the Oil
Gas Plant as a coating to the majority of the finishing process equipment.

Methyl Amines Unit
(Mono, Di and Tri Methyl Amines Production)
Methyl Amines Unit Summary
This is a CONTINUOUS operation and is the heart of the plant and is by far the
largest unit with a capacity of 46,000 MTA mixed amines production. This unit
produces monomethylamine (MMA), dimethylamine (DMA) and trimethylamine
(TMA) from the reaction of methanol and ammonia. Methanol and Ammonia is
delivered via pipeline from a Terra site Methanol storage area and from Terra’s
ammonia plant. Up to approximately 1,800 tons of methylamines (anhydrous and
aqueous) are stored at the site in 13 large above ground bulk storage tanks,
situated adjacent to the plant in the north-western area of the site.

Higher Amines Unit
Higher Amines Unit Summary
This unit takes the “lower” amines from the Methyl Amines plant and attaches
them to a higher molecular weight molecule such as Ethanol, I-Propanol and
Butanol. This is followed by hydrogenation in a 300 PSIG shell and tube carbon
steel reaction vessel with catalyst. Separation follows in a series of six columns
and evaporators. The wiped film evaporator in this unit has never been used.
Di-methyl Formamide Unit (DMF)
DMF Unit Summary
DMF is a CONTINOUS operation produced by the reaction of DMA (from the
Methylamines Plant) and carbon monoxide (from the Oil Gas Plant) at a capacity
of 24,000 MTA. The DMF Plant is located between the Methylamines Plant and the
Oil Gas Plant at the northern area of the site. Approximately 800 tons of DMF is
stored at the site in two large tanks, located adjacent to the north side of the
plant. Sodium methoxide (received as a solution in methanol) is used as a
catalyst in the manufacture of DMF.

Di-methyl Amine Ethanol (DMAE) Unit
DMAE Unit Summary
This unit has CONTINUOUS front end and a BATCH distillation operation. This
derivatives unit produces DMAE by the reaction of DMA (piped from methylamines
plant) and ethylene oxide (EO) at a capacity of 7,000 MTA. Crude DMAE is purified
in a continuous distillation unit. The resulting product is then stabilized by
hydrogenation in the hydro-refining column using a Palladium catalyst.
Approximately 700 tons of DMAE is stored at the site in eight large tanks, located
to the north and south of the plant.

Choline Chloride Unit
(Vitamin B12 for Chicken Feed)
Choline Chloride Unit Summary
This unit has BATCH front end (reaction) and a CONTINUOUS distillation operation.
This derivatives unit produces Choline Chloride at the rate of 14,000 MTA by the
reaction of TMA (from Methylamines Plant) with hydrochloric acid and then EO in a
glass lined, batch reactor. Crude choline chloride is purified in a continuous glass
distillation column. Piping in this plant is primarily glass lined or Titanium. Heat
exchangers are primarily carbon block. Approximately 200 tons of aqueous choline
chloride is stored at the site in four tanks, located adjacent to the west side of the
plant. Hydrochloric acid is stored in a tank, adjacent to the east side of the plant.
