Refinery & Oilfield Chemicals

What refinery and oilfield chemicals are

Dyna Glycols manufactures demulsifier intermediates and corrosion-inhibitor bases for crude production, transport and refining. Demulsifier resins are alkyl phenol-formaldehyde ethoxylates at defined %EO, plus propylene glycol EO/PO copolymers and diethylene triamine EO/PO alkoxylates. Inhibitor bases are tallow amine/diamine 10 EO and a 70% amido-imidazoline (Product CND).

These are intermediates for blender packages. They are not finished field demulsifiers with a guaranteed bottle test on every crude. Send the crude, water cut, temperature and the bottle-test method so a resin %EO can be shortlisted. APEO-containing resins remain catalogue items; say if they are banned.

How Dyna Glycols manufactures refinery and oilfield chemicals

Nonyl and dodecyl phenol-formaldehyde resins are ethoxylated to about 20–48% EO as listed. PG and DETA alkoxylates are run on the EO/PO plant. Amine ethoxylates and imidazoline are finished as on the metal/oilfield inhibitor pages.

Custom %EO on a resin and custom EO/PO on PG or DETA are quoted after the existing bottle-test winner and annual volume.

Typical grades in this range

Name demulsifier resin vs EO/PO intermediate vs inhibitor base. Typical catalogue points are listed below.

• Nonyl phenol-formaldehyde resin ethoxylates at about 20%, 30%, 40% and 48% EO
• Dodecyl phenol-formaldehyde resin ethoxylates at about 30% and 40% EO
• Propylene glycol propoxylated/ethoxylated (EO/PO copolymers)
• Diethylene triamine propoxylated/ethoxylated
• Corrosion inhibitors: tallow diamine 10 EO / tallow amine 10 EO (100% active); Product CND 70% amido-imidazoline

Where refinery and oilfield chemicals are used

Crude dehydrating and desalting use resin ethoxylates as the oil-soluble backbone of a demulsifier blend, often with an EO/PO copolymer or amine alkoxylate as a water-drop or wetting companion. %EO moves the partition between oil and the interface. Low %EO stays more oil-soluble; higher %EO moves toward the water.

Inhibitor packs for drilling, production, pipelines and refining use the amine ethoxylate as a film-forming detergent base and the imidazoline (often acid-salted) as a filming amine. See also the metal and electroplating page for the same inhibitor bases.

How to specify refinery and oilfield chemicals

For demulsifiers send crude API, water cut, temperature, asphaltene/wax notes, APEO policy and the bottle-test method (including solvent). Name NP vs DP resin and target %EO if known.

For inhibitors send water vs oil continuous, acid for imidazoline conversion, H2S/CO2/brine and % active. Attach the incumbent TDS.

Quality, documents and supply

Lots are released against %EO or hydroxyl, viscosity, pH, water and appearance as on the TDS. SDS and COA follow verification. Bottle tests and corrosion coupons are customer or blender tests on the actual crude or brine.

Warm resin ethoxylates until uniform. Follow the SDS. APEO resins and concentrated amines require the stated PPE.

Practical notes on refinery and oilfield chemicals

A 20% EO NP resin is not a drop-in for a 48% EO resin. Partition and water drop change. Shortlist two %EO points rather than one trade name.

DP resins vs NP resins change asphaltene handling on some crudes. They are not assumed copies at the same %EO.

Imidazoline acid salts are water-soluble; the 70% base may not be. Freeze the acid.

English is the source language for %EO and APEO claims.

Once a trial blend is approved, freeze resin type, %EO and the EO/PO companion so later intermediates match the evaluation.

Ordering and evaluating refinery and oilfield chemicals

Send the application, the analytical window and the pack size when you request a laboratory sample of refinery and oilfield chemicals. SDS, TDS and COA follow a short company check. Handle and store the grade as the SDS describes.
