Hydrocarbon Solvent Tanks, 50, 75 and 100 LB, ASME and Non-ASME

Jacketed hydrocarbon solvent tanks built in Bend, Oregon, in three sizes. 100 LB ASME code stamped, $28,750. 75 LB non-ASME, $18,750. 50 LB non-ASME, $17,550. All three are 250 psi (17.2 bar) MAWP with an electropolished interior, a 180 grit electropolished exterior and a cooling jacket.

Buy the 75 or the 100. The 50 LB is listed because people ask for it, but it is only $1,200 cheaper than the 75 and holds a third less solvent. Shops that buy the 50 come back wanting the bigger one, and a second tank costs far more than the $1,200 they saved.

Two 75 LB tanks are built and on the floor right now. If your jurisdiction, insurer or inspector asks for a code stamped pressure vessel, buy the 100 LB.

WHICH SIZE

BUILT, NOT RESOLD

• N.B. Oler holds the ASME U stamp. The 100 LB is welded, hydro tested and stamped in our own shop.
• 100 LB design calculations are 3P Certz report DCR-200101-R1, released 13 January 2021, to ASME BPVC Section VIII Division 1, 2019 edition. Registered in Canada as CRN R8694.5.
• The 75 LB traces to 3P Certz report ECR-180053-R0, released 21 December 2018, covering the 60 to 75 lb solvent tank.
• Non-stainless parts, meaning gaskets and seals, are purchased and are not represented as ours.

SPECIFICATIONS

Figures come from the design and certification reports, not a brochure. Common to all three sizes: 250 psi (17.2 bar) MAWP, certified on the 100 LB at 200 F (93 C), MDMT -155 F (-104 C), a 100 psi (6.9 bar) jacket, cooling by liquid CO2 or process chiller, SFA 5.9 / ER308L weld filler, zero corrosion allowance, 0.6 joint efficiency, electropolished mill finish inside, 180 grit electropolished outside, and jacket protection of a 100 psi (6.9 bar) cryogenic relief on the jacket, 22 psi (1.5 bar) on the inlet and a 1/2 in cryogenic needle valve. One crate, 80 in long x 16 in wide x 22 in tall at 600 lb, covers all three sizes. What changes by size:

Top caps are built to the port arrangement your system uses and quoted by email rather than sold from this page. Same for custom fittings, jackets and dimensions.

FITS

• The 100 LB is the tank fitted to the 20 LB system, and the 40 LB Double Barrel runs two of them.
• Buy any size as a second tank so one fills while the other runs, or to replace a legacy 50 lb or 200 lb tank.
• A material column rack can be ordered with a 100 LB ASME tank already on it.
• Butane, propane and blends. Not for ethanol service.

LEAD TIME AND TERMS

• Usually in stock. If yours has to be built, 20 weeks is the maximum.
• Paid in full before it ships. We do not offer net 30 or purchase order terms.
• Ships LTL freight. Freight is quoted and invoiced after the crate is measured, not charged at checkout.

CONSUMABLES

The high flow Conrader SRV530 goes on top of the solvent tank and nowhere else on the system, because in an emergency the largest volume has to dump pressure fastest. The jacket reliefs are cryogenic PRVs, 100 psi (6.9 bar) on the jacket and 22 psi (1.5 bar) on the inlet, on a 3 to 6 month replacement schedule. Gaskets are Viton, also 3 to 6 months. A solvent tank condenser speeds recovery back into the tank.
